I am glad you went to so much detail to make this a manageable reality for my non-conforming 3d printer project. It really was the biggest challenge as standard heated beds for anything beside the ubiquetous chinese printers just won't do. Well done and many thanks for your ingenuity and sharing. Cheers
you know I didn't think about that until you just said it - but yes one big advantage is the heater can be painted on a non standard surface - cheers for that mate and glad I helped
Excellent mate. I will be trying this to work as a heated bed and enclosure on the 3D printer I use for the graphene impregnated polycarbonate material. It needs a print temp of around 400C, bed of 130C, and around 100C in the enclosure reducing slowly once the print is done so it doesn't crack. What I have works, but the temperature has been a bit less than uniform making for a fair bit of waste. This should smooth things right out!
I missed the " SOFT PLAY AREA " the first few times around. Good one I'll have to borrow that one! Thanks for this one I need to repair, replace the heater on my stirrer. Just paint it on and go.
It’s amazing it sticks to Teflon so much for non stick I heard years ago it gives of very poisonous fumes when heated to high but I don’t know what temp probably above 200 Great share as aways😃

This temperature range of 200-250C is perfect for 3d printer beds for some of the high temperature polymers developed by NASA! Parts made from this material are as strong as steel and highly sought after, which makes them very expensive!
Brilliantly simple and very neat Rob, one question I am always frustrated with wasting paint (ink) cleaning brushes then waiting for them to dry etc when doing small jobs on a regular but not continuous basis. As your ink is aqueous-based can you just bag the brushes in a plastic bag for a day or two between uses?
11:00 you will have better thermal readings if you put a thermal pad there. Also, in hindsight, the copper tape could have been pre-tinned, so heating up a pre-tinned wire next to a pre-tinned tape would give a nicer solder joint.
That's fantastic! Teflon electrical insulation and heat conductivity, and a paint on resistor (heater.) Very clever! They say nothing ever sticks to Teflon, There's no reason for the paint to chip or warp from contraction and expansion, is there? Of course you can use touch up paint to fix it, right. Is 14.4 watts enough heat on each plate? 5 amps for all 4 at 12 volts. ... 24v is better ... 57.6 watts but 10 amps for all 4, watch your wiring connections for hot spots. 14 gauge?
It should be fine and it is in a protected - yet accessible - position - but you are quite right it spot fixes easily with another dab of paint. I am not sure of the gauge of the wire it's rated for 5amps - which is plenty in this application
How many Watts are plates operated? What are you using as a power supply is it ac or dc? As Ink thickness is controlling the resistance, how uniform is the thinness? At what current does the ink start to fail? At what temperature does the glue on the copper tape fail? Have you looked at the hot plates with a thermal camera?
Great stuff Rob, you continue to knock then out of the park, (American slang). How does your paint perform under high UV exposure and extremes in temperatures? For example minus 30C to the heating temperature of your hot surface at 85C to 110C.
@@ThinkingandTinkering I didn't think you would have tried to determine those type of issues. We will work on that here on our side of the world. I will keep you posted. Cheers mate
Have read that PTFE can emit toxins from 200C onwards - might be safer with non-teflon trays. This info from a Prusa forum post titled 'PTFE max temp on a routine basis': "The pyrolysis of Teflon starts at 200 degrees-C and proceeds slowly up to 420 degrees-C; at 500 to 550 degrees-C, the degradational weight loss reaches 10% to 5% per hour, respectively, depending on conditions. In the temperature range 300 to 360 degrees-C, hexafluoroethane (C2F6) and octafluorocyclobutane (C4F8) were identified as decomposition products. In the range 380 to 400 degrees-C, octafluoroisobutylene (also C4F8) could be detected and, at 500 to 550 degrees-C, the chief pyrolysis products other than tetrafluoroethylene (116-14-3) (C2F4) were hexafluoropropylene (116154), (C3F6) octafluorocyclobutane, and octafluoroisobutylene plus a complex residue of perfluoroolefins. Inhalation toxicity tests indicated that the octafluoroisobutylene gas, the most potent product, was approximately ten times as toxic as phosgene (75-44-5) Ref: Toxicity of Pyrolysis Products of "Teflon" Tetrafluoroethylene Resin by Zapp JA Jr, Limperos G, Brinker KC. Proceedings of the American Industrial Hygiene Association Annual Meeting, Cincinnati, Ohio, April 26, 1955."
