Problems solved by technology

Projection-type light-curing 3D printing devices can achieve high-precision printing of micron-scale complex shapes, but conventional light-curing 3D printing equipment will damage the cured part of the hydrogel material during the peeling process, resulting in printing failure
There are many problems in the existing light-curing 3D printing equipment, the main problem is that the printing effect on soft hydrogel biomaterials is poor, the success rate is low, the range of printable hydrogel biomaterials is small, and the applicability is not wide

Abstract

The invention discloses a projection type photocuring 3D printing device. The projection type photocuring 3D printing device comprises a rack and further comprises a printing forming platform assembly, a trough assembly, a light source generator and a controller which are fixed in the rack. The trough assembly comprises a trough, a trough platform used for fixing and supporting the trough, and a drive mechanism I capable of driving the trough platform to conduct peeling overturning and return overturning. One side of the trough platform is hinged to the rack, and the other side of the trough platform is in shaft connection to the output end of the drive mechanism I. Under driving of the drive mechanism I, the trough platform conducts peeling overturning with the low speed and conducts return overturning with the high speed. The projection type photocuring 3D printing device meets the requirement for wide printing material coverage while the printing precision is ensured, and the forming performance and biology applicability of projection type photocuring 3D printing are improved.

Description

technical field [0001] The present invention relates to the technical field of photo-curing 3D printing, in particular to a projection-type photo-curing 3D printing device. Background technique [0002] Photocuring 3D printing technology is a 3D printing technology with the highest processing precision at present. Its basic principle is that by using photosensitive resin as raw material, the computer controls the printing light source to irradiate layer by layer according to the cross-sectional graphics of the printed model, and the photosensitive resin exposed to light will undergo photocuring. In this way, a layer of cured pattern is formed, and the forming platform is raised to the height of one layer to print the next layer of light-cured printing. The new cured layer is firmly bonded to the previous layer of cured layer, and the printing of the overall model is completed in a cycle. [0003] Common light-curing 3D printers generally include a platform lifting mechanism,...
