Construction industry is very labor-intensive and one of the major sources of employment in the world. The industry is experiencing low productivity with minimum technological innovations for decades. In recent times, various automation technologies including 3D printing have received increasing interests in construction. 3D printing in construction is found to be very promising to automate the construction processes and have the potential of saving laborious work, material waste, construction time, risky operation for humans, etc. There has been a comprehensive body of research conducted to understand the recent advances, future prospects and challenges of large-scale adoption of 3D printing in construction projects. Being one the labor-intensive industries, this study also investigates the possible impact on the labor market with increasing adoption of 3D printing in construction. It is found that 3D printing can reduce significant number of labors which can solve the labor shortage problem, especially for the countries where construction is heavily dependent on immigrant workers. In contrast, 3D printing might not be favorable for the countries where construction is one of the main workforces and labor is less expensive. Moreover, 3D construction printing will also require people with special skills related to this new technology.

This article shows the results of the application of parametric design process in the digital fabrication of cellular solids inspired structures by 3d printing in model scale. Two proposal will be presented. Both are devised according to the idea of creating resistant wireframe cellular structure with zero-waste of printing material. The methodology was based in the application of three steps design science research into two different parametric patterns: diagrid and voronoi. It is shown the analytic description of both processes with 3d printed models. The conclusion is that the diagrid pattern offers better control of the design than the voronoi.

“…The image coordinate system and robot coordinate system are two-dimensional; therefore, two coordinate systems can be converted to each other by rotation, translation and scaling. Equation (3-1) is the transformation equation between two coordinate systems: R is a rotation matrix, and M is a translation matrix; (u, v) represents the point in the image coordinate system; and (x, y) is for the robot coordinate system (van Albada et al, 1994;Maoling et al, 2000;Wu and Sun, 2004). We select several points and obtain their image coordinates and robot coordinates; then, we solve equation (3-1) to obtain the relationship of the two coordinate systems.…”

“…The third category is to use mobile devices to reach the goal of large-scale manufacturing. Hunt et al (2014) presents an aerial 3D printer that can deposit polyurethane foam to create structures mid-flight; one or more mobile robots are applied in Subrin et al (2018) and Zhang et al (2018) with simultaneous localization and mapping (SLAM) technology to perform large-scale 3D printing; researchers at Tsinghua University use a laser tracker to control multiple mobile robots for large-scale operation (Jianhui et al, 2015).…”

Purpose 3D printing for objects whose size exceeds the scope of the printer is still a tough challenge in application. The purpose of this paper is to propose a visual stitching large-scale (VSLS) 3D-printing method to solve this problem. Design/methodology/approach The single segmentation point method and multiple segmentation point method are proposed to adaptively divide each slice of the model into several segments. For each layer, the mobile robot will move to different positions to print each segment, and every time it arrives at the planned location, the contours of the printed segments are captured with a high-definition camera by the feature point recognition algorithm. Then, the coordinate transformation is implemented to adjust the printing codes of the next segment so that each part can be perfectly aligned. The authors print up layer by layer in this manner until the model is complete. Findings In Section 3, two specimens, whose sizes are 166 per cent and 252 per cent of the scope of the 3D-printing robot, are successfully printed. Meanwhile, the completed models of the specimens are printed using a suitable traditional printer for comparison. The result shows that the specimens in the test group have basically identical sizes to those in the control group, which verifies the feasibility of the VSLS method. Originality/value Unlike most of the current solutions that demand harsh requirement for positioning accuracy of the mobile robots, the authors use a camera to compensate for the lost positioning accuracy of the device during movement, thereby avoiding precise control to the device’s location. And the coordinate transformation is implemented to adjust the printing codes of the next sub-models so that each part can be aligned perfectly.
