Guidelines

Step by step for the best result
3D printing is known for its unprecedented design freedom. Still, we would like to offer you some guidelines and ‘best-uses’ to avoid possible disappointments, improve quality and reduce costs. For you, and thereby ultimately for us as well.

STARTING POINT

Export a .stl file from your CAD software. Making a parallel to conventional printing, this is a kind of .pdf file for 3D models. This is the file you send us through our order form and we will make a quotation a.s.a.p.

Translation

Our software translates your .stl file into layers. Subsequently it calculates the contours, grids and if needed the supports. This enables complex and moving parts being printed in one run.

Layer thickness

Depending on the chosen print quality, the models are built up out of layers varying from 0,33 to 0,12 mm each. This leads to some visible layering on the surface of the product, especially on facets and radii. By finishing the product this can be eliminated.

Minimum dimension

The minimum layer thickness also suggests a minimum ‘printable’ dimension. As a rule we give a minimum dimension of 20 x 20 x 20 mm. The theoretical minimum wall thickness is 0,81 mm, to be on the safe side we advise a minimum wall thickness of 1,04 mm.

Maximum Dimension

The maximum dimension of parts, allowing them to be printed in one run is 600 x 900 x 900 mm. If you have a larger product it can be produced in parts that will be connected by gluing or ‘press-fits’.

Moving parts

Compiled products can be assembled in one run. The theoretical minimum distance of the moving surfaces is 0,178 mm, again, to be on the safe side we work with a minimum distance of 0,6 mm. For ‘press-fits’ we advise 0,127 mm, for ‘slip-fits’ 0,254 mm.
