11 Materials
Temperatures and the heatbed treatment before print according to a specific material.
11.1 ABS
ABS is very strong and versatile material with
​
great thermal resistance
​
. It’s suitable for
both indoor and outdoor use.
ABS is a thermoplastic polymer, that means that just like PLA, it can be melted and
crystallized multiple times without degrading too much. ABS, however, melts at a higher
temperature than PLA. Higher melting temperature gives ABS great thermal resistance, your
prints won’t show signs of deformation
​
up to 98 °C
​
.
ABS includes high wear resistance synthetic rubber, which makes it
​
very strong and
impact resistant ​ . And last but not least, it’s ​ soluble in acetone ​ ! This makes it really easy to
not only connect multiple parts together but also allows you to ​ smooth prints ​ with acetone
vapors. You still have to be careful when handling acetone, but it’s not anywhere near as
dangerous as for example PLA solvents.
The best use of ABS is architectural models, concept models, spare parts (car
interior, gears, phone cases), etc.
On the other hand, thermal contraction is where ABS makes it really hard to successfully
print something. And that’s especially true when printing anything big. Even with the heatbed
at 100 °C, your part may start lifting from the build plate and warp. This and the
​ unpleasant
smell
​
of ABS is why you should consider getting an enclosure for your printer when printing
with ABS. Or at least place the printer in a warm room.
If you need to use your print outside or just need your print stronger, give ABS a shot. It’s
what
​ LEGO ​ is made of after all.
ADVANTAGES DISADVANTAGES
High impact and heat resistance Bad smell
Strong and versatile Worse resolution
Soluble in acetone (easy post-processing) Needs warm room or enclosure
Can be vapor smoothed
● Nozzle temperature: ​ 255 ​ ​ °C
● Bed temperature: ​ 100 °C. You can set the bed temperature between 80 to 110 °C
depending the size of an object (larger object means higher temperature)
● Heatbed: ​ Make sure the surface is clean as described in ​ 6.3.2 PEI print surface
