What is the difference between 3D printing and SLS?

SLA, or stereolithography, is a method of 3D printing that utilizes a laser and resin. Unlike digital light projection (DLP), which uses a projector screen, SLA is distinguished by the use of a single laser directed at particular points to cure the resin and solidify a pattern.

What is better SLA or SLS?

If feature definition is a consideration, SLA is generally better able to produce small and well-defined features. There are also high-resolution SLA systems designed for smaller parts. The definition of small features with SLS is slightly hindered by the powders grainy surface appearance.

Is SLS 3D printing expensive?

Traditionally, the cost of SLS 3D printing has been cost-intensive for a number of reasons. First, the 3D printers themselves are expensive because of the integration of high-quality lasers and complex configurations. Most systems have also been costly to use and maintain because they require highly trained operators.

What is the material used for SLS process?

The most common material for selective laser sintering is nylon, a highly capable engineering thermoplastic for both functional prototyping and end-use production. Nylon is ideal for complex assemblies and durable parts with high environmental stability.

What are different types of materials available for the SLS system?

Commercially-available materials used in SLS come in powder form and include, but are not limited to, polymers such as polyamides (PA), polystyrenes (PS), thermoplastic elastomers (TPE), and polyaryletherketones (PAEK).
