Abstract

MiFUS® is a tool that can display the patient's infusion condition so that nurses can monitor patients one by one in a short time simultaneously. Several nurses were involved in this study to provide input to the casing. Product design is done at the beginning to know the initial casing design. Next, the manufacture of casing molds is carried out using a 3D printing machine. The results of the 3D printer are used as a Master Mold for the implementation of Rapid Tooling method with Epoxy material. The solution of product development is catalyst ratio analysis on polyester resin to obtain the optimal ratio of properties including shrinkage and strength of the material to withstand mechanical loads. Validation of shrinkage is carried out using 3D Scanning technology to determine the deviation of dimensions in the casing made against CAD data. Meanwhile, to obtain the strength parameters of the material to withstand mechanical loads, tensile testing is carried out. The results of this study are the contribution of design parameters, namely the amount of shrinkage that occurs and the strength parameters of the material to withstand mechanical loads. The Data and information are presented in the form of product prototypes and user analysis feasibility studies.

Abstract

Excavator bucket teeth require high strength, hardness, and impact toughness to withstand severe service conditions involving abrasion and repeated impact. Achieving this combination of properties in sand-cast low-alloy steels remains challenging. This study investigates the microstructural evolution and mechanical properties of nickel-modified sand-cast bucket teeth subjected to a five-step heat treatment process. The material was produced by sand casting with the addition of 0.6 wt.% Ni, followed by sequential heat treatment consisting of normalizing, pre-tempering, quenching, and double tempering. Microstructural characterization and mechanical testing were conducted to evaluate the effects of the heat-treatment sequence on material performance. The applied heat treatment produced a lath martensite as the dominant microstructure with the presence of retained austenite. After the final tempering stage, the tensile strength reached 1206 MPa, with a hardness of 51 HRC, and an impact toughness of 26.1 J/mm2. The improved impact resistance is associated with retained austenite promoted by nickel addition. Fractographic analysis revealed predominantly ductile fracture characterized by dimple formation, followed by crack propagation involving intergranular and secondary cracking features. These results demonstrate that nickel modification combined with heat treatment effectively improves the mechanical performance of sand-cast bucket teeth.
