Per AI response: Drying at 70°C will work perfectly for both ABS and ASA filament if you leave it in longer. While the ideal rapid-drying range is 75°C to 85°C, 70°C is hot enough to efficiently drive out deeply trapped moisture without reaching the material's softening point.

Recommended 70°C Timeframe

• Lightly exposed filament: 6 to 8 hours
• Severely waterlogged / saturated spools: 10 to 12 hours (or overnight)

Why 70°C is Actually Preferred by Many

Drying at 70°C is often considered a "sweet spot" safe zone. Many standard plastic filament spools (especially cheaper cardboard or generic plastic ones) can warp or deform if subjected to a true 80°C+ environment for extended periods. Dropping the temperature slightly to 70°C gives you excellent moisture extraction while completely eliminating the risk of melting your spool or causing the filament strands to fuse together.

Don't the nylons usually want 90C plus?
