Abstract

The invention relates to a novel support material for the fused deposition modelling process for producing three-dimensional objects. The invention relates more particularly to a 3D printing process involving support materials which are easier to remove than in the prior art. The support materials according to the invention are styrene-maleic anhydride copolymers for example.
