3D printing on Moving Freeform Surfaces
3D printing electronics onto moving surfaces
Adaptive 3D printing is a new approach that allows 3D printing on moving freeform surfaces. The closed-loop method combines direct ink writing of functional materials and real-time feedback control to fabricate devices on moving surfaces. The hybrid fabrication procedure, which combines conformal 3D printing of electrical connects with automatic pick-and-place of surface-mounted electronic components, printed functional devices on a free-moving human hand. This adaptive 3D printing method could lead to new manufacturing technologies for directly printed wearable devices and advanced medical treatments (e.g., wound healing).
Closed-loop, adaptive 3D printing technology
Current 3D printing technologies typically rely on open-loop, calibrate-then-print operation procedures and are limited to 3D printing on planar surfaces. Previous attempts to track and ink-jet print on a moving human hand were limited to gesture tracking in 2D without compensation for the geometries of the hand surface. This new closed-loop, adaptive 3D printing technology can track arbitrary surface motions in 3D and therefore print onto moving and deformable surfaces with arbitrary geometries. This approach addresses the limitations of previous techniques by correcting, in real-time, printing errors from both the freeform geometries and the 3D motions and deformations of the target surfaces.
