It is also recognized as additivemanufacturing(AM),additivefabrication,additive processes, direct digital manufacturing, rapid prototyping (RP), rapid manufacturing, layer manufacturing, and solid freeformfabrication[1].Suchprinterusesmaterialssuchas plastics, concrete, sand, resins, or metals [2]. Researchers studied different types of 3D printers, materials, and construction procedures to take this tech- nique forward to construct structural components and/or whole structure [3]. Tay et al. [4] presented the previous researches conducted in 3D printing. Eight categories of research topics, namely, printing techniques analysis, material analysis, control system, data analysis, architec- tural design, literature review, concept analysis, and cost benefitanalysiswereobserved.Bosetal.[5]presentedthe development of additive manufacturing of concrete and describedindetailthe3Dconcreteprintingfacilityofthe Eindhoven University of Technology. In addition, the 3D concrete printing was described in terms of geometry, conducted experimental research, and the difficulties of construction. is paper presents a state-of-the-art review of the ad- vances in 3D printing procedures. e investigation of the impactof3Dprintingisappliedbycomparingtheconcrete costofconventionallybuiltRasAlainMultipurposeHallin Jordan with the cost if it was built using 3D printing. e suggested model is generated using Revit software. 2.State-of-the-Artof3DPrintingof ConcreteProcedure e first attempt to use cement-based materials by the 3D printing procedure was suggested by Joseph Pegna [6].
