Data - preparation

Required file format for all our 3D-printers:

.STL

A 3D-printer manufactures an object based on a 3D-model. This model can be designed in any 3D-design or CAD software you like. It is important to export your design in the format .STL, which is compatible with all our 3D-printers and almost every 3D-printer out there. The .STL-export of your model converts the actual shape into a shape composed of triangular elements. Increasing the quality settings of your export means that more triangles are used to approximate the original design. In the picture below you can see a low and a high quality export with their resulting prints. Using a low quality .STL file will result in a print with significant deviations. Whereas the print result of the high quality export is quite similar to the original CAD design.

Print Technologies


FDM

Fused Deposition Modeling

Image

This type of 3D-printer heats up a plastic filament in a nozzle until it melts. By moving the nozzle and extruding the materail it creates a model layer by layer

If you wish to know more about how FDM printing works check out this video.


SLA

Stereolitography

Image

This type of 3D-printer uses a liquid resin as a material. The base is immerses into the resin where a UV laser then hits the material and solidifies it. This is done for each layer until the model is finished.

Materials

Each 3D-printing technology has different advantages and disadvantages, as well as there are various materials with different properties available for each technology. To give you an overview and help you selecting the right material and technology for your needs, we listed our available materials, ranked their properties, and quantified some important characteristics.
