Intended use

The VP75 Additive Manufacturing System has been designed and built for manufacturing three-dimensional workpieces of nearly random geometries from common 1.75 mm thermoplastic filament strands.
The machine features an advanced hot-end geometry with an extrusion temperature up to 500°C. In combination with the heated build chamber (up to 80°C) and the heated built plate (up to 150°C), this makes the VP75 suitable for processing a variety of materials. It is therefor capable of performing regular additive manufacturing tasks with standard thermoplastics as well as special jobs with technical plastics.
Contact Kühling&Kühling for more detailed information on available and applicable materials.

The VP75 is intended for industrial and commercial use. It is not valid for the operation in an explosive atmosphere.
