Comparison & List of 3D Materials

Below you will find information on 16 different types of 3D printing materials. Chances are that even if you are a 3D printing expert you will learn something new in this guide. You can try magnetic, glow-in-the-dark, or even conductive filaments.

Before we get into 3D materials, it helps to look at the 2D printing process we’ve all come to know. All printers need some kind of substance to print with. For 2D printing, we’re most familiar with inkjet printers that use liquid inks. These machines extrude ink through microscopic nozzles onto papers. 2D laser printers also print to papers. Instead of ink, they use a toner cartridge filled with a special type of fine powder and a heated fuser. 2D printing produces two-dimensional, flat, results that have width and height but no depth (thickness). Pigment-based and solid inks are other materials used for printing in 2D. Today, we can also print in 3D with special machines and printing materials.

2D Printing Compared to 3D Printing

There’s a distinct difference between the two technologies. 3D printers build real-world objects, whereas 2D printers publish text and graphics on papers. Before either machine can print, they need computer-generated, digital files. These files tell the machines what to produce and how to print it based on user preferences. Both types of printers use inks, or materials, to carry out the job. That’s pretty much where the familiarities end. 2D printers can’t build layers to produce real-world objects.

One of the most important parts of 3D printing is to use the right kind of material for the job in hand. In this guide we look at the range of 3D materials, also called filaments, a 3D printer uses, starting with the most popular. We’ll also cover their uses along with pros and cons for each type. This will help you to make better informed decisions when buying your 3D printer filaments. Before you print anything in 3D, there are a few basic questions you should ask yourself, the main ones include:

• Strength: How strong does your printed part have to be?
• Flexibility: How flexible does your part need to be?
• Accuracy: How important is precision to your 3D part?
• Special conditions: Any other conditions that apply to your 3D model

These are the 3D printing materials that are covered in this guide:

1. ABS Filament
2. PLA Filament
3. PET Filament
4. PETT Filament
5. Nylon Filament
6. PVA Filament
7. Sandstone Filament
8. Wood Filament
9. Metal Filament
10. HIPS Filament
11. Magnetic Iron Filament
12. Conductive Filament
13. Carbon Fiber Filament
14. TPE Filament

3D Filament Defined

3D filaments are special types of plastics called thermoplastics. Once heated to the right temperature, thermoplastics become flexible. It’s this pliability that allows the printer to sculpt the filament to create your shapes before it cools down. In 2017, the two common types of 3D filaments are:

1. ABS (Acrylonitrile Butadiene Styrene)
2. PLA (Polylactic Acid)

These are not the only 3D filaments available. We’ll look at other types later in the guide. For now we’ll focus on ABS and PLA, and see what makes them such popular choices. For each material we’ll start with a short introduction followed by the average price, print temperature, and applications. At the end of each 3D material we’ll list its pros and cons. Also worth noting is that not all 3D printers can utilize both ABS and PLA. Some can, but not all, so you need to know your 3D printer capabilities as well as the abilities of the 3D filaments.

1. ABS 3D Filament

PRICE STARTING FROM: $20 for 1. 75 mm, 1kg spool

ABS is popular for good reasons. It’s tough, and has impact-resistant properties. It’s this strength and moderate flexibility that makes it such a great choice for printing in 3D. It’s also easy to extrude from the printer’s nozzles, which makes it an easy material to work with.

Don’t Miss: Best ABS Filaments.

ABS print temperature range: 210°C – 250°C (high)

Applications

ABS is a great choice for printing plastic automotive parts, moving parts, musical instruments, kitchen appliances, electronic housings, and various toys, like LEGO. It has other applications too, aside from 3D printing. For example, traditional manufacturers use ABS to make plastic wrap, water bottles, and cups, to name a few uses. Despite its popularity for 3D printing, ABS is not the best filament for most home users. This is because it has a high melting point that needs to print on a heated surface, or bed. A heated printer bed is not something a lot of budget-range 3D printers come equipped with. Printing with ABS also produces unpleasant fumes that can irritate some people. Needless to say, good ventilation is essential. These things combined make ABS a material favored more by professionals than amateur users.

Check Price of ABS Filament on Amazon

The Pros

• A durable, strong 3D filament
• Quite flexible and lightweight
• Cheapest thermoplastic available at the time of writing
• Most favored material among professional 3D printers and keen armatures

The Cons

• ABS is petroleum-based, making it a non-biodegradable material
• Needs a high temperature to reach its melting point
• Creates unpleasant fumes, most notable in poorly ventilated spaces

2. PLA 3D Filament

PRICE STARTING FROM: $20 for 1.75 mm, 1kg spool

PLA (Poly Lactic Acid) is popular for amateurs and professionals alike. It’s a special type of thermoplastic made from organic materials, namely cornstarch and sugarcane. The main benefits of PLA are that it’s safer and easier to use, and with no toxic fumes to worry about. Some users even find the sweet smell of the sugar-based filament pleasant. Compared to ABS, PLA produces 3D parts which are more aesthetically pleasing. This finish is thanks to its unique sheen and smooth appearance.

