Guide to 3D Printing Materials: Types, Applications, and Properties

3D printing empowers you to prototype and manufacture parts for a wide range of applications quickly and cost-effectively. But choosing the right 3D printing process is just one side of the coin. Ultimately, it'll be largely up to the materials to enable you to create parts with the desired mechanical properties, functional characteristics, or looks.

This comprehensive guide to 3D printing materials showcases the most popular plastic and metal 3D printing materials available, compares their properties, applications, and describes a framework that you can use to choose the right one for your project.

There are dozens of plastic materials available for 3D printing, each with its unique qualities that make it best suited to specific use cases. To simplify the process of finding the material best suited for a given part or product, let’s first look at the main types of plastics and the different 3D printing processes.

There are the two main types of plastics:

• Thermoplastics are the most commonly used type of plastic. The main feature that sets them apart from thermosets is their ability to go through numerous melt and solidification cycles. Thermoplastics can be heated and formed into the desired shape. The process is reversible, as no chemical bonding takes place, which makes recycling or melting and reusing thermoplastics feasible. A common analogy for thermoplastics is butter, which can be melted, re-solidify, and melted again. With each melting cycle, the properties change slightly.

• Thermosetting plastics (also referred to as thermosets) remain in a permanent solid state after curing. Polymers in thermosetting materials cross-link during a curing process that is induced by heat, light, or suitable radiation. Thermosetting plastics decompose when heated rather than melting, and will not reform upon cooling. Recycling thermosets or returning the material back into its base ingredients is not possible. A thermosetting material is like cake batter, once baked into a cake, it cannot be melted back into batter again.

The three most established plastic 3D printing processes today are the following:

• Fused deposition modeling (FDM) 3D printers melt and extrude thermoplastic filaments, which a printer nozzle deposits layer by layer in the build area.

• Stereolithography (SLA) 3D printers use a laser to cure thermosetting liquid resins into hardened plastic in a process called photopolymerization.

• Selective laser sintering (SLS) 3D printers use a high-powered laser to fuse small particles of thermoplastic powder.

Fused deposition modeling (FDM), also known as fused filament fabrication (FFF), is the most widely used form of 3D printing at the consumer level, fueled by the emergence of hobbyist 3D printers. 

This technique is well-suited for basic proof-of-concept models, as well as quick and low-cost prototyping of simple parts, such as parts that might typically be machined.

Consumer level FDM has the lowest resolution and accuracy when compared to other plastic 3D printing processes and is not the best option for printing complex designs or parts with intricate features. Higher-quality finishes may be obtained through chemical and mechanical polishing processes. Industrial FDM 3D printers use soluble supports to mitigate some of these issues and offer a wider range of engineering thermoplastics or even composites, but they also come at a steep price.

As the melted filament forms each layer, sometimes voids can remain between layers when they don’t adhere fully. This results in anisotropic parts, which is important to consider when you are designing parts meant to bear load or resist pulling.

FDM 3D printing materials are available in a variety of color options. Various experimental plastic filament blends also exist to create parts with wood- or metal-like surfaces.

The most common FDM 3D printing materials are ABS, PLA, and their various blends. More advanced FDM printers can also print with other specialized materials that offer properties like higher heat resistance, impact resistance, chemical resistance, and rigidity.

Stereolithography was the world’s first 3D printing technology, invented in the 1980s, and is still one of the most popular technologies for professionals.  

SLA parts have the highest resolution and accuracy, the clearest details, and the smoothest surface finish of all plastic 3D printing technologies. Resin 3D printing is a great option for highly detailed prototypes requiring tight tolerances and smooth surfaces, such as molds, patterns, and functional parts. SLA parts can also be highly polished and/or painted after printing, resulting in client-ready parts with high-detailed finishes.

Parts printed using SLA 3D printing are generally isotropic—their strength is more or less consistent regardless of orientation because chemical bonds happen between each layer. This results in parts with predictable mechanical performance critical for applications like jigs and fixtures, end-use parts, and functional prototyping.

SLA offers the widest range of material options for plastic 3D printing.

SLA 3D printing is highly versatile, offering resin formulations with a wide range of optical, mechanical, and thermal properties to match those of standard, engineering, and industrial thermoplastics.

Selective laser sintering (SLS) 3D printing is trusted by engineers and manufacturers across different industries for its ability to produce strong, functional parts. Low cost per part, high productivity, and established materials make the technology ideal for a range of applications from rapid prototyping to small-batch, bridge, or custom manufacturing.

