SLS
SLS is a great solution for rapid prototyping of functional polymers because it offers a high degree of design freedom and accuracy. It produces parts with consistent mechanical properties which means it can be used to produce parts that are very close to end-use quality.
Advantages
- The most widely used SLS material is PA200 (Nylon 12 white)
- Since SLS requires no support structure, parts with hollow sections can be printed easily and accurately.
- Taking advantage of the whole build volume is very important when printing with SLS, especially for small batch productions.
- It is possible to alter the internal structure of a part. (solid, sparse)
- Single SLS parts can be printed as large as x670 x y360 x z560mm.
- The appearance of SLS 3D printed parts can be produced to a very high standard using various post-processing methods such as dyeing, spray painting and machining.
Applications
-
Mommoth model
-
Lampshade
-
Honeycomb structure
-
Architectural model
-
Gear
Printing Process
SLS is an additive manufacturing technology that uses a high-power laser to sinter small particles of polymer powder into a solid structure based on your 3D model.
The entire cross-section of the component is scanned, so the part is built solid. After printing, the parts are fully encapsulated in the un-sintered
powder.
When the print job finishes, the part will be buried in the powder build chamber at the end. The unfused powder remains in place during post-processing, eliminating the unused powder. The fused part will stay attached to the build plate.
