Correlation of Process Parameters with Mechanical Properties of Laser Sintered PA12 Parts [PDF]
Advances in Materials Science and Engineering, 2017 Selective laser sintering (SLS) is an additive manufacturing technique that enables the production of customized, complex products. SLS has proven itself a viable prototyping tool and production method for noncritical products. The industry has picked up on the potential of SLS, which raised the question whether it is possible to produce functional ...
