Thanks for the idea. I put ball bearings on each end of the spool rod to reduce friction as much as possible and just dumped a bunch of orange desiccant beads on the bottom of the case. That's another check on how your humidity is doing. When they turn green, it's time to replace/rejuvenate them. Humid air rises (counter intuitively) so the desiccant really should go at the top, but I couldn't think of a easy way to do it. Obviously a not-yet-existant 3D printed part is called for!

Just a small warning these heating mats do not have any thermal safetys or sensors. If you do this i think it would be better to wire in a thermal fuse for safety sake just make sure you get a good value and place it in the box preferably on or near the heater so it cuts out if it does somehow heat too much.

Great cheap idea that could easily be upsized for more spools, the only thing I would change is the hygrometer position. I used to make PID controlled egg incubators which need to be pretty precise in both temp and humidity control, those hygrometers basically use a one chip temp/humidity sensor to which air needs to have a bit of movement(notice the holes in the rear) by putting them in that closed tube filled with desiccant the hygrometer will basically give a false reading as its reading the humidity round the desiccant not what the inside the bag/box humidity is actually at. The silica also needs to have access to the air so that it can absorb moisture from it. I would maybe put the hygrometer in the same but open ended tube and put the silica in a different place, that way the hygrometer will give a better overall reading.

I store my filament in an 80L storage box (Wham style) with door draft excluder around opening. It contains a "Caravan Dehumidifier", which is basically a silica gel box which has a built-in heater for drying back out when not in use. I have had values as low as 10%rH. It does feature a bowden connector for feeding filament to printers, but that one I don't use anymore (has a piece of tube blocked with hot glue). I now use a seperate box for each printer (currently 3 + a spare for visiting printers (ones I'm repairing for folks)), started out at a 7L ASDA food box (I designed feet, spool holder, sensor holder & etc). And those contain 1 spool and a 100g sachet of silica gel. The single boxes will generally get damper slowly, and when they get to 40%rH I'll dry the silica back out.

I really like the Master Spool concept :-) Due to your recommendations (and those from CNC Kirchen and Thomas Sanladerer), my filament now lives in a sealed box (generic DIY store brand) that I just dumped a kilogram of plain silica gel beads into. The hygrometer I put in there, constantly displays "Low Level" - I think the one that I had on hand only starts measuring at 10% humidity. My admittedly very crude test consisted of printing a couple of things from a roll of PLA I had just sitting on the shelf unprotected. Loads of issues from underextrusion due to "bubbles" forming in the filament and a few failed prints due to insufficient 1st layer adhesion. The finished prints really did not look very nice. I then tossed the spool into the drying box overnight and printed the same parts the next day. Same files, same temp settings, printer sat untouched for the entire time. The prints turned out a lot nicer with the dried filament. No stringing, layers were all consistent. Personally, I do not necessarily see myself building a heater in for my filament, but then I do not normally use any highly specialized materials.
@AdrianRosca3 жыл бұрын
A fantastic idea. Improvements: Gel silicate bags mounted so close to the humidity sensor alter the result. It is possible that the humidity in the bag or at the filament is different from what the sensor indicates because the air that reaches the sensor is air near the silicate.

@AlbaderBohamadАй бұрын
The problem I see right away is that this system just heats an enclosed box with supposedly wet filament. And heating something wet in an enclosed system does not rid the system of the moisture level. It just allows the air within the system to be able to carry more moisture per volume of air. You need to circulate fresh air into the box to then be heated to carry the moisture then be blow out of the box. However, you'd then want to seal the air inlet and outlet when you're not using the box to prevent moisture from building up inside again. This is inconvenient and would require more "engineering". That's why it's enough to just build a dry box. Where you pre-heat dry the filament before you put it in said dry box. You only do this once for every filament until that filament is all used up.

@RichRap3D6 жыл бұрын
The % shown on the hygrometer is relative to temperature, so it's not the most ideal indication as we are also using a heater inside the enclosure. You will actually see the percentage rise up after switching on the heater, this is quite normal and to be expected. What you are looking for is stability of the system - so for me that's around a display of 30 degrees C and a percentage of also around 30% If you use the same sensor in a sealed bag with silica gel, and the temperature drops, and the silica gel takes moisture out of the internal atmosphere, you will see readings of room temperature and percentages of around 10% to 25% if you just leave the same sensor out on the shelf, you will see much higher readings depending on where you live and the ambient conditions. Short answer is that the heated drybox is to keep things warm, dry and stable. so a reading of 30 degrees and 30% is really good, and it's all working well. An even lower percentage is even better, but it's more important to keep things consistent, this way every time you use the material you should get the same quality print results. I hope that helps, and sorry for the delay, I have been away.

Congratulations on the success of #Masterspool. Now, I understand the reason for wanting a low humidity environment for your filament but what is the reason for it being heated? The concerns I have with the design of the box is that the heating element is only heating one side of the spool at any given time so wouldn't that create some warping as it expands and contracts possibly bring the filament out of tolerance? Then too the filament is feeding off the top so aren't you losing any advantage to preheating your spools as its cooling while moving away from heat source? And since it's feeding through those long tubes wouldn't the filament essentially be room temperature by the time it reaches the print head? If you wanted an all over ambient temperature I would think moving the heating element to a more open spot and using a small fan to distribute the air would be more effective like a convection oven. This would also help the silica do its job and you would avoid any humidity condensing on cooler surfaces like the lid. But if you just wanted warm filament to feed into your printer winding it from the bottom might be better as its at its warmest in that position.
@RichRap3D6 жыл бұрын
Hi Fern. The heater gently heats the air inside the box, that translates to the entire spool and everything else inside the box including the silica gel etc. It's only a small, gentle heater, just keeping the inside around 32 degrees C - this really just helps drive out the moisture from everything inside. when in use the coil is turning, but it's all around the same temperature, and I have not seen any negative issues for the materials. Only improved print quality and less brittle materials. Hope that helps.

I take a smaller dollar store tupperware container and pass the filament through a PTFE tube and outlet. Use the filament holder flat, rotating on a printed holder. Dessicant is not necessary, because I have yet to see the dessicant turn color with small volume containers. The heater is not necesary either. Take a dry spool, in a small container, compare with and without dessicant, with and without heater. Neither desicant nor heater is necessary.

Instead of silicon packs, design with space for "Eva-Dry Wireless Mini Dehumidifier, White (E-333)" - re-usable forever. Maybe a bracket to suspend from lid, positioned towards back of box.

I looked at this. The description includes "Super dry dehumidifier unit lasts 20-30 days before recharging the silica gel beads." so you need to replace the silica gel anyway.

Great video! a question, if I may. I was thinking of adding small 12v fans to extract air - so it would warm and then the fan would extract the "humid" air from the box. Would you advise against that?

If you put a simple extraction fan on a box like this you are removing hot air from the box, invalidating the heating element's work, wasting energy by lowering the temperature inside the box. Use silica/desiccant bags to absorb moisture, like in the video. The heat is needed to "coax" the humidity out of the filament, into the air, so the silica can capture it. You can add a fan INSIDE the closed box to improve air circulation around the spools though.

Seems a short term idea...save the makers supplying “free” spools...( part of production costs). Then, they sell you empty spools. I have a great idea....stay just as it is! Next somebody will come up with the idea that when shipped, just use plastic supermarket bags!
