Interesting idea from the UK’s Mindsets online. I haven’t found any pictures or video of the actual process or its products, so it may be one of those many brainstorms that turns out to be, ah, well…let’s just say “more interesting as an idea than in practice.” Still, I am intrigued. Feels like it could be a jumping-off point for some very clever small-shop process.

I admire the valuable information you offer in your articles. I will bookmark your blog and have my children check up here often. I am quite sure they will learn lots of new stuff here than anybody else!
I have recently posted plastic injection molding
This is an interesting idea! We’re an injection molding company and think that using a glue gun can make for some great lessons in injection molding — squirting the glue into a prefabricated piece of metal, waiting until it dries and popping it out — and perhaps bring awareness to the manufacturing process.
