While the use of automation and robotic systems in the construction sector has become increasingly widespread in recent years, 3D concrete printer technologies, in particular, are becoming more remarkable. Until now, developed systems have mostly been limited to single-story structures or small-scale projects, while the construction of high-rise buildings was still carried out using traditional tower cranes and human labor. However, a new system introduced by the Australian technology company Luyten stands out as a significant step that could change this situation. The company announced that it has developed the "world's first tower crane-based 3D construction printer." This system, named Ascend, can construct concrete structures up to 100 meters in height.
The Ascend system combines classic tower crane architecture with robotic concrete printing technology. According to the company's statement, this system is specifically designed for multi-story buildings, high-rise structures, and large-scale infrastructure projects. Moreover, it not only automates the concrete pouring process but also works with AI-powered software and digital construction workflows. This allows the digital design of a structure to be directly transferred to the physical production process.
According to Luyten CEO Ahmed Mahil, what makes Ascend important is not just that it's a new 3D concrete printer. Mahil states that the system transforms tower cranes, which have been fundamental components of the construction industry for years, into robotic production systems capable of direct manufacturing from digital designs. According to the company, the main goal here is not to completely change the existing construction infrastructure but to make currently used systems smarter and more automated.
Ascend Can Be Set Up and Operated in a Very Short Time
According to the technical details shared by the company, Ascend has an operating radius of approximately 45 meters. Additionally, it can construct structures reaching up to 100 meters in height. The system can also be set up and made operational within one to two days. This time advantage can be considered significant for the industry, as the installation of traditional large construction equipment can sometimes take weeks.
The software side behind the system also appears noteworthy. Ascend can create printing routes using AI-powered algorithms, optimize the construction process, and track progress in real-time. This means the system is not just a robot performing physical production; it also functions as a digital platform that analyzes and manages the construction process.
Ascend Requires a Special Concrete Material
Luyten states that the system will be used with their self-developed special concrete material called "ultimatecrete." This concrete mixture, developed for large-scale layered production, is said to offer high durability, controlled flow properties, and stronger bonding between layers. Since strong bonding between layers is critical in multi-story structures, the concrete formula used becomes a determining factor in such systems.
Of course, at this point, the cost of this special concrete, which the company calls "ultimatecrete," is of great importance. Because if it is much more expensive than standard ready-mix concrete, it will make it difficult for this technology to gain traction in the field. Luyten has not yet shared clear figures on this matter. Therefore, we do not currently know the cubic meter price of ultimatecrete. However, Luyten's general claim is that this technology will reduce construction costs by 30 to 60 percent. For this reason, it is thought that the price difference between concretes will not be very high. However, more precise information on this needs to be awaited.
The company believes that a significant portion of existing tower cranes could be converted into robotic construction systems in the future. According to Ahmed Mahil, tower cranes that shape city skylines today could transform into digital factories capable of direct production in the future. If this approach becomes widespread, a serious transformation could occur, especially in housing production, infrastructure projects, and large-scale construction processes. However, the answers to questions such as how reliable these systems will be, to what extent they can be widely adopted in high-rise structures, and how they will be integrated into existing construction standards will become clear in the coming years.
