6-axis 3D Printer (video) #3DThursday #3DPrinting

Professor Yong Chen and students created this 6-axis 3D Printer work-in-progress at USC:

Here is a video of a 6-axis 3D Printer using Parallel Kinematics driven by KFLOP that Professor Yong Chen and his students Xuan Song and Yayue Pan created over at University of Southern California.

From the team:

“Most additive manufacturing processes are layer-based with only three-dimensional motions in the X, Y and Z axes. However, there are drawbacks associated with such limited motions, e.g. non-conformal material properties, stair-stepping effect, and limitations on building around inserts. Such drawbacks limit the applications of additive manufacturing in many areas. To enable 6-axis motions between a tool and a work piece, we investigated a Stewart mechanism and developed a low-cost prototype system for multi-directional additive manufacturing including the Fused Deposition Modeling and CNC accumulation processes. The technical challenges in our development are the hardware design, coordinate transformation, platform constraint checking, movement simulation, tool path generation, and part fabrication. Several test cases are also presented to illustrate the capability of multi-directional additive manufacturing processes.”

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. What further improvements? This is perfect!
    A point of inquiry, though, is this printer only available
    for small-scale projects, or can it also be used for large-scale models?

  2. Very impressive, but, a DC motor on the extruder instead of a stepper? Touchdown at the 5-yard line.
