Computerized manufacture innovation, known as 3D printing or additive manufacturing, makes actual design from a mathematical portrayal by progressive option of materials. 3D printing depends on assembling an eventual outcome through a layer-by-layer process. Specialty figured out polypropylene copolymer supported with high-modulus slashed carbon fibre of 15% is contemplated. The microstructure and mechanical properties of the 3D printed examples were portrayed utilizing scanning electron microscope, standard tensile testing, impact testing (Charpy) and flexural testing. It was seen that polypropylene copolymer with 15% chopped carbon fibre were scattered all through the microstructure of the polypropylene copolymer. The review was made with various infill designs like network, triangle, tri-hexagonal and cubic. The test values of elasticity for various infill designs like grid, triangle, tri-hexagonal and cubic were 8.47 N/mm², 8.99 N/mm², 9.98 N/mm² and 12.05 N/mm² separately. The test values of impact strength (Charpy) for various infill patterns like grid, triangle, tri-hexagonal and cubic were 5.4 joules, 3.6 joules, 5.9 joules and 5.7 joules separately. The test values of flexural specimen for various infill designs like grid, triangle, tri-hexagonal and cubic were 1359.5 N/mm², 1205.71 N/mm², 990.4 N/mm² and 848.92 N/mm² separately. After performing a tensile test, the characterisation was done through SEM the behaviour of fracture was discussed. [ABSTRACT FROM AUTHOR]
