Study of layer orientation on the fracture behavior of two additively manufactured thermoset resins, A
… range of applications. Specifically, the role of print orientation on the quasi-static and dynamic fracture response of two distinct AM polymer materials, DA-3 and PM-EM828, is presented. While predictive simulations often leverage quasi-static fracture criterion, impulsively loaded cracks can …

Microfluidic diagnostics from continuous liquid interface production additive manufacturing
… repeatability but with somewhat lower accuracy. Print orientation significantly affects the accuracy and repeatability of the process, and the best accuracy is achieved when the microchannels are parallel to the direction of motion of the build tray. We demonstrate manufacturing, assembly and …

Improving surface quality of SLA 3D printed parts via controlled dip-coating
3D printing is useful for rapid prototyping, and is quickly becoming an option to aid in mass manufacturing, whether to make low-volume molds for injection molding and thermoforming or to make unique fixtures. 3D printing via stereo lithographic apparatus (SLA) builds parts by curing photopolymer …
