Professor Christophe Moser and his team of scientists at Ecole Polytechnique Fédérale de Lausanne have unveiled a groundbreaking technique in 3D printing that enhances the quality of printed items without the need for magnifying projected patterns. The paper published in Light: Advanced Manufacturing introduces a new approach to fully volumetric additive manufacturing (VAM), moving away from the conventional layer-by-layer process. By harnessing this innovative VAM technology, the researchers have paved the way for higher-quality 3D-printed objects that could revolutionize various industries. In their paper published in Light: Advanced Manufacturing, the team introduces helical tomographic VAM, which significantly improves the quality of 3D-printed items without magnifying the projected patterns. By off-centering the light modulator and continuously translating the resin vertically along the patterned light beam, this new technique allows for the fabrication of larger, high-resolution objects up to 3 cm × 3 cm × 6 cm. The breakthrough holds great promise for various industries, including dentistry, where cm-scale objects can be individually manufactured with increased precision.
The research team advances 3D printing technology and presents new high-resolution, high-speed fabrication options. As helical tomographic VAM continues to evolve, it can revolutionize industries such as dentistry, enabling the production of custom-made, cm-scale objects with exceptional accuracy and efficiency. The novel technique opens up exciting opportunities for diverse applications in industries where precision and individualized manufacturing of larger objects are paramount.
