Abstract

The invention relates to the technical field of near-field fusion electrostatic spinning direct writing, in particular to a support-free fusion electrostatic spinning direct writing device with a tiny three-dimensional structure. By arrangement of a Y-axis horizontal motion platform, an X-axis horizontal motion platform, an X-axis rotating platform and a Z-axis rotating insulating platform, a part receiving plate can finally horizontally move in the X axis and the Y axis. Rotation of the X axis and Z axis has 4 degrees of freedom, the posture of a prepared part can be flexibly adjusted, and a three-degree-of-freedom mechanical arm capable of rotating in the vertical direction is matched to adjust the posture of an electrostatic spinning nozzle in the vertical plane. In the electrostatic spinning process, a 3D model supporting the part can be cut into smaller portions according to a plane, each segmented portion is self-supported during printing in the normal direction of a standard plane for segmenting the part, and subsequent processing is performed in sequence during segmentation; and finally, through continuous support-free electrostatic spinning direct writing with the previous segmented portion as a substrate, a complete part is printed, additional supports do not need to be added, and the production efficiency is improved.

Description

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