Abstract Scope |
Most conventional additive manufacturing (AM) processes create an object on a horizontal substrate in a planar layer-based manner, which leads to roughed surface and weakened material strength. In the present work, conformal 3D printing algorithms based on the isothermal surface were developed and used for printing arbitrary 3D structures on freeform substrates to address these issues. The designed 3D structure can be virtually placed on the freeform substrates, and the heat spreads out through this new part. The isothermal surfaces of this created temperature field can naturally generate curved layers to offset the top surface of this freeform substrate model, and it returns tool paths for the conventional FFF 3D printing process as output. A hybrid methodology that combines conventional planar 3D printing with conformal printing, was presented. Several test cases were sliced and printed on the freeform surface to validate the developed process. |
