Hi fellaz. I was wondering. Ive noticed my room is also auround 25% humidity
Do i really need a dryer in this case ??
25% isn’t too bad to begin with when compared to southern swamp lands.
You generally need to dry the new filament to remove any excess moisture and then if you keep it locked up in a dry box with desiccant it will be fine for the duration.
That is, unless you have some very hygroscopic filament (likes to suck up moisture from the air) in which case it might be prudent to have the dryer running for very long prints, but this would be for things like nylon and possibly TPU, not required for things like PLA and PETG in my experience.

Not really, but it is still good to keep it so you can dry out your filaments like TPU and PETG before use.
Thanks,

Have a happy new year!

Well, as @Lenyo mentioned, new filament is not neccessarily dry.
Once you have an issue, it really pays to rule out the basics (moist filament, build plate contimation) before troubleshooting.

I agree with the other posts here but will add that you only need to dry if you have issues with filament moisture.
If you don’t, you’re golden. If you do, you may need to look into drying.
Also, water issues are a little insidious. You can be printing along fine and then start seeing little issues, then more issues, then maybe failed prints, spaghetti, and an encased extruder. The trick is recognizing them before water starts causing real problems.
If humidity is low, filaments will absorb water slowly and maybe not enough to ever cause problems. Depending on how you store your filament you may not see issues before you finish a particular spool. But know what to look for and keep an eye out. Hopefully you never see water problems.

@NemoReborn I am considering getting the Creality Space Pi Drier, how has your experience with it been so far?
Relative Humidity needs to be considered in the context of the temperature, it has little value without that detail. That’s what makes it “relative”, temperature.
If you keep the moisture level in the air constant, and raise the temperature, the RH will go down proportional to the temperature increase.
Unless it’s very hot, 25% RH is going to be pretty low “Absolute Humidity” (there is such a thing) and drying probably isn’t absolutely necessary. But it will depend to some extent on what you are printing and what filament type you’re using.
So ultimately, the answer to the question the OP asked is “if you’re happy with the print quality, you don’t need to dry your filament, it’s already dry enough”.

As a casual who can’t afford to care too much about moisture (gotta love the UK weather) it’s good to have one if you can get one on sale but I wouldn’t go out of your way unless you print with something like PETG which absorbs alot more moisture than PLA.
Useful to have, but I’ve got fine prints in about double that humidity.

My experience with the Space Pi is that whilst it works and does dry filament, the humidity sensor will fail after around a month and will always give you a value of 15-25%. Other than the RH sensor becoming faulty, it’s a pretty decent dryer

lol, I usually can get 25% in a sealed drybox

I live in Florida and I have to dry out my petg every day before use
I’m new to 3d printing and just purchase my first one. I also live here in Florida and wanted to know what experience there is with PLA. while i do plan on using using it for single or multi color prints do i have to worry about drying the spools every single time? Also good idea to run the printer in the garage or they have to be inside in ventilated areas? any help from anyone much appreciated. thanks so much!!