Hmm... *Teflon tube* is a pretty common material. If the outside can be coated, it may be of use in some continuous fluid-material processes. Now i'm wondering if it could make a rudimentary 3d printer hot-end/extruder that doesn't use any metal. Because it's a flexible tube, a Peristaltic pump could even be incorporated onto it. Anyway, some ideas for everyone.
Great work Robert, very interesting concept. have you found any difference in performance, if your paint strokes went with the electrical flow or across the flow?.
you could of found this easily... soft play area lol "Generally speaking, Teflon is a safe and stable compound. However, at temperatures above 570°F (300°C), Teflon coatings on nonstick cookware may start to break down." "PFOA is a chemical that was previously used to manufacture Teflon. It has been linked to health conditions such as kidney and liver disease. However, all Teflon products have been PFOA-free since 2013." "polytetrafluoroethylene (PTFE), commonly known as Teflon is now a synthetic chemical made up of carbon and fluorine atoms." apparently fluorine and related atoms make good graphene oxide addatives so turn a potential soft play area problem into a benefit down the garden shed option, krank it up mate :-D so hotter than your oven, good enough to hinge two trays together and do pcb reflow work, add an arduino/esp32 ramp,hold,and cooling scale data graph html page if you like... reflow some plastic into useable sheets, burn some toast crack an egg white over it and so make nitrogen doped carbon foam overnight off that pv charged battery sitting doing nothing right now... oc if you have some cheap £2 Cooling Peltier Plate Thermoelectric Coolers handy, you could also make the *freeze dried reduced GO foam (with salt water electrolyte) version, and use the toast ( aka nitrogen doped carbon foam) as your insulation. after robert already did this long ago ,strange *"Binder-free reduced graphene oxide 3D structures based on ultra large graphene oxide sheets: High performance green micro-supercapacitor using NaCl electrolyte: Journal of Energy Storage,Volume 21, February 2019 "A high capacitance of 618.15 F g−1 at a current density of 3.0 A g-1 is obtained. •Optimum energy and power densities are 42.92 W kg−1 and 1.35 kW h kg−1, respectively."
Craig G. Lewis - yes It’s pure genius. Just think - packaging made of a super capacitor that upon opening heats the contents to a specific temperature by discharging through its own outer layer ... granted that would be a one shot process but wouldn’t have to be - pots and pans that literally only require a 12v. power Source no stove top required - with the right materials as a substrate viable 12v ovens etc. A Teflon and graphene ink thermal layer in a space suit. Again you could be working the super capacitive element into that design all controlled via a micro controller interface ... or even just thermally regulated hunting jackets or underwear... Viable Solar powered heating systems... The possibilities seem endless. I’m wondering how far the graphene based solar power generation has come along... Just some ideas - but seriously it’s this type of experimental application that opens up developmental applications that are only limited by the imagination.
@@deepforrestalchemy9189 Yes this is the future. Already have the process for mass production, Heating pads and Greenhouse films. Get some funding set up a system. @Robert, we should set up a discussion in the Members channel.
@@ThinkingandTinkering funny enough : ) "burned toast" is a VERY good carbon insulator. blend up some moldy bread, and/or add a tiny amount of fresh live yeast and required stiff base insulater material (bread mix style)with your ink , and paint a thin/thick layer on the layered stack heater trays until they rise to your given required thickness allowing for shrinkage later, then zap to the heat to kill the yeast and continue to carbonise and insulate a given space with very little tidy up
Is that paint flexible after it dries? Or does it crack after it's dried and flexed. That would be a very interesting property if it is flexible. Might be an interesting ability to have in a different formulation if it isn't. Wink wink, know what I mean? Grins mate.
