With the continuous progress of science and technology, 3D printing technology is more and more widely used in various fields, especially in the biomedical field. ABS (acrylonitrile-butadiene-styrene copolymer) filament, as a commonly used 3D printing material, is favored for its good mechanical properties, heat resistance and chemical stability. In recent years, the breakthrough process of ABS filament in bioprinting has attracted wide attention. Biopriting is a method of using 3D printing technology to manufacture biological tissues or organs, the core of which is to stack cells, biological materials and growth factors in accordance with specific structures, and finally form tissues or organs with biological functions. The application of ABS filament in bioprinting is mainly reflected in its use as a supporting material. In the bioprinting process, the structure of the tissue or organ often requires some support to maintain its shape and stability. Traditional support materials may cause damage to cells during the removal process, affecting the biological function of the printed tissue. ABS filament, due to its good solubility, can be removed by a simple dissolution process after printing, greatly reducing the risk of cell damage. This feature makes ABS filament stand out in the choice of bioprinting support materials. In addition, the biocompatibility of ABS filament is also one of the important reasons for its wide application in the bioprinting field. ABS filament can be better combined with biomaterials and promote cell adhesion and growth by surface modification treatment. This not only improves the biological function of bioprinted tissue, but also opens up new possibilities for tissue engineering and regenerative medicine. In terms of research, many research teams at home and abroad have carried out relevant research on ABS filament in bioprinting, and made a series of breakthrough progress. For example, a research team used ABS filament as a support material to successfully print a tissue-engineered scaffold with a complex blood vessel structure. This achievement not only shows the great potential of ABS filament in biopraying, but also provides a new idea for the future realization of personalized tissue and organ manufacturing. Although ABS filament has made a certain breakthrough in the field of bioprinting, there are still some challenges. For example, how to further improve the biocompatibility of ABS filament and how to optimize the printing parameters to improve the biological function of printed tissue still need to be further studied and solved. It is believed that with the continuous progress of science and technology, these problems will be gradually solved, and the application prospect of ABS filament in the bioprinting field will be broader. In short, the breakthrough process of ABS filament in bioprinting has brought new hope for tissue engineering and regenerative medicine. In the future, with the continuous progress of technology, the application of ABS filament in the bioprinting field will be more extensive and make greater contributions to the development of human health.

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) filament, as a biodegradable material, plays an important role in the medical field with its unique properties. This paper will discuss the application of PLA filament in 3D printers in the medical field. First, PLA filament 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 filament 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 filament 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 filament 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 filaments 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 filaments play an important role. With the continuous progress of science and technology, it is believed that the application of PLA filament in the medical field will be more extensive and make greater contributions to the cause of human health.
