摘      要：3D printing of cementitious material can provide an affordable,sustainable,and optimized approach for the construction of homes,without compromising quality or *** most of the current research and development efforts in this field are focused on cement-based concrete printing,this paper focuses on the current state-of-the-art literature review of designing and developing a sustainable clay-based mixture design that mainly includes clay,sand,straw,lime,and *** goal of this paper is to bridge the gap between typical traditional earth construction,specifically cob construction,and emerging 3D printing of cementitious *** specific objective of this paper is to offer some possible changes in the typical cob mixture so that it can be used for 3D printing of clay-based mixtures with sufficient flowability,buildability,strength,and open time(i.e.,the time period between printing of one layer and printing of another layer deposited on a layer below).The paper describes typical clay-based mixtures and their traditional process and then specifies the challenges in going from traditional cob construction to advanced computer-controlled robotic 3D printing.
