This is a valid point for anyone who prints largely with PLA. And if that's all you use then you wont need a dryer. The biggest reason to use a dryer is for hygroscopic plastics like TPU, PA, PVA, PC, and PETG to some extent. PA absorbs moisture so quickly from the environment that it is necessary to dry it before printing. Other plastics like PC, TPU, and PETG absorb moisture from the environment and a much slower rate meaning that you can usually get away without a filament dryer if you use them up within a reasonable time period. PLA is it's own animal. Now there are so many blends that each type/brand can behave differently. I've used 3 year old Sunlu filament that was stored in open air without any issues but some pure OG PLA from Hatchbox or Monoprice turns so brittle that it is literally impossible to print with because it snaps as the extruder pulls it in. In that case a filament dryer *can* sometimes recover a brittle roll. You can also use your home oven to do basically the same thing if your careful with temperatures but it's definitely more tricky getting just the right temp for an extended period of time on the ovens I've used. A filament dryer simplifies the process.

Depends on where you live/how humid it is, and what type of filament you're using.
If your area is relatively dry, and you only print PLA, maybe you don't need one.
Add in PETG, and lots of times a spool will arrive so wet even in the sealed packaging that it can't be used without 10+ hours in a dryer.
Don't even attempt printing with Nylon without a dryer.

Another cheap method to dry the filament is using the heated bed on the 3D printer with a cardboard box covering the filament.

Real question, is this needed? I have been 3D printing everyday for over a year and never really had any filament issues

That's a good reminder. It's been a while since I've used this trick. In my experience it doesn't work as well with PA6 due to the rate at which it absorbs moisture. I can dry a roll this way but throughout a decent sized print the nylon will have absorbed moisture again and print quality goes down.

How practical is this tip though? At least with my printer's firmware, if I set the bed temp and then walk away without a print job running, the printer will eventually just shut off the heaters (I never figured out the exact timing, but somewhere from 15-30 minutes), so this wouldn't work for keeping filament warmed up for the necessary number of hours. I suppose a custom gcode file could be made to just turn on the heaters and sit there for a specified amount of time, though.

In general, regardless of the dryer equipment in question, I'd argue that prevention is better than a cure, so I'd always recommend storing filament in a dry box with desiccants to try to avoid filament getting wet in the first place. My filament dryers are pretty much only used when I get a brand new spool of PETG that's wet, or in the rare instances I really want to print something in Nylon (and my dry boxes are still no match for keeping nylon dry).

For the timeout you either generate gcode for it or alter the setting on your printer.

That's not correct; PLA absolutely absorbs moisture.
Ref: https://www.3dsourced.com/rigid-i...-store-pla

Clues are rough surfaces from rolls of PLA that are already dialed in; and the if you twist and bend the end of the PLA filament it snaps rather than bends since it is brittle. Another tell tale is a crackling sound as the filament pushes through the hot end. If you open one roll of PLA and keep printing until its gone then it likely doesn't sit around long enough to absorb enough to matter. Central AC also helps a lot. Don't buy something to solve a problem you don't have.

I typically have 6-12 open rolls of PLA and PETG sometimes in odd colors. After 3-4 months the filament gets brittle and sometimes will break between the extruder and the roll: it's wet. The dryer works not just by warming it up but by getting as close as possible to the glass transition temperature; that is difficult if not impossible in a kitchen oven or just on the printer bed without either doing very little or softening the side closer to the heating element.

A dryer box or a food dehydrator can do a good job. Both need a circulating fan and a good temp control to work efficiently. This one has both but it seems it might not be hot enough for anything but PLA. (PETG wants 60-65c or higher.)

Good luck!

This dryer only runs for 48hrs, fyi. Other dryers can be set to 99hrs which works much better for set&forget

Am I missing something? I have this, and mine only does 6 or 12 hours like the description. "Setting temperature 40 °, 45 °, 50 ° C and setting time from 6 hours to 12 hours."

Yeah, for PA I use a converted dehydrator that goes to 70C on the air temperature. My PAHT-CF is wonderful for strong, rigid parts but even storing it in sealed plastic in a 20% RH dry box is insufficient to actually keep it dry enough for good printing.

I have one of these types of dryers (single spool, no fan) and it's mostly useless, mainly because it doesn't keep the spool dry. It will dry a troublesome spool of PETg, but the timer means it can't run for more than 12 hours, so it's not like I can start a multi-day print and ensure that the filament will be perfect the whole time (esp if it's rainy and cold). This Sovol box also looks like it's chained to a timer limit, otherwise I might consider three of them to feed my new XL.

If you have a food dehydrator around, I found that works best. These don't seem to have enough oomph when you need to actually dry something. I live in the desert and rarely need to dry, but if I get a really rainy day my prints fail, and I need to pop the filament into something beasty to get it dried out. Something like this wont cut it.

Now if I stored my filament in here during the rainy days I may not have to dry it to begin with though...but if you find yourself having to dry often, I would hit up some yardsales and get somethng that can make jerky.

I got one of these during the last sale. I live in a humid place so I think a dryer is needed and this is my first one I've used. I like that it can hold 2 spools but I'm not so sure how well it works. Even after its on at 50c for 4 hours it shows the humidity down only about 10 points, from 45% to around 32%. It did seem to help my PETG spool print better but I'm just not sure if it's working all that well. Or maybe I'm hoping for too much.

Yeah for sure. I really like my single spool Sunlu filament dryer. It gets up to around 70C for PA, has a fan, and can run continuously for long prints. The RH indicator levels out around 11-13% and I get fantastic PA prints with it.

It might be due to geographic differences. I live in an arid environment and PLA lasts for a long time before needing to be dried. Again, that also depends on the blend of PLA. I have some material that gets brittle after a year and some that never needs drying. I stand by my previous statement. In case it wasn't clear, I think most hobby level people do not need a dryer; if you follow good storage practices and use up material on a regular basis before purchasing more you most likely do not need a dryer for PLA, especially because there are other very accessible ways to dry a roll should it absorb moisture.
