Polymer 3d printing

Functional polymer components in PA12 and PA12-GB. SLS and MJF processes with consistent material properties.

Industrial polymer 3D printing technology

3DStep uses two industrial polymer printing technologies for component production: selective laser sintering and HP Multi Jet Fusion. Both processes are based on validated parameters, documented material data and controlled production steps.

Polymer parts can be manufactured, dyed and finished according to the application’s functional and quality requirements.
