- New GTarc Machine presented during EMO show
- 3DMP® uses wire instead of powder as basic material
- Economical manufacturing of parts up to 3 m3 and 3,000 kg
- GTarc Machine available as 3- or 5-axis machining centre
- Significantly lower investment compared to other 3D printing technologies
GEFERTEC GmbH will present the new GTarc machining centre during the EMO show (September 18th till 23rd) in Ha-nover. The revolutionary 3DMP® technology will be presented to the public for the first time. This new additive manufacturing technology en-ables the cost-efficient and fast production of near-net-shape metal parts. Quality of the parts is comparable to standard manufacturing methods. The 3DMP® technology is based on well-proven electric arc welding and is therefore using wire as original material, so the final part is formed welding layer by welding layer. This new method offers a range of advantages compared to other additive manufacturing tech-nologies, which are based on powder as original material. For example, there is no elaborate powder handling, and most standard materials are available as wire at significantly lower prices. The main benefit is the high production speed, which can be up to 600 cm3 per hour depending on the material. This is why the machining centre is ideally suited for the production of larger parts made of steel, nickel, titanium, or aluminium.
The GTarc machining centre, which will be presented during the show for the first time, is available as a 3-axis version for parts up to 3 m3 and as a 5-axis version for parts up to 0.8 m3. A special 3DMP® CAM soft-ware calculates the data out of the CAD-modelled part, which enables the CNC-control unit to position the welding head with high precision. The machine produces the near-net-shape part fully automatically. The finishing of the part is done by standard CNC milling machine. Com-pared to other manufacturing methods 3DMP® has a maximum material utilisation, which leads to substantial cost savings, especially when ex-pensive materials like titanium are used. Depending on the application manufacturing costs decrease up to 60 %. The GTarc machine is built in a modular way, making future upgrades very easy. For example, cus-tomers can upgrade the 3-axis version with a pan-tilt-table to obtain the 5-axis version. Prices of the new GTarc machining centres are in the range of a smaller CNC milling machine and are considerably lower than comparable machines for 3D printing.
