Parametric Design and 3D Printing Optimize Orthopedic Footwear

Additive manufacturing finds its place in a multitude of applications, both in the world of footwear and in the medical field. In this context, orthopedic shoes are usually associated with unattractive designs, which has led many patients to ignore medical recommendations for their use. However, thanks to advances in new technologies, particularly in parametric design and 3D printing, this perception is beginning to change, and orthopedic shoes can now be both functional and aesthetically pleasing.

One of the main drivers of this innovation is Daniel Petcu, a footwear engineer, who has developed an innovative design method called Pedorthic Information Modeling (PIM). The system uses parametric design principles and Rhino 3D modeling software to create customized orthopedic shoes, tailored to the specific needs of each user. Thus, Petcu’s approach is based on the use of digital models to manufacture customized footwear, which offers advantages in terms of comfort, functionality and, above all, aesthetics.

3D Printing to Create Orthopedic Footwear

The process begins with the creation of a digital model of the shoe, which is adjusted according to the anatomy of the user’s foot, as well as the required structure and stiffness. Thanks to a specific code, the design can be adapted to different podiatric pathologies, such as diabetic foot or fallen arch syndrome in children. An important aspect of this design is the “stiffness gradient,” which allows the flexibility of the shoe to be modified throughout the product, according to the patient’s needs. The use of 3D printing played an essential role in the manufacture of customized orthopedic footwear.
