Impact Printing (2024-11)¶

Impact printing is a novel robotic additive manufacturing construction method enabling the controlled high-velocity deposition of discrete extruded dense materials parts. This particular additive manufacturing method is developed specifically for circular and sustainable materials, such as excavated materials. . The AM process and custom tool is developed for multiple construction scenarios including off-site prefabrication and onsite in situ robotic construction with autonomous construction machines. Preliminary results suggest that this method may be more efficient than 3D printing, requires minimal supports and no custom formwork, and may require less stabilizers and enable higher height buildup per day due to relatively higher initial yield stress during initial material deposition.
