3D PRINTER
One of the most useful tools I have acquired and recommend are my two 3D printers. It allows rapid part prototyping as well as the ability to quickly make a tool. In this case I had a cam bearing that my two other cam bearing tools just weren’t working well for. I quickly drew it up in CAD and in the time it would take to dig through the scrap pile and make one in the lathe this plastic one was finished. I have used them to make bearing & bushing drivers, sheet metal dies, flow bench inlet guides and a lot of other odd stuff that would take a minimum of days to get if you’re lucky enough for it to be made.
