| Abstract | ||||
| The traditional building approach in Egypt has several drawbacks. This is evidenced by the long completion time for projects, the large number of workers, and the high to average error rate. These issues lead to negative environmental impacts and a higher construction cost. These drawbacks can be efficiently remediated through the use of the emerging technology of three-dimensional printing (3DP). This study aims to showcase some of the current success stories of 3DP in lightweight structures. A comparative analysis was conducted between construction using 3DP and the conventional construction method. A SWOT analysis was also conducted for 3DP to determine its strengths and weaknesses, as well as to find out areas of opportunities and those of threats. Many of the advantages of this technology can be highlighted, including reductions in cost and time, providing safe working conditions at the designated location (less injuries and deaths), and less pollution. However, certain constraints still hinder the use of 3DP. This includes the production of firearms and medical devices that do not comply with set standards. An analytical study was conducted for certain lightweight structures, including a temporary exhibit and a bus stop. Finally, a study was conducted of the current situation of the study area and a proposal was prepared for its renovation using 3DP. A list of criteria was set that all public transport stops and stations need to abide by, as well as techniques to achieve them. The proposed design and implementation of the bus stop in the case study was found to comply with them and achieve the desired results. | ||||
