- In this video we're putting together a Jumbo Sized Heated 3D Printer Filament Dry Box / Hot Box. If you have many spools a filament and are struggling to keep them dry and climate controlled this video will show you how to use a storage tub and a few other parts to keep things fresh! The dry box contains a heater to keep the filament warm along with desiccant and a PID controller for the heater. Store 30 rolls or more of filament in just one box!

Do you have a filament dry box? Will you be building one?
I plan on building one
I just made one using a PI rather than PTC heating element and a EPP Box for Food Delivery :)
Fits 2 3Kg Rolls, goes up to 100°C (so you can dry nylon) and cost less than 100 € to build. Was fun too because for once nothing went wrong xD
Do you have any calculations/calculator for the size of PTC Heater needed for the dimensions of the box to be used?
@darrensimms8761 no but should be easy to calculate based on cfm and BTU
@@darrensimms8761 Try to estimate your loses to the environment than add another 50 Watts per Spool. You can always reduce the power of a heating element, increasing it however is difficult. I would also try and not use a PTC if possible since they are a pain to control and different Filaments will require different temperatures to dry.
Nice video. If humidity was an issue where I live, I would definitely build one like yours.
I've got a solar oven I use. I prop the door open a little so it doesn't get too hot (warped a spool before I learned that). Half an hour or more and my TPU comes out perfect, not to mention PETG
3d printing off-grid
THANKS.. ALL YOUR VIDEOS CLEAR..SAMPLE AND EASY TO UNDERSTAND (GREATEST MAN)
Thanks for the kind words. Glad you're getting value from them.
Thanks for the design, I like your designs and know it takes a lot of background research to get even a simple thing like this working. I didn’t know about those heaters!
I won’t build one, cost advantage isn’t there, admittedly filament driers can only do one or 2 spools at a time but the clincher is the fire safety aspect.
Maybe just an incandescent light bulb would be better, gets away from the power supply and a usb charger can run the fan. Those terrarium heaters would also work, they screw into a bulb socket.
Your design is for storage, a bit different to a filament drier which has a port for the filament so you can use it whilst printing. Your design doesn’t use much more space than you would need to store the filament already. I suggest a drawer would also work if you store your filament there at the moment, maybe repurpose a small filing cabinet - still using all the design aspects you used.
Love the Knight Rider theme music! :)
Love your videos, man! Make a two roll or one roll edition!!! Cheers from Vancouver :-)
I just dried some of my first spools last night in a food dehydrator. I could only get in one spool at a time so I see the advantage to doing a whole bunch like you can do.
I was wondering if the heater/fan and PID controller could be used as part of a heated printer enclosure? I have my printers in an enclosure and the heat up passively from the printer but it would be nice to add a heater and controller to get to a higher temperature and also control the temperature. What do you think?
Absolutely could. It's a good idea.
Thanks. I followed your link and found a 250 watt, 24V model that I can use with the old power supply I replaced on my Ender 3. Thanks for the inspiration.
It would’ve been nice if you’d started with what is a hotbox? And why would I want to use it?
In the process of making one of these now, just wondering what size power supply you used
It was a 20a 240W supply amzn.to/36rPMAN
I am building a small one of these when I have more than my daVinci
Just a note. I have been cutting long lines for many years, a little advice. You used the ruler to draw a line, then you free hand cut with an exacto. Try skipping the pencil step, simply use your knife like a pencil and the ruler as the straight edge and I guarantee a perfect straight cut every time. oh yea.. you should lose the exacto and replace it with a proper utility knife.. I see an accident waiting to happen. Exacto's are for cutting paper on a table. Don't get me wrong,, I really like your video's and your projects. I just see you have not done a lot of construction work.
With that being a sealed enclosure and the moisture having nowhere to go didn't you just basically create a humidor for your filament? Desicant releases moisture when heated. I believe it does this at a higher temperature than what would be within the enclosure but it is setting right next to the heater where it will be the most warm. I think its a cool idea just not sure how efficient it is. Have you put damp filament in and successfully dried it with this or is this strictly preventative? Would love to hear back from you!
The container while closed is not sealed. It is not air tight. Desiccant does release moisture at higher temperatures but the dry box is well below that temperature. So the desiccant does absorb moisture and keeps the filament sub 20% humidity most of the time. The box was preventative not designed to dry filament out. I imagine it would slowly over time dehydrate filament due to the overall conditions inside the box but that was not its primary purpose. I've validated the dryness in there through multiple meters. I also have
filaments like Carbon Fiber PLA which came with paper based humidity indicators which also have those below 20%. The box has worked quite well since it was built and I have had no problems with moisture. The box is in the basement which normally would trash even PLA after a few months. The rolls I pull out of here are as fresh as the day I bought them. I have had no problems with this setup.
Makers Mashup Thanks for the reply! Great info!!!
u should put psu outside not inside, anyway gj bro
Has anyone tried to see if filament can be dried "On the fly", by passing it through something like a heated tube thats hot enough to dry/boil the water out but not hot enough to melt the filament, before cooling then into the normal extruder etc? A sort of warm-end pre-heater.
Great idea but I think you would have to have it in there a long time to have an effect. Haven't tested it but thinking how fast filament moves through it would have to be very slow. Interesting expeiment for sure.
Yeah filadry for example does this. Its too slow to dry filament fully. The speed at which you print and your feed rate would have to slow down to let the unit do its work.
What not use a large foam ICE chest :)
Can't use that its keeping the beers cold. 😉
Hotbox? Where's the 301 video?
You mean these? CoreXY DIY 3D Printer - LayerFused X301: th-cam.com/play/PLyYZUiBHD1QgZ4tn9tMU3Z-l71JyhPW9l.html
@@MakersMashup Yep, thanks. One of the previous BOM spreadsheets linked to this instead of x301
Vacuum is a far simpler and cheaper way to store filaments. I have special bags for storing spools individually. A heated box makes sense only to dry, not to store filaments. So I see no reason to make larger then needed for 1 spool.
Vacuum is a great way to store them long term. Totally agree. Personally though I'm changing filaments often and personally like the convenience being able to open a box and exchange rolls. I use a a smaller one for food all the time and it produces a ton of waste on bags. Granted with some longer bag work you could reduce your waste but for the number of rolls I had this made far more sense for me. I do however totally agree with you that vacuum is a simple and easy way keep filament fresh.
@@MakersMashup I use ziplock vacuum bags with a hand pump, those are reusable. I was sceptical at first about them being able to stay vacuum, but they do really well. Bags are like 1.5usd I think and the pump was 5usd or so
If you have a link to them can you post it, I would love to check it out.

Oh you're using those. Wow. I've seen those before but didn't think they would hold up. I will certainly check those out. I presume you're using a gallon size?
