Abstract
The state of research and technology in the field of Additive Manufacturing (AM) with Two-Photon Polymerization (TPP) focuses on stacking individually printed planar layers to create the desired geometries. As a result, benefits known from other Multi-Axis AM (MAAM) processes, such as printing on non-planar surfaces, are unexplored. Even though there’ve been endeavors in creating systems which go beyond the 2.5D approach, these lack the range of motion required to transfer many benefits of MAAM to the TPP process. This contribution provides a kinematic concept for a TPP MAAM system with at least three translatory and two rotatory degrees of freedom. To ensure the transferability of MAAM concepts to the TPP process, the system is required to provide a range of motion that is similar to that of existing MAAM systems. To limit the design complexity of the system, it is destined for the specific use case of printing aspheric micro optics. The presented concept details a blueprint for creating a five axis TPP kinematic print system, thereby providing a basis for the further advancement of TPP printing by enabling multi-axis curved layer printing.
