Main types of metal 3D printing technologies
The four main types of 3D metal printing technologies are:
- Metal Powder Bed Fusion 3D printing (SLS, SLM, DMP)
- Directed Energy Deposition (DED)
- Metal filament extrusion (FFF, FDM)
- Material Jetting and Binder Jetting
There are also some resin-based metal 3D printers, and metal sheet lamination 3D printers, but they are harder to come by.
It is not uncommon to see different acronyms and names for similar technologies. Each brand markets their own, proprietary methods. Some metal 3D printer companies even use a mix of different technologies.
A breakdown of the metal 3D printer market by technology types. Source: Aniwaa database (2019)Here we provide a deeper look into each 3D metal printer from our list. They are grouped together according to their main 3D printing technology type (powder bed fusion, material/binder jetting, extrusion, and DED).
Extrusion-based metal 3D printer selection (FFF, FDM)
Extrusion consists of heating the material (filament) and pushing it through a nozzle. In the metal 3D printing case, the filament is generally made up of metal particles mixed into a binding agent.
After the part is 3D printed, the result is a raw object or part; it must go through several post-processing steps– such as debinding and sintering– to attain its final form.
Most extrusion-based metal 3D printing processes include these steps. The above illustration is sourced from Desktop Metal (Bound Metal Deposition™ process).Desktop Metal’s Studio is an office-friendly, end-to-end metal 3D printing system. Aside from the printer, the Studio line also includes a debinding machine and a furnace for sintering. Indeed, parts 3D printed with this Desktop Metal 3D printer are “green”.
The Studio printer, with its proprietary Bound Metal Deposition technology, uses filament that is filled with small, metal rods. During debinding, the binding material (wax and polymer binders) is dissolved thanks to a proprietary liquid substance. The part is left porous, and must go in the furnace for its particles to fuse and densify the part.

Canada-based Rapidia offers an interesting and unique way to 3D print metal. They use a water-based metal paste, which eliminates the need for chemical debinding. The water evaporates during the 3D printing process, so the part only needs to go through the furnace in order to completely solidify and attain its final form.
Confirmed, available paste types include several Stainless Steels, Inconel, and a few ceramics. Copper, Tungsten Chrome Carbide, Titanium, and various other metals are in development.
The ExOne Metal Designlab, designed in collaboration with Rapidia, works on the same basis.

Pros and cons of metal 3D additive manufacturing
Benefits of 3D printing metal parts
- On-demand production: Metal additive manufacturing offers more flexibility and control over the production line.
- Complex designs made possible: With 3D printing technology, it is possible to create highly detailed and intricate parts that would have to be broken down into several pieces with traditional methods.
- Waste reduction: Compared to CNC milling, for example, metal AM produces much less waste as it only consumes the material needed for a certain part. This is more true for extrusion-based methods than it is for powder-based methods, where it isn’t always possible to re-use 100% of unsintered or unbinded material.
- Lighter parts: Whereas metal parts are usually completely solid infill-wise with other methods, 3D printing allows parts to be more or less hollow without undermining their strength and resistance.
- Cost-effectiveness: All the above benefits of metal 3D printing can inherently reduce costs per part, although high metal 3D printer prices do represent a significant entry barrier. Reaching a positive return on investment can take a while depending on your throughput.
Limits of metal 3D printing
- Metal 3D printing prices: Metal AM systems are still quite expensive, as are metal powders and metal filaments. There are hidden costs, too (e.g. energy consumption, learning curve, etc.).
- Environmental constraints and safety precautions: Most metal 3D printers have a large footprint and require specific operating environments with controlled temperatures, hygrometry, and more.
- Post-processing: In many cases it is necessary for parts to be post-processed, whether it’s debinding and sintering or finishing touches for surface quality.
- Physical properties: It can be difficult to achieve the same physical properties that traditionally manufactured metal parts have. There are a number of factors (e.g. anisotropy) to take into account during the design process and file preparation before even trying to 3D print a certain part.

Additional costs to consider are the materials for metal 3D printing, which can cost a few hundred USD/kg, as well as costs linked to post-processing (tools, time, etc.).
