L
ike all production processes, 3D printing has
constraints which are to be considered during
the design phase in order to make high-quality,
functional, and beautiful objects. I love seeing
people make their own designs to fulfill their
specific needs and desires, so I’ve collected many
of these considerations to help you hit the ground
running!

BILLIE RUBEN is a life-
long maker, ex-moderator of
r/3Dprinting and current admin
of the largest 3D printing Discord.
Billie enjoys collecting skills
and sharing them with others,
particularly with 3D printing. You can support her

This infographic is part of a series of 3D
printing poster guides that I have produced.
You can access full-resolution copies of these
guides for free so you can print your own; I
also sell prints through RedBubble if you’d
like to support me making more. Links for
both can be found here: billieruben.info/shop
If you get stuck with a design, the
3DPrinters community on Discord (discord.
gg/B4tp8MH), which I help run, is happy to
help you out.
Happy Printing!
A slit, bolt, and trapped
nut can be added to holes
to allow them to
be tightened around
another part.
Use software that
makes manifold objects
(without tiny gaps or
reversed faces), to avoid
slicing errors.
Compliance can be
added to parts to enable
flex, which enables
push-fitting parts.
Diagonal ribs can be
added to support/enable
a roof to bridge between
them. Can be beneficial
inside a model.
Complicated or fitted
parts of an overall print
can be isolated and
printed to test for fit.
Sacrificial, perpendicular
ribs can be added to
support overhangs during
printing.
Reduce the risk of a print
warping up from the bed
by rounding out or adding
mouse ears to corners.
Text looks best when
indented into a vertical
surface. It reduces
overhangs and has
better resolution.
Curves look good with
an axis in the Z direction,
but due to the layering
process can look very
poor in the X/Y.
Due to the planar layering
of most 3D printers,
print orientation has a
significant impact on
strength.
