Development of a hybrid thermoplastic forming process for the manufacture of multi-facet and curvilinear surgical blades from bulk metallic glass
… forming processing involving sequential micro-molding and micro-drawing operations is developed to manufacture the multi-facet/curvilinear geometries found on most surgical blades. This is accomplished through an oblique drawing technique, i.e. drawing with a non-zero inclination angle. …

Demolding of hot embossed polymer microstructures
Polymer-based microfluidic "lab on a chip" technology promises to reduce cost and extend access to medical diagnostic tests that formerly required expensive and labor-intensive lab work. The predominant methods for manufacturing these devices are miniaturized molding processes including casting, …

Investigation of defects on acoustic scattering in cloak by molding process
For this paper, molding- and casting-based microfabrication of metal microstructures was developed in order to replicate the acoustic cloak. The metal was cast into a stretchable PDMS mold, which was cast from micromachined aluminum cloak. For the PDMS mold, the mold release agent, trichlorosilane …

Modifizierung und Prozessierung des rekombinanten Spinnenseidenproteins eADF4(C16) zur Steuerung der Interaktion zwischen Zellen und Seidenfilmen
… wurden mittels Mikroabformung in Kapillaren (micro‐molding in capillaries, MIMC) strukturierte Seidenfilme mit parallelen Rillen hergestellt. Im Vergleich zu glatten eADF4(C16) Filmen konnte die Zelladhäsion auf den so hergestellten Filmen signifikant erhöht werden. Durch die vorhandene …

Engineered microneedles for transcutaneous vaccine delivery
… to the skin. We have utilized laser ablative micro-molding of poly(dimethylsiloxane) to generate bio resorbable poly(lactide-co-glycolide) micro-structured skin patches bearing -100 micron-scale needles arrayed across their surface. Upon topical application, these 'microneedle arrays' are able …

Development of a hybrid process for manufacturing surgical-grade knife blade cutting edges from bulk metallic glass
… process integrating thermally-assisted micromolding and micro-drawing has been developed for producing BMG surgical-grade knife blade cutting edges with edge radii <25 nm. A hybrid process testbed was designed and used to successfully run tests over a range of the key process variables. …

Uv-liga Compatible Electroformed Nano-structured Materials For Micro Mechanical Systems
UV-LIGA is a microfabrication process realzed by material deposition through microfabricated molds. UV photolithography is conducted to pattern precise thick micro molds using UV light sensitive materials, mostly SU-8, and electroforming is performed to fabricate micro metallic structures defined …
