3D plastic printing: cost-effective investment casting patterns and design models

3D plastic printing enables cost-effective and time-saving production of investment casting patterns and design models. The models are produced step by step by applying a particle material in layers and selectively bonding it with a binder. PMMA (polymethyl methacrylate), an acrylic plastic, is used as the particulate material. Large formats with a length of one meter, a width of 60 centimeters and a height of 50 centimeters are possible.