Applications for metal AM systems
There are thousands of possibilities and use cases for metal 3D printing in a wide range of industries. A few industries have been incrementally using metal AM:
- Aerospace
- Automotive
- Medical
Whether it’s for tooling, replacement parts, or final products, many businesses can benefit from metal 3D printing.
However, metal additive manufacturing isn’t necessarily beneficial for every single metal part. Although some metal 3D printing systems have a relative capacity for serial production, it is generally cheaper to keep using traditional methods for simple parts.
For cases where complex geometries, rapid prototyping, and mass customization are required, metal AM is convenient and efficient.

Metal 3D printing FAQ
Is 3D printed metal strong?
Metal 3D printed parts can be as strong (or even stronger) as metal parts created with traditional manufacturing processes such as casting. The part’s strength will, however, depend on the metal AM method used and the conditions in which it is 3D printed.
When was 3D metal printing invented?
Metal 3D printing became possible in the 1990s with the development of Selective Laser Melting technology. However, 3D metal printing only started to gain traction and public interest from around 2010 onwards.
How does metal 3D printing work?
There are several ways to 3D print metal. Layers of metal filament can be deposited one after the other, producing a green part that must later go through debinding and sintering steps. It is also possible to fuse metal powder particles together with a laser, or with an inkjet printhead that deposits drops of binding material onto the powder.
How Much Does a Metal 3D Printer Cost?
Cost Driver #1: Material Cost
One of the most important metal 3D printer costs is that of the raw materials. Metals for 3D printing are often far more expensive than other forms of the same metal. This is due to special processing and purity requirements. In addition to the raw material itself, some metal 3D printers require inert gas which can add a surprising amount to the overall annual cost. There are 3 main groups of metal 3D printed raw materials as listed below.
- Powder
One of the biggest disadvantages of powder-based metal 3D printing (typically laser-based printers) is the cost of the raw material. In most cases, the process to turn metal into powder is expensive and energy-intensive. In addition to this, the powder needs to be highly pure which only adds to the overall cost. Metal powder can cost anywhere from $79/kg for 17-4PH steel to $738/kg for advanced titanium alloys like Nitinol.
- Metal Wire
3D printing technologies like DED (Directed Energy Deposition) have much lower material costs because their raw material comes in wire form. Metal wire is much cheaper to produce than powder. Essentially, the costs are comparable to spooled welding wire. However, it must be noted that DED printers do not produce good finishes and often need additional machining after printing is complete.
- Polymer Bound Metal
3D printers like the Desktop Metal Studio 2 and Markforged’s Metal X make use of a polymer-metal powder matrix that is supplied in spools. This process uses the same powder as MIM (Metal Injection Molding) processes and the quality and particle size tolerance is more lenient than is the case for laser-based systems. That all gives this technology the cheapest raw material cost. Desktop Metal claims the material cost per kg is 80% cheaper than normal laser-based powder printers.

Cost Driver #2: Design Software
Most metal 3D printing suppliers will provide software to prepare the part for printing. However, full-featured CAD software that can be used to design complex parts must be purchased at an additional cost. For instance, only specially designed software can properly simulate how loads will affect the performance of a complex, latticed 3D printed component. Normal analysis software cannot accurately simulate these special cases. The software also requires skilled operators who know how to use it effectively. These programs often operate on a subscription basis that may cost thousands of dollars per year to maintain for multiple users.
Cost Driver #3: Machine Cost
The metal 3D printer cost depends on a few factors. Each technology is best suited for certain applications, a fact which is evident in the varying machine costs. In general, metal 3D printers can be sourced for as little as a hundred thousand dollars but can also cost over a million dollars. Cheaper machines are best suited to low production volumes and don’t always produce optimally dense parts whereas higher-end machines can manufacture dense parts 24/7 with very little downtime. It must, however, be noted that the costs of advanced industrial-scale printers cannot be accurately determined due to factors such as shipping, geographic location, custom machine options, etc. Some common metal 3D printer costs are listed in the table below.
