Is 3D printing different in space

3D printing service: Instructions / preparation / request

The step from a virtual model to a print-ready file requires cleanly structured 3D data:

In principle, 3D data is required for 3D printing. It will be aclosed (waterproof) volume model provided. All individual components of a model must be described as complete bodies. All bodies should be connected to one another without any gaps and any overlapping of surfaces must be avoided. Movable structures must have a constructed gap of approx. 0.2 mm between the individual elements.

In the FDM / FLM process, the following applies to minimum wall thicknesses:
approx.1 mm (The limiting element is the track / deposit width of the melted material at the nozzle outlet)

In the 3DP process, the following applies to minimal wall thicknesses:
Non-load-bearing structures in the model: at least 2 mm
Load-bearing structures in the model: at least5 mm

The one developed by 3D Systems, which is very common in rapid prototyping, is suitable for monochrome models STL format (* .stl), which can be output by almost any 3D CAD program. If color information or textures are also to be transmitted, that is VRML format (* .wrl) most common.
There are many other 3D data formats that can be converted into a suitable format if necessary. As an alternative, you can always send us your data in STEP format (* .stp or * .step) available.

When outputting the data in one of the above formats, make sure that the tolerance setting (tessellation) is suitably precise, a good value is usually: 0.01 mm.
