    Default Mold making

    I'm looking at designing a bunch of parts to vacuum form. My first mold I made by copying the part and performing a boolean of the shelled part on the mold part, cutting off the shell. This was slightly involved, and while the resulting mold is usable for this test part, the changes won't be ideal I think for other parts.

    Are there other ways of doing this operation that I should be looking at? I suppose I could be looking at using a female mold instead of male, it is after all the outside I'm interested in having controlled after all, but I'm wondering if there's a way to get a good male mold.

    You can use a female mold for vacuum-forming; it's just a little more complicated, since you need to use a top sheet over the hot plastic to force it down into the concavities. But why isn't your positive form satisfactory?
