Awsome video Master, thanks for the tip and more importantly for investing the time to create a build tutorial that have been missing from the start :) I have added your video to the thinguiverse.

Instead of drilling holes for wire in the lid, you can print adapter between base and lid, wich has a hole or slot for the wire

Great project. It's on my to do list. I have my printers on very cold place... sometimes goes down to 6 degrees, so this is a great solution. Thank you VOG and has always a great video.

Thank you for taking the time to put together this great instructional video. I just finished building one and it worked perfect right from the start.

Great video! I live in Canada and have my printers in the basement. Having the resin at these higher temperatures makes a BIG difference. I have a similar rig but it is inside a Creality tent. The housing and magnets is a great idea.

Been using it for a year now, and makes a HUGE difference! Totally recommend!

It's a great design and used one for over 2 years myself. Thank you for the mention and explaining so well how to build one ☺️

I'm actually using this heater for my Saturn semi automation project. One thing I would advise to anyone is grab a thermal fuse and place next to the ptc heater. If the fan fails, that heater, heats very quick and can potentially cause a fire.

Thank you so much for making this video! I have my printer in a pantry (with an exhaust fan to the outside), and it gets quite cold in the winter. This is exactly the solution that I needed! Also, your channel is top 2 among my favorite 3D printing channels, keep your awesome videos coming!

I just wanted to thank you. I recently finished building a modified version of this PTC heater with an extended housing and a power switch built in. I shared it on Thingiverse in the remixed versions of the original the link you shared. Your video and the supply links provided in your description were infinitely helpful. It is well paced, concise, detailed, and made the project much easier and straight forward. I tend to run my house colder than most in the winter, and this heater has made it so I can reliably print again. So again.. thank you for posting this video. Also I hope you don't mind.. I captured a screen grab of one of your wiring diagrams, modified it to represent my build, and included it in the pictures for the build on Thingiverse. I made sure to mention your video in the description. This is a truly excellent video.

I just want to thank you for the patient, well enunciated, and highly efficient and informative summary of the programming functions of the thermostat. The instructions are printed so small as to be nearly illegible, and what can actually be read is almost incomprehensible.

This is just the type of tool and instructions I might resort to. Thanks so much for sharing this!

Vogman, a hero among the thorns. Thank you for your content.

If only this came out last week. I started building a small chamber heater for my VoxeLab Proxima using a 120w heater instead of the 100w you used. I was trying to design my own case for it to hold a W1209 temp controller, but then saw this video. Ordered the smaller controller you used and printed the case last night. Came out perfectly (it is temporarily in my spare bedroom all toasty) once the controller comes will wire up. I presumer the side circles on the case are also for magnet placement, so I can stick it on the side of the metal column.

Amazing! With this walk-through, even my mum would be able to make this! Awesome video as usual :))

Thank you so much for such an informative and easy-to-follow video - just finished the second of these heaters to keep my two resin printers printing reliably through the UK winter :)

I was literally thinking about how to build a heated enclosure two days ago. Thanks!

Thank you for this, I ordered everything and have downloaded the heater body stl files, but what i have done is elongated the body an extra 20mm to give me a bit of extra space to work with, I highly recommend people do this, thanks again.

These little heaters are worth their weight in gold. I made a similar one when I got my printer a year ago. My printer is out in the garage - I printed throughout the winter with no problems. I'm certain this wouldn't have been possible without it. As usual, your explanations are very well articulated! Please never stop making videos!

Even watching the vid itself is fun. Thank you for sharing!

I love when you can print something for the printer. or anything useful! so cool!

Thanks for sharing 👍 You made an excellent guide with easy to understand instructions.

Well, it wont be my next project (workshop is pretty warm even in winter), but this looks like a great little item. Well done to the guys that put this together! It looks bloody useful.

Looking forward to seeing your heater in action all the best Geoff 👍

I intend to print in the garage, living in scotland this is an awesome video, thank you

Another VOG upload in my subscription feed = another great morning =D I built something similar last year, but mine wasn't as elegant. I had a spare generic heat controller from an old soldering iron and a solid-state relay. Mounted it all in a (much larger) box with a wall outlet as the output so I could plug in a small space heater. I used a bit of painters' tape to mount the thermocouple just next to the resin tray. When it drops below the setpoint, the outlet becomes live and powers the heater. I just pointed the heater at the printer. Crude, but it got me through last winter with minimal issues! =D

very worth while having these, i added a ptc heater to the case permently rather than this solution. But they work so well. it annoys me that printers dont come with this built in.