As the unfused powder supports the part during printing, there’s no need for dedicated support structures. This makes SLS ideal for complex geometries, including interior features, undercuts, thin walls, and negative features. 

Just like SLA, SLS parts are also generally more isotropic than FDM parts. SLS parts have a slightly rough surface finish due to the powder particles, but almost no visible layer lines.

SLS 3D printing materials are ideal for a range of functional applications, from engineering consumer products to manufacturing and healthcare.

The material selection for SLS is limited compared to FDM and SLA, but the available materials have excellent mechanical characteristics, with strength resembling injection-molded parts. The most common material for selective laser sintering is nylon, a popular engineering thermoplastic with excellent mechanical properties. Nylon is lightweight, strong, and flexible, as well as stable against impact, chemicals, heat, UV light, water, and dirt.

High performance composites on high cost industrial machines	Varieties of resin (thermosetting plastics). Standard, engineering (ABS-like, PP-like, flexible, heat-resistant), castable, dental, and medical (biocompatible).	Engineering thermoplastics. Nylon 11, Nylon 12, and their composites, thermoplastic elastomers such as TPU.

Beyond plastics, there are multiple 3D printing processes available for metal 3D printing. 

• Metal FDM

Metal FDM printers work similarly to traditional FDM printers, but use extrude metal rods held together by polymer binders. The finished “green” parts are then sintered in a furnace to remove the binder. 

SLM and DMLS printers work similarly to SLS printers, but instead of fusing polymer powders, they fuse metal powder particles together layer by layer using a laser. SLM and DMLS 3D printers can create strong, accurate, and complex metal products, making this process ideal for aerospace, automotive, and medical applications.

• Titanium is lightweight and has excellent mechanical characteristics. It is strong, hard and highly resistant to heat, oxidation, and acid.

• Stainless steel has high strength, high ductility, and is resistant to corrosion.

• Aluminum is a lightweight, durable, strong, and has good thermal properties.

• Tool steel is a hard, scratch-resistant material that you can use to print end-use tools and other high-strength parts..

• Nickel alloys have high tensile, creep and rupture strength and are heat and corrosion resistant.

Compared to plastic 3D printing technologies, metal 3D printing is substantially more costly and complex, limiting its accessibility to most businesses.

Alternatively, SLA 3D printing is well-suited for casting workflows that produce metal parts at a lower cost, with greater design freedom, and in less time than traditional methods.  

Another alternative is electroplating SLA parts, which involves coating a plastic material in a layer of metal via electrolysis. This combines some of the best qualities of metal—strength, electrical conductivity, and resistance to corrosion and abrasion—with the specific properties of the primary (usually plastic) material.

Plastic 3D printing is well-suited to create patterns that can be cast to produce metal parts.

With all these materials and 3D printing options available, how can you make the right selection?

Here’s our three-step framework to choose the right 3D printing material for your application.

Plastics used for 3D printing have different chemical, optical, mechanical, and thermal characteristics that determine how the 3D printed parts will perform. As the intended use approaches real-world usage, performance requirements increase accordingly.

Requirement	Description	Recommendation
Low performance	For form and fit prototyping, conceptual modeling, and research and development, printed parts only need to meet low technical performance requirements. Example: A form prototype of a soup ladle for ergonomic testing. No functional performance requirements needed besides surface finish.	FDM: PLA SLA: Standard Resins, Clear Resin (transparent part), Draft Resin (fast printing)
Moderate performance	For validation or pre-production uses, printed parts must behave as closely to final production parts as possible for functional testing but do not have strict lifetime requirements. Example: A housing for electronic components to protect against sudden impact. Performance requirements include ability to absorb impact, housing needs to snap together and hold its shape.	FDM: ABS SLA: Engineering Resins SLS: Nylon 11, Nylon 12, TPU
High performance	For end-use parts, final 3D printed production parts must stand up to significant wear for a specific time period, whether that’s one day, one week, or several years. Example: Shoe outsoles. Performance requirements include strict lifetime testing with cyclic loading and unloading, color fastness over periods of years, amongst others like tear resistance.	FDM: Composites SLA: Engineering, Medical, Dental, or Jewelry Resins SLS: Nylon 11, Nylon 12, TPU, nylon composites

Once you’ve identified the performance requirements for your product, the next step is translating them into material requirements—the properties of a material that will satisfy those performance needs. You’ll typically find these metrics on a material’s data sheet.

