10. Continue to press tight, against the shop
head as it cools, making sure it doesn't
relax away from the mounting point.
Don't apply force to the assembly until
both the rivet and the parts being as-
sembled cool to room temperature.
Two Materials, Two Ap-
proaches to Finishing Tech
ABS and PLA plastics have very different phys-
ical properties. ABS is printed at a higher tem-
perature (typically 215-235°C), is more
durable and flexible, and dissolves in industrial
solvents like acetone. PLA can print at lower
temperatures (starting at 180°C), wears down
faster, can be brittle or shatter, and won't dis-
solve in acetone. (The chemicals used to dis-
solve PLA are highly toxic.)
Hold in place until cool as seen here:
If you'd rather use a soldering iron
than a heat gun, find a brass tube
(
Figure 13-17
) that fits snugly over
your iron. Use the brass tube to
work the plastic, and keep your sol-
dering tip clean. Make sure to clean
your tube thoroughly so the plastic
doesn't stick to the brass.
1. Installation of a hinge rivet follows the
same procedure, except at the very end.
After pressing the shop head, move the
parts gently as they cool to ensure that
the joint has enough play for the hinge
to open and close easily.
In the completed assembly, the two
black ABS plates can spin easily on the
hinge without coming free.
