3D Digital Solutions for Custom Prosthetics and Orthopedic Devices
What Is Medical 3D Printing
3D printing in the medical sector represents one of the most important innovations in modern healthcare. From the production of custom prosthetics to the bioprinting of human tissues, this technology is radically transforming the way doctors and engineers design, test, and develop therapeutic solutions.
Medical 3D printing is an additive manufacturing process that enables the creation of three-dimensional objects from digital models. It is widely used in advanced bioprinting research, customized prosthetics and orthopedic braces, as well as anatomical models for surgical planning and medical training.
Advantages of 3D Printing in Medicine
3D printing provides greater design freedom, enabling the creation of multifunctional and fully customized components without the limitations of traditional manufacturing methods.
This technology offers several advantages, especially when dealing with patient-specific anatomies. Every patient is unique and requires a different design and a tailored medical solution. Thanks to 3D printing processes, it is possible to develop customized devices and treatments for individual cases with a high level of precision, improving comfort, functionality, and clinical outcomes.
3D Printing in Orthopedics and Prosthetics
The production process of a 3D-printed prosthesis or orthotic device is based on an advanced digital workflow:
1. Patient Scanning: Using 3D scanners or medical imaging technologies such as CT scans and MRI, the patient’s exact anatomy is captured with high precision.
2. CAD Modeling: The acquired data is converted into a digital model optimized for functionality, comfort, and anatomical accuracy.
3. Additive Manufacturing: The prosthetic or orthotic device is produced using professional 3D printers and technical, biocompatible materials.
4. Finishing and Customization: The final device is refined and adjusted to ensure ergonomics, safety, durability, and patient comfort.
Medical 3D Printing: Clinical Applications and Case Studies
Thanks to additive manufacturing, it is now possible to create devices perfectly tailored to the patient’s anatomy, improving comfort, functionality, and clinical outcomes.
3D printing in orthopedics is radically transforming the medical sector by introducing new possibilities in the design and production of customized prosthetic and orthotic devices. This technological evolution represents a major step toward a more personalized and digital approach to healthcare.
Orthopedic Anti-Gravity Corset by Ortopedia 3D, in Certified Medical-Grade PP
Ortopedia 3D has developed a range of anti-gravity corsets using a fully digital workflow, the result of years of technological and medical research in the orthopedic sector.
Digitization and Personalization
Thanks to 3D patient scanning, it is possible to quickly obtain a high-resolution digital model in a non-invasive and comfortable way, even for patients with reduced mobility. This enables the production of highly personalized devices tailored to the specific needs of each individual.
Device Features
The corsets are designed to be ergonomic, lightweight, breathable, and easy to wear, improving patient comfort and compliance without compromising respiration. Through 3D modeling algorithms, biomechanical structures and functional textures are integrated to enhance performance, aesthetics, and ventilation.
Materials and 3D Printing
Production is carried out using WASP 4070 FX 3D printing technology with Fortis LL Polypropylene, a medical-certified material suitable for skin contact. It is characterized by high mechanical strength, low weight, and long-term durability.
Clinical Outcomes
The pilot project, conducted on elderly patients with osteoporotic vertebral collapse, showed high tolerance of the corset, improved psychological acceptance, and tangible clinical benefits such as reduced pain, improved posture, increased mobility, and reduced need for daily assistance.
Procosil 3D-Printed Foot Prosthesis Using WASP 4070 FX and Delta WASP 2040 PRO in PLA and TPU Materials
The prosthesis creation process developed by Procosil involves scanning and 3D printing the patient’s residual limb to produce a silicone socket. The process uses AlfaPro material by FiloAlfa, which is suitable for the high temperatures required for silicone curing, ensuring dimensional stability and high precision of the final component.
Production and Advantages
Printing is carried out using WASP 4070 FX technology, applying specific infill and perimeter parameters to prevent deformation. Compared to traditional plaster-based manufacturing, this method significantly reduces production times, as the printed component is immediately ready for use.
Internal Structure Manufacturing
For the silicone glove, an internal core is produced using 3D printing with flexible FilaFlex 95A material by Recreus, chosen to provide comfort and freedom of movement for the patient.
Comfort and Functionality
The internal core, already integrated with a compensatory insole, is printed using Delta WASP 2040 PRO technology, with optimized parameters designed to ensure softness, durability, and proper comfort during use.
Barbieri Spa Modular Postural Support for Children 3D-Printed with WASP 4070 ZX in PETG
The Koala Modular Postural Unit developed by Progettiamo Autonomia is a lightweight, modular medical device designed to support the posture of children aged 4 months to 4 years with hypotonia or flaccidity. It is engineered to accompany the child’s growth in a comfortable, breathable, and functional way, promoting autonomy and interaction with the surrounding environment.
Advantages of 3D Printing
Daily user management is significantly simplified. Pediatric postural systems must allow the child to be transported without being removed from the seating system, making device weight reduction essential. Traditional manufacturing methods do not ensure sufficient lightness or customization, while injection molding involves high costs and limits the ability to produce truly tailored solutions.
High mechanical performance and a wide range of colors help meet both patient and caregiver preferences. FDM 3D printing with materials such as PETG and ABS enables the production of lightweight yet durable components, while also offering extensive color options. This is particularly important in pediatric orthopedics, where aesthetic preferences play a key role for both children and parents.
User-specific custom components and competitive pricing compared to small-to-medium production runs. 3D printing allows the creation of fully customized parts based on individual patient needs, overcoming the limitations of traditional mass production based on standardized components and enabling truly personalized orthopedic solutions..