Requirement	Description	Recommendation
Tensile strength	Resistance of a material to breaking under tension. High tensile strength is important for structural, load bearing, mechanical, or statical parts.	FDM: PLA SLA: Clear Resin, Rigid Resins SLS: Nylon 12, nylon composites
Flexural modulus	Resistance of a material to bending under load. Good indicator for either the stiffness (high modulus) or the flexibility (low modulus) of a material.	FDM: PLA (high), ABS (medium) SLA: Rigid Resins (high), Tough and Durable Resins (medium), Flexible and Elastic Resins (low) SLS: nylon composites (high), Nylon 12 (medium)
Elongation	Resistance of a material to breaking when stretched. Helps you compare flexible materials based on how much they can stretch. Also indicates if a material will deform first, or break suddenly.	FDM: ABS (medium), TPU (high) SLA: Tough and Durable Resins (medium), Polyurethane Resins (medium), Flexible and Elastic Resins (high) SLS: Nylon 12 (medium), Nylon 11 (medium), TPU (high)
Impact strength	Ability of a material to absorb shock and impact energy without breaking. Indicates toughness and durability, helps you figure out how easily a material will break when dropped on the ground or crashed into another object.	FDM: ABS, Nylon SLA: Tough 2000 Resin, Tough 1500 Resin, Grey Pro Resin, Durable Resin, Polyurethane Resins SLS: Nylon 12, Nylon 11, nylon composites
Heat deflection temperature	Temperature at which a sample deforms under a specified load. Indicates if a material is suitable for high temperature applications.	SLA: High Temp Resin, Rigid Resins SLS: Nylon 12, Nylon 11, nylon composites
Hardness (durometer)	Resistance of a material to surface deformation. Helps you identify the right “softness” for soft plastics, like rubber and elastomers for certain applications.	FDM: TPU SLA: Flexible Resin, Elastic Resin SLS: TPU
Tear strength	Resistance of a material to growth of cuts under tension. Important to assess the durability and the resistance to tearing of soft plastics and flexible materials, such as rubber.	FDM: TPU SLA: Flexible Resin, Elastic Resin, Durable Resin SLS: Nylon 11, TPU
Creep	Creep is the tendency of a material to deform permanently under the influence of constant stress: tensile, compressive, shear, or flexural. Low creep indicates longevity for hard plastics and is crucial for structural parts.	FDM: ABS SLA: Polyurethane Resins, Rigid Resins SLS: Nylon 12, Nylon 11, nylon composites
Compression set	Permanent deformation after material has been compressed. Important for soft plastics and elastic applications, tells you if a material will return to its original shape after the load is removed.	FDM: TPU SLA: Flexible Resin, Elastic Resin SLS: TPU

Once you translate performance requirements to material requirements, you’ll most likely end up with a single material or a smaller group of materials that could be suitable for your application. 

If there are multiple materials that fulfil your basic requirements, you can then look at a wider range of desired characteristics and consider the pros, cons, and trade-offs of the given materials and processes to make the final choice.

3D Printing Materials Guide: Plastics

Published on June 8, 2020 by Alexandrea P.

A plastic is a material made of synthetic or semi-synthetic compounds that has the property of being malleable (capable of changing its shape). Most plastics on the market are completely synthetic (most commonly derived from petrochemicals). However, given the growing environmental concern, plastics derived from renewable materials such as Polylactic Acid (PLA) are also popular on the market. Due to their low cost, ease of manufacture, versatility and water resistance, plastics are used in a multitude of products and sectors. In the AM sector, 3D printing plastics are also very popular.

In the following guide, we will take a look at the most common 3D printing plastics. As you may know, the most popular and affordable 3D printing process, FDM, produces parts through the extrusion of plastic filaments. However, the precision on FDM machines is not the same as other AM processes such as SLS or SLA. Plastics are often used with this technology to create prototypes. Therefore, for industrial and end-use parts, manufacturers might decide to opt for SLS (using plastic powders) or SLA (using plastic resins) technologies that offer more accuracy and part quality. Two other technologies that can print with plastics are Material Jetting and Multi Jet Fusion.

What plastics can be used in additive manufacturing? In filament or powder form, the plastic should melt to form the object you are printing layer by layer. In resin form, it should solidify to form the object. Each plastic will require different 3D printing parameters during the building process, and will give parts varying properties.

