3D PROSTHETIC SOCKET

The uncomfortable receiving cavity is a common problem encountered by prosthetic users. This is because the traditional receiving cavity is a single piece of plastic molded according to the user's physical condition at the time. This creates a big problem, because the stress caused by exercise is constantly changing throughout the day.

ProsFit provides a software solution called PandoFit that enables prosthetics doctors to perform 3D scans and create custom limb receiving cavities on the screen. After the design is completed, ProsFit uses 3D printing technology to manufacture the receiving cavity.

The main components of the leg prosthesis are divided into two parts: custom-made receptacles for each residual limb and other parts-such as prosthetic feet, knees and connecting elements. These elements are products produced using standardized traditional processes.

With traditional manufacturing processes, it may take several weeks to install the prosthesis. During this period, most patients are forced to use crutches or confined to a wheelchair, limiting their mobility, and the manufacturing process is expensive and time-consuming.

Through the process of digitally designing, assembling and manufacturing the prosthesis receptacle, ProsFit reduces the time required to manufacture and deliver the receptacle from several weeks to several days, with much fewer steps, which helps reduce costs and improve patient comfort .

Using HP's Multi Jet Fusion technology, technicians can choose the direction of the parts on the 3D printer, thereby providing an optimized combination of quality, strength, flexibility and economy.

In general, the combination of 3D scanning, software and 3D printing enables 3D printing to change the current production status of prosthetic receptacles and provide a fully digital solution for the prosthetic industry.

In China, the State Council pointed out in the "Several Opinions on Accelerating the Development of Rehabilitation Assistive Devices Industry" that my country is the country with the largest demand for rehabilitation assistive devices and the largest market potential in the world. The additive manufacturing (3D printing technology) proposed in the "Opinions" has played an important role in promoting the design innovation of rehabilitation aids and improving the level of customization.
