Abstract- Thermoplastic polymers find extensive
physical properties, they are often expensive and largely imported. To address cost concerns and promote environmental sustainability, waste plastics are incorporated into the process. To further enhance the properties of the 3D-printed parts, modifications to the fused deposition modelling (FDM) printing technique have been undertaken. A crucial aspect of this project involves designing and realizing a testbed for a filament extruder capable of producing filaments at specific diameters of 1.75mm and 2.5mm. The project's objectives include the development of a low-cost filament extruder machine for extracting filament suitable for 3D printing. Subsequently, a comparative study investigates the mechanical properties of the produced filaments compared to those commonly used in the automotive industry. Mechanical tensile tests are conducted using an MTS Tensile Testing Machine with varying crosshead speeds, in line with testing standards. Specimens with diameters of 1.75mm and 2.5mm and a total length of 200mm are examined, employing a crosshead made of PA6 known for its widespread use in various industrial domains despite its limited UV resistance.

1.1 Research problems
applications across various industrial sectors, including automotive, agricultural, aeronautical, and home accessories. Their versatility is realized through three primary manufacturing processes: Injection molding, extrusion, and additive manufacturing, commonly referred to as a new technology driven by Computer-Aided Design (CAD). This innovative approach involves the use of raw materials in the form of powders or filaments, known as 3D printing, where the filament diameter (ranging from 1.75mm to 2.5mm) is influenced by the size of the 3D printer. Addressing challenges such as the high cost, permanent mechanical properties, and chemical composition of filaments, as well as the generation of wasteful plastics, led to the adoption of a solution. This solution focuses on the creation and production of filaments by utilizing thermoplastics in the forms of pellets, granules, and waste materials. Notably, the proposed solution aims to resolve previous issues and enhance mechanical properties, allowing for the modification of filament behavior through the addition of other polymers, including the combination of two or more.
1.INTRODUCTION 3D printing technologies, also known as Additive Manufacturing (AM), have revolutionized the production of physical parts using various materials such as thermoplastics, composites, and metals. This innovation has found applications in diverse industries, including aerospace and automotive, allowing for the creation of intricately designed components without the need for expensive tooling. The technique involves building up successive layers of raw thermoplastic materials, particularly utilizing polyamide (PA), acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), polycarbonate (PC), and polystyrene (PS). Despite the widespread availability of these thermoplastics with favourable mechanical, chemical, and
