Laser Sintered Injection Moulds, case studies made in Belgium

Rapid manufacturing is a new trend in mould making. Several techniques are used to shorten the production cycle of mould making. Main focus for the presented research were Material Addition Processes (MAP) such as Selective Laser Sintering (SLS) and Direct Metal Laser Sintering (DMLS). Almost 10 years of research shows several trends in this domain. Some industrial cases of rapid manufacturing based injection moulds will be discussed. Main points of interest during the research were the production cost and the obtained dimensional accuracy and surface roughness. Several typical techniques to finish the cavity and the inserts were investigated. A short exploration of conformal cooling channels was done. A short overview of the concerned rapid manufacturing techniques that are nowadays commonly available in Belgium will be given.
