Abstract

The need to show the geometry of a workpiece of a component or system on a certain scale and three-dimensionality can be realized through a three-dimensional printing press. This paper explains the techniques and how to design a three-dimensional printing machine and test product printing. The three-dimensional printing machine has been successfully created and built, and the printing test shows the results corresponding to the machine's specifications. The design and fabrication of printer 3D printing machine for PLA filament thermoplastic material has been successfully done. This machine implements an Arduino Mega 2560 R3 CH340G-based control system. The specifications of the 3D printing machine are as follows: Layer height = 0.2 [mm]; Infill density = 20%; Maximum Printing temperature = 240°C; Build plate temperature = 60°C; Print speed = 60 [mm/s]. The input comes from an AC power source that is converted to DC with an Input Power supply of 12 Volt 20 A. The machine has been tested, and parts with geometry are produced according to the machine's specifications.

Abstract

This study aims to develop composites using electrically conductive carbon and polymer polyethylene (LLDPE) to enhance electrical conductivity. Investigations have been conducted on the fabrication of electrically conductive composites and the modulus of elasticity through heat compaction using mixtures of carbon-LLDPE powders. Heat compaction is performed at temperatures ranging from 120°C to 150°C, with varying composition ratios of carbon-LLDPE, including 50:50, 60:40, and 70:30 % wt. Higher proportions of carbon and compaction temperatures are correlated with increased electrical conductivity. For instance, the C7-3LLDPE composite, compacted at 150°C, demonstrates the highest electrical current flow of 0.0018 A, whereas the C5-5LLDPE composite, compacted at 135°C, exhibits the lowest current flow at 0.0000638 A. Regarding the modulus of elasticity, the composition ratio of C7-3LLDPE, compacted at 120°C, achieves the highest value at 2686.43 [N/mm2 ]. Conversely, the composition ratio of C5-5LLDPE, compacted at 135°C, yields the lowest modulus of elasticity at 1530.94 [N/mm2 ]. Elasticity modulus testing follows the ASTM D638 standard, with a speed of 2 mm/min. It is observed that increasing the compaction temperature results in a decreased modulus of elasticity across all composition ratios. Furthermore, a higher carbon content within the composite corresponds to a higher modulus of elasticity, regardless of the compaction temperature.

Abstract

The use of low-cost sensors controlled by open-source microcontrollers (Arduino, ESP32) is investigated in this study not only to measure electrical, thermal, and magnetic values ​​but also to investigate intrinsic material properties such as thermal conductivity and magnetic strength. Four sensors are used in this study such as SS49E, MAX6675, ACS712, and HMC5883L. Their performance is evaluated in monitoring a carbon rod subjected to 29.9 V DC current and the measurement results are displayed on a 20x4 I2C LCD and stored in CSV format on an SD Card. The MAX6675 thermocouple sensor shows the most stable and reliable results for surface temperature measurement, which is supported by reference multimeter readings. However, the use of multiple sensors simultaneously reveals interference issues, indicating the need for electrical isolation or signal multiplexing in future designs. This study contributes to the advancement of affordable open-source instrumentation as a viable alternative to commercial measurement tools, emphasizing the shift from raw signal acquisition to meaningful property computation.