Love your video! I will be adding this to my Christmas shopping list. However, rather than need a thermometer or device to check the temps...place the RTD into a glass of ice water. I do this quite often as an Industrial Automation Engineer. You can use a kitchen temperature device just to double check your glass of ice water. Seems like extra steps...but if you have OCD like me...make's life simple! Once again...love your videos! This one has garnered a subscribe mate!

Thanks a lot for this walk through - built it this afternoon (it works!) and will try it out in my Elegoo Jupiter tomorrow. I modified one thing: I connected the negative lead of the fan to the same position as the negative lead of the PTC heater. This way the fan only runs when the heating is on. Might mod change that if I find that this doesn't work as well.

Thanks for this great tip, and how-to-guide. I've just ordered all the items, and can't wait for them to show up, so I can get back to 3d printing - The room I currently have my printers in has become to cold to print in, so I really hope this will make it possible to print over the winter :)

A fantastic walk through for a great design. Great job all around!

Thanks for sharing, will definitely be looking into this once I get my Phrozen Mini 8K in January. Great video and instructions!

Very nice video, definitely useful as i'm planning to set up an enclosure with fume extraction and needed to figure out heating, putting the heater element inside the printer definitely seems like a much better idea than heating up the entire enclosure.

Great video. I am going to give it a try. However I decided to print the cabinet på an filament printer. It gives me a more sturdy cabinet.

I printed one of these for my OG Photon a couple of years back. My setup is super jank but it works well. I actually merged the thing with a new side piece for the Photon. So I removed one of the the orange windows and put a plastic side in that I printed with the heater fitted to it.

Excellent video. Thank You. Alternatively, you could move to Texas where I'm at and enjoy a 24/7 46 Celsius HEAT box I call a garage. It does drop enough in the winter for my FDM printer to have issues though, but the winters here are relatively short and mild compared to most places. By the way, your instructions are so clear and concise even a complete novice should understand them easily. Screw Terminal A/C two wire adaptor!?!? Where has this thing been all my life!?! Buying a big pack of those!

Thanx for the how-to! I will consider doing something similar when I start 3D printing! :D Take care Geoff!

Thank you for the detailed tutorial! I have my printers (FDM and resin, including curing station) in ventilated enclosures so I simply put an incandescent 60W light into the resin enclosure (not inside the printer cover, of course). It improved my print results for sure. I also sometimes use a small crock pot (it came with the big one to be used for melting chocolate I believe) to pre-warm the resin itself. I can somewhat control the temperature by changing the fan speed of the enclosure. I love tinkering so maybe in the future I'll try this setup. Reminds me of the time when I hooked up my wine cooler to the fermenter I had inside to control fermentation temperature :)

I've been increasingly active on the resinprinting reddit page and heaters have come up quite a lot lately. Purely as a mostly plug and play alternative, I've recommended using a reptile heat pad for a passive heat source that can be mounted directly inside the printing chamber. I happen to have one from an old fermentation acceleration experiment I ran several years ago, but they can easily maintain a small, enclosed space up to 30*F over ambient depending on the size you use. My print room is also my utility room where my washer/dryer is, so when it gets cool enough to affect my print temps, I'll suddenly be urged to do laundry and run my dryer to my indoor entrapment box, but for those in other areas that may not want to fiddle with the electronics (and barring the day I don't have dirty laundry, haha) I'll be going this route myself. I do like the work put into this solution though; good forward thinking, and having active temp control is really nice!

thanks! just what I was looking for!

Great idea. Have a phenom and can only use on hot days or somewhere heated.

Thanks for this VOG, i've been doing mostly 3 hr prints i achieve this by immersing the resin bottle in a pan full of hot tap water for aboot 10 minutes then shake the bottle for aboot 2 mins then pour, but like you say winter is coming and with windows open for ventilation the resin will soon cool so again thanks!

it works very well. Great Job! Thanks

This is a good idea. I was just going to buy a electric heated blanket put it over my saturn for the winter prints

great stuff, this is what I needed

I've been using one of these since last year and it's a fantastic and simple solution that's very easy to put together. One thing to note is the check your printer to see if there's a good magnetic mounting place, the z-arm for the Saturn is non magnetic, so I ended up printing a arm to hold it as well.

Another fantastic how to video! I just wish I had the time to make one.

Awesome video just about to print now I have all the parts only thing is have I missed the cable sizes that are required.

Thanks for this walkthrough. I will make one :-) very helpful and to the point ;)

Awesome video definitely keen to see how your future prints go. Especially keen to see how it goes with siraytech castable resin

Id love to see a couple of test prints with and without the heater in winter. Would be interesting to see how dramatic the difference is.

