Precisely holding work pieces can be difficult, whether for production or measuring critical to quality dimensions in a metrology lab. You can rely on additive manufacturing to quickly print a mirror image fixture for these purposes. This is often the first use of 3D printing, which can quickly lead to additional end uses for the technology. Ask BC MacDonald to advise you on the best materials and printers to achieve your goals.
Our list of open source materials, found here, includes titanium, various types of stainless steel, ULTEM, PEEK or others. We have the tough materials required for your fixture application.
