DESIGNING FOR 3D PRINTING

There are many CAD and modelling softwares that can be used to do create your own

designs and prototypes. However, there are some tips that can help you in printing your

design just how you have designed it in CAD:!

1. Modify your CAD design to make it easier to remove your 3D print from the printing

plate by adding a notch.

2. Avoid printing support material by orienting your print through the Edit feature in

MatterControl.

3. Use cooling towers or extra prints to get optimal print time and cool time per layer.

For very intricate and small prints, it is optimal that each layer has enough time to cool

before another layer is added on top. With the hot end extruder so close to each layer in

a small printing space, the layers are likely to start warping because they have not had

the chance to cool properly. If you place another print or a column printing away from

your print, it has enough time to cool and you should not experience as much warping.!

4. Optimize the quality of your CAD ﬁle to match your printer resolution. Your 3D model is

essentially a mesh with many faces that gets sliced into many layers - if you would like a

completely smooth print, make sure that your mesh is ﬁne enough in your CAD ﬁle.!

5. Pick the appropriate inﬁll. In MatterControl, you are able to pick many diﬀerent inﬁlls

and a range of 0-100% inﬁll. For prototyping or your ﬁrst draft print, we suggest a lower

10-20% inﬁll to reduce the amount of plastic you use and the time it takes to print. For a

strong, usable part, we suggest 60% and higher. Note that the smaller your inﬁll

percentage, the more top solid layers are needed to achieve a solid top layer.!

6. Adjust tolerances. If you are using nuts and bolts in your ﬁnished print, you have to

make sure that they ﬁt properly once printed. Eg. for a 3 mm bolt to slide through the

printed part, size your hole to 3.5 mm in your CAD software. For a tap out, undersize to

2.7 mm (and a minimum of 3 perimeters when slicing) for a 3 mm bolt.!

7. Plan for multi-materials printing with your dual extruder. In the Edit settings in

MatterControl, you are able to select which parts you would like to print with which

extruder by selecting Ungroup where the software will recognize diﬀerent solid parts in

your print that can be selected and printed on its own or with your second extruder.!

8. Interlocking designs - allow for enough tolerance. Although the printer is highly

accurate, the tolerance can depend on your ﬁlament and the printing temperature.

Measure your ﬁlament using calipers in several places and input the “corrected” ﬁlament

diameter in the Filament slicing settings. You can also change the Extrusion Multiplier

values to make sure your hinged parts have enough clearance and are able to print with

the negative space in between the hinges in order to print a working part.
