Ž . Micro-stereolithography mSL is a novel micro-manufacturing process which builds the truly 3D microstructures by solidifying the liquid monomer in a layer by layer fashion. In this work, an advanced mSL apparatus is designed and developed which includes an Ar laser, the beam delivery system, computer-controlled precision x–y–z stages and CAD design tool, and in situ process monitoring system...

Recoating in a stereolithography apparatus (SLA) involves dipping the part being built into a vat containing liquid resin and sweeping a blade over the top of the part. There are two problems with the recoating operation in existing SLA systems. Firstly, the process is slow because the blade sweep speed is usually restricted to minimize disturbances to the resin surface and also because, after ...

Since its inception in 1984, 3D printing has revolutionized manufacturing by leveraging the additivity principle and simple material–energy coupling. Stereolithography, as pioneering technology, introduced concept of photopolymerization with a single photon. This groundbreaking approach not only established essential criteria for additive processes employing diverse localized energies materials...

Surgical guides produced by stereolithography use hard resin. The hard resin prevents seating beyond the height of contour, hence these guides are not intrinsically retentive. By covering the guide with a flexible thermoplastic material that extends into the undercuts, the resulting guide now has a retentive feature. This allows it to maintain its position during surgery yet it can easily be re...

The use of rapid prototyping (RP) technology for rapid tooling and rapid manufacturing has given rise to the development of application-oriented composites. The present paper furnishes succinct notes of the composites formed using main rapid prototyping processes such as Selective Laser Sintering/Melting, Laser Engineered Net Shaping, Laminated Object Manufacturing, Stereolithography, Fused Dep...
