Vacuum casting metal is a flexible and reliable casting process commonly used to generate prototypes and industrial parts. The process requires a high quality master model - this can be the finished industrial part itself, or a model created using stereolithography (generally the case for prototyping applications). Either way, it’s essential that the master model is of perfect quality in terms of both looks and dimensions, so that no flaws are transferred to the prototype/industrial part at the end of the process.
