How It WorksA metal 3D printing process in 3 easy-to-manage steps
Step 1 – Prepare your files
Secure, web-based software fabricates from STL or CAD files, automatically generating supports and control parameters based on part geometry and material.
Step 2 – 3D Print
Layer by layer, a green part is shaped by extruding bound metal rods—metal powder held together by polymer binders—in a process called Bound Metal Deposition™.
Step 3 – Sinter
Once printed, parts are placed in the furnace. As the part is heated to temperatures near melting, the binder is removed and metal particles fuse together causing the part to densify up to 98%.
Introducing the new, swappable 250μm printhead that includes supporting software profiles. This enables new geometries and applications, resulting in achieving smaller parts and fine features with an improved surface.
There are camera’s everywhere, so why not put one in the in-chamber build plate? This camera captures live footage of the part as it prints, and is accessible in your web browser. Users now have complete insight of their part, and have the ability to monitor print success.
Stackable shelving is a new feature that increases part capacity of the debinder and furnace, giving greater throughput. Increased workload volume addresses bottlenecks typical at the debind sinter stages.
To achieve high quality parts, a new retort box design has been added to support thermal uniformity.
Eliminate some cost of consumables and achieve lower cost-per-part with external gas connections.
Studio Fleet is a custom and configurable metal 3D printing hardware solution for producing complex metal parts in low-mid volume.
MaterialsThe metallurgy behind the Studio System™ is built upon the material science and established powder supply chain of the metal injection molding (MIM) industry.
When combined with Desktop Metal’s expansive in-house expertise in material processing, binder compounds, and metal 3D printing, the result is high-quality metal parts with affordable material costs.

- 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.
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.
Metal 3D printing materials
Which metals can you 3D print?
A growing number of metals and metal alloys can be 3D printed. These are the main ones:
- Aluminum
- Titanium
- Nickel, Inconel
- Copper
- Bronze
- Cobalt, Cobalt-Chrome
- Steels (tooling, maraging, stainless)
- Precious metals (gold, silver, platinum)
Which metal 3D printing material formats are available?
Metal 3D printing material can be found in various formats, catering to different metal 3D printing methods.
The most common are:
- Powder

- Filament
It is also possible to find metal 3D printing resin as well as metal sheets for lamination-based 3D printers.
Metal 3D printer price: how much does a metal 3D printer cost?
Industrial metal 3D printer prices generally range from about $30,000 to over one million dollars for the most premium, industrial-grade metal additive manufacturing systems.
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.
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!

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. nine0009
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.
nine0009
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. nine0009
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. nine0009
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. nine0009
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. nine0009
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.
nine0009
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.

- 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. nine0021
- 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. nine0009
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. nine0009
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. nine0009
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). nine0009
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. nine0009
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". nine0009
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. nine0009
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. nine0009
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. nine0009
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. nine0009
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. nine0009
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. nine0009
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.

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. nine0009
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). nine0009
