What is the main difference between SLS and SLM?

The main difference between SLS (Selective Laser Sintering) and SLM (Selective Laser Melting) is the material they use and how the material is processed.

● SLS uses a laser to sinter polymer powder, bonding the particles together without fully melting them. It’s suitable for creating plastic parts.

● SLM also uses a laser but melts metal powder completely, resulting in fully dense metal parts. It’s used for applications requiring metal components.

Both processes build parts layer by layer, but SLM is typically used for metal alloys, while SLS is used for thermoplastics.
