Medical 3D printing SLA customized rapid prototyping

In the future, surgeons may be able to use printing equipment to print bones of various sizes on site during surgery for clinical use. This magical 3D printer has been built, and printing materials used to replace real human bones are being tested intensively. In laboratory tests, the bone-replacement printing material has been shown to support the growth of human bone cells within it, and its effectiveness has also been demonstrated in mice and rabbits. In the next few years, better-quality printed bone substitutes may help surgeons repair bone damage, be used in dental offices, and even help osteoporosis patients regain their health.
3 Printing technology has emerged rapidly and has become a hot new industry. The types of three-dimensional products it can print are rapidly increasing. To print the bone material, Boss and her colleagues used a commercially available printer for testing. This 3-printer was originally designed to print metal parts. It sprays plastic particles layer by layer on a powder base and forms them layer by layer. Each layer is only half the width of a human hair.
The main material component of this bone scaffold is calcium phosphate, with additional silicon and zinc added to enhance its strength. When it is implanted into the human body, it can temporarily support the bones, and in the process help normal bone cells grow and develop and repair previous damage, and then the material can naturally dissolve in the human body.
It took scientists years to find the right formula for this material, involving many disciplines of chemistry, materials science, biology and process science.
