“…[115] However, there are essential properties and conditions that must also be considered when fabricating an orthosis, including strength, stiffness, durability, density, corrosion resistance, the patient's weight and activity, the patient's skin condition, and the ease of fabrication. [3,91,93,116] Table 4 lists the crucial properties that come into play in the selection of materials for making orthoses.…”

“…However, technological advancements in materials engineering and the ability to structurally design a component (e.g., modify thickness) have made certain 3D‐printed parts more suitable for use in final products than for prototypes. [ 91 ] The variety of materials is growing, practical printers are more readily available and cheaper, the computing power for running sophisticated 3D software has essentially become ubiquitous, and even access to the complex scanning process has been greatly improved. The physical characteristics of an orthotic device are ultimately determined by the material type, which, in turn, governs the device's elasticity, resilience, flexibility, durability, hardness, density, and temperature response.…”

Ankle‐foot orthoses (AFOs) assist patients with gait impairment by correcting ankle and foot deformities, restoring mobility, reducing pain, and providing protection and immobilization. AFOs can beneficially manage various types of gait pathologies, including foot drop, crouch gait, equinus gait, and stiff knee gait. AFOs are produced in prefabricated or custom‐made forms in various designs. The selection criteria for the fabrication of an AFO are the duration of usage, the amount of applied force, the degree of axial loading, the patient’s skin condition, and the cost. The accessibility of diverse materials in the past century has greatly advanced orthoses. The ideal orthotic materials must be light, stiff, and strong, and are made of plastics, metals, polymer‐based composites, leather, or a hybrid of different materials. Deeper understanding of the materials employed in the fabrication of AFOs will lead to more advanced and efficient orthoses, which can improve patients’ ability to ambulate in the real world. The present review provides insight into the various materials utilized for the fabrication of AFOs and describes the benefits and challenges associated with these materials. An attempt has also been made to highlight typical gait pathologies and design concepts in response to these.This article is protected by copyright. All rights reserved.

A number of technologies is developed that substitute simple metal cores in the high-pressure casting technology. Soluble cores, namely on the salt basis, represent the highest prospect. The contribution gives the results of the production of salt cores by high-pressure squeezing and shooting with using a binder. Special attention is paid to the shape of NaCl salt crystals with additives and the influence on strength properties of cores. A technology of bonding the salt cores is developing. Salinity of circulating water is studied and it is checked with the aid of electrical conductance.
