UPDATE: we have released our list of the best 3D printers with meta-rating calculated using ratings from reliable sources. Find out which are the 20 top rated 3D printers currently on the market!
Metal 3D printing is one of the most fascinating sides of 3D printing. Talking about metal 3D printers brings scenes of Terminator 2 to mind, with the infamous scene where the T1000 rebuilds itself from liquid metal. But metal additive manufacturing is no longer a science-fiction technology: it is a reality, and perhaps the next big thing in the crazy world of 3D printing.
Although it is not yet possible to build a T1000 robot using a metal 3D printer, there are many industrial applications for metal additive manufacturing. Major companies in aerospace and automobile have been using metal 3D printing for years, not only for advanced prototyping purposes but also to produce final parts. Additive manufacturing can indeed produce stronger metal parts by 3D printing complex parts in one piece, thus avoiding welding parts together.
There are several metal additive manufacturing technologies available commercially today, which can be regrouped in four main categories: powder bed fusion, binder jetting, material jetting and direct energy deposition. Each manufacturer of metal 3D printers masters either one or several variations of these 3D print technologies, often through proprietary technologies protected by patents.
In September 2016, General Electric launched a bid to acquire two major companies in metal additive manufacturing, Arcam and SLM Solutions, for a combined value of $1.4Bn. This move marked a new phase in the integration of metal additive manufacturing into the broader industrial landscape.
We decided to learn more about the state of metal additive manufacturing and we realized there are actually more companies involved in metal 3D printing than we thought! In our 3D printers comparison engine, we list 25 companies building metal 3D printers. We have done the breakdown of metal 3D printers manufacturers by country in the table below, with more details in the article under.
Metal 3D printer manufacturers
Germany and the United States lead the pack with five metal additive manufacturing system manufacturers each. In 2015, the market leader in metal 3D printers sales was the German company EOS, with around 500 units sold and a revenue of $188m (source: CONTEXT). China and Japan follow closely behind with four manufacturers each, although it is important to note that these manufacturers have a far less established presence on the global market.
To get the full report on the metal 3D printer brands currently on the market, check our list below. We’ve categorized these metal additive manufacturing companies by 3D print technology:
POWDER BED FUSION METAL 3D PRINTERS
Arcam, or Arcam AB, is a metal 3D printer manufacturer founded in 1997 in Sweden. Arcam manufactures Electron Beam Melting (EBM) industrial 3D printing systems. EBM is a 3D printing technique used to build solid metal parts from metal powders. Arcam was purchased in September 2016 by US conglomerate General Electrics. GE offered $685 million to acquire a majority stake in the Swedish additive manufacturing company, along with a $762 million bid to acquire German metal 3D printing company SLM Solutions. The total revenue for Arcam was $42m in 2015.
3D Systems 🇺🇸
The famous American 3D printing giant has a broad portfolio of 3D printing technologies, including Direct Metal Printing (DMP). This metal additive manufacturing technology is used in their ProX line of metal 3D printers. It’s interesting to note that this technology was not developed by 3D Systems but integrated through the acquisition of French metal 3D printer manufacturer Phenix Systems in 2013.
SLM Solutions 🇩🇪
SLM Solutions is a German company founded in 2011. They make advanced metal 3D printers for industry, based on the Selective Laser Melting technology (SLM). SLM Solutions had a revenue of $63m in 2015.
EOS was founded in 1989 in Germany. EOS is a pioneer in the development of Direct Metal Laser Sintering (DMLS) systems. EOS is the global leader in metal additive manufacturing systems with around 500 metal 3D printers shipped in 2015.
Concept Laser 🇩🇪
Concept Laser is a German company founded in 2000. Concept Laser is one of the world’s leading providers of industrial-grade metal 3D printers. Their metal additive manufacturing systems are based on the LaserCUSING® 3D printing process, where a laser melts metal powders to form a metal object. Concept Laser is for sale with rumors of an imminent acquisition, in the wake of the GE bid for Arcam and SLM Solutions in September 2016.
Renishaw is a engineering company from the United Kingdom, founded in 1973. In addition to metal 3D printers, Renishaw produces a wide range of industrial metrology and prototyping systems.
Realizer is a German manufacturer started in 1990. The produce industrial-grade metal 3D printers based on the Selective Laser Melting (SLM) technology. Their additive manufacturing machines are mostly used for Jewelry and Dental applications.
