ABS and HIPS

ABS
Acrylonitrile Butadiene Styrene is a commonly used thermoplastic
as it is lightweight and can both be injection molded and extruded.
It has better mechanical properties than HDPE and less brittle than
PLA but handles higher temperatures better for applications such
as extruder and carriages setups without a fan.
ABS is good because it is easier to buy and requires less
force to extrude than PLA as it has a lower coefficient of
friction. This makes its extrusion characteristics better for
small parts, compared to PLA. The downside of ABS is that it
has to be extruded at a higher temperature: Its glass transition
temperature is ~105 °C. ABS is amorphous and therefore has no
true melting point, however 230°C is the standard for printing.
ABS filament adheres well to Kapton tape on a heated build plate.
Compared to PLA, ABS has a longer lifespan, is more impact
resistant, and has a more matte look and finish.
ABS Filament has a high melting point, so it's suitable for machine
or car parts also the filament is soluble in acetone, so you can
"weld" parts together with just a drop or two or smooth surfaces
and create a high gloss by brushing or dipping full ABS pieces in
acetone.
ABS creates mild, tolerable fumes while being extruded. These
fumes, while usually tolerable, may be dangerous for people
(or pet birds) with chemical sensitivities or breathing difficulties.
Make sure that your printer is in a well-ventilated area and make
sure to avoid breathing the fumes.
HIPS
HIPS is a very tough plastic and can be painted and glued, it is
also recyclable. HIPS is quite a useful plastic inasmuch as it can
be used as the primary print or as a dissolvable support with ABS.
HIPS dissolves quickly in Limonene.

NB. When printing
ABS and HIPS plastic
light fumes and
smell will be emited
— the premises
where the printer is
located must be well
ventilated.
