Plastics are a versatile type of material, and as a result, there are many ways of manufacturing them. 3D printing is no exception, so let’s explore the different methods.
What is FFF 3D printing?
The FFF process involves extruding a thick string of material, commonly referred to as filament, through a heated nozzle.
The nozzle is mounted on a motion system that moves it around a build area, where the melted filament is deposited onto a build plate. As the material cools and solidifies, the build plate moves down by a fraction of a millimeter layer by layer until the object is complete.
What is SLA 3D printing?
SLA 3D printing uses a UV-curable resin as raw material. The resin is poured into a glass-bottomed container, into which a build platform is submerged.
What is SLS 3D printing?
SLS 3D printing uses a powdered raw material, typically a polymer. The powder sits in a container, where a blade distributes a thin layer of material onto the build area.
