Robotic 3D printing applications are rapidly growing in architecture, where they enable the introduction of new materials and bespoke geometries. However, current approaches remain limited to printing on top of a flat build bed. This limits robotic 3D printing’s impact as a sustainable technology: opportunities to customize or enhance existing elements, or to utilize complex material behaviour are missed. This paper addresses the potentials of conformal 3D printing and presents a novel and robust workflow for printing onto unknown and arbitrarily shaped 3D substrates. The workflow combines dual-resolution Robotic Scanning, Neural Network prediction and printing of PETG plastic. This integrated approach offers the advantage of responding directly to unknown geometries through automated performance design customization. This paper firstly contextualizes the work within the current state of the art of conformal printing. We then describe our methodology and the design experiment we have used to test it. We lastly describe the key findings, potentials and limitations of the work, as well as the next steps in this research.

“…A pre-installed mesh also can be used as a support for printing inclined and curved structures. The possibility of printing on meshes was proved as a part of the SCRIM project [18], where they used tightly fixed fine textile meshes for 3D printing of various patterns; see Fig. 1b.…”

Strategies for Integrating Reinforcement Into 3D Concrete Printing at the TU Dresden

et al. 2022

3D concrete printing (3DCP) has all the chances to become the future of the construction industry, but this technology is not yet widely applicable. One of the main challenges still to be mastered is the difficulty of reinforcing printed structures. At this point, many reinforcement strategies have already been proposed, which are fully or partially capable of solving the problem. This publication provides first an overview of existing reinforcement strategies, classified according to the time of reinforcement introduction: before, during, or after 3D printing. Then the authors present the approaches developed at the TU Dresden and provide readers with information on new methods that still are in the development stage.

“…Examples include post-printing material contour crafting [ 35 , 36 ] and the removal of excess material with cutting tools [ 36 ]. A work [ 37 ] shows the use of a six Dof manipulator to deposit concrete on a textile mesh at different orientation angles.…”

“…In the case of printing with simultaneous contour crafting of the fresh mix, a better print surface is obtained, which allows for reducing the technological regime of printing [ 46 ]. If we consider printing the mix on a textile mesh [ 37 ], its flow limit can be much lower than when printed without a support material.…”

Foundation Piles—A New Feature for Concrete 3D Printers

et al. 2021

Foundation piles that are made by concrete 3D printers constitute a new alternative way of founding buildings constructed using incremental technology. We are currently observing very rapid development of incremental technology for the construction industry. The systems that are used for 3D printing with the application of construction materials make it possible to form permanent formwork for strip foundations, construct load-bearing walls and partition walls, and prefabricate elements, such as stairs, lintels, and ceilings. 3D printing systems do not offer soil reinforcement by making piles. The paper presents the possibility of making concrete foundation piles in laboratory conditions using a concrete 3D printer. The paper shows the tools and procedure for pile pumping. An experiment for measuring pile bearing capacity is described and an example of a pile deployment model under a foundation is described. The results of the tests and analytical calculations have shown that the displacement piles demonstrate less settlement when compared to the analysed shallow foundation. The authors indicate that it is possible to replace the shallow foundation with a series of piles combined with a printed wall without locally widening it. This type of foundation can be used for the foundation of low-rise buildings, such as detached houses. Estimated calculations have shown that the possibility of making foundation piles by a 3D printer will reduce the cost of making foundations by shortening the time of execution of works and reducing the consumption of construction materials.
