Application of FDM technology to traditional orthopedics

An important example is the one of 3D printed orthopedic braces in the correction of vertebral dysmorphism produced with FDM technology. The creation of a printed corset provides an innovative process compared to the traditional manufacturing realized with plaster cast. It follows three steps: a quick and easy 3D scanning, a 3D modeling phase with very large possibilities of customization and finally the 3D polypropylene’s printing.

In this case study a brace has been realized to resolve a femur’s fracture in a newborn: it is the alternative to an invasive plaster which covers from the belt to the feet. This solution offers a greater mobility, which is essential in the early years of growth.

Another application is when there are external fixators and a cast is not possible: thanks to this support the knee is immobilized and it’s possibile to start to place the foot on the ground.

The 3D printing opens up new scenarios also on hand devices. It is possible to design ad hoc solutions for the individual patient who had interventions on nerves or for cysts removal. With these devices fingers could drive with a gradual use of the force to regain mobility. The components are lightweight, minimally invasive and aesthetically interesting.

In all the situations, in addition to the benefit for the patient, it is always evident the advantage of digital fabrication technology in terms of process: scanning is immediate and minimally invasive, modeling is highly customizable and there are no materials to be disposed of.

3d printed orthopedic braces with Delta WASP 4070 INDUSTRIAL 4.0 reduces costs and returns a robust and reliable finished product, a guarantee given by the characteristics of the machine and by certified materials.
