Understanding SLS Printing
SLS is that type of revolutionary technology for 3D prototyping and manufacturing printing. Now, if this entire world of 3D printing is very new to you, doubtlessly a question must be popping up in your mind by now. What is SLS technology and how important is it? In this section, we touch briefly on some basics of the SLS process, its benefits, and common uses before giving you a reason to appreciate it in the present innovation landscape.
What is Selective Laser Sintering (SLS)?
In short, SLS is one type of additive manufacturing process which uses an extremely powerful laser to sinter the powdered material; in this way, solid objects are created layer by layer. The operation in manufacturing with said machine will go on:
- Preparation of Material: A thin layer of powdered material is evenly spread onto the build platform.
- Laser Sintering: It sintered the surface of the powder—that is, information from the 3D model was used to fuse particles in prescribed sections with a laser beam.
- Layering: As one layer nears completion, the platform moves down a bit, and another layer of powder is laid down. This continues until the object is fully built. 4. Cooling and Removal: Once the printing is complete, the chamber cools, and with blowing air around it, the excess powder falls off, revealing your final object.
Advantages of SLS Over Other 3D Printing Methods
SLS offers several advantages that make it a preferred choice for many applications:
- Complex Geometries: SLS can create intricate designs that would be difficult or impossible with traditional manufacturing methods.
