AcoustoFab is pioneering advancements in 3D printing technology by enabling the integration of multiple materials and functional components directly during the printing process. Our sound levitation technology demonstrates the lifting, moving, and placing of both solid and liquid materials without physical contact or attached robotic arms. This approach allows for the interleaving of ingredients in different states, such as solids and liquids, making the process material-agnostic, while overcoming limitations such as contamination and restricted motion associated with traditional robotic structures.
The inclusion of functional materials like ferromagnetics and electronics during printing facilitates the creation of multi-functional products. This innovation is particularly beneficial in industries such as aerospace, automotive, and healthcare, where complex parts with diverse functional properties are in high demand. Additionally, the ability to embed sensors, conductive materials, or magnetic properties directly into products reduces the need for manual assembly and enhances the overall functionality and value of the final outputs. Our technology offer a sustainable solution by reducing single-use plastic waste from consumables like pipette tips, syringes, nozzles, and wasted resin.
By targeting sound pressure at a resin, we have achieved localized bubbles in resin. By enabling targeted local bubble creation through sound pressure, we are able to shape any bubble pattern like ‘A’, ‘B’, numerals or figures in resin, paving the way for the next phase of industrial printing. By the printing of bubbles in various shapes within resin during the printing process, we have achieved porous material fabrication with tailored stretchability and flexibility. By customizing porosity and incorporating multi-material printing, AcoustoFab expands additive manufacturing capabilities significantly.

The implications for automation, robotics, chemical handling, biomedical life sciences, and 3D printing are profound. This innovative approach addresses current limitations while setting a new standard for sustainable and efficient material processing.
