2023年11月18日 · Does anyone use a vacuum pump to dry your filament? I have a cheap vacuum pump which is capable of 37.5 microns vacuum. At that pressure water boils at -47C, which is why these pumps are used to clear moisture from A/C systems.

2018年7月6日 · I've got a heated dryer and it takes a long time to dry the spools. I was hoping that the vacuum method might be quicker. The one thing I would try with the vacuum is to first heat the filament. Tests I've seen on YouTube indicate the filament will dry significantly faster.

2024年6月29日 · Using a freeze dryer to dry 3D printing filament by leveraging its candy setting, which warms the material and applies a vacuum to extract moisture, is an interesting concept. Here’s a detailed analysis of why this might work and …

2020年4月25日 · The importance of dry 3D printing filament is too often overlooked! If you have problems printing a material, make sure it’s sufficiently dry! Vacuum drying works, though it’s not as efficient and effective as drying with heat. Adding dessicant to the vacuum chamber helps a …

2019年11月4日 · Netherlands-based AMTechniques has developed what they call a “vacuum filament dryer” that uses a different approach. Instead of heating the filament to a questionable temperature, they instead lower the air pressure in a sealed chamber containing the filament.

2020年9月13日 · EIBOS not only launched the filament dryer to solve the 3D printing filament’s moisture issue, but also launched another product – a filament vacuum pump, named EURUS, to prevent filaments from moisture absorption. EURUS can be used to repack the dried filament into a …

2023年4月19日 · I am curious if anyone has tried using a vacuum chamber to dry filament (mainly PLA, PETG, and ABS). In my mind, theoretically I would expect it to work in a similar way to a freeze dryer (but without the freezing). It would basically cause the water in its liquid state inside and on the surface of the filament to boil and vaporize.

2017年10月20日 · I throw a few big dessicant packs in the vacuum pump with the filament and pitch them all in the dry box. I just put a spool of PETG in the vacuum. Took about 36 hours before the spool stopped losing weight.

2021年9月10日 · Is there any value in using a vacuum pump for storing PLA filament as opposed to just putting it in a bag with silica beads? I recently saw a pump advertised for a seemingly reasonable price. (Eibos)

2019年1月22日 · I was discussing building a heated vacuum chamber vs a modified food dehydrator for my own filament drying needs with a buddy of mine. He tested both and determined, based on print quality, that the food dehydrator seemed to work better and took less effort to achieve the desired results.
