Ehrmann, K. (2025, October 7). Expanding Material Frontiers in 3D Printing via Multi-Material Stereolithography [Conference Presentation]. 1st Edition Conference Series on Additive Manufacturing of Soft Materials, San Sebastian, Spain.
Modern-day devices such as medical prostheses or information storage devices typically require the intricate interplay of several material properties to operate. Manufacturing of such macroscopic multi-property parts typically relies on several manufacturing techniques and corresponding engineering solutions to assemble the multi-property constructs from several individually manufactured single-property parts.
Therefore, true multi-material printing from one photosensitive resin has recently become one of the focus areas in the light-based 3D printing community. This talk will explore the advancement of multi-material printing beyond the current scope. New interpretations of the traditional multi-material printing techniques greyscale and multi-wavelength printing will be presented alongside a new technique, multi-temperature printing, to differentiate between several antagonistic material properties (hard/soft, degradable/non-degradable, crystalline/non-crystalline) in micro- and macroscale-objects.[1-3]
