Computed Axial Lithography (CAL) is an emerging technology for manufacturing complex parts, all at once, by circumventing the traditional layered approach using tomography. Overprinting, a unique additive capability of CAL, allows 3D geometry to be formed around prepositioned insert where occlusion light compensated other angular projections. This method opens door novel applications within multi-material systems such as endoskeletal robots. Herein, this work presents one application with...
An acoustic liquefaction approach to enhance the flow of yield stress fluids during Digital Light Processing (DLP)-based 3D printing is reported. This enhanced enables processing ultrahigh-viscosity resins (μapp > 3700 Pa s at shear rates γ˙ = 0.01 s-1 ) based on silica particles in a silicone photopolymer. Numerical simulations acousto-mechanical coupling DLP resin feed system different agitation frequencies predict local velocities exceeding 100 mm transduction 110 . Under these...
Collagen is the most abundant component of mammalian extracellular matrices. As such, development materials that mimic biological and mechanical properties collagenous tissues an enduring goal biomaterials community. Despite molded 3D printed collagen hydrogel platforms, their use as tissue engineering scaffolds hindered by either low stiffness toughness or processing complexity. Here, we demonstrate stiff tough biohybrid composites combining with a zwitterionic through simple mixing. This...
