HotEnd Works is a rapid 3D prototyping company specializing in 3D printed plastic and ceramic prototypes. The firm has developed a 3D Printer capable of printing advanced materials, such as Alumina Ceramic, using a proprietary highly advanced thin film processing technique capable of manufacturing advanced ceramic components utilizing a unique PSD technology unrivaled in material performance. The process allows not only use stock ceramic materials but enables use of proprietary advanced ceramic blends that can be incorporated into the PSD technology. Founded to address a market gap in advanced material 3D printing by enablng advanced materials, such as ceramics more accessible to the engineering / design community. HotEnd Works' 3D printer, the HDfab, uses proprietary high density deposition technology. This technology will allow for high performance 3D printed parts that will drive the cost of advanced material parts down, while performing at the level of today's traditionally manufactured parts. The 3D printing system will also reduce lead times from several months to days. Serving the aerospace / defense, general industry, and medical markets, the high performance nature of the materials produced from HotEnd Works' proprietary process has garnered the interest of several major government institutions. Several partnerships have been formed and current investigation into the feasiblity of replacing traditionally manufactured parts with HDfab 3D printed parts is underway. The company has completed successful ballistic testing with the Army Research Lab in Aberdeen Proving Ground, Maryland. HotEnd Works' materials were nearly identical in performance compared to traditionally-manufactured parts.
