More 3DP Precision for Investment Casting Patterns

A finer polymethyl methacrylate formulation is the basis for a new additive manufacturing process that will have positive effects for the precision of molds and cores.

The potential threat to metalcasting presented by additive manufacturing remains mostly potential. Whereas AM parts can exhibit geometric variety and precision, most AM products are not cost-effective in the volumes that metalcasters are able to achieve, or they cannot match the output of foundries and diecasters in terms of material specification, or scale, or mechanical durability. At least, not yet.
