Gefertec Debuts arc80X for Metal Printing

3D metal printing with wire arc additive manufacturing (WAAM) is being used in many applications. GEFERTEC, a German company invested in WAAM, is now expanding the range of available machines with its new arc80X series. 

More Automation

For the machine’s kinematics, GEFERTEC relies on a CNC-controlled linear axis system. In the three-axis version, the production system has an assembly space of 2x2x2 m and can produce parts with a total mass of up to 8 tons. The five-axis version prints parts with a diameter of up to 0.9 m and a height of up to 1.4 m. The machines offer more automation to improve production efficiency and reduce personnel requirements. Automated functions include integrated tool measurement, gas nozzle cleaning, wire cutting and replacement of wear parts.

The new machine generation also enhances process monitoring. The process monitor records and stores all relevant data during the printing process. This allows comprehensive documentation for quality assurance and process optimization. An integrated pyrometer measures the part temperature. The optional inert gas box enables printing in a closed inert gas atmosphere. 

Machine Design

The machine is designed as a complete production system based upon the WAAM process. Traditional metal inert gas welding is used for the additive manufacturing of parts. The arc machines combine this with special CAM software and a Sinumerik control architecture. The process offers high build rates, according to the company. The machines are already being used extensively in industrial applications, such as mass production of turbine components in the energy sector.
