The compact SLM 125 Selective Laser Melting metal 3D printer offers a build envelope of 125 x 125 x 125 mm (4.9 in³) or reduced to 50 x 50 x 50 mm (approx. 2 in³) with a single 400W fiber laser. The smallest machine in the SLM Solutions’ lineup, the SLM 125 is ideal for a variety of users, from rapid prototyping and small lot manufacturing to qualified series production and research work.

Precise, economical and suitable for research and development as well as small lot production environments, the open software architecture and system parameters allow you to make modifications according to your specific manufacturing needs. Achieve the fastest build speeds in its class from the system’s patented bi-directional powder recoater movement. Internal re-circulation of inert gas at laminar flow also provides for safe and cost-efficient gas consumption. 

The SLM 125 is equipped with software for importing CAD / STL data or slice data to configure the processes and component-specific parameters. Achieve greater system control by customizing your own construction processes through the unique, flexible and open software architecture. The system processes most metal powders through a material saving, closed-loop powder handling unit. Changing the metal powder is quick, easy and designed to lower your production costs. Further available options also increase the versatility of the system and our Laser Power and Melt Pool Monitoring quality assurance modules ensure process transparency.
