3d Printed Molds for Plaster or Concrete - Boil Molds 

I’m eager to try out this technique at some point. I’ve found a reusable silicone substitute in the form of making agar molds that are beautifully compatible with plaster. After demolding, the agar can be remelted to make subsequent molds. I usually can only get one casting out of the molds but I love being able to just re-melt the mix. The other recipe I use is less compatible with plaster and better for water based clay, but you can get multiple castings from each mold and then also remelt the material for subsequent molds - this utilizes glycerin and gelatin. Thank you for sharing your techniques, I’d love to be in touch!

Thank you for your tutorial. I'm looking at this method for casting a component for a project, and had no idea how to work with plaster. You have saved me a lot of time and pointed in the right direction!

Nice video, I enjoyed it a lot. I will try some of your suggestions to improve my 3d printed molds for plaster and concrete. I look forward to your new videos.

Great tutorial . Lookin forward to the next one on cores. Please keeps it going !

I would love to know about how you use a core to avoid undercuts and to create a hollow.

Very nice video!

Very good

You ever try "firing" the clay casts in a Microwave Kiln, the plaster outer case with a layer of Silicon carbide on the inside. The Silicon carbide absorbs the microwaves and heats whats in the kiln. they are usually used for glass.

Is it okay to pour and make a mould on a 3d print plastic directly for ceramic clay?

Which 3d printer do you use?

Did you use plaster of Paris?

where can I found those candles/house sculptures?

To dry plaster mould you could use microwave
