3DMetalWIRE

MachineDescription

The 3DMetalWIRE is currently in development and extends Aconity’s equipment portfolio to powder free wire-based 3D metal printing. The laser-based system combines a compact machine design with a large build space of Ø 400 mm x H 400 mm, perfectly suited for producing mid-sized AM parts.

A force-controlled wire feed is enveloped by a shielding gas nozzle and a unique Corona-shaped intensity profile of the laser beam, enabling direction-indipendent material deposition. By processing standardized welding wires, large metal components may be produced at cut costs, facilitated handling and improved quality assurance for truly industrialized manufacturing. Real time control of the 6-axis robot and 2-axis rotary tilt table with infinite rotation allow for upmost flexibility in terms of part complexity, whereas a powerful prehaeting of up to 500 °C reduces internal stresses and extends the scope of applicable materials.
