GE Additive M2 Series

The Colibrium M2 is a dual-laser metal additive machine with a 245 x 245 mm build area and up to 405 mm of Z, offered with either of two fibre laser systems: 2x1kW (cw) or 2 x 400 W (cw). Choosing between them is the main configuration decision, and the material list hints at why: one entry, Titanium Ti6Al4V ELI Grade 23 (1kW), is marked for the 1kW system specifically.

Build height deserves a second look. The envelope is given as 245 x 245 x max 405 mm (x, y, z), and the build height range is 405-313 mm depending on build plate configuration and platform thickness. A part drawn close to 405 mm tall may not fit once a thicker platform is in place. The reference clamping system is optional (EROWA, others on request), and a heating system is listed as available.

Optically the table gives a focus diameter of 61-72um and a spot size range of 70-500um, with layers of 25 - 120 μm and a scanning speed of max 4.5 m/s. Laser safety carries T2 certification, and the integrated filtering system has a 20 m2 filter surface. The material list is long. It runs through stainless, maraging and tool steels, three aluminium alloys, Nickel 718, Nickel 625 and Nickel X, four titanium entries, Cobalt CoCrMo and CoCrW, and less common choices such as Tantalum and Copper Nickel CuNi2SiCr.

Services go beyond electricity. The power supply is 3/N/PE AC 400V on a 32A connector with approx. power consumption of 28A, compressed air is needed at 6-10bar, and there are 2 gas connections with an external N2 generator as an option. The machine measures 2,739 x 2,050 x 2,781 mm (W x D x H) and weighs approx. 2,500 kg, between the Concept Laser Mlab Cusing R at approx. 600 kg and the X Line 2000R at approx. 9,500 kg (tare weight). Operating conditions are 18 - 25°C, which in practice means a temperature-controlled room.
