Professor Yong Chen von der University of Southern California, erzeugte mithilfe seiner Studenten einen konzeptionellen 3D-Drucker, der danke seiner 6-Achsen auf unregelmässigen Untergrund drucken können soll.
Für die Steuerung des Druckkopfes, verwendet dieser 3D-Drucker einen kinematischen Antrieb, der mittels KFLOPS Elektronik von Dynomotion angesteuert wird.
TBD Development of a Low-Cost Parallel Kinematic Machine for Multi-Direction Additive Manufacturing
Xuan Song, Yayue Pan, Yong Chen, University of Southern California
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 discussed including 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.
