Colibrium Additive M2 Series 5 — Technical data

The M2 Series 5 is Colibrium Additive's current mid-size laser melting system and the successor to Concept Laser's M2 cusing; it was launched in 2021, still under GE Additive. Two fibre lasers of 400 W or 1 kW each expose a build envelope of 245 × 245 mm with a height of up to 405 mm, depending on the build plate. Layer thickness ranges from 25 to 120 µm, and spot size can be adjusted from 70 to 500 µm. The safety concept includes an integrated glovebox and floodable filter modules. Colibrium has published parameters for steels, aluminium, titanium, nickel, cobalt and copper alloys as well as tantalum for the machine.

Used M2 Series 5 machines are still young and in demand accordingly. Important points are the laser version – some parameters such as copper exist only for 1 kW –, the hours on both lasers, the unlocked software modules and an active service contract. At about 2.5 t and with a 32 A connection, installation is manageable; compressed air at 6 to 10 bar and inert gas must be available.
