Here’s our first 3D printed prototype!
This is how an eye looks like: we chose to use magnets so we don’t have to worry about them falling every time we change face
This is the awesome online store where we bought the very tiny magnets: Animation Supplies
Thank you Design Group Italia for letting us borrow your 3D printer ❤
Here’s our recipe to make some fine looking hands!
Prepare a model of your hands with hard modeling clay, it helps if you build a little bone structure inside with wire.
Cover one side of your model with a softer modeling clay, then prepare a wall around it to cast the plaster. We used our old Legos, they work perfectly!
Make sure to use plaster for arts and crafts, not the building one.
After the plaster is dry, you should be able to peel off the softer modeling clay leaving the model of your hand untouched. You are now ready to do the second cast for the other side of the hand.
After it dries it should look like this 🙂
It’s now time to make a skeleton for your hand! Wire works perfectly, you will be able to move your model any way you want. Once it’s ready, set it in your cast and prepare the silicone.
It’s a very delicate balance between catalyst and silicone, only real wizards and witches can do it right!
This is the brand we used, apply it on both sides of the cast, keeping the wire in the middle, then put it all together and keep it close!
Just like this
After several hours you can attempt to separate the sides of the cast, it takes some muscles! To help you with this complicated task you can spread some lotion or soap between the two sides before you close the cast.
It is a magical moment when you are finally able to see your creature!
