Construction has just begun on the Tor Alva, or the White Tower, the world’s largest 3-D printed tower. Designed by architects Michael Hansmeyer and Benjamin Dillenburger and printed with concrete by the technology university ETH Zurich, 8 out of 32 structural columns have been completed. Nestled in the village of Mulegns in the Swiss Alps, the White Tower is designed as a venue for music and theater events. Standing at 30 meters, the design features 32 distinct Y-shaped columns, each boasting a pattern of textured details.
Historically, architecture has served as a canvas for artistic expression. Building elements have been adorned with relief-carved garlands, inscriptions, fresco murals, portrait busts, and classicizing figurative sculptures, all of which emphasize the unique and intentional nature of each component. However, the industrialization of the 19th century brought about a shift in ideals, that stripped architectural components of their decorative elements. Instead, it preferenced the search for beauty in standardization and the economic accessibility provided by mass-produced building elements.
But is there room for artistry within mass production? Can artists be involved in the industrial-making processes of building elements? And how can new technology facilitate artistic mass customization of building components? These questions prompt us to consider the potential for expression, communication, and reflection in the craft of building elements in both interior and exterior spaces.
As an additive manufacturing method, 3D printing has been characterized by the construction of objects through the horizontal deposition of material, layer by layer. This still restricts, nonetheless, the manufacture of elements and limits the shape of early prototypes to within the range that allows the addition of material in a single direction, making it difficult to create complex shapes with smooth curves.
However, the team from the Chair of Digital Construction Technologies at ETH Zurich—integrating computational design, digital manufacturing, and new materials—has been exploring an innovative non-planar robotic additive manufacturing system. This method facilitates the printing of thin structures with double curvature, significantly expanding the possibilities of their application in architecture on a larger scale.
Advancements in 3D printing technology are progressing at an unprecedented pace, accompanied by a parallel surge in computational power for manipulating and creating intricate geometries. This synergy has the potential to offer architects an unprecedented level of artistic freedom in regards to the complex textures they can generate, thanks to the technology's remarkable high resolution and rapid manufacturing capabilities. If the question of production was out of the way, and architects could now sculpt virtually anything into a facade effectively and efficiently, what would they sculpt?
3D printing holds vast potential due to its ease of large-quantity manufacturing, its flexibility in terms of material exploration, and its ability to materialize all kinds of geometries. This year, architects and designers have looked at 3D printing technology to decarbonize construction materials, integrate contemporary aesthetics with traditional construction methods, and add a layer of craft and artistry to interiors and facades.
Innovative materials play a crucial role in shaping the future of architecture. They offer not only novel ways to craft buildings but also sustainable and efficient solutions to address pressing environmental challenges. Architects and designers are now more than ever exploring and integrating innovative materials into their projects. By harnessing the unique properties of these materials, they create structures with new visual languages while also being environmentally friendly.
As part of our year-in-review, we reflect on the innovative materials that were featured. These materials delved into the concepts of recycling agro-waste, adapting bio-based products, transforming local materials, and decarbonizing concrete. The objective was not only to offer alternatives to traditional construction practices but also to help reduce carbon emissions and promote a more sustainable built environment. In this dynamic field, these materials demonstrate the potential to revolutionize building design and construction in diverse contexts, paving the way for a more sustainable and resilient future.
Harnessing the power of moldless manufacturing through large-scale robotic 3D printing, research at ETH Zürich in collaboration with FenX AG delves into the use of cement-free mineral foam made from recycled waste. The objective is to build wall systems that are monolithic, lightweight, and immediately insulated, minimizing material use, labor requirements, and associated costs.
QS- Quacquarelli Symonds World University Rankings just announced the 2023 top universities to study Architecture and the Built Environment. The index rates over 1,400 schools and covers a total of 54 disciplines, grouped into five broad subject areas, based on five indicators "to effectively reflect their performance, taking into account academic reputation, employer reputation, and faculty research".
As a response to global challenges such as climate change, discrimination, and physical vulnerability, designers and engineers from across the world have developed innovative construction materials that put the human wellbeing first in urban, architecture, and interior projects.
In order to help architects and students to get to know the best International Master’s available in the world, BAM’s annual ranking compares and evaluates programs, from the best schools of architecture, through a comparative and objective methodology, developed by 13 international experts. For the 2022 edition, different Master’s Degree Programs from the recent QS Ranking – Architecture / Built Environmenthave been selected to take part in BAM’s Ranking.
Similar to previous years, in 2022, Harvard and Columbia maintained their leading positions in first and second place. MIT made a comeback to the list with two master's programs, in the fourth position, the Master of Science in Architecture Studies in Urbanism (SMArch Urbanism), and in the sixth position, the Master of Science in Architecture Studies in Design (SMArchS Design). Universidad Politécnica de Madrid and ETH Zurich were both ranked third, offering the best master’s program in Europe. Pontificia Universidad Católica in Chile occupied the 18th position, presenting a top master's degree in South America, followed closely in the 20th position by the Universidade de São Paulo.

Delft University of Technology in the Netherlands took the second place while UCL, in the United Kingdom, came third. ETH Zurich, Harvard, and the National University of Singapore (NUS) maintained fourth, fifth, and sixth place. The Manchester School of Architecture was upgraded to seventh position this year, moving the University of California, Berkeley (UCB) to eighth place and the Tsinghua University in Beijing, China to the ninth. Politecnico di Milano, in Italy, remains a non-mover at 10.
Dübendorf, Switzerland is something of hallowed ground for architectural technologists. There, on the shared academic campus of the Swiss Federal Laboratories for Materials Science and Technology and the Swiss Federal Institute of Aquatic Science and Technology, public university ETH Zurich has conducted nearly a decade of engineering and construction experimentation at the ever-evolving NEST research building. In August, ETH Zürich unveiled its latest extension of the building, HiLo (short for high performance-low emissions)—a two-story modular addition to the chameleon structure that harnesses medieval building principles and contemporary digital methods to raise the bar for more sustainable applications of concrete.
With the aim of generating a significant impact on the responsible and sustainable consumption of resources and energy in the construction industry, ETH Zürich in collaboration with FenX AG is using foam 3D printing (F3DP) to manufacture geometrically complex formwork for the construction of special elements in concrete.

Like most functions in recent months, this year’s Digital FUTURES, which is held annually since 2011 at Tongji University in Shanghai, had to move online due to the pandemic. The organizers took this as an opportunity to give the event a global dimension, turning the festival into what they rightfully call the most significant worldwide event for architectural education ever staged, with a 24/7 display of workshops, lectures and panel discussions involving some of the most prominent architects and educators. Here is an overview of the festival, together with a selection of lectures from Digital FUTURES World.
