In the present work, prototypes of polymeric cantilever-based magnetic microstructures were fabricated by means stereolithography (SL). To this end, a UV-curable system suitable for high-resolution SL-processing was formulated blending bifunctional acrylic monomer with photoinitiator and visible dye whose content tuned to tailor resin SL sensitivity. Subsequently, confer ferromagnetic properties photopolymer, two different strategies implemented. A two-step approach involved selective...
Drop‐on‐demand inkjet printing of highly viscous fluids represents a attractive emerging technology for advanced material deposition. The jetting inks, such as concentrated polymer solutions and nanoparticle suspensions, is key enabling many industrial applications, ranging from microelectronics to biomedicine ceramics manufacturing. Currently available standard printers typically operate in relatively narrow viscosity range (up 16 mPa s), alternative drop‐on‐demand techniques (such...
