Prusa, for HIPS. Typical ranges from one maker’s data sheet. Brands differ: the label on your spool wins.
Why it matters
- Its best use is as a soluble support. It is softer and lighter than ABS and shrinks much less.
- Not for supporting ABS or ASA: limonene partly dissolves those too.
Tips from the workshop
- A short soak loosens the supports; then remove them by hand.
- After limonene, let the part dry for at least 24 hours.
- Small contact area? Add a brim.
