The Protos X400 is a novelty in the low-cost 3D printing segment, according to supplier German Rep Rap, because it meets the requirements of professional construction and development departments for prototyping as well as small batch production.

The company said the unit offers a layer thicknesses up to 0.1 mm and a printing space of 400 x 400 x 350 mm for precise models with a volume of up to about 56 litres. It explained that this means the Protos X400 reaches a printing speed of up to 15 cubic mm per second, depending on the material used, the resolution and the complexity of the object being printed.
