metal 3d printer buyers guide

Though metal 3D printing has been around since the 20th century, only recently have innovative developments and a growing demand for accurate metal part rapid prototyping led to an exploding range of metal 3D printer systems by dozens of successful metal 3D printer companies.

Different metal 3D printers use lasers, beams, jets and binders, and even deposition methods similar to FDM to create precise and durable metal 3D printed parts.

Here are some of the most effective, efficient, precise and versatile metal additive manufacturing systems on the market. If you are interested in purchasing a metal AM system, we may be able to help connect you with a local team to discuss your needs.

Types of metal 3D printer

Though many metal 3D printer manufacturers offer printers with their own patented and branded technologies, they are usually based around a few general metal 3D printing technologies. These include:

Advantages of metal 3D printers

advantages of 3d printing metals
  • Increasingly large range of materials: these include common metals like aluminum, stainless steel, tooling steel, and titanium, as well as various other alloys and composites with a range of different advantages and mechanical properties.
  • Quicker production: the improved rapid prototyping capabilities allow companies to go from design to final production stage in record time. Prototypes and designs can be quickly 3D printed, tested, and modified and re-printed in record time with metal 3D printers.
  • Cost savings: as 3D printing is additive rather than subtractive, only the required material is used, with no wasted metal material left over to increase costs. Additionally, parts do not need to be printed solidly – they are strong even at 20% infill – meaning a large cost saving from using less material, and parts can be far lighter; a huge advantage in industries such as automotive and aerospace where saving even a kilogram can save millions.
  • New design possibilities: metal 3D printers can create parts with geometries that cannot be created using traditional methods, or that previously needed to multiple parts. These parts can be printed as one part on a metal 3D printer, leading to stronger parts.

The best metal 3D printers

We have separated our metal 3D printer buyer’s guide into two parts, with part 1 concerning metal printers for smaller scale production, such as in universities and laboratories, and with part 2 concerning larger scale metal 3D printers for industrial metal printing.

  • Price: $100,000
  • Metal 3D printer technology: ADAM (Atomic Diffusion Additive Manufacturing)

Markforged have taken the 3D printing world by storm, now having taken over $130M in investment to bring to market a wide variety of FDM 3D printers as well as metal printers.

The Metal X uses ADAM technology somewhat similar to FDM 3D printing, where metal filament is extruded within more standard polymer filaments, before the 3D printed part is heated to remove the plastic while sintering the metal part to strengthen it.

markforged metal x

This brings the simplicity of FDM to metal 3D printing, and the low price of $100,000 reflects that. Metal 3D printing with a plastic binder and metal powder saves money, and leads to high quality parts that can be 3D printed with ease. It can print a variety of metal powder materials, including stainless and tooling steel, titanium, Inconel, aluminium, and copper.

This innovates further on Markforged’s original selling point: FDM-style 3D prints mixed with carbon fiber to make them far stronger. These carbon fiber 3D printers, such as the Onyx range, offer exponentially stronger parts than is possible with PLA filament or ABS. Overall, the Metal X combines FDM with metal 3D printing to offer an efficient and low-cost solution that is far more accessible than many metal 3D printers today.

Desktop Metal Studio System 2

  • Build volume: 300 x 200 x 200 mm
  • Price: Requires a Quote
  • Metal 3D printer technology: Bound Metal Deposition

Building on the extraordinary success of the Studio System, the 2nd iteration is still an ideal office-friendly metal 3D printing system you can fit on most desktops, but still able to produce high quality prototypes and end-use parts for industry.

The technology it uses, Bound Metal Deposition, is similar to FDM, instead using metal rods rather than plastic filament spools to build the part. The metal rods used are infused with the polymer binder, so that when they are heated and extruded, “the metal powder just comes along for the ride,” according to Desktop Metal.

The Studio System 2 further streamlines this already simple metal additive manufacturing workflow, condensing the previously three-stage process into two — combining the debinding and sintering stage. Now you simply place your green unsintered part in the furnace and heat it after printing, and it’ll gain the mechanical properties and densities needed for its end use.

Desktop Metal highlight the Studio System 2’s improvements, allowing for “higher quality end-use metal parts through a more streamlined and accessible process, and with an even smaller footprint,” according to CEO Ric Fulop. The 300 x 200 x 200 mm print volume should be more than enough for small to medium sized metal parts, and the metal 3D printer can print layers as thin as 50 microns.
