Rapid-Manufacturing-Verfahren, generell Additive Fabrication-Verfahren sind Fertigungsverfahren, die das Ziel haben, vorhandene 3 D CAD-Daten möglichst ohne manuelle Umwege oder Formen direkt und schnell in Werkstücke umzusetzen.Rapid prototyping or rapid manufacturing process, generally additive fabrication process are manufacturing processes that have the goal of existing 3 D CAD data as possible without manual detours or forms directly and quickly to convert into workpieces.
Unter den Rapid-Prototyping-Verfahren gibt es zwei Gruppen von Verfahren. Bei einer Vorgehensweise wird auf die gesamte Oberfläche aufgetragenes Material selektiv gebunden (Selektivverkleben). Stereolithographie und Selektiv-Laser-Verfahren (SLS) sind bekannte Verfahren, die nach diesem Prinzip arbeiten. Bei der anderen Verfahrenstechnik wird das Material selektiv abgelagert und gebunden (Selektivauftragen).Under The rapid prototyping process has two groups of procedures. An approach will affect the entire surface applied material selectively bonded (selective bonding). stereolithography and Selective Laser Techniques (SLS) are known methods that work on this principle. In the other process technology is the material selectively deposited and bound (selective application).
