Focusing on the application needs of segmented fields, Xianlin 3D has assisted Wuhan Biying Biotechnology Co., Ltd. in creating the world's first orthopedic external fixation 3D real-time printing system that meets clinical operating standards with excellent high-precision 3D scanning technology.

By combining the advantages of our products, we aim to better serve more hospitals, institutions or enterprises that specialize in customizing rehabilitation aids such as external fixation braces and orthotics for orthopedic patients, and bring new assistance to public health.

As is well known, traditional orthopedic external fixation techniques use plaster to assist in reduction, but the efficiency of plaster application is too low, inaccurate, and patients are not easy to remove and wash. Therefore, the "3D printing external fixation frame" technology, which can easily help patients achieve precise reduction, reduce patient pain, and promote fracture healing, has been increasingly applied in recent years.

However, the manufacturing process of general 3D printing external fixed supports has obvious drawbacks, such as:

The patient needs to achieve fixation within 2 hours after injury, otherwise it can easily lead to secondary injury, which is difficult for ordinary 3D printers to meet. The combined design and printing time takes more than 5-7 hours.

The process of mold taking, design, and production is cumbersome, and most doctors do not have relevant professional software and machine operation knowledge, resulting in high learning barriers and time costs.

To this end, Biying Biotechnology has developed a real-time 3D printing external fixation system, an automated system that can obtain body surface data through handheld scanning devices, based on digital model files, and use composite starch based powder materials to instantly construct external fixation supports through layer by layer printing.

For example, the production of external fixation supports for the wrist joint:

Scanning the wrist with a handheld 3D scanner, the wrist model can be automatically drawn on the computer within 20 seconds;

The model data is intelligently processed, designed and sliced by the system, and the external fixed support of the wrist can be printed using a 3D printer in about 10 minutes;

The efficiency is more than 20 times that of traditional 3D printing external fixture technology.

From 7 hours to 20 minutes, the real-time 3D printing external fixation system doubles the production speed of orthopedic 3D printing external fixation frames.

In the process of system development, in order to improve the workflow and improve the overall production efficiency and quality, the research and development team of Biying Biotechnology has undergone multiple comparative tests and finally chose to cooperate with Xianlin 3D. The EinScan Pro 2X series multifunctional handheld 3D scanner and EinScan H dual light source color handheld 3D scanner have been included in the "data acquisition" process of the real-time 3D printing external fixation system.

It can intelligently fill in light, improve scanning comfort, and do no harm to the human body and eyes, avoiding secondary harm to the patient's injuries.

The advantages of real-time 3D external fixed printing system

It takes 2-3 minutes to quickly complete digital modeling and obtain accurate data. Subsequently, through intelligent system design, it perfectly fits the affected area and achieves the best recovery posture;

High degree of automation processing, instant printing and molding, patient disposal can be completed in 20 to 30 minutes, meeting clinical standard requirements;

The support adopts a porous design, with a lightweight and breathable texture, which can effectively avoid patient wounds, not affect dressing changes and wound treatment, and improve the healing rate;

There are few clinical contraindications, precise reduction, and reliable support fixation, which can promote fracture healing, reduce postoperative recovery time, and alleviate patient pain;

Compared to traditional petroleum based materials, all starch materials are more eco-friendly and cost-effective, with greatly improved aesthetics, hardness, and texture.

Through this collaboration that combines technological characteristics, Xianlin 3D and Biying Biotechnology will work together to promote the application of 3D scanning and 3D printing technology in fields such as orthopedic external fixation and orthopedic appliances, helping the medical rehabilitation accessory industry with a market of hundreds of billions to develop towards digitization, personalization, precision, and intelligence.

In the future, Xianlin 3D will continue to delve into more segmented scenarios in the medical industry, providing high-quality and efficient 3D digital products and services to global customers, and deepening the application of high-precision 3D digital technology in the field of precision medicine. With the power of technology, we will help create a healthier quality life!