Name | Technology | Cost |
---|---|---|
Name Markforged - Metal X | Technology ADAM (Atomic Diffusion Additive Manufacturing) | Cost $99,500 |
Name Desktop Metal - Studio 2 | Technology Polymer/Metal Extrusion | Cost $110,000 |
Name Trumpf - TruPrint 1000 | Technology LMF (Laser Metal Fusion) | Cost $170,000 |
Name 3D Systems - DMP Flex 100 | Technology | Cost $245,000 |
Name Arcam - Spectra H | Technology EBM (Electron Beam Melting) | Cost $100,000 - $250,000 |
Name EOS - M 100 | Technology DMLS (Direct Metal Laser Sintering) | Cost $350,000 |
Name EP - M650 | Technology DMLS (Direct Metal Laser Sintering) | Cost $1,000,000 |
Name Desktop Metal - Production | Technology Single Pass Jetting | Cost $1,250,000 |
Name Lasertec - 6600 3D | Technology DED (Directed Energy Deposition) | Cost $3,000,000 |
Cost Driver #4: Post-Processing Cost
Metal 3D printing often requires varying degrees of post-processing. In some cases, the part needs to be sintered in a furnace, and in other cases, post-machining or polishing will be needed. All of these post-processes add to the overall metal 3D printer cost and need to be considered when choosing a metal 3D printer. Some typical post-processes are listed below.
FREE Binder Jetting Metal 3D Printing Design Guide
- Machine and Part Cleaning: In the case of powder-based printers, the unused powder must be collected and sifted before it can be reused. In addition to this, the part may need post-processing, especially if it has support structures to remove.
- Machining & Polishing: In some cases, accurate features that 3D printers can’t achieve must be machined into the part using subtractive techniques. And even if that’s not the case, metal 3D printed parts do not come off the machine with polished surfaces. If the part needs polishing, that will have to happen after the part is printed, thus adding to the overall metal 3D printer cost.
- Heat Treatment or Sintering: Some metal 3D printing processes generate internal stresses within the part. This happens when the heat of a laser or electron beam creates uneven cooling. These stresses can be removed through stress-relieving heat treatment processes. Other printing technologies involve polymer binders that must be burnt out of the part in a sintering furnace. These are energy-intensive processes and add to the metal 3D printer cost.
Which Metal 3D Printer Do I Need?
It can be difficult to decide which metal printer is ideal because the total metal 3D printer cost of ownership is hard to calculate. In addition to this, the cost of the part can in some cases be more expensive when compared to metal injection molding or CNC machining. In most cases, it may be easier to outsource the manufacture of these parts — at least in the beginning stages — to get an idea of their production cost. Another method is to use Xometry’s instant quoting feature and metal 3D printing service to get your parts printed on-demand.

Precise metal 3D printing on order in Sprint 3D
Metal 3D printing - additive manufacturing of metal products, which is rightfully one of the most promising and rapidly developing areas in 3D printing as such. The technology itself originates from the conventional sintering of materials used in powder metallurgy. But now it has become more perfect, accurate and fast. And today SPRINT3D offers you metal printing on 3 D printer on really favorable terms. But first, a little information about the production process itself and its capabilities.
Selective Laser Fusion Technology
SLM or Selective Fusion Technology is a type of direct metal printing that achieves a density of 99. 5%. The difference is especially noticeable when compared with models obtained by conventional casting. This indicator is achieved due to the introduction of the latest technologies in the hardware part:
- The use of special rollers for compacting powders and, as a result, the possibility of using powders with a particle size of 5 microns.
- Bulk density increase to help compact end products.
- Creates a rarefied atmosphere of inert gases, which ensures maximum purity of the material, no oxidation, and eliminates the risk of introducing third-party chemical compounds into the composition.
But most importantly, the modern 3 D Metal Printer makes it easy to customize the configuration for printing with a specific metal powder. Thus, even with inexpensive material, you can get a first-class result. But only if you use high-quality modern equipment. And here we are ready to surprise you too!

Delivery throughout Russia and CIS countries
installations for 3 D metal print, which we use
Production quality is a key requirement that we set ourselves. Therefore, in our work we use only professional equipment with wide possibilities for metal printing. Let's take a closer look at each of the production units.
Production unit SLM 280HL
SLM 280HL is a development of the German company SLM Solutions GmbH, which uses the technology of layer-by-layer laser melting of powder metal materials. The installation is equipped with a large working chamber and allows you to create 3D objects with dimensions of 280x280x350 mm. Among the main advantages of printing with this unit are:
- Small minimum thickness of the applied layer - 20 microns.
