Growing Pains Casting Study Now Available

With the support of the Santa Fe Symposium and MJSA Journal, another is a series of studies on the casting of 3D Printing materials and CNC milling wax has been published. The 2005 white paper “Getting Up to Speed” found that hygroscopic expansion was one of the reasons that light curing materials (photopolymers) were so problematic for investment casting. That study fell short however in addressing residual ash content and thermal expansion which was the subject of the new 2008…
