Mold with Inner Structure

Postby Captasty » Thu Dec 22, 2016 3:17 pm

Hello,

I am looking to cast a 3D print I will be making soon. It is a square shape with an inner cross shape. Think a cube with a hole in each side going all the way through to the other side. I am very green in molding and cannot quite determine the best way to make a cast of it.

I just don't see how to remove the model once cast because the cross shape locks it in.

Thank you
Nick

Here is a link to two photos of the rough structure. http://imgur.com/a/vyaPH This will be most likely be a rubber like material. Poles will be inserted into the holes, so a 2 part mold that is glued would most likely not be strong enough.

Thank you.

Whilst that is castable, it would require a complex mould. I wouldn't even attempt it, personally.

would it be possible for you to print the piece in two halves, and then just fit them together after? That would be much easier to cast.
