3D printing technology is a highly promising fast prototyping method. It is a technology that is rapidly being utilized for mass customization and manufacture of open-source designs in industries such as agriculture, healthcare, automobile, locomotive, aviation, and others. FDM is an additive manufacturing (AM) technology that creates a 3D physical object directly from a computer-assisted design (CAD) model by layering the feedstock, which is polymer filament material ejected through a nozzle. The test samples were made using Olivetti S2 3D printer and according to standard testing sizes like ASTM D638, ASTM D790, and ASTM D256. Mechanical properties: Three distinct materials, polylactic acid (PLA), carbon fiber-reinforced PLA, and carbon fiber-reinforced polyethylene terephthalate glycol (PETG) are evaluated through tensile test, flexural test, and impact test by varying the process parameters such as feed rate and infill pattern. PLA is a popular biodegradable biopolymer known for its high biocompatibility and sustainability. PETG material is a kind of chemical utilized in a variety of industrial processes due to its great durability, impact strength, and outstanding formability.
