Inter-operational surgery supplies manufactured additively using the FDM (Fused Deposition Modelling) technology are required to be sterilized before use. After manufacturing, the part should be sterilized using one of commonly used processes, without losing its dimensions and shape. The paper presents studies on manufacturing and sterilizing samples made out of ABS material and influence of the sterilization process on the dimensional accuracy of these samples.

The paper presents the design and manufacturing process of an individualized wrist orthosis. The patient’s upper limb was 3D scanned and the orthosis was designed using a CAD system. Each part of the orthosis consists of two different materials that fulfill different functions. By using the double-head Fused Deposition Modelling machine it was possible to produce these parts in a single process without the need for additional assembly operations. The orthosis has been tested for mutual fit of parts, strength and comfort of use.

The article presents analysis of mechanical properties of specimens fabricated by fused deposition modeling (FDM). The four of considered materials are the well-known 3D printing filaments i.e., polylactide (PLA), Nylon 12 (PA12), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate glycol (PET-G). The other four of the considered materials are composites with carbon i.e. polylactide with carbon fiber (PLA-CF), Nylon 12 with carbon fiber (PA12-CF), acrylonitrile butadiene styrene with carbon fiber (ABS-CF), polyethylene terephthalate glycol with carbon fiber (PETG-CF). The paper describes how the specimens were designed, printed, subjected to tensile testing, and examined using microscopy. The obtained data will be used to select the optimum material for the rapid manufacture of lower limb orthoses. Carbon composites were found to have better mechanical properties of their base material, but the fabrication of composite samples is much more time consuming, for the reason that the manufacturing process is not stable.

The article provides readers with a detailed overview of the AutoMedPrint technology, its advantages and opportunities, based on a number of studies and case examples. The AutoMedPrint system represents a significant advancement in the field of orthopedics, offering a comprehensive solution for the automated design and rapid production of personalized orthopedic and prosthetic devices through 3D printing technology. This paper details the system's capabilities and methodologies behind it, which include the design and manufacturing of various devices such as wrist hand orthoses (WHO) and ankle foot orthoses (AFO), among others. These devices are crafted using data obtained from precise anthropometric measurements, allowing for high customization to meet individual patient needs. The AutoMedPrint system enhances the quality of life for patients by providing devices that are not only functional and cost-effective but also rapidly produced, ensuring timely intervention. Case studies demonstrate the system's effectiveness in practical scenarios, highlighting its potential to revolutionize orthopedic care by integrating new materials and technologies that adapt to changing medical and patient requirements. The discussion extends to the lifecycle of the produced devices, emphasizing sustainability and continuous improvement, ensuring the system's relevance and efficacy in modern medical practice.
