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 10 μm level cab be fabricated
• Layer thickness can be optimized to 5μm level so that staircase effect can be eliminated with continuous exposer of UV projection.

Major Raw materials Utilised:

• Aluminium for fixtures and sheet metal for enclosure Vibration isolation system Linear slide and DMD DLP light engine with suitable optical components.

Major Plant Equipment and Machines required:

• CNC milling machine and a turning centre, Grinding machine, Clean room class 1,00,000 with compressed air supply for assembly and process validation. Clean bench for rinsing the micro parts.

Techno economics:

• In India, polymer based micro 3D printing is an emerging technology. Currently macro 3D printers are widely available around the globe but micro 3D fabrication technologies are not available due to complexity of process and high development cost. CMTI is only the technology developer in India for polymer based micro fabrication to cater various industry needs. The SUKSHM 3D micro fabrication system can realise the complex micro parts at very low operation and maintenance cost.
