The ideal drying temperature for PLA filament is typically 40°C to 50°C (104°F to 122°F). This temperature range is gentle enough to avoid damaging the filament while effectively removing any moisture absorbed during storage or use.

It’s important not to exceed 50°C, as higher temperatures can cause PLA to soften or warp, potentially affecting its quality and printability. Always check the manufacturer’s recommendations for your specific PLA filament to ensure you’re using the optimal temperature for drying.