ABS

ABS filament is the most commonly used 3D printing plastics. It is used in the bodywork of cars, appliances, and mobile phone cases. It is a thermoplastic which contains a base of elastomers based on polybutadiene, making it more flexible, and resistant to shocks. ABS can also be found in powder form for powder bed processes such as SLS, and liquid form for SLA and PolyJet technologies.

ABS is used in 3D printing when heated between 230ºC and 260ºC. It is a tough material, able to easily withstand temperatures of -20ºC to 80ºC. In addition to its high strength, it is a reusable material and can be welded with chemical processes. However, ABS is not biodegradable and shrinks in contact with air, so the printing platform must be heated to prevent warping. Moreover, it is recommended to use a closed chamber 3D printer to limit particle emissions when printing with ABS. Learn more about ABS in our dedicated guide.

PLA

Known as polylactic acid, or PLA, this material has the benefit of being biodegradable, unlike ABS. PLA is manufactured using renewable raw materials such as corn starch. PLA is one of the easiest materials to print, though it does have a tendency to shrink slightly after 3D printing. You don’t require a heated platform when printing in PLA, unlike with ABS. PLA also prints at a lower temperature than ABS, between 190ºC to 230ºC.

PLA is a more difficult material to manipulate due to its high cooling and solidification speed. It is also important to mention that models can deteriorate when in contact with water. However, the material is consistent, simple to use, and comes in a wide variety of colors, making it suitable for FDM 3D printing. Learn more about PLA in our dedicated guide.

ASA

ASA is a material that has similar properties to ABS, but has a greater resistance to UV rays. As with ABS, it is advised to print the material with a heated bed platform to prevent warping. When printing with ASA, similar print settings are used to ABS, but extra care must be taken to print with a closed chamber due to styrene emissions.

PET

Polyethylene terephthalate, or PET, is commonly seen in disposable plastic bottles. PET is the ideal filament for any pieces intended for contact with food. Moreover, the material is fairly rigid and has good chemical resistance. To obtain the best results when printing with PET, print between 75 – 90ºC. PET is commonly marketed as a translucent filament, with variants such as PETG, PETE, and PETT also sold. Advantages of PET include that the material doesn’t release any odours when printing, and is 100% recyclable.

PETG

PETG, or glycolized polyester, is a thermoplastic widely used in the additive manufacturing market, combining both the simplicity of PLA 3D printing and the strength of ABS. It is an amorphous plastic, which can be 100% recycled. It has the same chemical composition as polyethylene terephthalate, better known by its acronym PET. Glycol has been added to reduce its brittleness and therefore its fragility. Learn more about PETG in our dedicated guide.

Polycarbonate (PC)

Polycarbonate (PC) is a high strength material designed for engineering applications. The material has good temperature resistance, able to resist any physical deformation up to around 150ºC. However, PC is prone to absorbing moisture from the air, which can affect performance and printing resistance. Therefore, PC has to be stored in airtight containers. PC is highly valued by the AM industry for its strength and transparency. It has a much lower density than glass, making it particularly interesting for designing optical parts, protective screens or decorative objects. Learn more about PC in our dedicated guide.

High Performance Polymers (PEEK, PEKK, ULTEM)

The evolution of 3D printing technologies has led to extensive research work on printing materials, enabling the development of a whole range of high-performance filaments with mechanical characteristics similar to those of metals. There are several types of high-performance 3D printing plastics such as PEEK, PEKK or ULTEM – they are distinguished by family such as polyaryletherketones (PAEK) or polyetherimides (PEI). These filaments have a very high mechanical and thermal resistance, are very strong and at the same time much lighter than some metals. These properties make them very attractive in the aerospace, automotive and medical sectors.

Due to their characteristics, high performance polymers cannot be printed on all FDM machines on the market. Indeed, the 3D printer must have a heating plate capable of reaching at least 230°C, an extrusion at 350°C and a closed chamber. Today, about 65% of these materials are printed with FDM technology, but they are also found in powder form, compatible with SLS technology. Learn more in our dedicated guides on PEEK and PEKK.

Polypropylene (PP)

Polypropylene is another thermoplastic widely used in the automotive sector, professional textiles sector, and in the manufacturing of hundreds of everyday objects. PP is known for its resistance to abrasion and its ability to absorb shocks, as well as relative rigidity and flexibility. However, drawbacks of the material include its low temperature resistance, and sensitivity to UV rays which can cause it to expand. Due to this, several manufacturers have developed alternative types of PP, simili-propilenos, that are stronger both physically and mechanically.