You might think it sounds like the perfect solution, but there are some drawbacks. For one, the melting point of PLA is much lower than ABS, and that makes it weaker. This matters if you’re printing moving parts or exposing the parts to high temperatures. Both of these things can result in the 3D objects, cracking, warping or even melting. If none of the above applies to you and your 3D projects, then PLA should be your filament of choice. It will award you with superior print details and is also less prone to printing errors during the build process.

PLA print temperature range: 180°C – 230°C (low)

Applications

PLA has wide-ranging uses. At the professional level, PLA filament uses include medical suturing (stitching). We can also see PLA used for various surgical implants, including surgically implanted pins, rods, screws, and mesh. The applications work thanks to the material’s degradable properties. All the aforementioned 3D printed parts break down in the human body. They can take anywhere between six months to two years, depending on the part and its purpose. At the amateur level, PLA filament is great for producing a whole range of consumer items. Other benefits of PLA are that it prints faster than ABS, and there’s no need for a heated printer bed. The end products are a decent strength, durable, and offer some degree of impact resistance. Aside from 3D printing, other products that use PLA include food packaging, disposable tableware, and diapers, as a few examples.

Choosing the Right 3D Printer Filament

This guide gives you a good insight into the different 3D printer filaments on the market. There are others, but the ones listed here are the most widespread, easy-to-source materials at the time of writing. Before you choose the right filament for your next job, you need to check a few boxes. For example, as well as knowing what you intend to build, you also need to understand your printer’s capabilities. Not all 3D printers are able of printing in all 3D materials.

You also need to prepare for trial and error if you plan to experiment with some of the more tricky filaments. Another consideration is the diameter of the filament, either 1.75mm or 3mm. If you’re unsure, always opt for 1.75mm as it’s easier to work with. 3D filament storage is another crucial area to think about. These plastics can absorb moisture from the air which can mess with the printing process. When not in use, a good way to store your 3D filament is to use vacuum bags that have a double zipper line for better, airtight sealing.

And finally, don’t allow the cheapest of the cheap filaments tempt you as they could prove to be a false economy. Seriously, low-cost, low-grade 3D printing filaments are more likely to contain chemical impurities. These impurities can result in unsatisfactory printed parts and clogged-up printer nozzles.

It might all sound like a lot absorb, but none of this takes long to pick once you start to dabble.

Warning; 3D printers should never be left unattended. They can pose a firesafety hazard.

What is the best plastic for 3D printing? Let's figure it out together!

Plastic for 3D printing

After purchasing your own FDM 3D printer, as well as in the course of choosing it, it becomes necessary to choose the right plastic for 3D printing. But how to do this if you are new to 3D printing and have little to no understanding of this issue? Plastic for printing on a 3D printer is in most cases the main component of successful product reproduction. Therefore, we will not save on knowledge, and will tell you how to choose the best plastic for 3D printing.

Types of plastic for a 3D printer

First of all, we need to consider the types of plastic for a 3D printer. Plastic for 3D printing, or filament, is produced in the form of a thin thread with a diameter of 1.75 mm and 3 mm. Most often, filaments with a thickness of 1.75 mm are used in the basic configuration, but some manufacturers of 3D printers provide the ability to install a 3 mm plastic feed system. Plastic for 3D printing has many varieties, among which the most common are ABS and PLA plastic.

Plastic for 3D printing: varieties

By popularity in the Ukrainian market, the following types of plastic for 3D printing can be distinguished:

• PLA (PLA) or polylactide. Organic and short lived. Suitable for 3D printing of decorative products, but not able to withstand high mechanical loads;
• ABS (ABS) or acrylonitrile butadiene styrene. It has a long life and excellent mechanical properties. Heat-resistant and used for industrial purposes. Shrinks on cooling. It is recommended to print in ventilated areas;
• PVA (PVA) or polyvinyl alcohol. A water-soluble material that is used as a support;
• Nylone (Nylon). An alternative to ABS plastic, suitable for many engineering structures. When printing with nylon, it is recommended to ventilate the room;
• HIPS (High Impact Polystyrene). In terms of physical properties, it is a cross between PLA and ABS. May also emit toxic fumes when printed.

Other questions and answers about 3D printers and 3D printing:

What is the best plastic for a 3D printer?

In fact, there are many more types of plastic for 3D printing. This can include flexible, fluorescent and luminescent filament, wood and metallized materials. But in practice, such consumables are rarely used and are needed for narrowly specific purposes. Metallized plastics are interesting in their own right, but they are at the initial stage of development and are inferior in performance to ordinary reinforced materials. “And what plastic is best for a 3D printer?” - you ask. You should choose based on specific goals. If you intend to print decorative elements that will not be subject to payload, you can look at PLA plastic. If your goal is to print gears, structural parts and other things, look at reinforced materials for 3D printing.

What plastic to print with?

Please note that not every printer supports the full range of 3D printing materials. Before buying a specific filament, check the specifications of your own device to avoid wasting money. The rest is up to you and your imagination. A huge range of colors and shades of plastic is available for sale, matte and glossy, semi- and fully transparent materials. Such a variety will allow you to make almost any product to your taste.

• • PLA
  ABS
  • HIPS
  PVA Nylon 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).

  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.

  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.
