“…Inozemtcev & Duong [28] compare the cost of building a wall using a HSLWFC (high-strength light weight fiber-reinforced concrete) with a 3D printer vs using standard methods, concluding that there could be up to between 30-50% savings, mainly due to reduction of material and machinery hours. Concrete cost was 154.0 USD /m3; however, the authors did not mention whether the cost was actually estimated or accurately calculated.…”

“…On the other hand, among the natural fibers, there are animal, vegetable and mineral fibers. All these fibers can present high modulus and tensile strength, such as basalt, carbon, glass, aramid or steel or low modulus and tensile strength, such as PE, PP, PVA [28]- [30].…”

“…In conventional concrete the percentages of fibers that have been incorporated are below 1%, because a high quantity of these notably reduces the workability of the mixtures [28], [40]. 3D printing concrete must also maintain low percentages of PP fibers, so that the mix can maintain its workability and no blockages occur in the extrusion nozzle [39].…”

3D printing of concrete structures has had a strong development in recent years, enhanced by the advantages it presents over traditional construction.However, it currently still has some limitations. One of those limitations is to incorporate the reinforcements into the automated 3D printing process. The objective of this work is to present a review of the methods that have been used so far to reinforce the structures. The different methods used will be presented focusing on the reinforcement by the use of fibers. The properties of the fibers, lengths, percentages of the same used in the mixtures will be analyzed. The results of the different tests will be shown making a comparison between the values obtained from the tests carried out with the printed and molded materials. Finally, the increases in the results of the tests that these fibers provide with respect to the samples without them will be analyzed.

“…Besides changing layer-laying techniques, there have been attempts of using a large variety of materials [2,3,[5][6][7]. While materials such as polymers promptly gained popularity because of their highly plastic behaviour and ease of forming, more rigid materials such as concrete, mortar, or clay were not in favour [3,6,8,9]. Notably, 3DP technologies brought a new level of freedom of form and shape into the building industry [4,5,10,11].…”

“…It is estimated that 34% of the cost of rising monolithic construction results from the formwork itself, and an additional 20% is generated by the work needed for its use and maintenance [2,7,12]. The use of programmed machines allows for excluding man-made errors and continuous operation in a building site [2,3,6,10].…”

The increasing popularity of additive manufacturing technologies in the prototyping and building industry requires the application of novel, improved composite materials. In this paper, we propose the use of a novel 3D printing cement-based composite material with natural, granulated cork, and additional reinforcement using a continuous polyethylene interlayer net combined with polypropylene fibre reinforcement. Our assessment of different physical and mechanical properties of the used materials during the 3D printing process and after curing verified the applicability of the new composite. The composite exhibited orthotropic properties, and the compressive toughness in the direction of layer stacking was lower than that perpendicular to it, by 29.8% without net reinforcement, 42.6% with net reinforcement, and 42.9% with net reinforcement and an additional freeze–thaw test. The use of the polymer net as a continuous reinforcement led to decreased compressive toughness, lowering it on average by 38.5% for the stacking direction and 23.8% perpendicular to the stacking direction. However, the net reinforcement additionally lowered slumping and elephant’s foot effects. Moreover, the net reinforcement added residual strength, which allowed for the continuous use of the composite material after the failure of the brittle material. Data obtained during the process can be used for further development and improvement of 3D-printable building materials.

Abstract3D concrete printing (3DCP) has developed rapidly in recent years, with a relatively high amount of mortars emerging apt for 3D printing. Some of these mortars include fibers to improve their strength. Despite mechanical properties having been quite well studied, there still is missing information on cost, printability, and environmental impacts. The objective of this research is to select the best mortars with fibers considering four criteria: printability, mechanical strength, and economic and environmental impact applying a multi-criteria decision-making analysis (MCDMA). Seven types of fibers with different dosages were assessed in the reinforced mortars: zylon, aramid, carbon, glass, cellulose, textile, and polypropylene. AHP method and equal weights were used as ponderation techniques of the criteria while WASPAS and TOPSIS methods were used to calculate the rankings of the MCDMA. Printability was measured through rheological tests using a rotational rheometer, mechanical strength through flexural tests at 28 days based on EN 196–1, and cost just considering the materials and environmental impact through a life cycle assessment (LCA). The results showed that 13-mm-long glass fibers with a content of 0.1% were the best alternative, closely followed by the mortar with 6 mm cellulose fibers with a content of 0.05%. For the best option (G13;0.1), the increments in the printability index, flexural strength, cost, and LCA were − 14.37%, 16.70%, 5.88%, and 2.86%, respectively. It can also be concluded that high elastic modulus fibers (zylon and aramid), although able to increase significantly the flexural strength (up to 30% in the case of zylon), prevent them from being an optimal solution due to their high cost.
