SLS

SLS – Selective Laser Sintering

Selective laser sintering, or SLS, is used where the functionality and durability of the part are important. By choosing different materials, you can get parts with extreme flexibility, rigidity and resistance to aging. SLS is a additive manufacturing method where we create the part directly from your CAD data without first producing a tool.

Advantages

SLS is the best option if you need your product to be made from a durable material. By choosing different materials, you can get parts with extreme flexibility, rigidity and resistance to aging.

SLS – Technical information

SLS is a additive manufacturing method where we create the prototype directly from your CAD data without first producing a tool.
By means of various types of post-processing, design models can be produced, for instance. In this case the part is polished and lacquered to make it as similar to the end product as possible. We add different surface textures, graphics, print and colours.

EOS End-To-End Production Partner

Prototal Industries is a proud to be the first member in the world to join EOS End-to-End Production Partner Network.

The Network is designed to connect companies of all sizes in search for high quality serial additive manufacturing (AM) support with selected, certified EOS partners.

Guidelines

Grainy surface.
Risk of warping on large flat areas.
Uneven wall thickness can affect accuracy in the form of non-linear shrinkage.
Threads of less than M10 are not recommended directly in the plastic. For smaller threads and strengthening purposes, HeliCoil or Trisert thread repair inserts are a good idea. In the case of HeliCoil, please inform us before we manufacture the parts so that we can enter the threads directly in the CAD model and fit the thread inserts later on. External threads of less than M10 are not recommended. These are machined into the finished part.
For surfaces with an angle of less than 20° to the X/Y plane, distortion due to the layer effect (stepping) can be marked. The steeper the angle, the better the surfaces.
To obtain a press fit, ensure a gap of 0.1 mm (average particle size X2). This fit will be slightly looser on wear (particles work loose over time).
To obtain moveable parts printed in a workpiece, ensure a gap of 0.4 mm in X/Y/Z. It is also important that loose powder in the gap can be removed.
Working hinges can be easily achieved in polypropylene. However, it is important that one takes care when first opening the item to which they are attached, so as to ensure longer service life of the hinge. Hinges can also be made from PA2200, but their service life tends to be shorter.

Customer case – Anatomic Studios

A completely new dimension in prosthetics!

At Anatomic Studios, they saw more or less immediately that this was a product made for 3D printing. Total freedom in principle in terms of the design of patterns and skin, with no extra costs for complex geometries. The possibilities of additive manufacturing are exploited pretty much to the full.
