Selective Laser Sintering (SLS)
Selective Laser Sintering (SLS) is a technique that involves using a laser as a power source to sinter (melt together) powdered material. For orthosis manufacture this material is commonly Polyamide-11 and Polyamide-12 nylon.

We currently recommend Selective Laser Sintering (SLS) to our users wishing to manufacture 3D Printed orthoses. |
Fused Deposition Modelling (FDM)
Fused Deposition Modelling (FDM), sometimes referred to as Fused Filament Fabrication (FFF), is a 3D printing process in which a continuous filament of a thermoplastic material is fed through a moving, heated printer extruder head. This thermoplastic material is deposited in specific locations on a growing object as per commands defined by a computer control.

User feedback suggested that thermoplastic polyurethane (TPU) filaments are the most common form of material utilised in this form of printing. |
Stereolithography (SLA)/Direct Light Processing (DLP)
Stereolithography (SLA) and Direct Light Processing (DLP) are very similar as both technologies involve the exposure of a liquid resin to a light source. In SLA the resin is exposed to a laser, whereas in DLP a projector is used. This different in light source results in slight differences to achievable accuracy and surface finishing.
