From: Rapid manufacturing of micro-drilling devices using FFF-type 3D printing technology
Manufacturing process for the plain-type MDD without blades. (a) 3D printing the ABS casting mold with 0° blades using FFF-type 3D printer; (b) Polishing the rough mold surface using cold acetone vapor fumigation process, (c) Inserting the polished ABS mold into uncured PDMS mixture and degassing PDMS; (d) Curing the PDMS mixture; (e) Separating the PDMS mold; (f) Pouring the UV curable resin into the PDMS casting mold followed by degassing process, and inserting the neodymium magnet; (g) Curing the resin using UV lamp; (h) Separating the MDD from the casting mold.
