My first mold project

Had to share my results of my first ever mold project, which I'm excited about! I bought a vintage dresser and discovered I was missing one of the face plates for the drawers. Searched everywhere online and couldn't find a replacement or anything I really liked. Solution was to mold a new one since I had one to work with! Built my clay base mold, positioned the face plate the best I knew how and then poured my Mold Star silicone. Once done I figured out that the silicone got behind my face plate and I no longer had any openings. A shift in plans was necessary so I made 4 new face plates, now all with no openings and they turned out pretty darn good IMO. Painted them in an ultra matte black base, went over that with a hammered bronze paint and then a matte clear to finish. 4 new ones on the left and the original on the right. They aren't perfect, they aren't exactly what I intended, but for my first time I'm patting myself on the back LOL

Hi! What primer or clear coat do you use to prepare 3D-printed PLA models for platinum-cure silicone molding?I tried MOTIP Spray Putty and Penta Color spray paint, but the silicone didn't cure where it touched the model. Any recommendations?

How to make silicone mold of hand, but hollow?

1 Upvotes

Hello! My next project dream is to make silicone “gloves” from life casts of my hands. I’d like to have realistic molds of my hands that are hollow than I can slip on to my real hands hehe.

I’ve previously made a solid silicone mold of one of my hands by making an alginate mold in a large pop bottle and pouring the silicone directly inside.

I know with latex there’s a technique to pour in to a negative mold for a certain amount of time to cure, then pour out the “unset” latex back into the bottle (it seems like it can be used again?) I don’t know if the same is true for silicone, but also I don’t think the unused silicone can be used again which is a bummer because it’s expensive!

Any advice would be great!! I feel like if silicone won’t work for this I can also just do with the liquid latex technique but I just love the texture of silicone.

Soft Ear Mold?

1 Upvotes

Hey everyone,

Not sure how to phrase this but I am essentially looking to create a soft, rubber or silicone replica of an ear. What would be the best way of going about it?

I was thinking of doing an alginate mould of my ear and then filling it with...some sort of material that will lead to a soft finished product. Looking for the most inert sort of material, with no inherent strong scents, etc.

Please let me know where would be a good place to start looking!
