PhD Defence - Hossein Safari Mozajin

Imagine you could create a detailed 3D object, like a small sculpture or part for a machine, in just a few minutes instead of hours. My PhD research focuses on improving a special 3D printing method called Tomographic Volumetric 3D Printing, which uses light to build objects all at once instead of layer by layer.

This technology works by shining patterns of light from different angles onto a liquid material, which hardens to form the object. I developed a new way to make this process faster, bigger, and more accurate by combining multiple light projectors and advanced computer calculations.

The result is a more efficient way to print complex objects that could be used in areas like healthcare, where doctors might need custom medical devices, or in manufacturing for quick production of unique parts. This research helps bring us closer to a future where 3D printing can be faster, more flexible, and widely accessible.
