Guide
Which material tolerates heat in 3D printing?
“Handling heat” depends on real temperature, duration, and load — not a marketing label alone.
This page gives a tiered decision ladder: from PETG (better than PLA, not “high-temp”) to ABS, ASA, PA6/PA12, and PC. For scenario detail (car interior, sun, motors), use the full heat-resistant guide — it complements this ladder. Sheets: PETG, ABS, ASA, PA, PC (FR). PA6 vs PA12, PC vs ABS.
Mild indoor heat: often PETG as first step.
Sustained heat / technical: ABS, ASA, then PA or PC depending on need and hardware.

In one sentence
Direct answer: drop PLA when heat is real; step up PETG → ABS/ASA → PA or PC — each step raises print difficulty and machine demands.
Tier summary table
| Material | PLA | PETG | ABS | ASA | PA | PC |
|---|---|---|---|---|---|---|
| Heat (trend) | Low | Medium | Good | Good | Very good | Very good |
| Ease | Very high | High | Medium | Medium | Low | Very low |

Does this replace the detailed heat guide?
No — this page is the ladder; the other guide covers situations in depth.
