Finding the right temperature for your PLA filament can be frustrating. Print too cold and you get poor layer adhesion and weak prints. Print too hot and you deal with stringing, oozing, and loss of detail.
We spent months testing over 20 different PLA filaments across multiple temperature ranges to take the guesswork out of dialing in your prints. Here’s what we discovered.
Why Temperature Matters
Temperature affects everything about your print quality. The right temperature gives you strong layer adhesion, clean details, and consistent extrusion. The wrong temperature leads to problems like stringing, warping, poor bridging, and weak parts.
Different filament brands use different additives and formulations, which means they all have slightly different optimal temperature ranges. What works for one brand might be too hot or too cold for another.
Our Testing Methodology
We tested each filament at multiple temperatures, typically starting at 190°C and going up to 225°C in 5°C increments. For each temperature, we evaluated layer adhesion, surface quality, stringing, and overall print quality.
Temperature Results by Brand
Elegoo PLA
Tested Range: 190-225°C
Best Results: 220°C
Elegoo PLA performed consistently well across a wide temperature range. At 220°C, we got excellent layer adhesion with minimal stringing. The filament flowed smoothly and produced clean, detailed prints.
GIANTARM PLA
Tested Range: 190-220°C
Best Results: 200°C
GIANTARM’s Matte Navy Blue PLA preferred lower temperatures compared to other brands. At 200°C, it produced beautiful matte finishes with good layer bonding. Going higher resulted in a shinier surface that defeated the purpose of the matte formulation.
Inland PLA+
Tested Range: 205-225°C
Best Results: 215-220°C
Inland’s PLA+ variant needs higher temperatures than standard PLA due to its tougher formulation. We found the sweet spot at 215-220°C, where it balanced strength with print quality. Their Purple PLA+ was particularly impressive at 220°C.
Inland Silk PLA
Tested Range: 190-220°C
Best Results: 220°C
The silk formulations need heat to achieve that characteristic shiny finish. At 220°C, the Rainbow silk PLA produced stunning color shifts with a glossy surface. Lower temperatures resulted in a duller, less impressive finish.
Polyterra PLA
Tested Range: 190-220°C
Best Results: 220°C
Polyterra’s eco-friendly PLA printed beautifully at 220°C. The Fossil Grey and Peanut (Matte Brown) colors both produced excellent results with good layer adhesion and detail.
Sunlu Meta PLA
Tested Range: 205-225°C
Best Results: 205°C
Sunlu’s standard white PLA preferred slightly lower temperatures. At 205°C, it gave us clean prints with minimal stringing. Their Meta series (metallic finish) varied by color but generally worked well in the 205-215°C range.
Key Takeaways
After all our testing, here are the most important lessons:
Start with manufacturer recommendations, then fine-tune. Most brands provide a temperature range on the spool. Start in the middle of that range and adjust based on your results.
Standard PLA: 200-220°C is usually ideal. Most standard PLA filaments work best somewhere in this range. Brands like GIANTARM prefer the lower end (200°C), while others like Elegoo and Polyterra shine at 220°C.
PLA+ needs more heat. Modified PLA formulations like Inland’s PLA+ typically need 5-10°C higher than standard PLA to achieve their improved strength and layer adhesion.
Specialty finishes have specific needs. Silk and metallic PLAs need higher temperatures (220°C+) to achieve their characteristic finish. Matte PLAs often prefer lower temps to maintain their surface texture.
Watch for stringing. If you see excessive stringing at a given temperature, drop it by 5-10°C. If you’re getting weak layer adhesion or the filament seems to be struggling to extrude, increase the temperature.
How to Dial In Your Filament
When you get a new filament, here’s our recommended process:
- Check the spool label for the manufacturer’s recommended temperature range
- Print a temperature tower starting at the low end of their range and going to the high end
- Examine each section for layer adhesion, surface quality, and stringing
- Pick the temperature that gives you the best balance of strength and quality
- Test with a real print to confirm your settings work for actual parts
Temperature vs. Other Settings
Remember that temperature doesn’t work in isolation. Your print speed, cooling fan settings, and retraction settings all interact with temperature. If you’re having issues:
- Stringing? Try lowering temperature or increasing retraction
- Poor layer adhesion? Increase temperature or reduce cooling
- Warping? Check bed temperature and reduce cooling on first layers
- Oozing? Lower temperature or increase retraction distance
The Bottom Line
There’s no single “correct” temperature for PLA. Every brand, color, and even different batches can vary slightly. The best approach is to test your specific filament and find what works for your printer setup.
Our testing showed that most standard PLAs work well between 200-220°C, with 215°C being a good starting point for most brands. From there, fine-tune based on your results.
