brush strokes to cover a surface with paint.
And in practice, it works! The longer a model
would take to print with the Normal settings, the
more time you can save.
Here’s how to do it:
1. Click over to PrusaSlicer’s Print Settings tab
(Figure
B
).
2. Click the Expert button to expose additional
settings.
3. Select the Advanced category from the list on
the left side of the window.
4. In the Extrusion width group, set all the
available values to 0.65mm.
5. Then, return to the Plater tab to slice the
model, export the G-code file, and move
the file to your printer for printing.
NOTE: If you use Cura, search for Line Width
and make the changes there (Figure
C
). This
technique should work in any slicer which gives
you control over extrusion width. Simplify3D,
IdeaMaker, SuperSlicer, and even the browser-
based Kiri:Moto slicer have settings for line width,
though it sometimes goes by a different name.
For the Neutron Tube model, the time
estimate was reduced from about 19 hours
to 14 hours. And when printed, the model
sliced with unmodified settings finished in
about 18 hours, while the model with the
wide extrusions finished in about 13 hours —
about 5 hours faster! I couldn’t see much of a
difference in quality or precision between the
two, either (Figure
D
). The hinged lid and the
threaded ring work equally well on both.
What are the downsides? The time savings
on smaller models may only be a few minutes.
And while I had no issues with the Neutron
Tube, some print-in-place mechanisms may
not work if the moving parts fuse together
during printing. You may also notice small
gaps where the wider tracks meet corners.
But it’s worth experimenting with, and it’s a
handy tool to keep in your 3D printing toolbox
that can save time on longer prints.
