SLS 3D printing

Selective laser sintering (SLS) is a 3D printing process that uses a laser to sinter small particles of powder — typically nylon — to form solid layers. Although the process is mostly used for prototyping, SLS production has increased in recent years, with applications in areas like aerospace, electronics, and consumer goods.

Advantages of SLS include the ability to print without support structures, since the partially printed object is always surrounded by unused powder, while nylon printed parts offer high strength and chemical resistance. The process is primarily used industrially, but some desktop machines ($5,000+) are also available.