Nylon

Objects made from polyamides (nylon) are usually created from a fine, white, granular powder with SLS technology. There are however some variants of the material such as nylon that are also available in filaments used in fused deposition modeling (FDM). Due to its biocompatibility, polyamides can be used to create parts that come into contact with food (except foods that contain alcohol).

Constituted of semi crystalline structures, polyamides have a good balance of chemical and mechanical characteristics that offer good stability, rigidity, flexibility, and shock resistance. These advantages mean that the material has many applications across sectors and offers a high level of detail. Due to its high quality, polyamides are used in the manufacture of gears, parts for the aerospace market, automotive market, robotics, medical prostheses, and injection molds. You can learn more in our dedicated guide on Nylon.

Composites

Composites are extremely beneficial when making lightweight yet strong parts. The fibers add strength to a part without adding weight, which is why we also refer to composites as fiber reinforced materials. There are two types of reinforcements, short fiber or continuous fiber. In the first case, chopped fibers, which consist of segments less than a millimeter in length, are mixed into traditional 3D printing plastics to increase the stiffness and to a lesser extent the strength of components. Chopped fibers can be mixed with thermoplastics such as nylon, ABS or PLA.

Alternatively, the fibers can be added to the thermoplastics continuously to arrive at a stronger part. The main fiber used in the 3D printing sector is carbon fiber, but there are also other fibers such as glass fiber or Kevlar. You can find more information in our dedicated guide.

Hybrid Materials

There are a variety of hybrid materials that mix base plastics with powders to give them a new color, finish or additional material properties. Often based on PLA, these materials are usually made of 70% PLA and 30% hybrid material. For example, wood-based filaments ranging from bamboo, cork, wood dust, and more are available. These wood-based materials mixed with PLA give the hybrid filament a more organic texture. Additionally, some hybrid materials incorporate metal powders to work with FDM-based technologies, to give parts a metal finish. They can be based on copper, bronze, silver, and more.

Alumide

Alumide plastic objects are manufactured from a combination of polyamides and aluminium powder using the SLS process. The material has a large, slightly porous surface and a gritty, grainy appearance offering great strength and good temperature resistance (up to 172°C). However, some post-processing treatments are necessary, such as grinding, sanding, coating, or milling.

Alumide is used for complex models, design pieces, or for small series production of functional models that need high rigidity and an appearance similar to aluminium. This technique involves few geometric limits.

Soluble Materials

Soluble materials are materials printed with the intention of being dissolved in a future stage of the manufacturing process. The two most common soluble filament materials are HIPS (High Impact Polystyrene) and PVA (Polyvinyl Acetate). HIPS is associated with ABS, and can be dissolved with limonene, whereas PVA is associated with PLA and can be dissolved using just water.

There are also BVOH filaments which are becoming increasingly popular, especially in dual extruder printers. This is because the material is soluble in water, and according to experts has a higher solubility than PVA.

Flexible Materials

A newer type of filament, and one of the most successful, are flexible filaments. They are similar to PLA, but usually made out of TPE or TPU. The advantage of using these filaments for 3D printing is they allow for the creation of deformable objects, widely used in the fashion industry. Generally, these flexible filaments have the same printing characteristics as PLA, though they come in a variety of ranges based on their stiffness. It is worth finding out which type of extruder is best suited to the material to avoid jams when 3D printing.

Flexible materials are widely used in fashion and design

Resins (for photopolymerization-based 3D printing)

3D printing technologies based on photopolymerization use UV-sensitive resins to create objects layer by layer. In other words, they use a light source such as a laser or LCD screen to solidify a liquid photopolymer. Technologies include SLA, DLP, and even Material Jetting (PolyJet). Creating parts using resins results in high detail and smooth surface objects, nevertheless, the color range is still quite limited using this process. What differentiates resins from FDM filaments is that it is impossible to mix resins to obtain different results quite easily.

Standard resin has properties similar to ABS: the surface finish of the part will be good given the photopolymerization process, however mechanical properties will be moderate. More advanced resins do exist for technical applications such as in dentistry (also need to be biocompatible), or engineering. Additionally, flexible resins that offer greater flexibility and deformation can be used to make jewelry. Over the years, manufacturers have expanded their range of liquid photopolymers to answer manufacturing needs from various sectors. Therefore, you should be able to find resins that have high-temperature resistance, can withstand large impacts, or that have high elongation properties.

