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 PETGABS/ASAPA or PC — each step raises print difficulty and machine demands.
