Basically i have this toothless model i will 3d print..im planning to make a silicone mold over it...but its like a rlly complext shape💀 anyone think its possible? And if it is, can someone advise me on what to do (rip my sanity)
I've done some molding and casting with platinum cure silicone, but for the first time the curing has failed with the surface remaining sticky goop. This is the first time I've used platinum cure silicone on epoxy clay painted with acrylic paints, which leads me to assume one or the other is to blame. But which one?
The epoxy clay was Apoxie Sculpt, and the sculpture is roughly a year old, absolutely totally cured. It was also fully painted using Vallejo acrylics, so there would be no direct contact between the epoxy and the silicone. That makes me suspect the paint rather than the epoxy, even though I haven't had this problem with painted plastic.
What I do know is the silicone itself hasn't gone bad, because there was some left over I used to make a skin texture mold from an old face cast. It cured well within the expected time, as did the residue in the mixing cup.
I am looking to build a food grade silicone cap which would need to sit on top of a plastic container. The plastic container is sourced through Alibaba - so a standard size. The plastic container is a deodorant dispenser, and a balm needs to be pushed through the cap so the balm can be spread on the face.
Don't have the design of the cap, need help with design and print - is there someone here who can help me?
Hello!!
My friend and I did several attempts of trying to make a half face life cast with alginate and trying to figure out where we went wrong.
The first try I think we didn’t use enough alginate (sort of just used enough to cover face) and also let it dry before adding the plaster, and let each layer of plaster dry in between (and did about 4-5 layers of plaster) Once the plaster dried we tried to take it off and the alginate just completely fell apart and also out of the plaster cast.
The next two tries ended up somewhat similarly with the alginate mold being very wet (which might be normal??) but also flimsy and falling to a few pieces and not staying in with the plaster cast. We tried using more alginate but might have messed up by putting more alginate on after some had dried already?
We are thinking that the solution might be to just use a TON of alginate right at the beginning and starting with the plaster right away after that.
Wondering if anyone had any suggestions to help!! 🙏🙏🙏
We are planning on using hydro cal in the alginate negative mold after wards, then creating another negative mold with either more hydro cal or plaster of Paris? Then finally pouring a liquid latex into the negative mold to make a realistic mask!!
Going to be casting in silicone, most recommend vacuuming on the directions. I won’t need anything huge. I’ve heard/seen people buy just the lid attachments? Are these better/worse? Is there a brand I should avoid? Thanks for reading.
Not sure if this is the right place, my gf has these spiral earrings. One broke and she asked me to make her new ones with resin. I can't for the life of me figure out the best way to mold this rounded spiral and be able to get it out once it's done. Any advice?
Am I able to pour more in at another time to complete the mold, or do I need to let this cure, and completely start over?
Hi all.
Thank you in advance for reading and assistance with this.
I’m trying to find resources to learn how to make mold boxes like in this photo, but the only thing I’m finding is links to a program.
I’d really like to learn the skill myself rather than buy software. Does anyone have any experience with this or any videos/tutorials?
I have been on a ceramic break for a few years and am ready to dive back into it! I wanted to make a plaster mold for pressing clay in from the impression of my kids' hands.
To make the negative of this plaster mold, previously I would have used liquid soap, a mixture of green soap and sunflower oil I believe. But soap apparently is not so good for the plaster as it dissolves it. What is a good release agent that keeps the gypsum and its detail most in tact?
How should I store my silicone molds between uses? I have been told that they should not be stacked on top of one another. I have a lot of molds. Thanks for your input!
I should have bought quick dry cement instead of normal concrete but I'm really happy with how it turned out. Looks and feels like it's made out of beach sand!

I learned today that alginate lifecast molds are only going to last less than an hour before they start to shrink and deteriorate, which throws my plans off since I stupidly planned to lifecast everything I needed for projects this year and next. Some alginate molds I will be pouring silicone directly into to get my final, others I will be putting monsterclay in. I don’t have a ton of monster clay and I don’t feel like buying more (expensive) and I can’t buy all my silicone all at once (also expensive). My master molds will be ultracal so I cannot use that to make a positive. What else (preferably on the cheaper end) can I immediately pour into my alginate lifecast so I have a positive to then make an ultracal mold for in the future? Or would it be easier to make my alginate casts the day I need them? Thanks for reading!
I recently tried on a pair of stethoscopes for the first time and the tips hurt my ears, it felt like it was pushing my earwax all the way in (for context I never wear earphones, only headphones.) I was thinking of making a custom molded tip for my ears with an amazon ear plug making set. Does anyone have any experience with something like this or advice please
does anybody know of something like Free Form Air, a culpable epoxy ”clay“, but that is stronger and adheres to epoxy/fiberglass better? I find fixes with free form air always break. thank you!
I’m after a bit of advice if possible, I’d like to make some replacement tyres and I’m planning on using Vytaflex 45/50. Now these won’t be used for running, only display purposes, the car is from the 80s so far too fragile to use anyway.
Now my worry is the detail in the tread, I’m thinking, should I just treat the mold like casting anything else with detail and fill that first. I’m also worried about being able to fill all the detail before it starts setting. I have a pressure chamber so not worried about bubbles and I have cast car badges before with detail but nothing like this

Hi everyone,
I'm looking for a manufacturer or mold maker who can create custom chocolate molds based on my brand logo/design.
The mold needs to be made according to my exact dimensions and specifications, with high precision and clean detailing so that the final chocolate accurately reflects the design.
If you have worked with a company or individual who specializes in custom chocolate molds, I'd appreciate any recommendations. Ideally, they should be able to work from a design file and maintain precise measurements.
Thanks in advance!
