A framework for mapping design for additive manufacturing

Design for Additive Manufacturing (DfAM) is a growing field of enquiry. Over the past few years, the scientific community has begun to explore this topic to provide a basis for supporting professional design practice. However, current knowledge is still largely fragmented, difficult to access and inconsistent in language and presentation. This paper seeks to collate and organize this dispersed but growing body of knowledge, using a single and coherent conceptual framework.  >> Download PDF

Reaction Injection Molding (RIM) Molds with HP Multi Jet Fusion Technology

Reaction Injection Molding (RIM) technology is widely used in the manufacturing of low-volume, large plastic parts (machinery covers, medical devices covers, etc.) in a variety of formulations and densities, using polyurethane as the material.

The process involves the injection of two compounds – polyol and isocyanate – that react with each other to form polyurethane. Polyurethane-curing chemical reactions that occur inside a RIM mold normally take place at low temperatures and pressures, comparable with the conditions of plastic Injection Molding. These low-pressure and -temperature working parameters make HP Multi Jet Fusion (MJF) materials very suitable for RIM mold manufacturing.   >> Download PDF