This is great! I've been wondering how I'm going to keep printing through the winter in my garage.

I was able to add a heater to my elegoo saturn using a fermentation belt for brewing beer. I glued the belt to the vat so I'm only heating the vat not the air in the enclosure. Haven't had cold enough weather to need it yet but will be trying this winter.

Nice build had an extra one from Making active heating for my fdm printer. Surprised new resin printers don’t have these built in. Heck might open the possibility for more industrial resins since they can require higher temps.

Great video! Should have the parts coming tomorrow for my build and then my Saturn should have a nice cosy enclosure. Going to make a riser out of some 3mm foam board so I don't have to cut into my cover for cable clearance.

great idea, i think i would just use another 4 slightly larger magnets on the outside to hold the heater, then it would be completely reversible if needed

Great video as always :) thanks for the tip.

Great idea, built it and it works great. 🤩👍🖖

That putty was a good stress relief... But I’d love to see you try some flexible resin 3d prints for video builds like this. 🎅🏻🇦🇺🤜🏼🤛🏼😂🍀🍀🍀😎

This is pretty awesome! Might make me one once my Elegoo Jupiter shows up!

I'm going to try this, I'll also get a timer switch so it will switch off in time with the printer

This would have been great for me to know last year but I have made a full enclosure to cover both my printers with the ridged foam insulation and I use a space heater with a thermometer build in so I just turn it on it will keep both warm and I have enough room to keep the resin bottle so if I have to add everything is at the same temperature

just got a flashforge foto 9.25 and its in my conservatory it get bloody cold in there, just managed to print the case perfectly and bought all the parts from amazon along with a 120*C fuse just in case. i fixed it in place with magnets outside the enclosure. works amazingly. thanks for the guide

I've tried an enclosure hoping the ambient temp got above the minimum. It didn't so looks like this is what I need.

Really nice idea. I've currently got a 40W Dimplex ECOT1FT tube heater mounted on the inside of a cardboard box, with the Mars 3 inside that box; with the intention being to build a proper enclosure with insulated walls in the future. It does mean it needs to be a fair bit bigger than the printer so the lid can be lifted off (at an angle) - or just left off while printing. As you note; the Mars 3 lid may be too small/curved to mount this smaller heater on the inside, but I suppose it should be possible make a new lid with enough space (and may even space for the little Elegoo filters).

Did you notice that the sonic 4K 2022 model has a similar heater now built in. Although it’s controlled via the GUI and LCD Great video as always.

I'm awaiting delivery of the parts but have already printed the enclosure (FFF version). For those without metal surfaces to attach, consider that one can place matching magnets on the outside of the cover to place the device anywhere desired.

Great video, thank you! My relay is causing the unit to turn off. Perhaps its a bad power supply providing too little current? Its the 10a 12v model but seems super lightweight and low quality?

Ehm my mars 2 is in my shed where its bloody cold, and it doesn't fail and prints super crisp. I use water washable resin.

THX for the presentation however after seeing this I wonder why something like this is not part of the printers in the first place regarding that prints are so dependend on optimal temperatur when it comes to resins.

This is a fantastic find and a great tutorial on it. Now all I have to do is make sure that at least one of my machines is wrapped up warm enough for Norn Iron autumn/winter to print the body then repeat three times. Awesome video as always, keep up the good work.

Love the video, but still confused about the wiring for the electronics. Do I need to also get a set of 12 gauge, black and red wires to connect everything to to the power supply? Just not sure how everything gets connected to the power supply.

I run a dehumidifier in my print room... serves to keep room warm (85-90ºF) and humidity down around 15%

I normally print in my garage but can't in the winter so I bring it into my kitchen, which could be risky for other people in the house. I should use some sort of heater like this.

Thanks for post will give it a try

Oh that is super useful. I don't understand why no printer manufacturers have even touched this built in or as an addon. I'd pay £99 right now for one that's designed to fit perfectly with my MonoX and I bet a whole lot of others would too. I wonder why no printers at all for resin have heaters and yet so many for FDM have heated beds? We know its necessary to print at above room temperature so heating is kinda needed. Anyway, call out to manufacturers to make something you can just slot in and go without the DIY! RN I'm using our outdoor patio heater thing in the shed and get up to 28c ish before I'll even consider starting a print. Its made a huge difference to print reliability but I don't like to think about what that added cost of heating the entire shed is. It is nice being all warm and cosy in the shed though, so there is that plus to a bigger heating solution haha

Hello, nice video. I want to build such a heater by my own and have all parts and the casing. But do you have a good idea how to switch from the power supply unit to some kind of rechargable battery pack? I would prefer to build that heater so that it doesn't need an extra cable outside the chamber ...

will be doing this for mine :). BUT, notice the weird light anomaly, or ghost orb at around 11:25 to the left of your printer cord :) right where you say 'straight UV light'. It appears, goes in an arc angle, and vanishes.

