Home Depot came out with the news this week that they are featuring 12 brand-new 3-D printers in selected stores around California, New York and Chicago. They will have a whole staff dedicated to teaching customers on how to use the printer, and will even help you create little mementos to keep. This is seen by some as a risky venture for Home Depot, as it doesn’t seem to be the correct market for such an expensive technology. On the other hand this might draw a big crowd, curious to see how the new printers work. These will be available for sale both in the selected stores and online. There will be about four MakerBot models to choose from retailing from$1,300 to $2,900.
