PC vs ABS: which technical filament?
Polycarbonate can offer very high stiffness and heat resistance — but FDM printing stays demanding. ABS remains a widespread engineering baseline on many printers.
PC (PC page FR) makes sense when service temperature or rigidity rules out easier filaments — with a heated chamber, strict drying, and tuned settings: do not underestimate difficulty. ABS (ABS EN) covers many rigid technical parts with a broader knowledge base, usually lower heat performance than PC. For heat ladders see heat tolerance tiers and the detailed heat resistance guide.
Refined workshop, enclosure, “standard” technical need: often ABS first.
Proven need for top-end heat/rigidity and suitable hardware: consider PC — not a casual upgrade.

In short
Direct answer: pick ABS for a well-trodden technical path when the temperature window fits. Pick PC when datasheets and your trials show ABS/ASA is not enough — accept drying, enclosure, and advanced tuning.
Summary table
| Criterion | ABS | PC |
|---|---|---|
| Heat (trend) | Good | Very good |
| FDM ease | Medium | Low |
| Filament drying | Recommended | Essential |
Quick verdict
ABS stays the common pivot before jumping to the hardest polymers. PC is justified when measured requirements demand it.
Outdoor / UV: also compare ASA and outdoor guide.

FAQ
Is PC always “better” than ABS?
No — “better” means fit to case. ABS can be the right compromise on ease and performance.
PC without an enclosure?
Rarely recommended — high warp risk and layer adhesion issues; follow manufacturer guidance.
