As much as 3D printers have evolved in their short history, they still tend to look like they were made for hobbyists, by hobbyists. You'll see boxy frames, sometimes with exposed parts -- and you may have only limited help if something goes awry. Solidoodle isn't happy with these intimidating designs, so it's launching a fifth-generation peripheral (the Press) that's kinder to first-time users. The 512-cubic-inch printer comes in a friendlier, enclosed design that looks more like a mini fridge than the raw machinery of Solidoodle's previous models. The spool is protected to prevent plastic filament jams, and the printing bed automatically calibrates itself -- you won't have to adjust it every time it's uneven.
