2 Microstructures (2 of 2) (IMAGE) Optica Caption This shows two microstructures made with the new material, containing the highest concentration of RDGE. Left: Pre-charring. These pyramid and bunny models did not respond to the preferred method of 3-D shaping, so they were created using an alternative process. Right: Post-charring. Notice that the pyramid and bunny shrink significantly less than those made from the material with a lower concentration of RDGE. Credit Credit: Optical Materials Express.
