“…These techniques have been already applied to the manufacturing of spinal braces [11,12], exoskeleton parts [13,14], and passive orthoses [15][16][17], and the application in the medical and dental industry represents one of largest serving industries in the world [18]. Moreover, RPT offer advantages in the design of custom orthotic devices ( Figure 1): The orthotic and prosthetic devices are highly customizable, as in Zuniga et al [19], it is possible to fit the devices to complex geometrical features, with high accuracy, and these devices are manufactured efficiently in terms of cost, lead-time, and product quality [20]. [21]).…”

In this work, the recent advances for rapid prototyping in the orthoprosthetic industry are presented. Specifically, the manufacturing process of orthoprosthetic aids are analysed, as thier use is widely extended in orthopedic surgery. These devices are devoted to either correct posture or movement (orthosis) or to substitute a body segment (prosthesis) while maintaining functionality. The manufacturing process is traditionally mainly hand-crafted: The subject’s morphology is taken by means of plaster molds, and the manufacture is performed individually, by adjusting the prototype over the subject. This industry has incorporated computer aided design (CAD), computed aided engineering (CAE) and computed aided manufacturing (CAM) tools; however, the true revolution is the result of the application of rapid prototyping technologies (RPT). Techniques such as fused deposition modelling (FDM), selective laser sintering (SLS), laminated object manufacturing (LOM), and 3D printing (3DP) are some examples of the available methodologies in the manufacturing industry that, step by step, are being included in the rehabilitation engineering market—an engineering field with growth and prospects in the coming years. In this work we analyse different methodologies for additive manufacturing along with the principal methods for collecting 3D body shapes and their application in the manufacturing of functional devices for rehabilitation purposes such as splints, ankle-foot orthoses, or arm prostheses.

“…The possibility of using statistical data such as contour plots to predict which geometric and manufacturing variables are necessary for lattice samples to exhibit specific elastic behaviour was demonstrated. Each of the results obtained showed that the studied variables were within the intervals predicted by the contour plots, even for previously considered values of unstudied parameters (de la Rosa et al, 2023). In this sense, designs with adjustable module have become necessary for applications in therapeutic products since the contact tension between body parts and the environment is a critical factor for the development of problems such as ulcers.…”

“…In this sense, conventional manufacturing methods currently do not rival FFF processes because it is possible to generate free-support non-solid internal geometries with the possibility of providing a different elasticity to the same product, as well as obtaining elastic materials from rigid materials and different elasticities from the same elastic material (Herzberger et al, 2019;Rahmatabadi et al, 2023b;Rodríguez-Parada et al, 2021). As a consequence, the versatility and control over the manufacturing process offered by AM, has led to a growing trend in the use of lattice structures, making available a wide range of possibilities in the manufacture of lattice geometries and structures with more complex architectures (Almesmari et al, 2023;Günaydın et al, 2022;Kumar et al, 2020;de la Rosa et al, 2023;Nazir et al, 2023;Niknam and Akbarzadeh, 2020a;Prajapati et al, 2022a;de la Rosa et al, 2021). Several geometric lattice structures have been tested to improve their performance as a function of their mechanical properties (Almesmari et al, 2023;Günaydın et al, 2022;Mahbod and Asgari, 2019;Momeni et al, 2019;Nazir et al, 2023;Niknam and Akbarzadeh, 2020;Pham et al, 2019;Prajapati et al, 2022a;Sha et al, 2018;Wang et al, 2022).…”

“…For this, a gait analysis is carried out to determine the support points of the foot (García-Dominguez et al , 2020a, 2020b). Other examples focused in the development of orthoses and products for the localized treatment of different parts of the body have been developed (Barrios-Muriel et al , 2020; de Carvalho Filho et al , 2020; Haro et al , 2018; Orozco et al , 2019; Santos et al , 2017; Yan et al , 2019). In general, the method of 3D scanning of the user’s body parts is observed to build a product from the scanned surfaces using CAD and topological optimization.…”

Purpose This papers aims to study lattice structures in terms of geometric variables, manufacturing variables and material-based variants and their correlation with compressive behaviour for their application in a methodology for the design and development of personalized elastic therapeutic products. Design/methodology/approach Lattice samples were designed and manufactured using extrusion-based additive manufacturing technologies. Mechanical tests were carried out on lattice samples for elasticity characterization purposes. The relationships between sample stiffness and key geometric and manufacturing variables were subsequently used in the case study on the design of a pressure cushion model for validation purposes. Differentiated areas were established according to patient’s pressure map to subsequently make a correlation between the patient’s pressure needs and lattice samples stiffness. Findings A substantial and wide variation in lattice compressive behaviour was found depending on the key study variables. The proposed methodology made it possible to efficiently identify and adjust the pressure of the different areas of the product to adapt them to the elastic needs of the patient. In this sense, the characterization lattice samples turned out to provide an effective and flexible response to the pressure requirements. Originality/value This study provides a generalized foundation of lattice structural design and adjustable stiffness in application of pressure cushions, which can be equally applied to other designs with similar purposes. The relevance and contribution of this work lie in the proposed methodology for the design of personalized therapeutic products based on the use of individual lattice structures that function as independent customizable cells.

Cerebral palsy (CP) is a physical disability in childhood with impaired development of movement and posture due to disorders of the fetal or infant's brain. The measurement results of the spastic HCP children at YPAC Surakarta show that 8 attributes have difficulty grasping the precision type and 9 attributes of the power type. To solve this problem, hand tools called wrist hand orthoses are needed to restore hand function. This study aims to design alternative designs and make prototypes of wrist hand orthoses using the 3D printing process. The research stages began by collecting activity daily living (ADL) data and anthropometric data, taking a participatory approach to produce design alternatives, selecting design alternatives with the PUGH's concept selection method. The chosen design alternative will be printed through the additive manufacturing process. Testing with the 2015 human grasping database showed an increase in grasping time in 13 types of ADL activities from 17 ADLs.
