Title of the Innovation: SUKSHM 3D microfabrication system

Brief About Innovation

SUKSHM 3D microfabrication system can realize the complex micro parts at very low operation and maintenance cost. The overall system comes with control software along with mechanical and electrical drawing and Fabrication parameters for general purpose and biocompatible resins

Salient Features:

The revolutionary micro-fabrication system enables complex 3D ultra-fine solids to be made in a short time by means of spatial light modulation technique.

• A UV-curable resin having a hitherto unachieved resolution is cured at a super-precision resolution by a high-precision digital light exposure mechanism.
• 3-D structures are created by the layer-by-layer forming method, under which 3-D ultra-fine solids are formed automatically by repeated light exposure and resin coating.
• Ultra-fine Features down to 10μm level cab be fabricated
• Layer thickness can be optimized to 5μm level so that staircase effect can be eliminated with continuous exposure of UV projection.
