The present invention relates to the technical field of 3D printing apparatuses, and in particular to a piezoelectric spray head of a 3D printer and a working method therefor, and also to a 3D printer. A spray head inner cavity of the piezoelectric spray head of the 3D printer is formed in the shape of a cone with a tapered radial dimension, and the portion of a feeding hole that is close to the spray head inner cavity is formed as a throttling portion. Therefore, the piezoelectric spray head of the 3D printer can reduce the flow resistance of a liquid printing material and the energy loss caused by the feeding hole, and can thus improve the spraying ability of the piezoelectric spray head, such that the 3D printer with the piezoelectric spray head can be used for the printing of a biological material with a high viscosity, effectively avoiding the problem of nozzle plugging. Additionally, a forming chamber of the 3D printer is formed with a circulating air duct structure, air sucked in by a fan in a forming zone can be circulated in the circulating air duct structure, and the air can be refrigerated and cleaned during circulation.

An reinforced electrospun fibrous membrane comprises: an electrospun fibrous membrane body and a plurality of reinforcing thread sets fixed to the electrospun fibrous membrane body via through holes on the electrospun fibrous membrane body, wherein any two of the plurality of reinforcing thread sets are parallel to each other; each of the plurality of reinforcing thread sets comprises a start end and a termination end, both being connected to an edge of the electrospun fibrous membrane body; each of the plurality of reinforcing thread sets comprises an reinforcing fibrous thread comprising at least one main thread and one auxiliary thread respectively arranged at a front side and a bottom side of the electrospun fibrous membrane body and configured to cross each other at the through hole. The embodiments provide reinforced mechanical performance by adding the reinforcing thread sets on the reinforced electrospun fibrous membrane, ensuring a mechanical strength necessary during tissue movement, while being easily folded or rolled into other shapes. The reinforced electrospun fibrous membrane is prepared by adopting a degradable material, which can be gradually absorbed during inducing new tissue formation and provide room for the new tissue formation.

Abrégé

Disclosed are an artificial dura mater and manufacturing method thereof. The artificial dura mater includes electrospun layers prepared by electrostatic spinning, at least one of which is a hydrophobic electrospun layer. Further, above the hydrophobic electrospun layer, there can be at least one hydrophilic electrospun layer. A transition layer can be further included between the hydrophobic and the hydrophilic electrospun layers. Additionally, cytokines and/or medicines can be affixed to either or both of the hydrophobic and the hydrophilic electrospun layers, by way of bio-printing. The disclosed artificial dura mater shows good biocompatibility, enhances dural tissue regeneration, achieves excellent repairing effects, prevents adhesion, allows complete absorption, has good mechanical properties, ensures low infection rates, and can be loaded with therapeutic agents.

Abrégé

Disclosed are an artificial dura mater and the method for manufacturing the same. The artificial dura mater consists of electrostatic spinning layer by electrostatic spinning. The electrostatic spinning layer has at least a hydrophobic electrostatic spinning layer. And there is at least a hydrophilic electrostatic spinning layer on the hydrophobic electrostatic spinning layer. A transition layer is formed between the hydrophobic electrostatic spinning layer and the hydrophilic electrostatic spinning layer. Cytokine and/or medicine can be blended with every layer of the artificial dura mater，furthermore, can be adhered to the hydrophobic electrostatic spinning layer and/or the hydrophilic electrostatic spinning layer by cell printing technique. The dura mater has a characteristic of good biocompatibility, accelerating the regeneration process of its tissue, excellent repairing effect, anti-adhesion, complete absorbability, good mechanics performance, low infectiosity and miscible with other pharmacologically medicines.
