You might need extensive training for traditional SLS 3D printers to prepare them. Preparing the 3D printer depends on the type of printer you are using. After preparing the CAD files, send the instructions to the printer. Specify the printing settings, orientation and arrangement of models, estimates of print times, and slicing. Below is a step-by-step guide on how it works:ĭesign a CAD file using CAD software and export it in a 3D printable file format (e.g., OBJ or STL).
SLS 3D printing is a unique technology known for accuracy, precision, and quality 3D printed parts. Consequently, it has a widespread adoption like Stereolithography and Fused Deposition Modeling Process even though it is expensive and complex. The method is a powder bed fusion technology (i.e., it involves using thermal energy to fuse regions of a powder bed selectively) and was patented in 1980.ĭue to massive improvement in the method, it is suitable for many materials such as plastics, ceramic, and glass. Brief History of SLS PrintingĬarl Deckard and Joe Beaman, student, and professor of Mechanical Engineering at the University of Texas, developed the SLS AM technology. Most businesses prefer it due to its high precision and suitability for making geometrically complex products. SLS printing is a technology that involves fusing powdered materials using a laser to form a rigid 3D model.
