Step 1
I've found in an art shop a "natural" powder that you can use to do a mold "BioTestThing"

I decided to reproduce the little sculpture i had 3D pritned for an other assignement
The amount of water needed was not that clear but after many trys, it ended whith a 40% powder and 60% Water, but at the end it was to liquid

Step 2
I decided to reproduce the little sculpture i had 3D pritned for an other assignement

I inserted the sculpture in the mix and when it was dry i took it out of the mould


I used plaster and a vaccum pump, and plaster can jump

Or grow as a blob

Then

I was happy with the result


Step 2
I would like to test a milled model with a funny matérial
I drew a test object i wish to mill and mold