- Filling the working chamber with an inert gas, which allows you to work with various reactive metals.
- Print speed up to 35 cm/hour.
- Construction layer thickness – 30 and 50 µm.
- Power - 400 W.
A special highlight is the patented powder feed system, which delivers significantly faster print speeds than most production machines in the same price range. We use the following materials in production:
- Stainless steel (domestic 07X18H12M2 (Polema), 12X18H10T and imported 316L).
- Tool steel (imported 1.2709).
- Heat-resistant alloys 08KhN53BMTYu (similar to Inconel 718, produced by Polem) and EP 741 (produced by VILS).
- Cobalt Chrome (COCR)
The SLM 280HL 3D printer can be used to create all kinds of metal components, prototypes and end products. If necessary, we can provide small-scale production.
ProX 100 production unit
ProX 100 is a compact 3 D metal printing unit developed by the American company 3D Systems. It uses direct laser sintering technology, which ensures high speed and precision of production. Among the main characteristics it is worth highlighting:
- The size of the working chamber is 100x100x80 mm.
- Construction layer thickness – 20 and 30 µm.
- Power - 50 W.
ProX 100 allows you to create prototypes that cannot be developed by standard methods, provides short lead times, guarantees the absence of material porosity and high part density. In addition, we note the standardized quality of all products, regardless of their structure. At the moment, the model is actively used in dentistry when creating high-precision prostheses, but it has found wide application in other industries:
- Manufacture of engines and their individual parts.
- Development of medical equipment.
- Printing jewelry and even contemporary art.
In printing, we use the KX28M6 cobalt-chromium alloy (Polem's production), originally developed for additive technologies when creating endoprostheses.
Metal 3D printing - current application
Many experts argue that 3D printing as such has not yet fully revealed its potential. For example, Elon Musk plans to use technology in the colonization of Mars to build administrative and residential buildings, equipment and technology right on the spot. And this is quite real, because already now the technology of three-dimensional metal printing is actively used in various industries: The high precision of production and relatively affordable price have made 3D printing very relevant in this industry.
And this is only a small part of what can be created on modern equipment. Almost all metal products that you need can be created using metal 3D printing technology. And if this service is relevant for you, contact SPRINT3D. We will undertake work of any complexity and volume. And most importantly - we will provide first-class results!

Metal 3D Printing - A Fundamental Guide
There is no hotter trend in 3D printing today than metal. We will talk about metal printing at home, how it is done on an industrial scale, about technologies, applications, printers, processes, prices and materials.
Metal 3D printing has grown in popularity over the past few years. And this is quite natural: each material offers a unique combination of practical and aesthetic qualities, can be suitable for a wide range of products, prototypes, miniatures, decorations, functional details and even kitchen utensils.
The reason metal 3D printing has become so popular is because the printed objects can be mass-produced. In fact, some of the printed parts are just as good (if not better) than those made with traditional methods.
In traditional production, working with plastic and metal can be quite wasteful - there is a lot of waste, a lot of excess material is used. When an aircraft manufacturer makes metal parts, up to 90% of the material is simply cut off. 3D printed metal parts require less energy and waste is reduced to a minimum. It is also important that the final 3D printed product is up to 60% lighter than a traditional part. Billions of dollars could be saved in the aviation industry alone—mainly through weight savings and fuel savings.
So, what do we need to know about metal 3D printing?
Metal 3D printing at home
If you want to make objects that look like metal at home, your best bet is to use metallized PLA filaments. ? Given the extreme heat required for true metal 3D printing, a conventional FDM 3D printer will not be able to do this.
It is unlikely that in this decade it will be possible to print with liquid metal at home. Until 2020, you probably will not have a printer specialized for this purpose at home. But in a few years, as nanotechnology advances, we may see significant developments in new applications. This can be 3D printed with conductive silver, which will emit in much the same way as it does in 2D home printers. It will even be possible to mix different materials like plastic and metal in one object.
