Printing Outside the Box: Realizing Multi-Functional Products with Multi-Modal Additive Manufacturing Process Chains
Additive Manufacturing’s (AM) layer-wise fabrication approach empowers engineers to selectively place (multiple-) materials to realize products that satisfy multiple functions and design objectives. However, to fully realize this potential, AM processes are in need of further advancements in material selection and process capability. To address this need, it is necessary to tailor both the materials for the unique constraints imposed by AM processes, the processes for the unique properties of the materials, and novel post-processing approaches to reach the desired performance.
The aim of this talk is to highlight how multi-functionality can be achieved by expanding our view of AM processing to expand outside of the printer’s box to incorporate post-processing to impart additional functionality to printed parts. Examples covered in this talk include (i) AM of copper foams via binder jetting, (ii) printing of hybrid electronics via photopolymerization of fully-aromatic polyimides, (iii) and autonomous robotic AM of mechatronic systems.
