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.

Quote from ibak :
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.
In case it wasn't clear, "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."

Real question, is this needed? I have been 3D printing everyday for over a year and never really had any filament issues
I definitely needed to dry filament after a year or so. It became very brittle and broke while printing. after drying it worked perfectly again.

I have this. It works well but maxes at 55°, not the 70°+ needed for ABS/ASA/CF, etc so it's only really useful for PLA/PETG/TPU.

I've def noticed a difference since moving to a dryer box which I feed from. I expect to be even better in spring summer when humidity hits 60% plus daily. one i have maxes at 50C as well but it is good for keeping the humidity down ~20% range at least on the PETG I have

I'm relatively new to 3D printing. Got my first printer back in early December. After doing a lot of research on this, I realize that it would just be nice to have one on hand. This is a pretty good deal, but I found that the best bang for the buck is the Sunlu S4 which just released. I'll be getting mine later this month. It lets you dry / store up to four rolls at the same time while having built in outlets to run straight to the printer. Also has presets for all the major filament types. Im primarily PLA and PETG and did notice a lot of stringing with my PETG out of the packages. This does look like a great deal, and really if I wasn't as invested in the hobby would probably pick this up. I'm also in the camp of sometimes it's better to buy nice than buy twice. Ultimately, I think a dryer leads to a better experience but if you're just printing PLA it's not too big of a deal.

Can you elaborate on your position? Are you concerned about health risks, the instability of temperature, or the inability for most ovens to go low enough to not melt a roll?

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

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!
Only 6-12 open rolls at a time? I've probably got 75-80, but I keep them stored in airtight 20gal storage totes with desiccant inside.
It's rare for me to need to dry PLA, but it does happen on occasion.

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.
Link? I have a simple one without a fan that doesn't do much. OTOH, since I moved to stored everything in plastic boxes with desiccant, I don't need to dry nearly as often. Tnx.

Health concerns aside (as there is no clear research on it, but heating any non food safe plastic in your oven is a bad idea) home ovens typically are not accurate enough to be used properly.

Alot of home ovens overshoot the set temperature when heating, which can melt spools and filament.

Assuming you have an accurate enough oven it can work fine, but you'd need to chuck a roll in to find out.

Sunlu s2 does this, it is $70 I just got it on sale for $50ish . I recently got the comgrow filament dryer which is the same exact as this one on sale. Not good for petg which should be dried at higher temp and longer than 12 hour limit. Sunlu s2 rarely goes on sale though. It has a heating element at the top and bottom of the dryer compared to this with only heating from below. This does uneven heating. But for $40 it's better than nothing, really great if you have old filament and kept it unsealed like I did for years.

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."
You are correct, this maxes at 12 hours. I've owned two and they are more frustration than they are worth.

You found a cheap food dehydrator that fits 2 rolls of filament w/o requiring any modifications for under $38? Link please.
Quote from tCLOCK :

I live in Houston and my 3d printer doesn't have a hot bed so humidity and print area temps are critical for successful prints. Also since it's not a box, the print bed is sensitive to AC vent drafts.

I did S&S for another 10% off making it $35.xx
