- ItemPellet 3D printer(2024-09-26) Osama Muhammad Daoud; Sabeeh Omar Daher; Abdullah Wael Fakhry Ass3D printers will undoubtedly continue to increase the capabilities of small- and mid-sized manufacturers well into the future. The most exciting advances are yet to come. And the biggest winners out there will be the manufacturers with the vision to foresee the possibilities these revolutionary machines can unlock. This report focuses on the design and development of a Pellet 3D printer Starting from the mechanical design, then the electric and controller selection, followed by the software, programing. Throughout this project, we delved into various 3D printing methodologies, focusing on Fused Deposition Modeling (FDM). This falls within the realm of additive manufacturing (AM), where filament, such as PLA material, serves as the primary material. FDM employs a three-mechanism movement, and for our project, we utilized the Creality Ender 3 printer, which operates on a conventional 3-axes CNC mechanism. Then we talked about plastic extrusion, a process involving the melting and shaping of raw plastic. Subsequently, we embarked on the task of designing a novel printer head using Creo Parametric. This included creating essential components through 3D printing, assembly of the extruder, and its installation onto the printer, replacing the original head. The final step involved calibrating the printer, this step is the most important step where we will make the controller deal with the mass of pellets instead of the length of filaments, setting the stage for its subsequent use in the examination of diverse material samples.

- ItemPolymer Melt Flow in 3D Printing(2024-02-12) Ahmed Qadi; Abdul Hakim FutyanAbstract Material extrusion additive manufacturing is a widely used process for producing complex parts from thermoplastic polymers. However, the quality of the final product is heavily influenced by the flow behavior of the polymer melt through the hot-end and the nozzle. In order to optimize the extrusion process, reduce defects such as extrusion inconsistencies, and improve the quality and performance of the final product, a comprehensive understanding of the flow behavior is essential. In this project, the flow behavior of polymer melts in fused filament fabrication 3D printing technology through the extrusion mechanism known as the hot-end will be investigated experimentally. A test setup was built to extrude polymer melts at different melt temperatures while measuring the force exerted using load cell. The goal is to develop a control system that can optimize the extrusion process and interpret the force data to achieve optimal results. Additionally, a key objective of this study is to conduct a comparative analysis of PLA (Polylactic acid) and TPU (thermoplastic polyurethane) materials, assessing how each responds to varying extrusion conditions. This comparison aims to uncover the distinct properties and behaviors of these polymers, offering valuable insights for their application in 3D printing. The results of this comparison are crucial for understanding material-specific requirements and tailoring the extrusion process accordingly. Data from the test setup were collected and analyzed using MATLAB. A key challenge encountered was the non-linear behavior of the heater model, which led to the development of the advanced Hammerstein model. However, due to complexities in designing a controller for this model, a PID Controller was employed. Utilizing MATLAB's PID tuner, optimal values for Kp, Ki, and Kd were determined to effectively control the heater. The study demonstrates that extrusion parameters like speed, temperature, and feeding force critically affect the quality of 3D prints. It thoroughly investigates how these factors interact, enhancing our understanding of their role in 3D printing. This research significantly advances the field by providing deeper insights into material properties and suggesting ways to improve 3D printing techniques, laying groundwork for future advancements
- ItemPhotovoltaic Grass Cutter(2024-02-07)The continuing increase in fuel costs and the impact of gas emissions from burned fuel into the atmosphere makes it necessary to use the sun's plentiful solar energy as a source of electricity to run a lawn mower. Based on the fundamentals of mowing, a solar-powered lawn mower was created. The direct current (D.C.) motor, a rechargeable battery, a solar panel, a stainless-steel blade, and a control switch make up the intended solar lawnmower. An app is used to operate the solar- powered lawnmower, which shuts the circuit and allows current to pass through the motor, which drives the blade used for cutting grass. Through the solar charging controller, the battery is recharged.
- Item3 axis laser engraver CNC machine(2023-06-19) Tha’er Dwikat; Abd Alhameed BahishABSTRACT CNC technology has become a requirement in the industrial world, manufacturers of this type of machine are trying to conform to the market requirements in terms of quality, price, and quantity, and so the CNC machine can meet the requirements and has acquired a leading position. Using CNC machines is more cost-effective, accurate, and much faster. It’s the ability to manufacture complex shapes with high quality and accuracy compared to the ordinary machines. The vast majority of today’s CNC arsenals are completely electronic. Some of the more common CNC-operated processes include ultrasonic welding, hole-punching and laser cutting. In this final project, a 3-axis laser engraver CNC was designed and developed, that has two linear axis and one rotational axis capable of engrave "draw" on cylindrical parts. Starting from the mechanical design, then the electric and controller selection, followed by the software, programing and finally the results and dissolution.
