The standard layer thickness range is 0.05 to 0.15mm in SLS 3D printing. The laser will scan the upper layer of the part that the slicer defined above the powder bed’s top surface. The laser power is set accurately to attain a sintering depth equivalent to layer thickness. The printing process itself is ingenious and simple. It then makes way for speedy 3D printing. Through this, the laser’s heat energy is just used in sintering. The build chamber’s powder content is preheated before the start of the printing to just under its melting point.

There is also the need to calibrate the galvanometers or the mirrors directing the laser beam along the preferred printing path. Aside from this, professional operators also conduct several preprint CAD checks to ensure any loopholes won’t compromise printability. Before the actual printing process starts, several checks are conducted to guarantee the smooth flow of printing. The powder bed or build chamber is filled to the right level and with the suitable material. The SLS 3D printers are complex machines needing care and training. The software also integrates user-defined settings like resolution, laser power, and layer thickness that serve as the defining factors for the quality of the final build. This is also the stage where the software forecasts critical data like material consumption and print time. ![]() RELATED: What is 3D printing? A beginner’s guide It generates commands called G-Codes that the controller of the printer can interpret in terms of the laser’s scanning motion. STL is the most popular file format used these days. The slicing software will then get the CAD file ready for 3D printing. The final model will then be transferred to the built-in user interface of SLS printers or the slicing software in the file formats that suit 3D printing. Several steps are involved in SLS 3D printing, and these are the following: Preparation of the CAD modelĮverything begins with the 3D modeling design firm creating a CAD model of the specific part that will be printed. The sought-after material qualities of SLS 3D printer parts are promising factors for both product developers and manufacturers. They also differ in manufacturing accuracy, cost, laser power, and laser type, which can be CO2 lasers, diodes, fiber, or others. The technique is famous for its viability for rapid prototyping and manufacturing functional parts. RELATED: 3D Printing technologies for modeling and prototyping It is known as a sintering instead of a melting process. SLS 3D printers also come in various build volumes that range from large-scale industrial to desktop. Once heated, these particles don’t melt as they merge. SLS 3D printing services utilize heat energy through a guided laser to sinter layers of raw material particles into a durable and robust build. ![]() With a whopping value of $13.84 billion, the additive manufacturing industry is one of this modern era’s fastest-growing manufacturing technologies. SLS, or Selective Laser Sintering, is among the breakthrough 3D printing technologies that catapulted its quick rise to popularity and paved the way to wide-scale adaptation across various industries. This article is a comprehensive guide to SLS 3D printing services for companies: What is SLS 3D printing?
