So you love 3D printing, but you don’t love the limited height for your projects. The Deltaprintr High Resolution 3D Printer ($625) is looking to open the door to making taller 3D prints. The Deltaprintr features minimal set-up, 100 micron resolution, and expandability. All you have to do is buy longer aluminum extrusions to increase your build volume. Every printer comes with an automatic calibration probe and an LCD display as well.
