Overview of the best metal 3D printers in 2020

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.

Desktop Metal Bound Metal Deposition™
Most extrusion-based metal 3D printing processes include these steps. The above illustration is sourced from Desktop Metal (Bound Metal Deposition™ process).

Desktop Metal Studio

  • Build volume: 300 x 200 x 200 mm

XXL-sized metal 3D printers for industrial production

For those that require very large metal parts, there are several huge, industrial machines that offer gigantic build volumes for industrial production. To name a few:

Metal 3D printers from China

There has recently been a lot of growth in the metal 3D printer market in Asia, and more specifically in China. Some Chinese brands have been upping their game in that respect, providing industrial-grade metal 3D printing options:

However, we feel that they are not yet playing in the same league as the 3D printers from our main selection, mostly due to a lack of distribution networks, after-sales service and training, and other factors which tend to matter when considering them together as a whole.

R&D metal 3D printers for labs

In certain cases, metal 3D printers are used for research purposes to develop and test new materials. There are a few machines that are specifically designed for this:

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
  • Wire
  • 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.

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.

More information: How Strong Are 3D-Printed Metal Parts? Metallurgical Integrity in Metal Additive Manufacturing

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 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.
