Thought I would print the first draft of our dog food file on our library’s 3D printer. Took my eldest daughter to watch and learn about 3D printing. This was the third time at the library trying to get this file to print. Thought this was going to be the day! But alas no, the printer would dispense the liquid plastic onto the molding plate, but it wouldn’t stick to the molding plate. So it would mess up the mold. Tried to adjust the molding plate, clean it down with rubbing alcohol, but kept having same problem. Gave up after 1 1/2 hours.
