Thermoforming is a popular manufacturing process that involves heating a plastic sheet and forming it around a mold to create a specific shape. One of the key aspects of thermoforming is creating tools that can be used to form the plastic sheet.

In a previous article, we looked at the different technologies used to fabricate thermoforming tools, as well as their main advantages and applications. In this guide, we will explore how SLS 3D printing can be used to create high-quality thermoforming tools.

What is SLS 3D printing?

Selective Laser Sintering (SLS) is a 3D printing technology that uses a high-powered laser to fuse small particles of plastic powder together. Unlike other 3D printing technologies, SLS does not require any support structures, as the powder acts as its own support.
