From CAD to Casting

Rapid Parts' metal rapid prototyping process combines the speed of 3D printing technologies with the quality of investment casting.

Investment casting has long been known for its ability to provide parts with high complexity and fine surface finish in an enormous range of metals. Until recently the time taken to produce accurate sacrificial wax patterns to feed into the casting process has been an obstacle to short lead-times. This is no longer the case using modern 3D rapid prototyping processes. Several processes produce parts that can be used as sacrificial patterns for investment casting. Rapid Parts uses 3DSystems Thermojets to produce wax-like patterns in a matter of hours from customers' CAD data. Part size is not restricted to the printer's build size as we can precisely assemble many waxes to make patterns as large as our foundry can handle.
