Abstract

Thermoplastic polymers have several uses in all sectors of industrial activity, such as automotive, agricultural, aeronautical, and other industrial applications, like home accessories. For this purpose, they have different forms assured by three principal processes: Injection, extrusion, and additive manufacturing, known as new technology and process based on CAD (computer-aided design), by using raw materials in form of powders or filaments, called 3D printing. The 3D printer’s size affects the filament’s diameter used (1,75/2,5mm). Because of the expensive price, permanent mechanical properties and chemical composition of the filaments, and the useless waste plastics. A design of a 3D printer filaments extruder based on 3D software was adopted. Furthermore, a testbed of this one was manufactured.However, this is about creating and producing the filament used while having the thermoplastics in the form of pellets, granules and waste plastic materials. In fact, this proposed solution solves all the issues set previously and help to improve the mechanical properties, so that the behavior can be changed by adding other polymers, (combining two polymers or more).
