Abstract
Described are techniques, systems, and methods including those employing multi-channel controlled pneumatic printheads which contain a linker (e.g. Luer lock), a designed functional system (e.g., a microfluidic system, coaxial system, bi/tri-axial, or a mixing system), and one or more outlets (e.g., nozzle part or output linker). The printheads are useful for pneumatic, pressure assisted, extrusion-based 3D printing and emulsion/mixture evaporation for fabricating particles that may encapsulate an active pharmaceutical ingredient or live cells into a biocompatible polymer.
Claims35
A method comprising:
- providing a first component to a first linker of a plurality of linkers of a printhead;
- providing a second component to a second linker of the plurality of linkers of the printhead;
- contacting the first component and the second component in a fluid mixer of the printhead;
- forming a mixture of the first component and the second component in the printhead;
- and
- printing the mixture from the printhead through one or more outlets.
