Where the numbers come from
The ranges are the ones collected for the comparison table in the filament types guide, from Prusa's knowledge base articles for each material and from Polymaker and Prusament data sheets. They are typical ranges across brands. A single product sits somewhere inside them, so the label on your spool is the figure to start from.
Heat resistance is given as the glass transition temperature where the sources state one. Above it a printed part softens and creeps under load.
| Material | Nozzle | Bed | Enclosure | Moisture | Heat resistance |
|---|---|---|---|---|---|
| PLA | 190-230 °C | 40-60 °C | Not needed | Low | Tg 60-65 °C |
| PETG | 230-260 °C | 70-90 °C | Not needed | Low | Tg about 80 °C |
| ABS | About 255 °C | 80-110 °C | Needed | Low | Tg about 105 °C |
| ASA | 250-270 °C | 105-115 °C | Needed for large parts | Low | Tg about 100 °C |
| TPU | 210-245 °C | 25-75 °C | Not needed | Moderate to high | Not on the TPU95 data sheet |
| Nylon | 250-285 °C | About 110 °C | Recommended | Very high | Tg 47 °C (PA6), 66 °C (CoPA) |
| PC | 265-285 °C | 100-120 °C | Recommended | Dry before printing | Tg 147 °C (pure PC) |
| CF / GF filled | 240-285 °C | 70-110 °C | As the base polymer | As the base polymer | Depends on the base |
| Wood / metal filled | 190-270 °C | 60-100 °C | As the base polymer | As the base polymer | As the base polymer |
| HIPS | 225-255 °C | 100-110 °C | Not stated by Prusa | Low | No brand value collected |

Questions
What nozzle and bed temperature should I use for PETG?
230-260 °C at the nozzle and 70-90 °C on the bed are the typical ranges. Start from the figure on your spool, since brands differ inside that range.
Which filaments need an enclosure?
ABS needs one and ASA needs one for large parts. Nylon and polycarbonate are better printed enclosed. PLA, PETG and TPU do not need one.
