STERILISING 3D-PRINTED PARTS

GOAL
The goal of this test is to observe the effects of heating the 3D-printed parts used for housing the sensor boards. These parts were created using SLS in PA12 nylon.

SETUP

The parts (Material: PA12 (SLS)) was heated at a temperature of 120 ° C for one hour.
This test was then repeated at 150 ° C.

OBSERVATIONS

After heating up the part for one hour, the part was allowed to cool down. The part returned to its original dimensions.

diameter D18.518.518.5
length L1103.9104.9104.9
length L274.675.275.2

RESULT

After first heating a PA12 3D print at 120 ° C for an hour and allowing it to cool back, all dimensions of the piece being measured remained unchanged.

When tested at 150 °, a slight discoloration of the part was observed, but the dimensions of the piece remained unchanged.
