What is SLS?

Selective Laser Sintering (SLS) is a powder-based 3D printing technology. It makes use of a high powered laser that selectively scans a thin layer of powder and sinters the small powder particles together to form 3D object, layer by layer.

Unlike most other additive manufacturing technologies, SLS does not require any form of support as the leftover unsintered powder acts as self supporting material. Thus, extremely complex geometries are made possible. 

The technology is a great choice when 3D printing functional prototypes as SLS printed parts are robust and will not become brittle over time. In fact, durability of parts created with SLS technology is on par with those produced through traditional manufacturing methods such as injection moulding. 

In comparison to MJF, SLS also has more material options.

Materials

SLS Buckle

PP

Short for Polypropylene, PP is a thermoplastic “addition polymer” made from the combination of propylene monomers.

SLS PA12 (White)

PA12 (White)

White PA12 material for slightly more translucent parts. High strength and stiffness and various finishings possible.

PA12 Grey

PA12 (Grey)

A Polyamide 12 powder (nylon based compound) with good mechanical properties and excellent surface resolution.

TPU Flexa Black/Grey

TPU material for producing flexible parts. Similar properties to rubber, suppresses hits and shocks well.

Glass-Filled Nylon

Glass-Filled Nylon

Glass filled Nylon (SLS) contains glass particles that give parts high stiffness and improved thermal and abrasion resistance over standard Nylon.

3D Printing Processes

FDM

FDM

Short for Fused Deposition Modeling, FDM is one of the most commonly adopted additive manufacturing technologies today due to its low cost and efficiency.

SLA

SLA

Great for products that require a smooth finish and high accuracy. SLA is also a popular choice for creating prototypes for clear parts, including bottles.

Polyjet

Polyjet 3D Printing

Capable of printing multiple materials from flexible to rigid in one part. 3D prints at a high speed, with extremely high accuracy and a smooth surface finish.

SLS

SLS is a powder-based 3D printing technology suitable for building parts that require high durability and complex geometries as it does not need any form of support.

MJF

MJF 3D Printing

Similar to SLS, Multi Jet Fusion also utilizes powder to 3D print objects. One advantage is that parts produced by MJF are stronger and more precise compared to SLS.
