Resumo(s)
This study demonstrated that, in relation to Additive Manufacturing, Three-Dimensional (3D) Printing is a technology that is increasingly present in everyday life in the manufacturing of parts. In this case, the piece manufactured using 3D printing was a hand orthosis, intended to alleviate the pain of a woman suffering from a medical condition.
This study highlights the growing presence of three-dimensional (3D) printing in everyday life, particularly in the manufacture of customized medical devices. In the field of additive
manufacturing (AM), Material Extrusion (MEX), ISO/ASTM 52900:2023, (fused deposition modeling (FDM)) has become a widely used technique due to its affordability, accessibility, and
ability to create personalized solutions. In this case, a 3D-printed hand orthosis was designed to assist a woman suffering from tendinitis in her thumb. The orthosis was designed to reduce pain and provide support to improve her daily functionality. Material Extrusion (MEX), FDM technology was used to build the device layer by layer, resulting in a lightweight yet durable structure tailored to the patient's needs. One of the key benefits of 3D printing in orthotic design is the ability to create customized, patient-specific solutions at a lower cost than traditional manufacturing. In addition, rapid prototyping allows for quick modifications based on patient feedback, improving comfort and effectiveness. Traditional orthotic manufacturing methods require expensive molds and labor-intensive processes, whereas 3D printing streamlines production, allowing for efficient, scalable, and precise results.
Another advantage of this technique is the wide range of materials available for use in 3D printing. From biodegradable polymers to highly durable composites, the choice of material can be tailored to the specific needs of each patient, ensuring not only comfort but also long-term durability. For example, in this case, PLA was used, a material known for its low cost, ease of printing, and environmental sustainability. This study reinforces the potential of 3D printing in medical applications and demonstrates how FDM-printed orthotics can help alleviate pain and improve quality of life for people with musculoskeletal conditions. As the technology continues to evolve, personalized healthcare solutions will become more accessible and efficient. The implications of this advancement extend beyond orthotic production, opening possibilities for broader applications in medical fields, including prosthetics, implants, and even tissue engineering.
