Houston-based Re:3D is making 3-D printers that are big -- really big: their Gigabot printers (the largest has a build area of 269,040 cubic cm) aren't meant for desktop hobbyists, but they're priced low enough to be reasonable wishlist items for schools or makerspaces. They're also based on open standards, and open source (see last year's Kickstarter project). I got a chance to see one of them on the floor of OSCON (still with plastic wrap on the panels, because it was actually a customer machine making a show-floor pit stop before delivery), and was impressed with the fridge-sized cabinet. One cool design constraint that Founder and Chief Creative Officer Katy Jeremko told me about: despite appearances, it's sized to fit through standard household doorframes.  

If you're in range of Houston on Wednesday, June 15th, you're invited to the company's 3-D printing open house: come check out all kinds of printed projects (though you can expect an emphasis on the company's own products). They promise snacks, too.
