Tack the seam and let it cool
4. Plug Gaps with Filament
Gaps that are wider than half the width of
your welding filament should be filled before
welding a clean seam. Soften a short scrap
of filament to use as filler, by using the low
setting on a heat gun or by warming it to
100°C on your printer's heated build plat-
form (
Figure 13-10
).
Moving the spinning filament in tight little
circles, widen the melt zone slightly into the
sides of both parts, making a little forward
progress with each circuit, until you've cre-
ated a small spot weld (
Figure 13-8
).
Press the softened filament into the widest
gaps between the two parts, making quick
tack-welds if necessary to pin it in place.
Figure 13-8.
Spot welding diagram
Tack in three or more places along the seam
and let the parts cool. They should be tacked
tight, difficult to separate by hand (see
Figure 13-9
).