Great Video, got most of the stuff on order, however, I wondered what size fork connectors you use? I've seen 5 different sizes and didn't want to get the wrong size.

Excellent as ever. I will be making a heater now the winter is coming out of the electrical stuff I have on hand. I wonder if the temperature probe would be is best in thermal contact with the resin vat so that the temperature seen by the controller is related to the resin temperature and not just the latest puff of warm air from the heater. Eventually the enclosure would all reach the target temperature but I am sure there would be many minutes of lag if the device was sampling the air temperature, and one might start off a print with cold resin if one took the thermistor's measurement literally.

Thanks for posting this video. The other video I watched of the same design kind of skipped some of the wiring steps/explanations and even suggested using a lower amperage rating than what the heater is supposed to use. The thing I don't like about the design is the thermostat screen being inside the printer. Not only does this prevent controlling the temperature when the cover is closed (Not a big deal really.) But on the other video I watched, the blue section of the screen disappeared due to the filtering of the plastic shield. This tells me that the blue light emitted is close enough to the UV spectrum that I worry of curing the resin. Another solution to this is to add a small flip up/down shield to the design to block the light emissions.

This is a great guide, but I wish you'd touched on how you organized and spliced the wires in a little more detail. Looking at my partially assembled unit, I'm not sure how I'm going to cram all this wiring in the tiny space behind the controller.

Great video, thank you for putting this out. I did run into one issue that I'm not sure if you or anyone else has encountered. I'm I'm using all the same parts as outlined in this video, but it seems that as soon as the heater starts warming up, the thermostat cycles with an audible click, flashes 888 in both fields, and then resumes heating. It does this ever 2 or 3 seconds. Any thoughts or suggestions would be appreciated!

In brewing we have a heating element or pad and a temperature controller that plugs into the wall. A bit cheaper and no wiring. But it's not as keen.

That's quite nice design. At the end of last winter I already ordered some USB heater mat and it seems to get fairly warm, but I haven't tested it yet in my resinprinter enclosure. Still completely unknown if it needs fan to distribute heat or is it ok to just leave it in and wait. I think it's sufficient as volume is low, but gotta test. This definitely has the benefit of thermostat.

Amazing video, thanks for the tutorial! Have ordered some parts so can't wait to put it together! One question though, does amperage matter when dealing with power supply? I ordered a 2A just to be sure there'd be enough juice.

Great video, but I wonder if anyone has found a connector that can take 10A? For me 7A was the maximum I could find. Thank you

Thanks for a great tute. Very well presented and very useful. I bought an insulated dust cover (ebay USD$25) and adapted the heater to that. Works great!

Nice one, I've built 2 of these for my Saturn's and work great. The LCD displays are cheap though, and have stopped displaying some characters after a few months use...

I built one It’s Great

What is the best air flow direction? The fan keep cold air that is pushed in the heater and then in the printer or the cold air enter in the heater and then the fan extract the hot air and push it in the printer?

Very nice

This is very cool but I have one question, if you are using a power port on the heater why would you run the cable through the cover and then plug it into the heater. Why not just install the power port in the cover, you would get a more efficient seal, it would give you more room for the wiring within the heater body and the cover would not be tied to the cable making operation much easier.

Probably makes a difference where the PTC heating element comes from. Mine doesn't manage to heat the printing chamber by even 3°C in 2 hours. If you take the Amazon reviews as a comparison, this also fits with the statements of other buyers

Thanks for sharing

Hi everyone can i ask for some help? I just finished building the heater but i have an electrical problem with the power connector (it's the one suggested by VOG, where you directly wire the cables in. It heats up to the point of smoking, i can't understand where the problem is. i bought the exact same parts listed in the video. Thanks for any help.

This looks good but are the recommended connectors (shown at 05:10 ) suitable? I have these they seem to get awfully hot. edit: So personally I would not use one of the connectors mentioned at the timestamp above, it's not enough it risks a fire. I used some xt30 connectors, maybe overkill rated for 30A they're small and cheapish.

Liked the video, thanks. May I ask what is de max safe temp?

Very nice! I wonder if this could be combined into a single unit with an air filter before the fan 🤔

cool guide... bought most of the parts but what is the power supply? dont want to buy the wrong thing..
