SLS 3D printing - Selective Laser Sintering

Selective laser sintering (SLS) is a state-of-the-art additive manufacturing technology / 3D printing technology


Selective laser sintering offers several advantages over traditional manufacturing methods, including the ability to create complex geometries with high precision, excellent mechanical properties, and the freedom to use a wide variety of materials. This makes it a popular choice for producing prototypes, custom parts and production runs in various industries, including aerospace, automotive, healthcare and consumer goods.

An SLS 3D printer uses a powerful laser to fuse together tiny particles of pulverized material to create intricate three-dimensional objects. Compared to other technologies, the advantages of SLS 3D Printing are compared to FDM and SLA technology.

Advantages of SLS

  • Can create extremely complex geometries, no support structures needed
  • Parts created with SLS Technology have higher strength, comparable to a molded part
  • Objects created with laser sintering are very strong, it is not noticeable that the part is made on a 3D printer
  • Multiple parts integrated into the same model can be easily created. For example, a model consisting of two parts that fit together. No retrofitting required
  • Sintratec S3 has support for metal prints called cold fusion
  • Has high precision and tolerances within about +- 0.5%

Limitations:

  • Material and color choice, models can be colored afterwards

For more info expand below:

  • Powder-based material:
     SLS starts with a layer of powdered material, usually plastic powder of, for example, polyamide (nylon), plastic, metal or ceramic. This powder also acts as building material and support structures for the object to be printed.
  • Selective fusion
     A high-precision laser scans and fuses the powdered material according to a digital blueprint of the object being created. The laser beam traces the cross-section of the object on the powdered layer and causes the particles to fuse together at precise points.
  • Layer by layer construction :
    After a layer is completed, the build platform is lowered a fraction of the layer thickness, and a new layer of powder material is spread over the previous layer. The laser beam then fuses this new layer with the previous layer. This process is repeated until the entire object is constructed, layer by layer.
  • Finishing :
    When the printing is finished, the models in the build chamber need to cool down. The printed object is then carefully removed from the remaining powder in a material handling station (MHS). Some of the remaining powder can be recycled
    for future printing.

  • Further finishing
     When the models are cleaned, the parts need to be cleaned from traces of powder. It is done with the help of a blasting station.
  • Alternative finishing
    Then, depending on the wishes, the models can also be finished with various Finishing techniques such as grinding, polishing or painting can be used to achieve the desired surface.

  • Polyamide (Nylon / PA12): The most used SLS 3dprinting material on the market, used for parts created in industry and production using SLS printers. PA12 withstands is hard, slightly flexible, melts at 185ºC

  • Polyamide 12-GF (Glass filled) The nylon material is combined with glass, providing higher strength, a stiffer and more durable part, and slightly higher heat resistance.

  • TPE (TPU): Sintratec TPE powder is an elastomer that creates flexible, rubbery parts. The material is impressively stretchable and withstands breakage of up to 448%. TPE is an industrial grade material well suited for applications that require a high degree of ductility. (That is, the material can be stretched/bent without the material becoming defective or breaking)
  • Other materials: Sintratec AMP systems can be used with most materials on the market but may require optimization. Contact us for more info.
  • We use Sintratec S3 and MCU220 which can handle models up to ⌀220x400mm
  • Sintratec S3 & S2 can also be used with MCU160 which can handle ⌀160x400mm
  • The Sintratec Kit has a construction volume of max. 110x110x110 mm
