【3D Printing News】New Applications for Medical Aids: Flexible Materials Tested for Ultra-Flexibility!
In recent years, the application range of 3D printing has not only become more extensive, but thanks to many leading figures in industry and commerce who have taken the initiative to try it, 3D printing technology has gradually entered the medical industry, generating more value. In addition to the pre-operative communication models we previously shared (further reading: Humanizing Clinical Teaching, A New Catalyst for Doctor-Patient Relationships!), an increasing number of wearable assistive devices are now being produced using 3D printing. This time, 3DMart will demonstrate the effects of 3D printing wrist braces using both rigid and new flexible materials! First, let's look at the elasticity of the soft material:
We found two styles of braces and wrist supports on a 3D open-source model site, suitable for printing with soft and rigid materials respectively. In Cura's preview, you can see that the soft material only needs to be printed flat. (Further reading: Free Resources Unveiled! Top 5 3D Model Libraries Here!)
We used the latest Ultimaker S5 and S3 to print simultaneously, which saved time. The latest Ultimaker S3 on the right can be considered a miniature version of the S5. In addition to being equipped with glass doors and a full touchscreen, it also features upgraded feed gears and filament run-out detection, which were not available in the older Ultimaker 3. This allows it to print abrasive materials and composites. (Further reading: More Powerful, Smaller Footprint: Ultimaker S3 New Release!)
Since the wrist brace design naturally features many ventilation holes, we specifically tested the effect of third-party TPU on the elastic wrist brace. After completion with the Ultimaker S5 3D printer, no further trimming was required. This TPU produced virtually no stringing, and the finished product's appearance was satisfying. Now, let's see how it performs in use!
The rigid wrist brace has an opening on the left side for slight expansion during putting on and taking off. The brace is paired with a velcro strap, with three strap holes on each side, large enough for the thumb to pass through directly.
Testing the elasticity of TPU flexible material showed that the wrist brace can bend to wrap and secure the palm, effectively generating sufficient resistance to prevent further injury to the patient during daily activities.
However, the colleague demonstrating has large hands, so it feels like when 3D printing medical aids, designing the bottom surface that contacts the platform with a curved edge would be more comfortable. Nevertheless, the strength of the 3D printed product can effectively restrict the movement of the affected area and be customized for different cases, improving medical quality and speed. Perhaps in the future, even a commemorative signature can be engraved!
Do you have similar needs? Feel free to contact us and schedule an appointment to visit 3DMart to see these exciting application cases. We can provide relevant consultations and help you fully understand how to integrate 3D printers into your manufacturing process to achieve maximum benefits. This third-party TPU, which performed well in this test, will also be available soon! Please stay tuned to 3DMart's FB page or latest news!
