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 paper compares the electrical conductivity of LLDPE-carbon composite materials, LLDPE-carbon-aluminum composites, and LLDPE-carbon-copper composites. Doping with aluminum (Al) and copper (Cu) metal powders influences electrical conductivity in carbon-based polymer composite materials. Adding metal powders as secondary fillers to a mixture of conductive carbon powders and LLDPE can decrease electrical conductivity. This is due to the agglomeration or clustering of metal powders within the polymer matrix, which disrupts conductive pathways and diminishes the efficiency of electrical charge transfer. The impact of filler type and quantity on electrical conductivity in composite materials was examined, and the findings revealed that factors such as the filler's amount, shape, and dispersal significantly affect the composite's electrical resistance properties. Increasing the amount of metal powder filler raises the composite's viscosity, reducing adhesion between the metal and polymer fillers while promoting metal-to-metal contacts.
