An unusual sound fills the once silent space. On the main floor of the Fine Arts Library at the University of Texas at Austin, a 3D printer softly whirs.
Tim Zawistowski stands over the printer, trying to create a miniature tree for a model he's building. Someday, the sophomore hopes to design lighting and projections for live events. Today, though, his dimensions are off, so he heads back to his computer.
"I'll add another 5 millimeters, and it will be good," Zawistowski says.
