I'm using a Prusa i3 MK3S printer. After ~8 months of printing PLA, PET-G, ABS I decided to buy some HIPS and print something with it. I cannot print >1 filaments at once, so I'm not using it as a support for ABS, I want to create some high durability working models, like gears, robot parts etc.
While the quality of my models is perfect, unfortunately their strength is disappointingly low. They easily undergo plastic deformation or break. I've tried lots of settings, some yielding better or worse results, but the problem is present regardless.
- Printer: Prusa i3 MK3S
- Nozzle: Default 0.4 mm nozzle for Prusa
- Layer Height: 0.2-0.3 mm
- Temperature: 230-240 °C nozzle, 100-110 °C bed
- Slicer: PrusaSlicer 2.0.0
I've read lots of tutorials regarding HIPS printing and they did not give me the answer to my question...
Am I doing something wrong or is it normal for High Impact PolyStyrene? At this point, the High Impact Polystyrene seems less High Impact than generic PLA.
