Embodiment 1

[0037] A 3D printing composite material with CT imaging effects, the composite material is composed of the following components in mass percentage:

[0038] Washable photosensitive resin 45wt%;

[0039] Polyacrylic acid 5wt%;

[0040] Nanoscale hydroxyapatite 45wt%;

[0041] Titanium dioxide 5wt%.

[0042] Put the above-mentioned 3D printing composite material with CT imaging effect into the planetary ball mill for ball milling to obtain the ball-milled slurry, set the speed of 300rmp ball milling time for 2h, first rotate forward for 30min and then reverse for 30min for 2 cycles. The slurry of No. 1 3D printing composite material was obtained by this preparation method.

Embodiment 2

[0044] A 3D printing composite material with CT imaging effects, the composite material is composed of the following components in mass percentage:

[0045] Washing photosensitive resin 50wt%;

[0046] Polyacrylic acid 5wt%;

[0047] Nanoscale hydroxyapatite 40wt%;

[0048] Titanium dioxide 5wt%.

[0049] According to the composition of the above components, according to the method for preparing a 3D printing composite material with CT imaging effect in Example 1, the slurry of No. 2 3D printing composite material was prepared.

Embodiment 3

[0051] A 3D printing composite material with CT imaging effects, the composite material is composed of the following components in mass percentage:

[0052] Washing photosensitive resin 55wt%;

[0053] Polyacrylic acid 5wt%;

[0054] Nanoscale hydroxyapatite 35wt%;

[0055] Titanium dioxide 5wt%.

[0056] According to the composition of the above components, according to the method for preparing a 3D printing composite material with CT imaging effects in Example 1, the slurry of No. 3 3D printing composite material was prepared.

Abstract

The invention discloses a 3D printing composite material with a CT imaging effect and a preparation method and application thereof. The 3D printing composite material is prepared from the following components in percentage by mass: 40 to 70 weight percent of photosensitive resin, 5 weight percent of dispersing agent, 20 to 50 weight percent of hydroxyapatite and 5 weight percent of titanium dioxide. By adjusting the printing parameters of the photocuring 3D printer and configuring the printing slurry with the CT imaging effect, a skeleton model and a preoperative guide plate with the CT imaging effect can be printed, so that a doctor can perform preoperative drilling of an orthopedic operation under a CT image, and the success rate of the operation is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and relates to a 3D printing composite material with CT imaging effects, a preparation method and a model making method thereof. Background technique [0002] In recent years, 3D printing technology has developed rapidly, and it is emerging in the production of orthopedic preoperative guide plates or preoperative models. People can establish a 3D model of the patient's damaged bone through CT slice technology, and then use 3D printing technology to make the patient's damaged bone After printing out the model at the site, the doctor can design a surgical plan through the model, and conduct surgical rehearsals under the guidance of CT images, so that the implant can be accurately implanted in the patient, and the operation time, operation cost, and operation risk can be reduced. In this context, 3D printing materials with CT imaging effects are extremely important. [0003] At present, n...
