Investigating the Influence of Infill Pattern, a Fused Deposition Process Parameter, on the Flexural Strength of PETG Parts

A wide range of applications have shown the value of additive manufacturing technologies. A well-known manufacturing technique that many industries favour for creating intricate structures affordably is fused deposition modelling (FDM). With FDM, the user can create the desired product by melting, extruding, and depositing a range of thermoplastic materials in successive layers. Similarly, the production of FDM is unaffected by design complexity. Various factors, such as layer height, build-up orientation, infill patternsare carefully taken in the process. This study examines the flexural strength of Polyethylene Terephthalate Glycol (PTEG) components produced by FDM while taking into account the infill pattern process parameter and maintaining the same values for all other parameters. The infill patterns were changed to create the test samples while keeping all other factors the same. The ideal infill pattern for a more durable PTEG-printed part was also investigated, as well as the flexural strength of these test specimens.
