Selective Laser Sintering (SLS) and Multi Jet Fusion (MJF) are both additive manufacturing technologies used to create 3D objects from powder in multiple materials. However, SLS is considered an older technology compared to MJF, as it was developed in the 1980s, while MJF is a more recent advancement in the field, introduced by HP in 2016.
The technologies are very similar; however, the key difference between SLS and MJF 3D printing technologies is the heat source and material used to fuse the powder material into parts. SLS production uses a laser, whereas MJF uses agents and heat lamps. SLS does have the benefit of offering materials such as carbon fibre. At Get It Made, we solely use MJF because of its excellent print quality and low total production cost.
