In this article, 3D‐printed anthropomorphic hands for prosthetic or robotic applications are reviewed as 3D printing has transformed manufacturing by enabling the creation of intricate structures layer by layer, offering design freedom and efficiency. This review categorizes 3D‐printed anthropomorphic hands based on actuation, transmission, joint, and functional features like sensing and grasp patterns. It also assesses the level of anthropomorphism and validation methods by presenting criteria in prosthetic and robotic applications. Then, the article discusses 3D printing technologies in their usage and types, highlighting the advantages of multi‐material capabilities and integration of different hand components. Future directions on structural components, anthropomorphism, validation, and use of 3D printing are discussed, focusing on trends that only 3D printing technology can achieve in anthropomorphic hand development.

“…6 Lost limbs can be rehabilitated with articulated prostheses, facilitating the patient's function. [6][7][8] However, conventional robotics, with rigid and heavy materials, such as metals, loses in the esthetic aspect and is a disadvantage in the case of finger prostheses. Lighter and more flexible prostheses are being studied to combine articulated mechanics and esthetics.…”

“…Lighter and more flexible prostheses are being studied to combine articulated mechanics and esthetics. Using 3D printing, Mutilu et al 6 studied the manufacture of a finger prosthesis with mechanics made of thin sheets of polyvinyl chloride—a lighter and rigid material—superimposed on each other with a design that guaranteed the joint without the use of wheels and coated with a more flexible material, such as silicone. The results were promising in the apprehension of lighter objects.…”

“…Prostheses with the ability to generate sensory feedback to the patient are being developed, an interesting feature for larger amputated regions, such as the hands. [5][6][7][8] These robotic prostheses can facilitate the apprehension of objects because they can be articulated, unlike conventional prostheses that are more rigid. However, this is not the reality of many centers around the world, and the conventional technique presents excellent clinical results.…”

Objective:This study reports a clinical case of rehabilitation of a patient who had her left little finger amputated at the mesial phalanx because of a gunshot wound. The finger prosthesis was custom- made using a silicone.Case description:This study presents a clinical case of a female patient who had her left little finger amputated at the mesial phalanx because of a gunshot wound in 2016. The patient was attended at a reference center in maxillofacial rehabilitation in the city of Brasilia, Distrito Federal, Brazil, for the manufacture of a finger prosthesis. After molding, a finger waxing was obtained using the right little finger as a template. The waxing was later adjusted on the plaster model of the affected stump. The prosthesis was manufactured with silicone and intrinsically stained with a makeup powder. A water-based adhesive and a ring were used to generate a slight compression so that the prosthesis was retained on the stump.Outcomes:The rehabilitation showed satisfactory levels of stability, retention, and aesthetics, and it was usable and clinically acceptable, as observed in a follow-up appointment in February 2020.Conclusions:The complete or partial reestablishment of functions performed by important structures, such as the fingers, is essential to increase the quality of life of individuals, improving their performance of daily activities. In addition, reporting on this public health problem allows scientific advancement in the area.

“…Therefore, we planned to use the latest technology in the implementation field by utilizing 3D printing as a manufacturing method. With the help of 3D printing, we could realize an idea, innovation, concept, invention, or anything digitally drawn in a relatively short time [32], turning it from an essential thought to an actual part. Geometry that was traditionally challenging to manufacture, such as unrealistic overhangs, is now considerably troublefree and effortless.…”

This work described a concept and design of an anthropomorphic robot hand for the T-FLoW 3.0 humanoid robot, which featured a mechanism based on a lever as its finger movement. This work aimed to provide an affordable, modular, lightweight, human-like robot hand with a mechanism that minimizes mechanical slippage. The proposed mechanism works based on the push/pull of a lever attached to the finger to generate its finger flexion/extension movement. The finger’s lever is pushed/pulled through a servo horn and a rigid bar by the affordable TowerPro MG90S micro-servo. Our hand is developed only as necessary to become close to human hands by only applying five fingers and six joints, where each joint has its actuator. The combination of 3D printing technology with PLA filament accelerates and streamlines the manufacturing process, provides a realistic appearance, and achieves a lightweight, affordable, and easy maintenance product. Structural analysis simulations show that our finger design constructed with PLA material could withstand a load of about 30 N. We verified our finger mechanism by repeatedly flexing and extending the finger 30 times, and the results showed that the finger movements could be performed well. Our hand offered excellent handling for the mechanical issues brought on by finger movements, one of the issues that robot hand researchers have encountered. Our work could provide significant benefits to the T-FLoW 3.0 developers in enhancing the ability of humanoid robots involving hands, such as grasping and manipulating objects.
