Rounded edges

In short

3D-printing comes with a lot of design freedom. You can add angles and curves without making the production process more costly or complex. We encourage you to add as many fillets as possible.

Be sure to add fillets

Adding generous fillets to connections is crucial to increase structural support. It is important to make fillets as large as possible to increase the amount of surface area involved in a connection. Another way to achieve this is drafting extrusions outwards.

Sharp corners and edges often get softened during post-processing, so adding fillets can also make your parts more predictable and accurate.

Curved surfaces

Different print orientations

Complexity is free, that includes organic shapes and curved surfaces. However, there are a few considerations when creating these shapes.

The print direction is critical to the quality of your parts curves. Curves in the XY-plane will be the most accurate. In the Z-direction, the accuracy is linked to the layer height of the build. SLS printing is a very precise method of 3D-printing. However, on parts that have an angled or curved surface in the Z planes, you will still be able to see some layering. Shotpeening will get you a smooth finish on these surfaces. If a specific dimension or curve it critical to your part, please indicate this on the technical drawing so we can take it into account when setting the print orientation.
