News — Charging forward at top speed, a garden snail slimes up 1 millimeter of pavement per second. By this logic,  researchers’ new 3D printing process speeds past existing methods — at a snail’s pace.

Researchers in Beckman’s  created “growth printing,” which mimics tree trunks’ outward expansion to print polymer parts quickly and efficiently without the molds and expensive equipment typically associated with 3D printing. Their work appears in the journal .

“Humans are incredibly talented at making things. Completely new manufacturing processes are hard to find. Growth printing is entirely new, which is thrilling,” said  , a professor of mechanical science and engineering at the  and project lead.
