Construction projects are often challenged by tight budgets and limited resources. Contractors are looking for ways to become competitive by using methods and materials that are sustainable and cost-effective. Using sustainable 3D printing to produce cost-effective construction elements is becoming a feasible option to make contractors more competitive locally and globally. Along this line, contractors are attempting to improve production skills to satisfy certain specifications and standards while keeping costs within competitive ranges. The aim of this research is to investigate the production process capability of 3D printers using fused deposition modelling (FDM) to produce 3D-printed sustainable parts made from plastic waste for the use in the construction of buildings with different infill structures and internal designs. The production capabilities and requirements of FDM printers were first examined and possible applications in construction are then presented. The outcome of this study indicates that 3D-printers can be used to produce parts made from plastic waste using FDM printers. These parts are sustainable and less expensive as compared to some traditional non-load bearing construction elements such as lightweight concrete hollow blocks and lightweight concrete bricks since they are less expensive and have higher compressive strength. However, it is not feasible to use 3D printed material from plastic waste as an alternative for gypsum board drywalls since it is more expensive; however, it might be considered as an alternative since it provides a higher compressive strength. |
