How do you treat brittle PLA?
Probably the easiest and most common way of drying filament is throwing it in the oven. Just set the temperature to right below the glass transition temperature of the plastic, and leave it in there for four to six hours for the moisture to evaporate. The longer you leave it, the drier it’ll get.
Does PLA break down over time?
PLA. Due to being made from a bio-degradable material it means over a long period of time, PLA is going to slowly degrade. This process however, can take a very long time, to a point where it won’t have much impact on it’s functionality. There are factors that make PLA decay faster such as heat, UV rays, humidity etc.
Why are PLA filaments so brittle in 3D printing?
It’s frustrating how your attempt to print a 3D prototype results in having the PLA filaments breaking off at the slightest touch. We know that PLA widely use in 3D printing, but their tendency to go brittle has frustrated many hobbyists and professionals alike.
What should I do if my PLA filament is brittle?
When dealing with brittle PLA filaments, prevention is always better than cure. If you’re having regular issues with PLA filaments snapping into pieces, you’ll want to stop leaving the filament on the 3D printer after usage. Instead, ensure that the filament retracts into the reel after printing and store in a sealed pouch or container.
Can a 3D printer get clogged with PLA?
The print head gets clogged easily, and when the object does print, it’s quite brittle and 1/4″ to 1/8″ rods will easily snap off if not handled gently. I’ll admit to not following the precautions for storage of PLA.
What to do if your 3D printer is getting brittle?
If you’re having issues with brittle 3D prints, you could increase the temperature of the nozzle. This ensures that sufficient heat is applied to both evaporate the moisture and soften the physical form of the PLA filament. You’ll want to try a few different temperatures to get the ideal value that works.
