A team at the Massachusetts Institute of Technology (MIT) has unveiled a novel approach to manufacturing intricate nozzle arrays using 3D printing. These triaxial electrospray emitters are designed to dispense multiple liquids simultaneously, allowing for the creation of precisely layered, solidified droplets.
Historically, the complex design and microscopic tolerances of such emitters have necessitated production within semiconductor-class cleanrooms. However, the MIT researchers have demonstrated that a standard vat polymerization 3D printing technique, similar to those used in dentistry, can fabricate these devices. This breakthrough allows for the creation of arrays containing 16 nozzles within a roughly one-square-centimeter area, complete with their complex internal liquid pathways.
The development is significant because it drastically reduces manufacturing complexity and cost. These 3D-printed nozzles are expected to be more efficient than conventional designs, producing more consistent and customizable droplets. Potential applications span a wide range, including pharmaceuticals requiring layered formulations, the creation of self-healing materials, biosensors, contrast agents for medical imaging, and specialized coatings for solar cells and implants. The researchers suggest this could significantly boost production rates for these advanced products.
