Selective Laser Sintering an overview ScienceDirect Topics

Selective laser sintering (SLS) is a technology similar to 3DP, with the difference being that a high-intensity laser (usually a CO 2 laser) is used to selectively fuse the polymer powder. SLS thus avoids any organic solvent and addresses some of the drawbacks of 3DP. 111 SLS minimizes the use of excessive polymer powder, making it one of the most convenient SFF technologies for the