  Every year 3D printing becomes more popular and accessible. Previously, a 3D printer was more like a complex CNC machine, but now manufacturers are meeting users. Simplified and automated settings that many beginners drove into a stupor. Despite this, it can be difficult for a novice user to understand the variety of constantly appearing plastics for a 3D printer.

  The choice of plastic for a 3D printer is very important, especially when the goal is to print a functional model with certain properties. It will be a shame if the printed gear breaks almost immediately, or the decorative model quickly loses its beauty.

  It is important to understand whether the printer will be able to work with the selected plastic. Some materials (most often engineering) require certain conditions for successful printing.

  First, decide which model you want to print. What properties should it have? Does the model need to be durable? Or is it a master model for further replication, in which the quality of the surface is important?

  90% of 3D printers use 1. 75 diameter filament. 3mm diameter is rare, but it is better to check in advance which size is used in your printer.

  PLA

  PLA (Polylactide) is the most popular and affordable 3D printer plastic. PLA is made from sugar cane, corn, or other natural raw materials. Therefore, it is considered a non-toxic, biodegradable material.

  Extruder temperature - 190-220 degrees. Table heating is not needed, but if the printer's table has a "heater" for better adhesion, you can heat it up to 50-60 degrees. PLA is very easy to work with. The only requirement is to blow the model. There is practically no shrinkage in this material. When printed, it is practically odorless, and if it smells, it smells like burnt caramel.

  Pros:

  • Does not shrink. This makes it easy to build prefabricated or huge models without changing dimensions.

  • There are no specific requirements for a 3D printer. Any working 3D printer will do. PLA doesn't need a heated table or a closed case.

  • Non-toxic. Due to this, during printing it does not smell or has a barely perceptible aroma of burnt caramel.

  • Diverse color palette.

  Cons:

  • PLA is poorly sanded and machined.

  • It begins to deform already with a slight heating (about 50 degrees).

  • Fragility. Compared to other materials, PLA is very brittle and breaks easily.

  • Decomposes under the influence of ultraviolet radiation. Of course, it will not fall apart into dust, but it can become more brittle and fade.

  PLA is perfect for making dimensional or composite models. For example, decorative interior items, prototyping, electronics cases, etc.

  Recently, PLA+ has appeared on the market. It may differ from conventional PLA in improved performance. For example, more durable, with improved layer adhesion.

  ABS

  ABS (acrylonitrile butadiene styrene) is the second most popular plastic for 3D printing due to its properties, availability and low price.

  Extruder temperature - 220-240 degrees. The temperature of the table is 80-100 degrees. For printing, a heated table is required at the printer. It is desirable to have a closed chamber, because ABS "does not like" drafts. Due to a sharp temperature drop, it can “unstick” from the table or crack in layers. ABS can smell bad when printing, so it is recommended to use the printer with a closed chamber and filters, or print in a well-ventilated area.

  Pros:

  • Good strength characteristics allow the production of functional prototypes from ABS.

  • Simple mechanical and chemical processing. ABS is easy to sand and drill, and with an acetone bath you can achieve a perfectly smooth surface.

  • It is currently the most inexpensive type of plastic for 3D printing.

  • Large selection of colors and shades.

  Cons:

  • High shrinkage. Because of this, it can be problematic to manufacture overall products.

  • Printing requires a heated bed and a closed chamber. Without this, the ABS may peel off the table or crack in layers.

  • During the printing process, ABS can smell bad. Therefore, it is recommended that you print in a ventilated area or use the printer with a sealed chamber and filter.

  ABS is an engineering plastic. It is suitable for the manufacture of simple functional products.

  ABS+ differs from conventional ABS in improved strength characteristics (elasticity, rigidity, hardness), less shrinkage and sometimes resistance to certain oils and solvents (eg gasoline).

  
  

  HIPS

  HIPS (high impact polystyrene) - originally conceived as a soluble support plastic for materials with high printing temperatures. For example for ABS or Nylon.

  The extruder temperature is 230-260 degrees. The temperature of the table is 80-100 degrees. It is desirable to have a closed camera for a 3D printer.

  Pros:

  • Less shrinkage than ABS.

  • Ease of machining.

  • The matte surface looks very advantageous on decorative products.