Materials for metal 3D printing at home
Even though you can't print actual metal objects at home, you can turn to plastic filament that has metal powders added to it. ColorFabb, ProtoPasta and TreeD Filaments all offer interesting metal-PLA composite filaments. These filaments, containing a significant percentage of metal powders, remain pliable enough to be printed at low temperatures (200 to 300 Celsius) on virtually any 3D printer. At the same time, they contain enough metal to make the final object look, feel, and even weigh like metal. Iron-based filaments even rust under certain conditions.
But you can go further. Typically, up to 50 percent metal powder is added to 3D printing filament. Dutch company Formfutura says they have achieved 85 percent metal powder with 15 percent PLA. These filaments are called MetalFil Ancient Bronze and Metalfil Classic Copper. They can be printed even at "moderate" temperatures from 190 to 200 degrees Celsius.

Here are the key points about metal printing at home
- Gets a unique metal surface and look
- Ideal for jewelry, figurines, housewares, replicas
- Durability
- Objects are not flexible (structure dependent)
- Objects do not dissolve
- Not considered food safe
- Typical print temperature: 195 - 220°C
- Extremely low shrinkage on cooling
- No table heating required
- Printing complexity is high, requires fine tuning of nozzle temperature, feed rate, post-processing
Preparing your home printer for metal 3D printing
Since getting metal 3D prints is more difficult than usual, you may need to upgrade your 3D printer nozzle, especially if you are an entry-level printer. The metal filament wears it out quickly. There are hard-wearing hot-ends (like the E3D V6) that are themselves made of metal. They can withstand high temperatures and fit most printers. Be prepared for the fact that the nozzles will have to be changed frequently, because the metal filament is very abrasive.
You will also need to take care of the final finishing of the surface (cleaning, sanding, oiling, waxing or priming) so that the printed metal object shines as it should.
How much does metal filament for 3D printing cost?
And what about metal filament for 3D printing? - you ask. Here are some examples:
- ColorFabb's 750 gram Bronzefill spool is $56.36
- ColorFabb 750g Copperfill Coil $56.36
- Protopasta's Polishable Stainless Steel PLA Composite is $56 for 56 grams of
- Protopasta's Rustable Magnetic Iron PLA Composite is $34.99 for 500 grams of
Industrial metal 3D printing
But what if you want a better result or even full metal 3D printing? Should a real "metal" 3D printer be purchased for business needs? We wouldn't recommend it - unless you're going to be doing it every day. A professional metal 3D printer is expensive: EOS or Stratasys devices will cost you 100-500 thousand dollars. In addition, the costs will be even greater, since you will have to hire an operator, a worker to maintain the machine, as well as to finalize the printouts (polishing, for example). Just a note: In 2016, an affordable metal 3D printer didn't exist.
Lowering Metal 3D Printing Costs
If you are not going to open a metal 3D printing business, but still need a professionally 3D printed metal part, it is better to contact the appropriate company that provides such services. 3D printing services like Shapeways, Sculpteo and iMaterialise offer direct metal printing.
They currently work with the following metal materials in 3D printing:
- aluminum
- steel
- brass
- copper
- bronze
- sterling silver
- gold
- platinum
- titanium
If you are a jeweler, you can also order wax models for casting in precious metals.
If we talk about wax models, then in most cases they (with subsequent melting) are used when printing with metals (including gold and silver). Not all orders are carried out directly by these firms. They usually turn to other metal 3D printing companies to complete the order. However, the number of such services around the world is growing rapidly. In addition, metal 3D printing techniques are becoming more and more common in companies that offer such services.
The reason 3D printing is so popular with large companies is that it can be used to build fully automated lines that produce "topologically optimized" parts. This means that it is possible to fine-tune the raw materials and make the components thicker only if they must withstand heavy loads. In general, the mass of parts is significantly reduced, while their structural integrity is preserved. And this is not the only advantage of this technology. In some cases, the product turns out to be significantly cheaper and affordable for almost everyone.
Please note that metal 3D printing requires special CAD software for modeling. It is worth paying attention to the recommendations of Shapeways - 3D printing metal guidelines. To delve further into the topic, check out Statasys’ information on related 3D printers and the nuances of metal 3D printing.
