List of metal 3D printing processes commonly used by the company

Joule printing: the Joule printing of digital alloys looks much like ded, but the metal wire is melted by electric current rather than heated by electric arc or light beam. This makes printing faster. It has been proved that it can print up to 2 kg of titanium per hour.

Liquid metal additive manufacturing: Vader systems has created liquid metal additive manufacturing technology, which deposits liquid metal droplets at 1200 ° C in a manner similar to inkjet printers.
Electrochemical deposition: exaddon's Ceres nano metal 3D printer can use electrochemical deposition to make metal objects smaller than the width of human hair.

DLP metal printing: admatec and prodways provide metal DLP printing. Similar to metal material extrusion, when metal powder is mixed with photopolymer resin, 3D printing parts must undergo the same degreasing and sintering process, just like metal material extrusion method.

Cold Sprayed Metal Printing: Cold Sprayed Metal printing was originally used by NASA to build metal objects in space. The main feature is fast (6 kg of aluminum or copper per hour), and the disadvantage is not so accurate. Australian companies titomic and spee3d are the leaders in this technology.

Ultrasonic consolidation: use sound to bond thin metal foil layers together, and process the excess part of each layer before bonding the next layer of foil. Therefore, it is a combination of additive manufacturing and subtractive manufacturing. Fabrisonic's soniclayer 3D printer family uses this technology.

Laser engineering net shaping: it is a laser based method, which needs a very controllable environment. This process requires a sealed chamber, usually argon to remove oxygen and keep the oxidation level as low as possible. The power range of lens laser is from 500W to 4kw. It can be used to process titanium, stainless steel and Inconel. Despite the difficulties in maintaining the anaerobic chamber, lens provides users with better accuracy and control.

Electron beam free form manufacturing: originally developed by NASA, it is a method mainly used in the aerospace industry. This method can produce complex geometry without wasting any materials, and can create lightweight shapes to promote fuel saving.
