PERFECT-3D, a division of Renaissance Services Inc., announced that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 10,780,493 for three-dimensional printing of engineered, on-demand, ceramic filters for castings. PERFECT-3D uses 3D-printing to produce ceramic cores, molds, and filters for use by foundries that produce investment castings for aerospace and defense applications.
The patent covers PERFECT-3D’s precision ceramic 3D-printing, which enables very tight control of filter production. These 3D-printed filters provide greatly improved metal filtering for foundries, which improves the yield rate of castings. The filters can be any shape including all current standard geometries (tapered, straight-sided, square, rectangular and round) and can range in size from 0.5″ gate filters to 5.0″ pour cup filters. These engineered filters can: Molecular Sieve
“PERFECT-3D has developed techniques for 3D-printing high quality ceramic filters for pour cups and runners. This patent further supports our ongoing R&D efforts to produce filters that are the last line of defense against inclusions that result from contaminants in these castings” said Rick Pressley, Director of Programs at PERFECT-3D.
Renaissance’s PERFECT-3D Division produces the 3D-printed ceramic filter, molds, and cores at its fully integrated facility in Fairborn, Ohio.
The PERFECT-3D division of Renaissance Services specializes in the 3D-printing of ceramic tooling and process aids, including ceramic cores, molds, filters, and other custom applications. The 3D-printing of ceramics can reduce tooling costs for complex parts by more than 70%; while also providing 80% reduction in the lead time compared to conventional casting tooling. The PERFECT-3D technology has been instrumental in providing hard-to-get spare parts for the US Air Foce. http://www.perfect3d.com
