Researchers have developed a low-cost 3-D bioprinter by modifying a standard desktop 3-D printer, and they have released the breakthrough designs as open source so that anyone can build their own system.
Researchers have developed a new process that combines 3D printing and casting. In additive freeform casting (AFFC), first a shell of the part is manufactured using FLM printing, then this shell is filled with a two-component resin. This saves time, increases stability of the part and allows new materials to be printed.
Scientists report that they have developed a powerful printer that could streamline the creation of self-assembling structures that can change shape after being exposed to heat and other stimuli. They say this unique technology could accelerate the use of 4-D printing in aerospace, medicine and other industries.
Combining two different polymer forms can switch manufacturing of silicone parts from molding, casting and spin coating of simple forms to 3-D printing of complex geometries with better mechanical characteristics and better biological adhesion.