Here are some examples of Benchy test model prices for metal 3D printing:
- Metal plastic: $22.44 (former alumide, PLA with aluminium)
- Stainless steel: $83.75 (plated, polished)
- Bronze: $299.91 (solid, polished)
- Silver: $713.47 (solid, mirror polished)
- Gold: $87.75 (gold plated, polished)
- Gold: $12,540 (solid, 18K gold)
- Platinum: $27,314 (solid, polished)
As you might expect, solid metal 3D printing prices are quite high.
Metallic 3D printing. Applications
GE LEAP aircraft engine parts 3D printed at Avio Aero (Photo: GE)
There are several industries already using 3D printers to make everyday objects - you may not even know that these objects are printed.
- The most common case is surgical and dental implants, which are considered the best option for patients today. Reason: they can be tailored to individual needs.
- Another industry is jewelry. Here, most manufacturers have abandoned resin 3D printing and wax casting, switching directly to metal 3D printing.
- In addition, the aerospace industry is becoming more and more dependent on 3D printed metal objects. The Italian company Ge-AvioAero was the first to do all-metal 3D printing. It manufactures components for LEAP aircraft engines.
- Another industry targeting metal 3D printing is automotive. BMW, Audi, FCA are seriously considering this technology, not only for prototyping (3D printing has been used for this for quite some time), but also for making real parts.
Before metal 3D printing really takes off, however, there are some hurdles to overcome. And first of all, this is a high price, which cannot be made lower than during molding. Another problem is the low production speed.
Metal 3D printing.
Technologies
Most metal 3D printing processes start with an "atomized" powder
You can talk a lot about "metal" 3D printers, but their main problems remain the same as any other 3D – printers: software and hardware limitations, material optimization and multimateriality. We won't talk too much about the software, we'll just say that most of the major specialized software companies, such as Autodesk, SolidWorks and solidThinking, try to emphasize as much as possible the fact that as a result of the 3D metal printing process, you can get any shape you want.
In general, printed metal parts can be as strong as parts made by traditional processes. Parts made using DMLS technology have mechanical properties equivalent to casting. In addition, the porosity of objects made on a good "metal" 3D printer can reach 99.5%. In fact, manufacturer Stratasys claims that 3D printed metal parts perform above industry standards when tested for density.
3D printed metal can have different resolutions. At the highest resolution, layer thickness is 0.0008 - 0.0012" and X/Y resolution is 0.012 - 0.016". The minimum hole diameter is 0.035 - 0.045". formed layer)
The metal 3D printing process used by most relevant large companies today is called Powder Bed Fusion. This name indicates that some source of energy (a laser or other energy beam) melts an "atomized" powder (i.e., a metal powder that is carefully ground into spherical particles), resulting in layers of a printed object.
There are eight major manufacturers of metal 3D printers in the world that already use this technology; while we are talking here, there are more and more such companies. Most of them are in Germany. Their technologies are called SLM (Selective Laser Melting - selective laser fusion) or DMLS (Direct Metal Laser Sintering - direct metal laser sintering).
Metal 3D-printing process No. 2:
Binder Jetting (spraying the binding substance)
under 3DP-technology of Exone metal objects are printed by binding the powder before its binding in the mining (photos : ExOne)
Another professional approach that also uses a powder base is called Binder Jetting. In this case, the layers are formed by gluing metal particles together and then sintering (or fusing) them in a high-temperature furnace, just like it is done with ceramics.
Another option, which is similar to working with ceramics, is mixing metal powder into metal paste. A pneumatically extruded 3D printer (similar to a syringe bioprinter or an inexpensive food printer) forms 3D objects. When the required shape is reached, the object is sent to the furnace, i. e. in the mountains
This approach is used in the Mini Metal Maker, apparently the only inexpensive "metal" 3D printer.
Metal 3D printing process #3: 9Metal deposition This is not entirely true. Of course, on some desktop device, simply fusing metal threads onto the base will not work. However, very large steel companies can do it. And they do. There are two options for working with "metal surfacing".
One is called DED (Directed Energy Deposition) or Laser Cladding. Here, a laser beam is used to melt the metal powder, which is slowly released and solidifies as a layer, and the powder is fed using a robotic arm.
