Moisture is one of the most dangerous enemies when you’re dealing with plastic filaments for 3D printing. Not keeping your filaments moisture-free can result in them breaking down prematurely, your prints getting ruined, or worse, your extruder assembly getting clogged.

 .

While there are a lot of ways to keep your filament dry, PLA is a particularly different material because of its sensitivity to high temperatures.

 .

Given the low melting temperature of PLA, what’s the best way to keep the filament dry or to dry it out before printing?

Best ways to keep your PLA filament dry before printing

 .

When drying your PLA filament, the first thing to keep in mind is that PLA has a relatively low glass transition temperature of only 70 °C. This means that a filament roll exposed to temperatures around this value has a tendency to soften and fuse, making it unusable. Instead, any method […]
