Abstract

Fused deposition modelling (FDM) is a rapidly growing 3D printing technology. However, printing materials are restricted to acrylonitrile butadiene styrene (ABS) or polylactic acid (PLA) in most Fused deposition modelling (FDM) equipment. Here, this project on a new high-performance printing material, Carbon Fibre reinforced ABS, which could surmount these shortcomings. This project is dedicated to studying the influence of layer thickness and fill angle on the mechanical properties of 3D-printed specimens. Specimens with three different layer thicknesses (0.18mm, 0.25mm and 0.31mm) and fill angles (30º, 45º and 90º) were built using a 3D printing system and their flexural strengths were tested. The optimal mechanical properties of ABS specimens were found at a layer thickness of 0.25mm and a fill angle of 45° and for Carbon Fibre reinforced ABS obtained 0.18mm layer thickness and 45° fill angle. To evaluate the flexural properties of Carbon Fibre reinforced ABS specimens, a comparison was made between the mechanical properties of 3D-printed Carbon Fibre reinforced ABS and acrylonitrile butadiene styrene (ABS) parts.
