Toaster Oven to Burn Out Kiln? 3d print to Metal Cast 

Thanks for watching! Should I do a recast even bigger?

14:48 - Whoa, failed cast or not, that is some incredible detail.

So much information, great video. I will definitely be making my own

I feared for the electronic components when i saw you put it atop :) I hope to see a perfect intricate cast soon !

Interesting. I would finalise your toaster oven build with it upside down. As you said, heat rises, so it makes sense to me to have the delicate electronics below the heat. Great idea though

Would have been super awesome if you showed how you wired it up step-by-step

There's a good chance that the device didn't come calibrated or is calibrated to use a different thermister than what you're using. I know the little programmer I got for my DIY enclosure heater has a sequence you put it through to calibrate the temperature so it wouldn't be surprising if your device had one as well. If all else fails, you could put a separate thermometer you trust next to it's thermister to get a comparison.

Great project! I will certainly upgrade mi electric oven. What kind of plaster you use?

Awesome video! What investment powder are you using? Also, what's your printing setup? I've tried casting using ApplyLabWorks cyan castable resin and I haven't gotten great results. I was also using R&R Advantage, but I was thinking about trying Plasticast since it's designed to handle the expansion of resins. Any advice?

Would I be able to keep my quartz triac heating elements when using this temperature controller (I wouldn’t need them to get hotter than their current capabilities).

Kudos to you ! I won't miss my rarely used toaster oven I guess LOL Google "burnout oven" and find few choices at jaw dropping cost. Then again you are buying a small kiln. But really $4000??? Was very surprised that you could reproduce any of the mesh like feature of your skull and thought it unlikely that filigree like structure could burnout without leaving residue and clogs. PVB or PLA? I gather that pre-heating the investment mold is key to good result, still I figured that you would need vents. Perhaps the plaster is somewhat porous. The density of brass versus aluminum must be a factor for gravity feed pours. Anyhow, I am trying to make a decent go at casting some sea mammals for aquatic diorama. I have a 250mm long dolphin as my first project. Even at this scale the pectoral and tail fins are extremely delicate and based on my results to date, are bound to be the lion's share of the challenge. They have to be perfect. I imagine me with my mig welder trying to re-attatch a broken flipper. Support structures will have to manually be applied rather than leaving it to Cura. Some 6061 T651 aluminum alloy scrap I have been holding might be useful for yielding a more durable model but eventually I am going to have to acquire some proper ingots of A380 ? or maybe even melt down cans. In Canada there are no suppliers of ingot that I am aware of that cater to the hobby or start up. U.S. supply is expensive and many just don't ship here period. Regards

Is there a way to run coils through it to avoid haveing to replace the heating element

Do we have to have a burning out kiln? But I don’t see anyone trying lost wax casting without kiln, can we just use torch to melt the wax and pour?

What type of plaster do you use? The one I used always cracked

So how many burnouts has this toaster oven done so far? I want to do some lost PLA casting but the cost of the burnout kiln is a big impediment.

You already spent enough money to buy a brand new burnout oven man!!! 😂😂😂

but does it take all day?

Props to you, but you should probably disclaimer this. Somewhere there's a better idiot who's disabling a safety thermocouple to cook his toast faster....

I bet that the PID will have melted down by now...?

When all said and done it’s worth your money to just buy a purpose built burnout oven.

If you guys see how I used to do it back in Cuba which is a communist country, Im talking about third world shit, I used to put the flask, which was just a copper pipe cut, on top of just and electric furnace with an aluminum pot on top, for 5 hours straight, and then cast in a centrifugal casting 😂
