How to find the best temperature for your filament
The right temperature depends on your printer, hotend, speed and even the colour of the filament. A temperature tower finds it in one print.
- Download or generate a temperature tower model. Many slicers include one in their calibration menu.
- Set it to step through the material’s range, for example 220 °C down to 190 °C for PLA in 5 °C steps.
- Print it and compare the sections for stringing, bridging, overhangs and surface finish.
- Pick the coolest section that still bonds well, then try to snap it. Weak layer bonding means the temperature is too low.
Signs your temperature is wrong
| Symptom | Likely cause | What to try |
|---|---|---|
| Stringing and blobs | Too hot | Lower by 5 °C, check retraction |
| Layers split or snap easily | Too cold | Raise by 5–10 °C |
| Clicking extruder, gaps | Too cold or too fast | Raise temperature or slow down |
| Corners lift off the bed | Bed too cold or draughts | Raise bed temperature, use an enclosure |
| Elephant foot on first layers | Bed too hot | Lower bed by 5 °C |
Keep filament dry
Most filaments absorb moisture from the air. Wet filament pops and hisses at the nozzle, strings more and prints weaker parts. Nylon, TPU and PVA absorb moisture fastest; PETG and PLA more slowly. Store spools in sealed boxes with desiccant and dry them in a filament dryer when needed.
Frequently asked questions
What temperature should I print PLA at?
Start at about 205 °C on the nozzle and 60 °C on the bed, then adjust within 190–220 °C. Faster printing needs higher temperatures.
What temperature should I print PETG at?
Start at about 235 °C with a bed of 75–80 °C. Use a little less part cooling than for PLA to keep layers bonded.
Do I need an enclosure for ABS?
In most cases, yes. ABS shrinks as it cools, and draughts cause warping and layer splits. An enclosure keeps the air warm and steady. Ventilate the room, as ABS gives off fumes while printing.
Why is the temperature on my spool different from this chart?
Each brand tunes its plastic differently. The manufacturer’s range is the best starting point for that spool; this chart is a general guide.
