“…During the Izod impact test, the sample is held vertically with the notch facing the pendulum, while during the Charpy impact test, the sample is held horizontally with the notch facing away from the pendulum. 28 In this study, the Charpy impact test machine of Novavaran Baspar Co. was used to evaluate the impact resistance of printed PLA/iron samples. The IS was calculated by dividing the absorbed energy before the failure by the cross-section area of the sample in the failure location.…”

Polylactic acid (PLA) is the most widely used material in the fused filament fabrication (FFF) technique, which is a biocompatible thermoplastic. However, PLA's usefulness is limited by its narrow processing window and relatively low mechanical properties. Therefore, PLA composites have been developed to enhance its properties for FFF printing. A key challenge in producing composite parts via this method is to find the correlation between the mechanical properties of the parts and the process parameters. This knowledge is essential for optimizing the printing process to achieve the desired mechanical properties for composite parts industries such as aerospace, automotive, and medical, where high‐performance composite materials are crucial. The ability to control and predict the mechanical properties of FFF‐printed composite parts is critical for their successful integration into these industries. In this study, the effect of nozzle temperature (NT), printing speed (PS), and nominal porosity (POR) on the impact strength and specific impact strength of PLA/iron composites was examined using FFF. Response surface methodology (RSM) was used to optimize the experimental design. The results revealed that POR had the most significant effect on the impact resistance data, while NT had the least effect. Reducing the POR led to improved impact resistance in the samples. Multi‐objective optimization results showed that the lowest NT (190°C), the lowest POR (30%), and a PS of 50 mm/s were the optimal conditions for multiple objectives. RSM was also utilized to develop mathematical models of impact properties, focusing on varying NT, POR, and PS, which can be used to predict desired impact properties.Highlights Nominal porosity has the most influence on the impact strength of PLA/iron composites. Optimum values were temperature of 190°C, nominal porosity of 30%, and speed of 50 mm/s. RSM was effective in enhancing the mechanical properties of composite materials. RSM models provide a predictive tool for future FFF‐printed composite parts. Maximum impact strength of 4.44 kJ/m2 was achieved.

“…After the thermometer holder was designed in SOLIDWORK, the next step is to create the thermometer holder by using 3D printing. The material that has been chosen to create the product is stereolithography (SLA) [17][18][19][20]. After all of assembly and painting have been done, the structure must be covered by Aluminum Composite Panel (ACP).…”

This research project aimed to transform a common temperature scanner stand into a user-friendly adjustable stand holder temperature scanner. The temperature scanner automatically adjusts its height according to the user's height, reducing the risk of contact infection by using an ultrasonic sensor to detect the user in front of the scanner. The experiment involved measuring the time taken for the thermometer to move from the starting position to the maximum height of different individuals with varying heights. A frame capture application on a smartphone was used to record the motion and time, capturing data at a rate of 33 frames per second for accuracy. The tests were conducted using a constant motor speed of 100 revolutions per minute. The results showed that the duration of waiting time for the adjustable stand holder temperature scanner was valid for individuals with heights ranging from 100 cm to 180 cm. The constructed adjustable stand successfully served its purpose and demonstrated functionality and reliability in real-life testing. To improve the accuracy and expand the capabilities of the adjustable stand holder temperature scanner, future work are needed such as utilizing smart system programs to cater to user preferences, implementing material modifications to reduce vibrations, and introducing additional features to indicate a person's height and weight.
