CAD Design Tips
for 3d Printing
Make walls a multiple
of your extrusion line
width for a smooth slice.
If it was 0.4mm use 0.8,
1.2, 1.6, etc.
A thin, sacrificial bridging
layer can reduces
the need for support
material. It is cut away
after printing.
Vertical edge fillets
increase quality by
reducing inertia during
harsh directional
changes.
Equal chamfers always
work (even from below) as
their overhang remains at
a printable 45°.
Filament must be
laid upon existing
material, so avoid steep
overhangs to reduce the
need for support.
Roughly 0.3mm clearance
should be added between
fitted parts using offset ...
