This Delta 3D printer kit originally started as a campaign on Indiegogo in 2012 and raised an impressive 777% of its initial target goal of $10,000. Since then, the Rostock MAX has only increased in popularity, and it's without a doubt one of the coolest looking machines out there with its insect-like structure. The main selling point of the Rostock is certainly the Delta style robot system instead of the traditional Cartesian style used by most other desktop 3D printers. This design offers a far higher printing speed and positioning accuracy than other machines, a factor that results in smoother curves on finished prints. The build volume is one of the largest of any desktop printers (assuming that you can place the one-meter-tall printer on your desktop) with 270 mm in diameter and 375 mm in height.
