3D Printing Viscous Materials: Advances Toward 3D Printed Rocket Fuel, Pharmaceuticals, Cookie Dough

3D Printing Viscous Materials: Advances Toward 3D Printed Rocket Fuel, Pharmaceuticals, Cookie Dough

A 3D printed object has to be able to support the weight of its own layers, as objects that are too fluid can collapse under their own weight. That’s why it can be so difficult to 3D print with viscous materials. A fluid’s viscosity is a measure of its resistance to gradual deformation by shear […]

Collaborative Research Team Develops Bioresin for DLP 3D Printing for Synthesizing Tissue

In typical biofabrication and 3D bioprinting methods, layers of cell-laden hydrogel structures called bioinks are extruded to build functioning biological tissues. But using bioresins laden with cells, instead of bioinks, for lithography bioprinting methods, like digital light processing (DLP) and stereolithography (SLA), can be used to create patterns that are even more intricate than those possible with extrusion-based […]
