e-Manufacturing means the fast, flexible and cost-effective production of parts directly from electronic data, which can include rapid prototyping, rapid tooling, (spare) parts on demand etc. Especially interesting is the direct manufacture of end-use parts. In this paper, recent case studies will be presented showing commercial e-Manufacturing projects including small production batches and mass customized series production from various industrial branches. The paper also discusses the relevance of several recent technological innovations in laser-sintering for e-Manufacturing, especially how increasing the productivity of machines and process chains has increased the range of applications which are cost-effective using laser-sintering. Case studies include: small series production (up to a few thousand p.a.) of products such as mechanical compon ents directly by laser-sintering, and how this can improve economics as well as reducing risks; mass production of customer-specific (mass customized) shells for hearing aids, directly by laser-sintering, and how this improves product quality, customer satisfaction and economics; optimized tooling concepts for production of up to millions of products using laser-sintered tooling.
