(outdoors it allows for water to drain though it, and it's very durable and non-slip.) i never did this myself, but it's not gonna take a lot of resin. maybe 5% .. 10% max by volume. a thin, even coat should be preferable, to any resin starting to pool at the bottom of the mould.

In the past I have used the vacuum chamber which worked very well. I used a two part resin on high voltage electrical circuit boards. The resin had about about 2 hours working time in normal conditions but set in about 30min under vacuum. A couple of tips use a container about three times the size of the amount of resin, as it "grows" a lot under vacuum. Place a sheet of blue towel under the container to catch any overflows and release the vacuum slowly. If you are going to try solid moulds (metal) heat the mould before pouring in the resin as it helps the resin flow but shortens setting time. If the mould has a small opening to pour in the resin make sure that you have a hole to let the air out otherwise you can get bubbles.

Thank you for taking the time to explain everything in detail! 👍🏼 I'm a hands on learner who benefits from a face to face instructor in a workshop... but I feel confident enough to try this because of your teaching method. Awesome videos, alot of content creators skip the additional effort to explain so thoroughly. For example, as soon as you said mentioned a vacuum chamber I was nervous , but then you immediately elaborated: What kind you should need, how to find it, and how to use it, I felt an instant sigh of relief! I'm not sure if you have any other videos specifically, on chemicals you are familiar with/work with, what the applications are for each type, how to order/purchase and how to properly use them in the sense of product quality and safety. Thank you, keep up the great work! 🙂

Great tutorial. I could have used this years ago. My brother in law and I were making custom 10" He-man figurines. We used this same process to copy the master model. I would take a plain 10" articulated figure, and use Sculpey to sculpt the armor and other details. It would take several cycles of sculpting, then baking the figure, then doing more sculpting to get a final, fully detailed product. Once we were happy with it, we would set the figure half covered in non-hardening modeling clay with alignment pins/tabs. The whole thing would be surrounded with heavy cardboard taped in place. We would then spray a mold release on the part. After that dried, we would pour the two part RTV into the mold and de-gas it in a vacuum chamber made from an old fish tank (really thick acrylic). The rough surface was smoothed down with a torch just like you did. Once that cured, we would remove the non-hardening modeling clay, apply more mold release, pour more 2 part RTV and re-run the vacuum process. After curing, the cardboard was removed and the two molds separated. The master would be removed and put aside to make more molds. Depending on the molded item's shape, we would then carve air passages into the mold as well as an angled funnel. The mold would then get a cleaned with soap and water, dried, then coated with more mold release. To make a part, one mold half would be taped off around the outside, covering the funnel and any air passages. The mold would then be mostly filled with a 2 part either silicone or poly based resin. The resin would be allowed to start to tack off. Then, depending on the part, either a plastic or metal piece was placed into the mold and pressed into the tacky material. The air passages and funnel would be cleared out, and the second mold half would be affixed into place using tape to seal it off. The mold would then be filled completely through the funnel and placed into the vacuum chamber for degassing. The mold would stay under a slight vacuum until the resin would be mostly cured. For ease of mold release, the resin could not be allowed to be fully cured. The mold would be opened, and the item removed. This would leave us with a solid colored part. If it had a metal frame, the part would have been molded with a resin called dragon skin. Dragon skin is semi hard and very durable. The metal frame would allow the part to be moved, so parts like arms and hands could be manipulated into various positions. The plastic frames would be molded in a more traditional, but less expensive resin. The plastic would let the part have give, but great strength for parts like the torso and legs. The parts would then be hand painted, assembled, and serialized. These would sell for anywhere from $200 to $800 depending on the figure.

Mix your batch in a container that'll fit into the vacuum chamber, don't make a habit of pouring a batch directly into the pot. Be aware and leave about 1/2 the container empty to create room to rise in the vacuum pot. That's also wildly too much rubber, 1/2" thick is plenty for most applications. Since that's easily over $100 worth of rubber it's ideal to use corrugated plastic for retaining walls using the corrugation to your advantage to make it easy to shape the wall to fit about 1/2" off the part. Use hot melt and add gussets on the outside to support it against hydraulic pressure. Finally, if you can use water against your pattern without damaging it, pour water in to 1/2" over the highest point of the pattern, then pour it out and measure to calculate the volume of rubber necessary. Mold release isn't necessary in a silicone mold, but it will make it last longer, and remove parts quickly after curing to save the surface from baking out prematurely. Casting resins that take longer to cure develop less heat and are easier on the life of the mold.

NP. Hand casting is an old model making and prototyping technique, and used heavily in the entertainment industry. A lot of aftermarket parts for automotive and other hobbies are initially hand cast until outsourcing becomes necessary. 3D software, 3D printing / CNC, and hand casting are the holy trinity of DIY. You can cast materials with properties that rival thermoforming polymers used in "real" manufactured goods these days. SmoothOn is ideal for getting a wide variety of user friendly materials in realistic quantities. Subbed.

Vibrating molds will help with bubbles!

Im thinking something like desktop router where base or side plates are casted with all screwholes include etc Ive seen something fimiliar years ago, if remember correct, there was 3D printed hollow "case" which they filled with fine cement, Print had all screw holes etc for rails and other parts which was so nice for assemling

How much does the silicon cost for the mold and the resin ?

I'm sorry if this is a dumb question, but how do you clear the silicone out of the vacuum chamber after the fact? Does it just peel off when dry?

lol great sound releasing the mold. BTW I learned that iso will release hot glue when doing that style of mold box.

@@ActionBOX Oops, haha, my coworkers and I just say iso usually for isopropyl alcohol. It releases the hot glue from melamine or other plastics quite well, so you can reuse the mold box walls easily. I've been binge watching your videos the past few days, really loving the projects!

Thank you so much for showing this process. I was just thinking today about how silicone is poured. I wish I had come across your video earlier. I filled my CNC table with silicone before putting on a Saunders plate. I just tubed it layer by layer. I don’t have a vacuum chamber so that would’ve been an additional expense, but then I would’ve been able to pour silicone so… 😂 great channel!
