I've been trying to figure an easy way to make stuff without injection molding, and when I saw you put the concrete mold in the oven... Literally blew my mind, so simple but I never thought of that. Thank you, great video.

much more simple/cheap than the silicone molds i was looking at before. great video!

When my dad was in high school, I'm 52, he made a 2 piece plaster mold. He then painted it and cast parts from wax. He then made a 1 piece mold with plaster from the wax piece. He then took the mold to his metals shop in school and poured molten aluminum into it. He never tried to remove the wax, just poured over it and it burnt out with metal replacing. Hid it before teacher seen and let it cool. He would just break the mold away, remove the sprew, and sanded it. I seen 1 pair of the brass (aluminum) nucks he cast in school.

Thanks for this. Some other plastic recycling videos make it look so complicated, so this video is much appreciated.

Smart well spoken great instructor...Thanks and God bless you sir...

CARDBOARD! Yay.. my hero. I do have cardboard and I can gorilla tape the hell out of it and cement is cheap and easy to get. No machine shop necessary. THANK YOU.

Right On Ma Man! You took the guess work out of what plastics are best used for what I'm trying to create, thanks!

Thanks for the education. This will be useful in my scratch builds.

Funny how I came up with this method a few days ago and this video just confirmed that it will work.. thank you .. now I'm really gonna try it

Hey I been bouncing around on KZread looking for ideas on my project. Your idea is beautiful. I would also like to suggest the vacuum former method. Basically, all you need is a box to stick a vacuum in, with a mesh top. You sit your model on top of that mesh. Then you create a frame/border to hold a PVC sheet with, above a stove or some heat source hot enough until the plastic start sagging. Then you can quickly set that heated plastic sheet on top of the model and create an accurate mold of the model. I hope this helps someone.

Awesome man, thanks for the idea!

Nice video. I have many plastic bottles that I would rather use to make my own products than just throwing them away. I'll check out your other videos.

very helpful, thanks slim

Concrete, cool, I would try to make it a little finer, though. I have thought of using plaster of paris, but I think it will be too fragile. I have been wanting to make clothespins from recycled plastic since the ones you can buy are either wood or really cheap thin plastic that busts apart in the sun in a year or less. I think this could work. I may have to grind the slots for the springs with a dremel, or just saw or file. Concrete wouldn't support really fine bit of the slot, but otherwise, clothespins are pretty basic. I can use wood ones for a model and use the springs on the new recycled plastic ones. I have some ancient plastic ones I might want to use for models, too. Save all my old springs and make new clothespins!

great tutorial. i love it

Cool. Great method.

Great tutorial. Only thing I'd do different, is use a scrap 2x6 or wood from the scrap pile or firewood to carve out the original design, then spray with cooking oil, or release spray. Nice designs for the slingshots. I wonder how much weight a 1/4 inch thick sheet of plastic could hold?

Thanks for this cool idea.

Thank you for this! I’ve been looking for a way to mold recycled polypropylene without having to buy a ton of equipment, and this is the first video I found that uses such a simple method. Just one question though- Will it be safe to use already-fired clay for the mold or will it explode in my oven?

What if you put pergamentpapier on the sides of the concrete mold so the plastic doesn't get into it and, eventually, doesn't break it when you remove the platic piece? Could this method prevent the mold from breaking and make the plastic piece easier to remove?

Great tutorial. This has motivated me. 9:19

With this method you can use it one time

what I do is on the stove with a spare butter knife to give things shape and push them together, maybe gripper, and elses (usually harder and higher melting point) to push it against and cast its shape on it. allows me to be more liberal and it’s quite fun also, modify the stove: if possible, instead of the lid thingy, alluminum foil piece to concentrate the gas into one stream its so sad that, unless blue flame you’d get the soot on it :((

Nice.

is their anything that can be added to the PLA melting process that will make the PLA melt with a more LIQUIDY pourable viscosity... ALSO MUST REMAIN AQUARIUM SAFE ?

would it be possible to use a normal oven for this? I have some ideas for molds that wouldn't be able to fit in a little toaster oven like that

Cool man thanks. Just have a mess of things around that could just be wasted...

Would it sticc to dirt if I poured it in that way an just sand a lil dirt if needed?

You can get high heat resistant silicone so make the sling shot the same way with cardboard only maybe smooth it out with sulfer free clay n pour the silicone as you did the concrete, cutting the plastic in to smaller pieces will make for a cleaner less bubbled result.

Certain types like clear plastic (containers or pop bottles) don't melt this way and they turn white and become extremely brittle. These two types are the easiest because they harden like they were before melting.

@@selfentertained1932 yes...I do realize the final plastic part has to be detailed. What i'm also pointing out is that the inner sides/walls of the concrete mold are harder to reach with whatever tool you use/need to make them smoother.I find it way easier to approach/look at a piece of material from the outside. So when your plastic piece has been kicked out of the mold, 1st ,it is lighter than concrete to handle, 2nd, plastic is easier to shape than rock. a dremel rotary tool would work great for that... Pretty neat the way you started with a piece of paper, then cardboard,then wood,to end up with concrete..thumbs up..
