Back in May, I took an inventory of all the 3D printers at the Bay Area Maker Faire. Today, I did the same for Detroit and found about twelve 3D printers here (I may have missed a couple). The MakerBot crew is here, fresh from a week at Comic-Con. I was also pleased to see SeeMeCNC from Goshen Indiana here. Their H-1 printer (with injection molded parts to keep the price down) looks really great.
