Description

Droplet generating device and method

The present invention relates to a droplet generating apparatus and method, and more particularly to a droplet generating apparatus and method suitable for use in a solution containing a biological factor.

3D printing, also known as laminated manufacturing, the American Society for Testing and Materials classifies the forming technology of laminated manufacturing into seven types: First, Material Extrusion, Second, Sheet Lamination, Material Spraying Material Jetting, V. Photopolymerization (Vat PhotoPolymerization), V. Binder Jetting, Powder Bed Fusion (PBF) and 7. Directional Energy Deposition Directed Energy Deposition (DED), etc.

In recent years, 3D printing technology has developed rapidly, and its application fields include industrial design, product verification, medical and aerospace industries. Among them, in the application of the medical industry, such as the production of medical equipment and artificial bone materials, the adhesive spray molding technology is often used. The main concept is to uniformly and tightly lay the powder material on the working plane and spray through the molding solution. The powder material is adhered to the powder forming zone and stacked layer by layer to obtain a finished product. If the molding solution contains biomolecules, it can directly or indirectly promote cell proliferation and differentiation, and thus contribute to the recovery of the patient.

However, the molding solutions for the commercially available 3D printing system do not contain biomolecules, so that it is possible to rapidly drive the droplets of small size to be molded by piezoelectric means. However, the molecular size of the solution containing the biological factor is large, and the viscosity of the solution is relatively high, so the piezoelectric side cannot be used. The drive drives tiny droplets, which in turn affects the size and accuracy of the model after molding. Other droplet formation methods include pneumatics such as dispensers. The dispenser uses a collision to instantaneously pressurize the nozzle to generate droplets. Since the striker directly contacts the liquid material, the more the impact, the higher the temperature of the liquid material, and thus the biological activity of the molding solution containing the biological factor.

Therefore, it is necessary to provide a droplet generating apparatus and method suitable for containing a biological factor solution.
