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 […]
