Application of 3D printing in prosthetics

1.As 3D printing output materials become more and more diverse, and the applications in medical treatment are increasing day by day, the research team of Virginia Tech recently developed a 3D printed prosthetic leg device with electronic sensors to evaluate the limbs and devices. The pressure distribution makes it more comfortable for the patient to wear.

It is understood that Professor Blake Johnson of the Virginia Institute of Technology used the data collected by the sensors of the prosthesis to improve the device to ensure that the comfort and functionality of the prosthesis can be improved. This research is the function of customized wearable 3D printing devices. Take a big step.

Since customized electronic prostheses are expensive and the comfort may not meet personal standards, the laboratory aims to reduce production costs. The current 3D printed prostheses lack high-end electronic systems, and it is difficult to evaluate whether the user can wear them correctly. For example, when the limb is relaxed or bent, the device will put pressure on different areas of the prosthetic limb.

The report pointed out that the new 3D printing technology integrates materials into the prosthetic fitting area instead of manual adjustment after printing. This can also create different angle positions for different wearer skin characteristics. Compared with traditional methods, new 3D printing technology materials Can be deposited on curved surfaces and objects.

According to the test subjects, although the new prosthesis has high fixation, it also has the characteristics of softness, and the hands can be adjusted to different postures. In addition, 3D printing is relatively easy to operate and inexpensive, gradually replacing traditional prostheses as an indispensable medical application technology.

3D printing is becoming increasingly large in the medical industry market. In addition to achieving the aesthetic effect in the design, it also improves the comfort level. Emerging technologies are positively helping patients on the road to recovery.
