presented by Engineer Aya Talib Hassan The field of prosthetics has witnessed remarkable development in recent years, with one of the most significant advancements being the adoption of 3D scanner technology in the design and fabrication of prosthetic limbs. This modern technology has contributed to improving measurement accuracy, reducing production time, and enhancing comfort and performance for users. 3D scanner technology works by scanning the residual limb using highly accurate sensors that create a digital three-dimensional model of the targeted area. Through this model, the engineer or specialist can precisely analyze the shape and dimensions of the limb, then design the socket and other components using specialized engineering software. One of the key advantages of using 3D scanners in prosthetics is the reduction of human errors that may occur with traditional casting methods or manual measurements. In addition, it saves time and effort while allowing digital storage of patient data for future adjustments or replacement of the prosthetic limb when needed. This technology also helps provide prosthetic limbs that are more comfortable and better fitted for users, as the design closely matches the actual shape of the residual limb. This reduces pressure points and friction, while increasing the patient’s ability to move naturally in daily life. Furthermore, 3D scanning can be integrated with 3D printing technology to manufacture certain prosthetic components quickly and at a lower cost. This opens up wide opportunities for delivering advanced rehabilitation solutions in developing countries and modern medical centers. Despite these advantages, some challenges still remain, such as the high cost of equipment and software, as well as the need for trained personnel capable of operating these technologies. However, continuous technological progress is expected to make them more widely available in the near future. In conclusion, prosthetic limbs using 3D scanner technology represent a qualitative leap in the field of prosthetics and orthotics, providing greater accuracy, speed, and user comfort, while contributing to improved quality of life and better social reintegration for individuals.
