Both Adam and I share a common background as orthotists and prosthetists, which gives us a unique perspective and deep understanding of the challenges faced by patients and practitioners in the orthopedic field. Our professional experience highlighted the limitations of conventional manufacturing techniques in creating truly bespoke and efficient orthopedic aids. This insight fueled our ambition to establish OrthoVoxel with a clear objective: to thoroughly explore and implement the transformative applications of additive manufacturing within the specialized domain of orthopedic prosthetics and orthotics. Our goal from the outset was to harness this advanced technology to overcome existing barriers and deliver superior patient outcomes.

The Driving Force: Why 3D Printing for Orthopedics?

As dedicated enthusiasts of emerging technologies, Adam and I were immediately captivated by the immense potential of 3D printing. We recognized its inherent ability to push the boundaries of creativity, precision, and innovation, far beyond what traditional manufacturing methods could offer. Traditional orthopedic device production often involves labor-intensive processes like plaster casting, manual molding, and iterative adjustments, which can be time-consuming, expensive, and sometimes uncomfortable for patients. These methods also limit design complexity and material customization, often resulting in “one-size-fits-most” solutions that compromise on fit and functionality.

We quickly realized that integrating advanced digital modeling tools with additive manufacturing technologies would allow us to fundamentally improve our entire production process. This digital workflow offers several critical advantages. Firstly, it ensures consistent quality across every device produced, minimizing human error and guaranteeing reliable performance. Secondly, and perhaps most importantly for our field, it enables unprecedented levels of customization. We can now create devices that are perfectly tailored to the unique anatomical needs and functional requirements of each individual client. This precision results in orthoses and prosthetics that are not only more comfortable but also significantly more effective in supporting mobility, promoting rehabilitation, and enhancing the overall quality of life for our patients. The ability to rapidly iterate designs, integrate complex geometries, and optimize material usage further solidified our decision to fully embrace 3D printing as the cornerstone of OrthoVoxel’s operations.

Diverse Range of Orthopedic Devices Offered by OrthoVoxel

At OrthoVoxel, our expertise extends to designing and manufacturing a comprehensive array of orthopedic devices, tailored to meet diverse patient needs. Our offerings range from traditional prosthetics and orthotics, which form the core of our practice, to highly specialized products designed for specific conditions. For instance, we meticulously craft spastic hand orthoses, which require intricate designs to provide precise support and improve function for individuals with neurological conditions. We also produce post-traumatic braces, engineered to aid recovery and stability following injuries, ensuring optimal healing and reduced rehabilitation time.

Beyond these more common applications, our capabilities extend to custom large-format manufacturing. A notable example is our production of positioning seat components. These require substantial size and structural integrity, and 3D printing allows us to create bespoke solutions that offer optimal comfort and therapeutic positioning for patients with complex mobility challenges. The inherent flexibility of additive manufacturing empowers us to achieve perfect anatomical fits and integrate complex features, resulting in devices that not only perform exceptionally but also significantly enhance patient comfort and compliance. This broad capability underscores our commitment to addressing a wide spectrum of orthopedic needs with innovative and patient-centric solutions.

Advanced 3D Printing Technologies and Materials at OrthoVoxel

At OrthoVoxel, our commitment to excellence and innovation is reflected in our careful selection and mastery of cutting-edge 3D printing technologies and materials. We primarily utilize a dual-pronged approach, employing two distinct additive manufacturing processes to cater to the specific requirements of our diverse range of orthopedic devices.

For the production of larger components, especially those requiring significant structural integrity and specific mechanical properties, we have developed our own advanced FFF (Fused Filament Fabrication) filament deposition printers. This internal development allows us to precisely control the printing process and optimize it for the unique demands of orthopedic applications. Our FFF printers are capable of handling technical materials such as carbon-filled polypropylene. This material is chosen for its exceptional strength-to-weight ratio, high stiffness, and durability, making it ideal for devices that need to withstand significant loads while remaining lightweight. The ability to print large parts efficiently with such robust materials is a key advantage of our customized FFF setup, allowing us to produce strong, functional, and reliable components.

For devices demanding high-end finishes, intricate geometries, and superior mechanical performance, we turn to powder sintering technologies. Specifically, we employ MJF (Multi Jet Fusion) and SLS (Selective Laser Sintering) processes. These technologies are renowned for their ability to produce parts with excellent surface quality, fine detail resolution, and isotropic mechanical properties. With MJF and SLS, we frequently work with semi-flexible materials like polyurethane. Polyurethane is an excellent choice for orthopedic applications due to its inherent flexibility, high impact resistance, and comfortable feel against the skin. This makes it perfect for components that require a degree of elasticity, shock absorption, or direct contact with sensitive areas of the body, ensuring both patient comfort and long-term durability.

The strategic combination of our custom FFF systems and advanced powder bed fusion printers, coupled with a carefully selected palette of high-performance materials, enables OrthoVoxel to manufacture a wide spectrum of orthopedic devices. Each device is optimized not only for its specific function but also for the ultimate comfort and satisfaction of the patient, truly showcasing the versatility and power of modern additive manufacturing in clinical applications.

The Streamlined Digital Manufacturing Process

Our manufacturing process at OrthoVoxel has undergone a complete evolution, transforming into a fully digital workflow that prioritizes precision, efficiency, and patient comfort from start to finish. This streamlined approach begins with the crucial first step: measurement acquisition. Instead of traditional, often cumbersome, and uncomfortable casting methods, we capture patient anatomy directly using advanced 3D scanners. This technology provides incredibly accurate, detailed digital models of the patient’s limb or body part, ensuring a perfect foundation for design. The scanning process is quick, non-invasive, and far more comfortable for the patient, significantly improving their initial experience.

Once the precise 3D scan data is obtained, our team utilizes a sophisticated combination of modeling software. These powerful digital tools allow us to design the orthopedic devices with unparalleled accuracy, integrating all necessary components seamlessly into a single digital file. This means that features like hinges, straps, padding, and ventilation holes can be designed as part of the overall structure, rather than being added as separate components later. This holistic design approach is crucial for optimizing the device’s functionality, ergonomics, and aesthetics.

The final, and perhaps most innovative, stage of our process involves directly manufacturing the device based on this integrated digital design. By leveraging our advanced 3D printing technologies, we can produce complex orthopedic devices as a single, cohesive unit. This direct printing method eliminates the need for multiple assembly steps, which are common in traditional manufacturing. The benefits are profound: reduced potential points of failure, enhanced structural integrity, and a much faster turnaround time from design to finished product.
