Bioprinting is a 3D printing technique used to build synthetic tissues or organs using live cells and some form of scaffolding material. Stem cells have been found to differentiate into different cell types based on chemical signals as well as mechanical and chemical properties of surrounding biological materials, tissue(s), organ(s), etc. Several different cell types, properties, and structures are often required even within a single given tissue type or organ.
Sonaer nozzles allow one to gently and accurately spray solutions containing cells onto pre-existing substrates, or, utilizing multiple hypo-needle feeds or a DMF setup, and robotic coating system, one may be able to print both cells and scaffolding controllably during the same print, with the ability to run multiple solutions at different flow rates, print speeds, timing, etc. and potentially produce structures with multiple materials, complex shapes, and different cell types.
Sonaer designed a hypodermic delivery method for introducing solutions to the atomizer tip. The hypo delivery method shown has only a single line but can be made with up to 20 lines around the circumference helping to combine reactive solutions to be atomized. Gas or air is injected through the center of the nozzle for focussing purposes. Device is great for building structures from droplets.
Sonaer pin point spray attachment for introduction of slurries and solutions for building bio compatible scaffolds. Device attaches directly onto 60 or 130KHz atomizer nozzles.
