What is laser sintering in 3D printing?

Selective laser sintering (SLS) is a 3d printing process (additive manufacturing) that uses high-powered lasers to sinter, or bind, finely powdered material together into a solid structure.

What is laser sintering process?

The laser sintering (LS) process uses a laser source to provide thermal energy and selectively fuse together particles of a powder material into complex three-dimensional shapes in a layer-by-layer strategy [52].

What is a selective laser sintering SLS 3D printers?

Selective laser sintering (SLS) is an industrial 3D printing process that produces accurate prototypes and functional production parts in as fast as 1 day.

What are the applications of selective laser sintering?

SLS is used in a variety of end-use applications in industries including automotive and aerospace. Considering its robustness and capability to produce highly complex parts, SLS can introduce major time and cost savings for small-run parts that would otherwise require assembly with traditional manufacturing.

How does plastic sintering work?

Sintering of porous plastics is a process whereby various porous materials are fused together, but not to the point where it liquefies, using specific controlled heat and/or pressure applications . The materials used may be most any thermoplastic polymers but polyethylene or polypropylene are more commonly used.

What are the advantages of laser sintering?

Selective Laser Sintering Advantages – Best for producing strong, functional parts with complex geometries. High level of accuracy (though not as high as stereolithography). Doesn’t require supports, saving printing and post-processing time.

What are the pros and cons of selective laser sintering?

S.No.SLS AdvantagesSLS Disadvantages
5.Very fast 3D printing.3D prints are brittle in nature.
6.Robust 3D Printed parts.Post-Processing procedures are difficult.
7.High dimensional accuracy.
8.The cost of printing is comparatively Low.

What is a sintering process?

Sintering is a thermal process of converting loose fine particles into a solid coherent mass by heat and/or pressure without fully melting the particles to the point of melting.

What material is used in selective laser sintering?

The most common material for selective laser sintering is nylon, a highly capable engineering thermoplastic for both functional prototyping and end-use production. Nylon is ideal for complex assemblies and durable parts with high environmental stability.