  • Food contact allowed (but be sure to check with a specific manufacturer for certificates)

  Cons:

  • For printing, you need a printer with a heated table and a closed chamber.

  • More flexible and less durable than ABS. Because of this, it will not be possible to produce functional products.

  • Small palette of colors.

  Most often, HIPS is used for its intended purpose for printing on 2x extruder printers as a support for ABS. It dissolves perfectly (though not very quickly) in limonel.

  Sometimes HIPS is used as an independent material. Products from it are not very durable, but this plastic is loved for easy post-processing. HIPS can be used for models that will subsequently come into contact with food (not hot).

  Using HIPS as a Soluble Support

  PVA

  PVA (polyvinyl alcohol) is a material that was developed as a water-soluble support for PLA.

  Extruder temperature - 190-210. Table heating is not required. PVA is a slightly "capricious" material, it is not recommended to overheat it and print at high speeds.

  PVA is very hygroscopic and dissolves in plain water. Therefore, it is only used as a support for PLA or other plastics with print temperatures close to PVA.

  PETG

  PETG (polyethylene terephthalate) combines the best properties of PLA and ABS. It is easy to work with, it has a low percentage of shrinkage and excellent sintering of the layers.

  Extruder temperature - 220-240 degrees. Table temperature - 80-100 degrees. During the printing process, the model must be well blown.

  Pros:

  • Excellent sinterability of layers.

  • PETG is very strong and wear resistant. Good impact resistance.

  • Virtually no smell when printing.

  • Non-toxic.

  • Little shrinkage.

  Cons:

  PETG is perfect for printing functional models. Due to its low shrinkage, it is often used to make large or composite models. Due to its low toxicity, PETG is often used for products that will come into contact with food.

  SBS

  It is a highly transparent material. At the same time, it is durable and resilient. SBS is a low toxicity plastic. It can be used to print food contact models.

  Extruder temperature - 230 -260 degrees. Table temperature - 60-100 degrees. You can print without the closed case on the printer.

  Pros:

  • slight shrinkage

  • Transparency. After treatment with solvent, limonel or dichloromethane, beautiful transparent products with an almost smooth surface can be obtained.

  • Easily processed mechanically or chemically.

  • Allowed contact with food.

  Cons:

  SBS is excellent for translucent vases, children's toys and food containers. Or functional things that require transparency, such as custom turn signals for a motorcycle or car, lamps or bottle prototypes.

  Vases are perfectly printed with a thick nozzle (0.7-0.8) in one pass (printing in 1 wall or spiral printing in a slicer).

  Nylon

  Nylon (polyamide) is considered the most durable material available for home 3D printing. In addition to good abrasion resistance and strength, it has a high slip coefficient.

  Extruder temperature - 240-260 degrees. The temperature of the table is 80-100 degrees. Nylon is a very capricious and hygroscopic material - it is recommended to dry the coil with plastic before use. For printing, you need a printer with a heated table and a closed chamber, without this it will be difficult to print something larger than a small gear.

  Pros:

  • High strength and wear resistance.

  • High slip factor.

  • Heat resistance compared to other 3D printing plastics.

  • High resistance to many solvents.

  • Good for mechanical processing. Perfectly polished and drilled.

  Cons:

  Nylon is perfect for making wear-resistant parts - gears, functional models, etc. Sometimes nylon is used to print bushings.

  Soft plastics

  FLEX (TPU, TPE, TPC) is a material similar to silicone or rubber. It is flexible and elastic, but at the same time tear-resistant. For example, TPE is a rubbery plastic, while TPU is more rigid.

  FLEX are printed at a temperature of 200-240 (depending on the material). A heated table is not required. On printers with direct material feed (feed mechanism on the print head), there are usually no problems with printing. On a bowden feeder (the feed mechanism is located on the body), printing with very soft plastics can be difficult. Usually it is necessary to additionally adjust the clamping of the bar. The main nuance is the very low print speeds - 20-40mm.

  Pros:

  Cons:

  Depending on the type of FLEXa, the models can be flexible or rubber-like. This material, depending on its softness, can be used to print gaskets, insoles, belts, tracks or other models that require flexibility or softness.

  Decorative plastics

  Decorative plastics are PLA plastics with various fillers (wood or metal shavings). Or with dyes selected to imitate different materials. Since the base of the plastic is PLA, it is very easy to print.

  Extruder temperature - 200-220 degrees (depending on the manufacturer). A heated table is not required.

