STATUS ON SEPTEMBER 2019


Metal 3D printing has been one of the most outstanding developments in the AM industry in recent years. In 2018, Wohlers Report reported that 80% more metal 3D printing solutions had been sold compared to the previous year – today,  this figure continues to grow. An important number of new market players are joining the market, developing new 3D printers and new technologies. In recent years, an astonishing 40 manufacturers of metal 3D printers have emerged. Many of these manufacturers have introduced new technologies to deal with this material such as HP’s Multi Jet Fusion or XJet’s Inkjet technology, for example.

Today we present to the main manufacturers of metal 3D printers, we have classified them given the additive manufacturing technology: Powder Bed Fusion, Directed Energy Deposition, Material Extrusion or Binder Jetting.

Metal 3D Printers: Material Extrusion 

Desktop Metal 

Desktop Metal is an American company that wants to reduce the cost and speed of additive metal manufacturing. It recently unveiled its two printers, the Studio System available from $120K and the Production System which costs $420K. The manufacturer has already received a total investment of $200M, including from Google, BMW and GE. It has developed its own technology called “single pass jetting” which is very similar to metal injection moulding.

Markforged

Markforged was founded in 2013 by Greg Mark and first focused on 3D printing from carbon fibers. Since then, the company has started manufacturing metal additive manufacturing systems with Metal X. What distinguishes it from other machines is its relatively low cost since it is available from $100,000. Its Atomic Diffusion Additive Manufacturing (ADAM) technology should make it easier to create cheaper parts with a printing volume of 250 x 220 x 200 mm. Like Desktop Metal, its process is based on the MIM (Metal Injection Molding) technology already widely used in the industry.

Iro3D

Iro3D is an American manufacturer that came into the industry in 2018 by unveiling its metal 3D printer Iro3D. The machine looks like an FFF 3D printer, but is capable of printing metals thanks to its “Selective Powder Deposition” technology, based on extrusion technologies. Through its nozzle, the printer creates a sand crucible in which the metal powder is located. Once the printing process is complete, the part in the crucible must be sintered at more than 1180°C for about 3 hours.

Airwolf

Airwolf is a company specialized in the development of 3D desktop printers with FDM. In 2017, the company unveiled Evo Additive Manufacturing Center, an office machine capable of printing with several materials such as ABS, PLA, special filaments but also metal. Another company specialized in FDM technology has also launched into metal: Colido with its 3D printer AMSS Metal. This machine works by extrusion and with a binder.

 

Metal 3D Printers: Other Technologies 

HP Metal Jet 

Almost a year ago, the American giant HP announced the launch of its first metal solution, the HP Metal Jet. Since its arrival on the market, HP has become one of the leading manufacturers of industrial 3D printers and therefore could not miss the metal. The new metal machine is based on the projection of a binder and a metal powder, solidified layer by layer by a heat source. The binder is removed directly from the 3D printer, while the sintering step must be performed in a suitable furnace.

Digital Metal

Bought by a coal mining company, Höganäs, a few years ago, Digital Metal is a growing company that has produced more than 200,000 metal objects since its creation. Its metal 3D printer, the DM P2500, is based on Binder Jetting technology, and offers a printing volume of 203 x 180 x 69 mm, on top of not requiring any printing media. It promises fast, flexible and economical production.

ExOne

ExOne is a publicly traded German manufacturing company that specialises in industrial 3D printing machines. The German company’s 3D printers are commonly used in sectors such as automotive, aerospace, heavy equipment, and energy sectors. ExOne 3D printers use Binder Jetting technology with industrial materials to provide solutions at a lower operating cost. Currently, ExOne markets four printers: Innovative, ExOne 25 Pro, ExOne M-Flex, and ExOne M-Print.

XJet 

XJet is our only Israeli manufacturer, founded by Hanan Gothait. The company is best known for its innovative NanoParticle Jetting technology that could revolutionize metal and ceramic manufacturing. Its 3D printers allow you to create a metal object using a material composed of fine metal droplets suspended in a liquid ink. The Israeli manufacturer currently produces two printers, the X Carmel 700 and the X Carmel 1400. The video below shows the patented technology:

Vader Systems

Vader Systems is an American manufacturer specialized in 3D metal printing, founded by Scott Vader and his son Zachary Vader. The company was recently acquired for $8 million by the giant Xerox, renowned for its 2D printers. Their 3D metal printer is based on their patented technology, MagnetoJet, which manipulates a liquid metal by magnetism. The machine propels droplets of liquefied metal at 1200°C – a process that is reminiscent of the material jet process. We don’t know yet if the 3D metal printer will keep the same name, namely Vader Systems MK1 or if Xerox will change it.

Polen AM

The French Pollen AM recently unveiled two new 3D printers, a ceramic and a metal. The latter is also based on the indirect metal manufacturing process MIM (for Metal Injection Molding) and uses metal granules – 316L stainless steel, titanium and 17-4 stainless steel. Their 3D metal printer, the PAM Series M, would be available from €68,900, one of the lowest prices on the market.

Exxadon 

Exxadon is the additive manufacturing subsidiary of the Swiss nanotechnology company Cytosurge. It has developed its 3D metal printer, the FluidFM, which can print metal with a resolution as fine as 1 µm, offering a very high level of detail. It would also have a printing volume of 200 x 200 x 200 x 200 mm and was designed mainly for research purposes.

ADMATEC  

ADMATEC is a Dutch company founded in November 2013 after the success of a research project in 2012. It has developed its 3D metal printer, the AdMetalFlex 130, which is based on Digital Light Processing (DLP) technology.