Normally the whole process takes place in a closed chamber, but the MX3D project uses conventional 3D printing techniques to build a full-size bridge. Another option for metal fusion is called EBAM (Electron Beam Additive Manufacturing - additive electron beam technology), which is essentially soldering, in which a very powerful electron beam is used to melt 3 mm titanium wire, and the molten metal forms very large finished structures. As for this technology, its details are known so far only to the military.
Metallic 3D printing. Metals
3D Printing Metal #1: Titanium
Pure titanium (Ti64 or TiAl4V) is one of the most commonly used metals for 3D printing and is definitely one of the most versatile, strong and lightweight. Titanium is used both in the melting process in a preformed layer and in the process of spraying a binder and is used mainly in the medical industry (for the manufacture of personal prostheses), as well as in the aerospace industry, automotive and machine tools (for the manufacture of parts and prototypes). But there is one problem. Titanium is very reactive and explodes easily in powder form. Therefore, it is necessary that titanium 3D printing takes place in a vacuum or in an argon environment.
3D printing metal #2: Stainless steel
Stainless steel is one of the cheapest 3D printing metals. At the same time, it is very durable and can be used in a wide range of manufacturing and even artistic and design applications. The type of steel alloy used also contains cobalt and nickel, is very difficult to break, and has a very high elasticity. Stainless steel is used almost exclusively in industry.
3D Printing Metal #3: Inconel
Inconel is a superalloy manufactured by Special Metals Corporation, its registered trademark. The alloy consists mainly of nickel and chromium and is very heat resistant. Therefore, it is used in the oil, chemical and aerospace (for black boxes) industries.
3D Printing Metal #4: Aluminum
Due to its lightness and versatility, aluminum is very popular in 3D printing. Aluminum alloys are commonly used.
3D Printing Metal #5: Cobalt Chrome
gap). It is most commonly used in the manufacture of turbines, dental and orthopedic implants, where 3D printing has become the dominant technology.
3D printing metal #5. Copper and bronze
With few exceptions, copper and bronze are used in wax melting processes, rarely in layer melting. The fact is that these metals are not very suitable for industry, they are more often used in the manufacture of works of art and crafts. ColorFabb offers both metals as the basis for a special metal filament.
3D printing metal #6. Iron
Iron, incl. magnetic, also mainly used as an additive to PLA-based filaments, which are produced, for example, by ProtoPasta and TreeD.
3D printing metal #7. Gold, Silver and Other Precious Metals
Most preformed melt companies can 3D print precious metals such as gold, silver and platinum. Here, along with the preservation of the aesthetic properties of materials, it is important to achieve optimization of work with expensive starting powder. Precious metal 3D printing is required for jewelry, medical applications and electronics.
Metallic 3D printing. Printers
Do not hesitate - the purchase of a metal 3D printer will not pass without a trace on your budget. It will cost at least 100-250 thousand dollars. Here is a list of a variety of "metal" printers, some of which can be found in firms providing 3D printing services.
Metal 3D Printer #1:
Sciaky EBAM 300 - Metal Filament Printing
If you need to print really large metal structures, Sciaky's EBAM technology is your best bet. By order, the device can be built in almost any size. This technique is used mainly in the aerospace industry and the military.
Sciaky's largest production printer is the EBAM 300. It prints objects in a volume of 5791 x 1219 x 1219 mm.
The company claims the EBAM 300 is also one of the fastest industrial 3D printers on the market. A three-meter-sized titanium part for an aircraft is printed on it in 48 hours, while the material consumption is about 7 kg per hour. In general, forged parts that usually take 6-12 months to complete can be made in 2 days with this 3D printer.
The metal layers are first cut and then ultrasonically welded. The largest Fabrisonic 7200 printer operates in a volume of 2 x 2 x 1.5 m. The metal powder 3D printer is the Concept Laser XLine 1000. It has a modeling volume of 630 x 400 x 500 mm and is the size of a house.
Its German company, one of the main suppliers of 3D printers for aerospace giants like Airbus, recently introduced a new machine, the Xline 2000.
This machine uses two lasers and has a working volume of 800 x 400 x 500 mm. Uses LaserCUSING laser technology (a variant of selective laser fusion) from Concept Laser, which allows you to print alloys of steel, aluminum, nickel, titanium, precious metals and even some pure substances (titanium and stainless steel).
