There are various 3D printing techniques that manufacture products. The production methods consist of depositing and curing material layer by layer. This is possible through the use of lasers, a liquid binder or, for example, UV lamps. The results of the techniques are therefore very diverse.

Commonly used 3D printing techniques:

Selective Laser SinteringSLS
Digital Light Processing DLP
Selective Laser MeltingSLM
Fused Deposition ModelingFDM

SLS 3D printing at Oceanz

At Oceanz we work with professional 3D printers that print with the SLS technology. SLS stands for Selective Laser Sintering, a widely accepted technology for manufacturing nylon products. How does SLS 3D printing work, what are the advantages and what can you do with it?

What is Selective Laser Sintering (SLS)?

SLS is a printing technique where objects are built up layer by layer by melting powder with the help of a laser. A layer of 0.1 mm plastic powder is dosed onto a powder bed. During the process, a layer of powder is placed on a different layer of powder. With each layer, the powder is locally melted (sintered) by the laser. This hardens the powder and eventually creates a complete object in 3D. After the process and cooling of the entire powder block, the product is removed from the building volume and the excess powder is removed. 3D printing is therefore a sustainable technique. The waste materials are kept to a minimum and the material is reused (zero / less waste).

Advantages 3D printing SLS

  1. 3D printed models in SLS are strong and of a very high quality
  2. Ideal technique for making functional products or good-looking vision models
  3. A suitable technique for manufacturing well-functioning prototypes
  4. Small production series are possible with SLS as 3D printing technology
  5. SLS-printed models are very suitable for Post processing (colours, coating, lacquering)
