Antarctic bear guide: autologous bone is known as the "gold standard" of bone defect repair, but autologous bone due to the scarcity of quantity, multiple surgeries, shape is difficult to control and other factors, which limits its application in bone defect repair, and allogeneic bone is facing a huge risk of immune rejection, artificial bone has undoubtedly become an ideal alternative, with the in-depth application of 3D printing technology in the medical field, the production method of artificial bone is also undergoing a profound change.
△ QIYU Technology light-curing 3D printing equipment printing hydroxyapatite process and finished product display
With a comprehensive layout of light-curing ceramic 3D printing equipment, materials and processes, QIYU Technology is committed to providing a complete solution for bone repair. The light-curing 3D printing hydroxyapatite (HAP) and tricalcium phosphate (TCP) products developed by the company have good biocompatibility, mechanical strength and porosity, and can also provide customized and accurate overall solutions for scientific research institutions or enterprise R&D personnel.
Advanced Materials: The perfect balance of biocompatibility and mechanical properties
Hydroxyapatite (HAP) and tricalcium phosphate (TCP) are two of the most commonly used bioceramics in bone repair materials. The 3D printing materials developed by QIYU Technology not only maintain excellent biocompatibility, but also have excellent mechanical strength. With the support of 3D printing technology, the design structure of the sample can be accurately controlled, flexibly adjusted according to the needs and quickly verified.

Ultra-fast light-curing DLP ceramic 3D printing equipment: both speed and stability
The light-curing DLP ceramic 3D printing equipment independently developed by QIYU Technology has industry-leading printing speed and printing stability, which meets the design needs of high complexity in the production of artificial bones, and at the same time, meets the pursuit of production efficiency of enterprises.
(1) Ultra-fast: the mass production efficiency can be as high as about 350cm3/h (take ADT-3D-Printer-Pro-144-37.5 as an example, solid printing. Larger devices are more efficient)
(2) High stability: the printing pass rate is 99% (taking ADT-3D-Printer-Pro-144-37.5 as an example, the printing φ = 9.3*12mm cylinder, the layout spacing is 0.8mm, 12 per plate, 560 samples for 5 editions, 555 qualified samples, and the pass rate is 99%)
