New laser-based volumetric additive manufacturing method can 3D print glass in seconds
Versatile and ubiquitous, glass is increasingly found in specialized applications such as fiber optics, consumer electronics and microfluidics for “lab-on-a-chip” devices. However, traditional glassmaking techniques can be costly and slow, and 3D-printing glass often results in rough textures, making them unsuitable for smooth lenses. Using a new laser-based Volumetric…
LLNL's Huban Gowadia named to State of Alabama Engineering Hall of Fame
Lawrence Livermore National Laboratory’s Huban Gowadia has been inducted into the state of Alabama’s Engineering Hall of Fame (EHF).
