Direct Metal Laser Sintering [PDF]
Laser Technik Journal, 2015 AbstractA few years ago, 3D printing and additive manufacturing (AM) were next generation technologies and well known as methods for rapid prototyping. Less rapid manufacturing applications were on the market (e. g. manufacturing of dental crowns and bridges).

, 2023 Existing laser sintering systems have several advantages over alternate additive manufacturing technologies but suffer from limitations inherent to the use of a single, self-contained powder bed. This powder bed design limits the ability of the machine to print multiple materials in a single print cycle, obscures the part during printing which can lead

Optimization of selective laser sintering process conditions using stable sintering region approach
eXPRESS Polymer Letters, 2021 The optimization of process parameters represents one of the major drawbacks of selective laser sintering (SLS) technology since it is largely empirical and based on performing a series of trial-and-error builds.

Relating Operating Parameters between SLS Machines which have Different Scanner Geometries and Laser Spot Sizes [PDF]
, 1992 As the number of SLS machines in operation increases, the opportunities to share operating parameters with other SLS operators also increases. However, if the machines are not identical down to the spot size of the laser beam, the quality of parts ...
