The Robo 3D R1 fully assembled 3D fused-filament-fabrication printer has a partially open frame for fabricating parts up to 8 x 9 x 10 inches (H x W x D) using 1.75-mm ABS and PLA filament (sold separately). It can also use other materials including t-glase, laywood, HIPS, and flexible filament. The all-metal hot end has a maximum resolution of 100 microns. The 10″ x 10″ square print bed has an 8.4″ x 8.4″ square heated portion to prevent uneven cooling and warping of the printed part. The printer comes with software that automatically calibrates the machine and levels the print bed to ensure precise prints, and it connects to the computer using the included USB cable. Using an SD card (sold separately), the printer can be disconnected from the computer after initialization for untethered printing during long print jobs.

The machine runs on an Arduino MEGA 2560 microcontroller uploaded with the latest Marlin Firmware and has a RAMPS 1.4 shield. The printer head moves in the X (left and right) and Z (up and down) axes, while the print table moves Y (backward and forward) axis. The machine uses NEMA 17 motors, and the frame is made of injection-molded plastic for prolonged life. The printer includes a sample spool of filament.

*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Fused filament fabrication printers build prototypes and parts directly from computer-aided-design (CAD) data sources by stacking layers upon layers of molten material. The print material is provided in filament or wire form and is fed through an extruder within the print head, similar to how ink is used in a standard printer. A printer with a single extruder can print using one filament at a time; a printer with dual extruders can print with two different materials or colors at the same time. The thickness of the printed layers can be customized for each print, but the thinnest layer that a printer can lay is called its maximum resolution. Choosing to print using very thin layers will create parts with more detail, but will typically take longer to print. To lay the material in the correct way, the print head and bed typically move in a combination of X-axis (left and right), Y-axis (forward and backward), and Z-axis (up and down) movement.
