Design guidelines for DMLS - a technical guide

Direct Metal Laser Sintering (DMLS) is an additive manufacturing technology that is based on melting layers of metal powder using a powerful carbon dioxide laser. The fact that layer-based production processes do not require tooling has led to the assumption that these technologies are free of rules that govern design for manufacture, like draft angles and undercuts.

Whilst DMLS does not have to observe conventional design rules, there are others that do apply to the process, particularly if reducing cost and waste is a consideration. This guide looks at these rules and how they affect the design of parts built using the DMLS process.
