A cell 3D printer

Abstract

A cell 3D printer is disclosed. A shaped cell-containing stent is accurate and clear in shape, and free of stagger among layers. The cell 3D printer is suitable for printing tissue/organs having high shape requirements. According to a technical scheme, the cell 3D printer includes a spray head mixing and spraying a cell-containing gel precursor solution and a calcium ion solution, a material supplying system supplying the spray head with the calcium ion solution, a pneumatic control system controlling spraying action of the spray head, a workbench supporting the cell-containing stent printed and shaped, a liquid discharging system for discharging a liquid accumulated in a tray of the workbench, and a driving system for allowing the spray head to move at the X, Y and Z directions relative to the workbench.

AI Technical Summary

Benefits of technology

This patented technology allows two different solutions (gel material or liquid) from separate sources are injected into one another through an extrusion gun that forms tiny fibers called catheters inside each fluid stream before being deposited onto the surface where they will be used to create 3D structures made up of these materials. These techniques allow for precise control over how well the resulting structure looks like it should look good when placed back down after manufacturing processes.

Problems solved by technology

This patented technical describes how current techniques used to create tissue engineered materials have drawbacks including difficulties controlling their microstructures due to blockages caused by pores or other gaps within them. Additionally, they require complicated processes like mixing collagen solutions together before adding cells to the material. These issues make these techniques challenging when trying to achieve high precision and accuracy in producing specific types of tissue constructs needed for medical applications.