teflon is a trade name for PTFE and that melts at 327 degrees also this is cookware most domestic ovens go up to 287 degrees centigrade and domestic gas ovens can go up to 537 degrees centigrade - so to be honest - I doubt it - I was thinking of the carbon it burns off at 400

I'm thinking of putting in a Tesla battery in my 28 ft. RV. It's a 24v, 5.3 Kwh module, which I already bought on Ebay for $1,250 us. It will need a simple heating system and control circuit so the module could be charged in the winter if the temp's got below about 2 c. . You'll destroy a Li-on battery if you try to charge it below 0 deg. C. so it needs to be insured against that. With this ink and a bit of temperature control magic it could do the job nicely, I suppose. I just might use the money for a heating pad and apply it to some paint and use that to make an electric heater for the battery bank . I also been " what if'-ing" the possibility of making a dedicated electric bread baking oven for baking bread in my RV.. Instead of using propane to heat my RV oven to bake bread. Being a nut, I would like to try (experiment) making a highly insulated (to reduce heat loss/costs) bread baking oven. If this ink set up right would make 180 c. inside an enclosed, minimally ventilated, insulated enclosure that should bake bread nicely with minimal energy usage. Of course one never knows how an idea will work if one never tries a "what if idea", Right? Look for my order for some paint. Best wishes.

It will need a simple heating system and control circuit so the module could be charged in the winter if the temp's got below about 2 c. . You'll destroy a Li-on battery if you try to charge it below 0 deg. C. so it needs to be insured against that. With this ink and a bit of temperature control magic it could do the job nicely, I suppose. I just might use the money for a heating pad and apply it to some paint and use that to make an electric heater for the battery bank .
I also been " what if'-ing" the possibility of making a dedicated electric bread baking oven for baking bread in my RV.. Instead of using propane to heat my RV oven to bake bread. Being a nut, I would like to try (experiment) making a highly insulated (to reduce heat loss/costs) bread baking oven. If this ink set up right would make 180 c. inside an enclosed, minimally ventilated, insulated enclosure that should bake bread nicely with minimal energy usage. Of course one never knows how an idea will work if one never tries a "what if idea", Right? Look for my order for some paint. Best wishes.
@@rickdees251 you are spot inmate a lot of what if can only be answered by doing - you have sparked an idea though - I have an old oven and.`I could convert it with the paint - you ok if I do that as it was your idea really - cheers - Rob
Dear Robert Murray Smith i have a question about wast water and how to mange it im making a screen printing washout booth filter system and i was wondering if you would have an idea on how to improve and make a working device that could purify the waste water before it goes dow the drain im going to use water based ink and photo emulsion on the screens the diy systems that is out there dont look safe to me sorry but what do you think?? would it make sens to use a sand filter with activ carbon or somthing in that sens??? Sorry for being of topic but a huge admire off your work mvh Lasse Askhøj Anderen SunTurtleCamper.com
sorry fogot the dimensions h 1900mm* 820mm* 440mm space under wash out area 470mm* 770mm* 420mm could modify unit if more gravity is need then it would be 2100mm* 820mm*500mm top reservoir as big as the plastic sink 90 l bucket www.silvan.dk/murerbalje-90-liter?id=2640-5725349 maybe make a filter on the side like this would it make sens?? sorry video little long just skip true to get idea ruclips.net/video/ffZxFBLQzaY/видео.html and would it be safe to send down the drain or what do you think??
Hiya mate - I am sorry but I really don't know the answer here - water remediation is a pretty complex subject, expensive to do well and full of quirks specific to the application. Sorry about that
@@ThinkingandTinkering i know... to make something like this small scale is a big challenge ruclips.net/video/tFr_70x5e-c/видео.html how would one get rid of hydrogen safely living in a flat really dangerous think i will try to make a filter instead to take the different substances out of the equation this is the system that is in use today ruclips.net/video/S3G1wa3zEOs/видео.html but thanks for the input im doing a crowdfunding campaign for a solar powered rv its open source development i would like to invite you and your team to participate in solving some of the challenge but im just getting started and the donation button and shop is not redy jet + legal stuff and permits mvh las
@@sunturtlecamper4256 at your own risk oc, and i assume you know to keep h2 away from oxygen/air and flames for safety... depending on how much h2 you are generating ...
as a side note, bubbling near pure hydrogen through few layer nano carbon powder helps make it magnetic..
iv not reproduced his experiments but engineering logic seems to agree that lowering the direct oxygen/air to hydrogen ratio contact while burning the gas works in a safe manner, as in his super simple "sand heater" ruclips.net/video/Bd_yrSldFWw/видео.html
Heating with Hydrogen HHO or Hcat. This man does just that.

oc as Okki Moeljadi found out as a side effect, surrounding your small hydrogen generator on demand tank with water is very good safety practice to as it helps contain accidental explosions and again reduces getting direct oxygen/air contact while its flash burning... so perhaps add a water heat exchanger around any "sand heater" design
