What about a heavy, metallic weight? Maybe coat it in silicone as well so it doesn't sticky to the casting….
I used this method to make high temp silicone moulds with my Mono x Resin printer to cast Pewter pendants
I've never had great results by using the rice measurement technique. But I will say that you will get a lot closer by using it as a way to measure volume, not weight.
Silicones vary in weight and for a weight measurement to work your silicone would have to weight the same as the rice. Go with volume. You'll get better results.
But it'll still be off. lol
If you really wnat to reuse PLA waste perhaps you could put the plastic chips into a bucket with holes or mesh in the bottom, so when they melt fully they drain out the bottom into the mold? or just melt it in the bucket and stir until fully melted and just pour it. you'd probably have to melt it in temperature stages so that it doesn't scorch.
Hey uncle Jesse! Love the video! I just bought my first elegoo saturn s. I'm super excited. What would be the best resin and settings for it?
Pressure cookers often require water in order to build up pressure, that water and vapor may interact with the melting plastic, which we all know doesnt like humidity. Plus most pressure cookers only apply a max of 15 psi, which has a temperature of 257 F (125 C if you are using imported water), as opposed to the normal 212 of water boiling at standard pressure.
This is more than many filament's glass transition temperatures, but lower than their melting temperature and considerably lower than nozzle temperature.
Estimate of chance of success is low.
I would recommend instead a vacuum chamber to be used as soon as the plastic comes out of the oven. Get them as hot as possible to make them liquid, then simply suck all the air out. Note, design a mold with a raised edge to account for the expansion of the liquid and bubbles while under vacuum. Chance of failure due to the filament solidifying due to taking too long and the drop of temperature from a decrease in pressure. Make sure to repressurize once the filament starts to thicken.
Also note, when making a mold, use a volume instead of weight to determine how much resin and or silicone is needed, it is more accurate as rice has air gaps and is a different density than resin and/or, and those materials often have a variety of densities across brands
You really should get a vacuum chamber to de-gas the silicone. Oomoo is nice in that you can get by without de-gassing it, but you still get little bubbles on the part that have to be cleaned up.
@UncleJessy Just a heads up if you go to cast a resin print, make sure to do a small test with the molding first. Some resins have sulfur in them that, prevents the molds from curing, and I know how expensive those silicone molds can get 👍
The only problem Unci-Jesse is that they are ONE (1) PART MOLDS (!)*
(* I.e. Meaning when you CAST them: One side will require a ton of clean-up/sanding etc. & won't be formed to the design of the Mold.
Ideally You want a TWO PART MOLD (OR even 3 Pt. Mold: that's how 99.9% of things we buy are made)
Maybe it would be better to cast resin prints that would be awesome
Elegoo discontinued the Neptune 3….
To know how much silicone you need for the mold you could just take the 3d printed piece and put it on a scale, tare it, and fill it with water. Much more precise and quick, and doesn't waste rice
Why did you use FDM instead of SLA for the molds negatives? Wouldn't that help eliminate layer lines in your final result?
Would it be possible to melt the old filament separately, something like a kiln, and then pouring the liquid into the molds to then cure?
Those look like bubbles released out of the silicone itself. Notice how you have zero bubbles on top!
It's a thermo-chemical reaction. Either due to some mold release or again, because of the silicone itself.
Low degassing silicone is a must in this case, or proper degassing before use. You should try with preheating.
Wishing everyone a happy new year and looking forward to the amazing 2023 with all of you. Be well be you
The moment that I saw people melting scraps into silicon molds the FIRST thing I wanted to know was how to make my own molds. Thanks!!!
Great video! Especially loved the part where you used rice to measure the volume of the mold🤣I would have used water, but it seems like rice works too lmao
Kinda funny to think that you make a mold for a mold. My sister wants me to make a mold, but worry avout how no filament is flexible enough to make a mold. Thought of making one on a video resin printer, but it's currently not plugged in and there is no room to do the possessing. But this right here is perfect. Going to try this out. It's a mold for candle wax by the way.
Why not melt everything down into the mold like you did and then before pulling it out put some resin in there and let it fill in all the holes? Stick it in a vacuum chamber to pull out the air. You'll use a lot less resin as the scrap pla will fill up a lot of the volume.
I wonder if there was some kind of out-gassing at the mold surface that created the bubbles. The top was nice and smooth. I'd be interested to see if this worked out better the second time. If the bubbles are smaller, it may be helpful to run the molds through a heat cycle before using them.
Something else occurred to me last night. The mold release. Is it meant to be used with hot casting or just cold casting. like resin. It could be flashing to a gas causing the bubbles also.
I can't believe how many 'pressure cooker' comments I had to downvote. Sad. Very sad.
Spray paint these matte black and it would look a lot like lava rock
You need to do some titty molds!!! lol
