The wide application of PLA wire in 3D printer in medical field

[Hermione]

With the continuous progress of science and technology, 3D printing technology is more and more widely used in the medical field. Among them, polylactic acid (PLA) wire, as a biodegradable material, plays an important role in the medical field with its unique properties. This paper will discuss the application of PLA wire in 3D printers in the medical field.

First, PLA wire has significant advantages in 3D printing medical implants. PLA filament has good biocompatibility and can be gradually degraded and absorbed by the human body, so it is widely used in the manufacture of medical implants, such as periosteum and internal inserts. For example, the anchors for the tissue-guided regeneration GTR membrane and bone-guided regeneration GBR membrane produced by Geistlich Orthopedics of Switzerland are made of PLA as raw material. These implants degrade in the body on their own, avoiding the pain of a second surgical removal and reducing the risk to patients.

Secondly, PLA wire also shows great potential in 3D printing medical devices and equipment. Through 3D printing technology, a variety of personalized medical instruments and equipment can be manufactured, such as surgical tools, tractors and so on. These devices can be customized according to the specific situation of the patient, improving the efficiency of surgery and treatment results. For example, the West China Hospital successfully implanted a 3D-printed biological artificial knee joint for patients, which is closely contacted through the prosthesis - bone interface, prompting bone tissue to grow into the prosthesis, and improving the strength of the prosthesis and pulp cavity.

In addition, PLA wire has also made breakthroughs in 3D printing tissue engineering and bioprinting. 3D printing technology can print human tissues, such as skin, blood vessels, etc., and even try to print complete organs, such as hearts. Tel Aviv University in Israel has successfully printed a miniature human heart, which opens up new possibilities for future organ transplants. Artificial tissues and organs manufactured by 3D printing technology can be used for drug screening, disease model research, etc., which has important scientific value and clinical significance.

Finally, PLA wire is also important in 3D printing surgical models and planning. Doctors can make a model of the diseased part through 3D printing technology for surgical planning and simulation, improving the success rate and safety of surgery. For example, in complex fracture cases, doctors can create fracture models through 3D printing technology to help them better understand the extent and location of bone damage and develop more precise treatment plans.

To sum up, PLA wires in 3D printers are widely and deeply used in the medical field, from medical implants to medical devices, to tissue engineering and surgical planning, PLA wires play an important role. With the continuous progress of science and technology, it is believed that the application of PLA wire in the medical field will be more extensive and make greater contributions to the cause of human health.
