Pick the limit you need, then use that spool's sheet. PLA versus PETG is the easier pair. ABS printing, ASA printing, and heat are the pages for a hot part and for the enclosure those materials drag in. The numbers here are PolyLite's, so the load stays attached to the degree.
Same brand, both loads
PolyLite PETG lists 220–250 °C (428–482 °F), a bed of 70–90 °C (158–194 °F), 50–100 mm/s, and drying at 65 °C (149 °F) for 6 h. The heat dataset, checked 21 October 2026, lists heat-deflection temperature 78 °C (172 °F) at 0.45 MPa and 75 °C (167 °F) at 1.8 MPa, ISO 75. PolyLite ABS lists 230–260 °C (446–500 °F), a bed of 90–110 °C (194–230 °F), 50–200 mm/s, and drying at 70 °C (158 °F) for 6 h. The same dataset lists 100 °C (212 °F) at 0.45 MPa and 98 °C (208 °F) at 1.8 MPa. PolyLite ASA lists 230–260 °C (446–500 °F), a bed of 75–95 °C (167–203 °F), 50–200 mm/s, and drying at 70 °C (158 °F) for 7 h, TDS checked 21 October 2026. HDT is 103 °C (217 °F) at 0.45 MPa and 100 °C (212 °F) at 1.8 MPa.
Enclosure required is blank on all three. The order is PETG, then ABS, then ASA because that is the question's order. It is not a ranking of strength, price, or outdoor life.
What the community says
a Reddit thread in r/BambuLab reports poor ABS layer adhesion and better luck with PA and PC when a box was required.
a Reddit thread in r/BambuLab: prefers PETG to Bambu ABS on a P1S when the part allows it.
Pros and cons
Pros
- The heat numbers are one manufacturer's ISO 75 pairs, so the load is stated both times.
- The comment that prefers PETG on a P1S is kept as a comment. It is not rewritten as a Polymaker result.
Cons
- lists ABS as cheaper, easier to sand, faster, and stronger. None of those four words is a cell on these sheets.
- Acetone vapor smoothing is named in that same comment. It is not a procedure on this page.
Printer considerations
- PolyLite PETG's bed stops at 90 °C (194 °F). PolyLite ABS starts at 90 °C (194 °F) and runs to 110 °C (230 °F). A PETG bed is not an ABS bed.
- The HDT pairs above are the same brand, the same standard, and both loads. A higher HDT is not a strength ranking and not a UV ranking.
- Enclosure required is blank on these three rows. Whether ABS needs a box is [ABS printing](/answers/abs_print), not a number this sheet comparison invents.

Questions
So is ABS better?
On these three PolyLite sheets, ABS and ASA deflect at a higher temperature than PETG, at both 0.45 MPa and 1.8 MPa. PETG prints at 220–250 °C (428–482 °F) with a bed of 70–90 °C (158–194 °F). ABS prints at 230–260 °C (446–500 °F) with a bed of 90–110 °C (194–230 °F). Heat resistance is the temperature page. PLA versus PETG is the other material pair. Better depends on which of those limits you actually hit.
Do I need an enclosure for ABS and not for PETG?
These three rows leave enclosure required blank. on r/BambuLab says PETG was easier than Bambu ABS on a P1S. How to print ABS and how to print ASA are where the box belongs.
