A new type of short-process melt electrospinning instrument for an intelligent integrated 3D printing platform

Abstract

The invention discloses a novel short-flow melt electrospinning instrument for an intelligent integrated 3D printing platform, including a motor support frame, a motor, an insulation isolation plate, a second insulation isolation accessory, a gear, a FDM printing wire reel, and an electrostatic field box body, the invention uses 3D printing based on the principle of fusion deposition, the short-flow hot-melt extrusion head system is simple in construction and operation, low in cost, safe in system operation, and simple in post-processing. By applying high voltage, the obtained fibers have micro Compared with the existing electrospinning, the raw material of the present invention is a general-purpose 3D printing consumable. By adopting 3D printing, it is intelligently integrated with the self-assembled electrostatic field, and the shape of the formed fiber is controllable, and the air circulation is carried out. At the same time, the exhaust fan and the intake fan work at the same time to realize the heat dissipation of the box. After the air entering is settled and dried, it will not affect the material processing in the box, which can better ensure the quality of the material.

[0002] Additive manufacturing technology, also known as 3D printing, is one of the main methods of material processing and molding. It is a fast and short process for realizing intelligence through computer-aided design, based on digital model files, and forming products according to the principle of layer-by-layer accumulation. Forming technology, but under the 3D printing technology, it is impossible to realize the micro-nano level control printing problem of the polymer melt. Therefore, by placing the melt of the 3D printing consumables under the condition of a high-voltage assembly electrostatic field, the short-process micro-nano level melt electrospinning can be realized. Silk, to avoid the disadvantages of polymer pellets due to different particle sizes, uneven feeding and long-term heating and aging of the spinning melt, resulting in differences in the diameter of the spinning fiber and mechanical properties. When printing, there is no air intake tube, only the gap To achieve air circulation, dust and moisture enter the box, and the heat dissipation effect is poor, which will affect the printing effect
