What is HIPS used for in 3D printing?
HIPS (high-impact polystyrene) is best known as a dissolvable support material for ABS — limonene dissolves HIPS — not as a first choice for a heavily loaded final part.
In FDM, HIPS typically supports ABS prints: after printing, the model can be bathed in d-limonene (or similar formulations) to remove HIPS supports — with proper safety and process. It also appears in mock-ups or paintable prototypes. For mechanical final parts, prefer ABS, PETG, PA, etc. Full detail: HIPS page (FR). Compare soluble supports: PVA (FR), BVOH (FR). ABS (EN).
Main goal: soluble supports for complex ABS geometry.
Final loaded / hot part: usually another filament.

In one sentence
Direct answer: HIPS is mainly a printed support dissolved with limonene to free complex ABS models; it is not the polymer you pick first for a final mechanical part under load.
Support vs final part
| Criterion | HIPS as ABS support | Final technical part |
|---|---|---|
| Main use | Overhangs, dissolution | ABS, PETG, PA, PC… |
| Typical solvent | Limonene | — |
Quick verdict
Treat HIPS as a process material (support), not a universal engineering substitute. For impact or load, see impact guide.

FAQ
HIPS with PLA?
The classic soluble pair is HIPS + ABS; PLA workflows often use PVA/BVOH-style supports instead.
Limonene safety?
Follow SDS and local rules: ventilation, containers, no ignition sources — this guide is not a safety datasheet.
