Embossed and engraved text
If you plan to put some TEXT embossed we recommend adding a
minimum line thickness of 0,5-0,6 [mm] and a depth of 0,5 [mm].
Use a bold sans-serif font for readability, such as Arial Bold f.ex.
Minimum feature size
The minimum feature size for printing with SLS is 1 [mm]. If your
feature is a thin wire connected on both sides, you can go slightly
thinner to 0,5 [mm], otherwise, we recommend at least 0,8 [mm]
thickness.
Functional gap - moving or interlocking parts
A powerful feature of SLS is that you can print moving parts in one
go. You should keep at least 0,2 [mm] clearance between
elements. We recommend keeping at least 0,5 [mm] if you are the
beginning user.
Escape holes
Sometimes you have to increase your clearance or create extra
escape holes for the powder to get out f.ex when you have moving
parts like hinges over a long distance. We recommend making in
the model at least 4 [mm] diameter for one escape hole, 2 [mm] for
two or more.
