“Manufacturing is the second largest industry in Minnesota. But these days, the way we manufacture is changing.
One example is at Minneapolis-based Tennant, a company that makes floor cleaning equipment. When testing products, they used to make aluminum prototypes. It took weeks to make just one part, and it cost about $3000. Now they use 3D printers to make plastic prototypes that cost $80 and save a ton of time.
“Before this, we were limited to one or two prototypes,” explained Tennant Company’s Peter Loring. “Now we can do a prototype every single day if we want to.”
