In the manufacturing of parts, additive manufacturing using 3d printing is playing a very important role by providing an alternative to the existing conventional manufacturing processes. The strength of 3D printed parts is still in its infant stages and an area of current research. Polyethylene terephalate glycol modified (PETG) is a modified version of PET which is most commonly used plastic in the world. It is a biodegradable and recyclable material and is also one of the most compatible materials in Fused Deposition Modelling (FDM) based 3D printing modelling. According to the ASTM standards testing on PETG material is done as per ASTM D638 type-I standard. In the project, ASTM D638 type-IV, D695 specimens have been printed on a GARUDA 3D FDM printer using the PETG material and are subjected to tensile test by changing the infill percentages and layer height parameters respectively. The process involves preparation of specimens according to ASTM standards in CATIA V5 software followed by slicing using the SIMPLIFY 3D software. 3-D printing of PETG material is done on a GARUDA 3D printer. The experimental results are then to be validated using the ANSYS simulation software and the difference in the experimental and simulated values are calculated.
