SLS

FAQ

Selective Laser Sintering allows engineers to create prototypes early in the design cycle and use the same machine to produce final parts. SLS 3D printing eliminates the need for expensive and time-consuming tooling required by traditional manufacturing, enabling rapid testing and easy modification of prototypes. This significantly shortens the product development timeline.

– Both are powder-based 3D printing methods, but the main difference lies in the heating method.
– MJF prints usually have a matte finish and are often black because dark solvents absorb heat more effectively; SLS parts are often white and easier to dye, with gray SLS nylon powder being common and having a smoother texture than MJF.

The SLS printing process involves spreading a thin layer of powder on the print platform, then using a laser to sinter the powder in the desired areas. The platform then lowers by one layer thickness, and the process is repeated until the print is complete. After printing, the parts are cooled and the solid powder block is removed to extract the finished parts.

– Produces parts with a matte, fine-grained surface texture

– Minimal layer lines

– High part mobility and mechanical performance

– Does not require support structures during printing

– Some materials offer high temperature and chemical resistance

SLS parts often have a powdery surface that is easy to dye. Various post-processing methods such as media polishing, dyeing, painting, and coating can enhance the appearance of SLS printed parts. Functional properties can also be enhanced with waterproof coatings or metal plating.

SLS is often used for functional parts or product prototypes and small-batch production due to its high design freedom and precision.

The SLS (Selective Laser Sintering) process involves using a high-frequency laser to sinter powder material, fusing it with the previous layer to build a solid structure layer by layer. This process does not require support structures, allowing for the creation of complex designs. The materials used in SLS are typically thermoplastic polymers.