  Pros:

  Cons:

  • Some fillers (eg clay) are abrasive. For such plastics, the standard brass nozzle cannot be used. Will have to buy a harder steel nozzle.

  • Some decorative plastics can clog the small nozzle (0.4 or less). For them, you need to use a “thicker” nozzle.

  Depending on the filler, different material properties are obtained. Plastics that use only dye do not require additional processing. Materials with "fillers" may sometimes require additional post-processing.

  Plastics with metal fillers after printing must be processed with a metal brush. Then the Metal content will show through and the model will resemble a metal casting.

  Plastics with metallic powder
  

  These plastics are often used for printing key chains, decorative models and interior details.

  If the plastic has a high content of wood dust, then it is recommended to use a larger nozzle diameter (0.5 or more), a smaller nozzle can quickly become clogged during printing.

  Engineering plastics

  These are nylon-based plastics with fillers that improve strength, heat-resistant and other characteristics, help to achieve less shrinkage of the material. For example - carbon fiber, carbon fiber or fiberglass.

  Extruder temperature - 240-300 degrees (depending on the manufacturer). Table temperature - 90-110 degrees. Since plastics are based on nylon, the requirements for printing are similar. This is a heated table and a closed printer case.

  Pros:

  • Hardness and strength.

  • Low flammability or non-combustibility.

  • High precision due to low shrinkage.

  Cons:

  
  

  3D printers use brass nozzles, some plastics can quickly “waste” it during printing. For such materials it is recommended to use steel nozzles.

  These are highly specialized plastics used for a specific task, depending on the filler. For example, functional parts that do not lose their shape when heated, are resistant to many solvents, etc.

  Totals

  This is of course not the whole list of materials for 3D printing. There are many highly specialized engineering and decorative plastics for specific tasks.

  Manufacturers are constantly trying to replenish the range of materials for 3D printing. Already familiar materials are improved for more comfortable printing. There are many interesting decorative plastics imitating different materials - ceramics, clay, wood, metals.

  And of course, the assortment of engineering plastics is constantly updated. Now there are many interesting materials for highly specialized tasks - for example, burnable plastic with a low ash content for subsequent casting in metal.

  Burnout plastic

  Before buying a coil, read the information on the website of the manufacturer or seller. There you can find some nuances of printing for a particular plastic. The manufacturer indicates the recommended temperature range on the box. Sometimes, for quality printing, it is recommended to print several tests to adjust the temperature settings, retract, etc.

  Try to store the started coil in silica gel bags. It is recommended to additionally dry high-temperature plastics before printing to remove excess moisture.

  Frequently Asked Questions

  Which technology should I choose: Fusion Fusion (FGF) or Polymer Filament Filament (FFF/FDM)?

  What are the kinematics and mechanics of the Discovery equipment?

  In this respect, all Discovery equipment differs from budget additive solutions. The products are based on the kinematic diagram of a CNC machine. Gears, pulleys, lead screws, no belts. HIVIN rail guides are used. The entire structure is made with European quality from advanced products in the machine tool industry.

  What consumables can be used with Discovery products?

  Any material (other than PEEK and PEKK) sold in bars or pellets. First of all, thanks to the heating of the table to 175 ° C and vacuum fixation, as well as due to the installed nozzles made of hardened steel.

  How is such a large print platform heated?

  A matrix of separate equidistant heaters is built into the platform from the bottom side; these modules provide uniform heating of the surface of the printing platform. The maximum recorded temperature difference over the entire area is 3°C.

  How to speed up printing on such large dimensions?

  There is a special method for properly emptying the internal volume, which you can learn more about from our technical experts. This procedure will have very little effect on the strength and elasticity of the print object, but will still reduce the time by up to 60%.
  It is important to consider that with a large range of large-sized products, it is better to consider Super Discovery 3D Printer or Super Discovery 3D Printer Workstation with a capacity of up to 11 kg / h (depending on the material used).

  Is it possible to upgrade this equipment for a specific enterprise?

  Yes. Most of the Discovery machines can be upgraded for a specific production project. This is possible, since the equipment was designed for the tasks of Production 4.0, and our specialists will help to integrate it correctly.

  What is the warranty for this equipment?

  24 months, which is 1.5 - 2 times more than analogues from Europe, Russia and China. Permanent customer support is provided directly by the vendor or iQB Technologies specialists.

  How to get a high quality product so that it can be handed over as a final product?

  3D printing is basically a high quality preform process.
