In keeping with the College of California, Davis, researchers have received the David Dornfeld Manufacturing Imaginative and prescient Award on the Society of Manufacturing Engineers 2024 Nationwide Science Basis Manufacturing Blue Sky Competitors with a proposal for a pathway to 3D printing contained in the human physique. The challenge earned prime prize over 5 different finalists, chosen out of greater than 50 submissions.
The Blue Sky Competitors seeks interdisciplinary proposals for visionary concepts that could possibly be described as radical, outrageous, transformational, or breakthrough; they need to ‘pose grand challenges to be addressed by pursuing a producing analysis imaginative and prescient… and present potential for transformative affect.’
Of their proposal, titled ‘Printing past limitations: A pathway to non-invasive deep inside physique printing’, Mohsen Habibi, an assistant professor of mechanical and aerospace engineering at UC Davis, and his UC Davis collaborators, Aijun Wang, a professor of biomedical engineering and surgical procedure, and James Marcin, a professor of pediatrics and vice chair for pediatric medical analysis, recommend utilizing Direct Sound Printing, or DSP, to 3D print issues like implants or scaffolds contained in the human physique and cut back the necessity for invasive surgical procedures.
The novel 3D printing technique, which Habibi found in 2018, makes use of sound waves, as a substitute of sunshine or warmth, to create strong materials out of a polymer resolution from behind a bodily barrier.
For 3D printing contained in the physique, the researchers suggest utilizing biologically suitable supplies, which might be injected into the physique and the ultrasound supply can be spatially adjusted to print the specified form.
