Abstract

The patent of the present invention relates to the technical field of near-field melt electrospinning direct writing, and in particular relates to an unsupported melt electrospinning direct writing device with a tiny three-dimensional structure. The setting of the platform and the Z-axis rotary insulating platform enables the part receiving plate to move horizontally in the X and Y axes, and the rotation of the X and Z axes has 4 degrees of freedom, which can flexibly adjust the posture of the prepared parts, and cooperate with one in the vertical direction. A 3-DOF robotic arm that can be rotated in the direction to adjust the posture of the electrospinning nozzle in the vertical plane. In the process of electrospinning, the present invention can cut the 3D model of the supporting part into smaller parts according to a plane, and each divided part is self-supporting when printed in the normal direction of the standard plane that divides it. Subsequent processing is carried out in sequence, and finally complete parts are printed through continuous unsupported electrospinning direct writing with the previous segment as the base, without adding additional supports, which improves production efficiency.

Description

technical field [0001] The patent of the present invention relates to the technical field of near-field melting electrospinning direct writing, in particular to an unsupported melting electrospinning direct writing device with a tiny three-dimensional structure. Background technique [0002] Electrospinning is a new type of micro-nano manufacturing technology. At present, electrospinning is divided into two types: solution electrospinning and melt electrospinning. Because melt electrospinning was born later, the equipment is more complicated than solution electrospinning, and it requires There are more parameters to control than solution electrospinning, resulting in relatively few people studying and paying attention to this method, but melt electrospinning does not require solvents, which is environmentally friendly, extremely low cost, high efficiency, and strong compared with solution electrospinning. Therefore, melt electrospinning has great development potential in the...
