A folly in a Rotterdam suburb draws on residents' complex relationship with the city.The residents of Carnisselande, a garden suburb in Barendrecht, the Netherlands, have a curious relationship with Rotterdam. Many of them work in the city, or are otherwise mentally and emotionally connected to it, yet they go home at night to a place that is physically and visually separate. When NEXT architects was tapped to build a folly on a hill in the new town, they seized on this apparent contradiction. “This suburb is completely hidden behind sound barriers, highways, totally disconnected from Rotterdam,” said NEXT director Marijn Schenk. “We discovered when you’re on top of the hill and jump, you can see Rotterdam. We said, ‘Can we make the jump into an art piece?’” NEXT designed The Elastic Perspective, a staircase based on the Möbius strip. “The idea of the impossible stair [is] you’re not able to continue your trip. At first it seems to be a continuous route, but once you’re up there, the path is flipping over,” explained Schenk. “That’s a reference to the feeling of the people living there.” To catch a glimpse of Rotterdam, users must turn their backs on Carnisselande. Yet while the view is in one sense the destination, the staircase ends where it started, in the reality of the garden suburb. NEXT began by experimenting with strips of paper and thin sheets of steel to form the staircase’s basic shape. The architects then turned to AutoCad, where they finalized the design before 3D printing a 1:200 scale model. NEXT worked with engineers at ABT throughout the process. They relied heavily on 3D design software, Schenk said, “because all the steel was sort of double-curved.” Mannen van Staal fabricated the staircase from seven steel panels custom-cut with a CNC machine, said project architect Joost Lemmens. They bent the plates, largely by hand, and assembled the entire structure in their factory, temporarily welding the pieces together. They then disassembled the structure for transport to the site, where the components were re-welded by hand and using a vacuum-cleaner-sized robot. Cor-ten was a practical choice on the one hand because the rust obscures the stitches used to reconnect the seven panels. In addition, said Schenk, “It’s weatherproof, and sustainable in the sense that we’re not using a toxic coating.” The choice of Cor-ten also holds aesthetic and cultural meaning. The orange of the staircase contrasts with the green of the hill. Plus, “it’s a material quite often used in artworks, so of course it refers to the work of Richard Serra [and others],” said Schenk. “I think in short what it’s about is the idea of making a jump, make people be able to make a jump to see the skyline of the city,” he concluded. “We’re using the Möbius strip to express the ambiguity of the people living there: feeling connected to Rotterdam but being somewhere else.”
Smith|Allen's 3D-printed forest refuge is inspired by the site's patterning and historical cycle of deforestation and regeneration.When Brian Allen and Stephanie Smith first visited the sequoia forest in Gualala, California, they saw patterns everywhere. “We were really intrigued by patterning at many scales, from bark on the trees to light through the trees and also, at a micro scale, [the cells of] the sequioas,” said Allen. Two months later the pair was back, this time with 580 sculptural bricks forming the world’s first 3D-printed architectural installation. Translucent white and 10 by 10 by 8 feet in size, Echoviren resembles a cross between a teepee and a tree stump, a mass made light by the organic porosity of the bricks. Echoviren is intimately tied to its site on the grounds of Project 387, the residency in which Smith|Allen participated last fall. Besides the sequioas’ patterning, the designers drew inspiration from the primitiveness of their surroundings. “The overall form was driven by what is the most basic space we could make,” said Allen. “It turns [out to be] just a small oblong enclosure with an oculus, a small forest hermitage.” The oculus draws the eye up, to the natural roof formed by the sequioas’ branches. In addition, Smith|Allen address the history of the site as a place where regrowth followed the trauma of deforestation. Built of bio-plastic, Echoviren has an estimated lifespan of 30-50 years. “The 50 year decomposition is a beautiful echo of that cycle” of deforestation and resurgence, said Allen. Smith|Allen took a flexible approach to Echoviren’s design, alternating between analog and digital tools. They used tracing paper to extract patterns from photographs of sequoia cells, then trimmed and propagated the patterning by hand. “We initially tried to do it parametrically in Grasshopper, to replicate that cell structure as a generative tool, but we weren’t getting good results,” explained Allen. “For us, the parametric tools were more of a tool set than a generator.” Smith|Allen used KISSlicer to estimate the time required to print Echoviren, 10,800 hours in all. The designers ran seven consumer-grade Type A Machines Series 1 desktop 3D printers for two months straight. They used plant-based PLA bio-plastic, which in addition to being biodegradable, is also readily available. “We wanted to use something commercially available and easy to get our hands on,” said Allen. “The project was not about using inaccessible materials; accessibility gave us the tools to do this.” On-site assembly took four hours. Echoviren is a snap fit system, with dovetail joints in the XY and a pin and socket in the Z. Silicon adhesive secures each layer of bricks to the next. The bottom ring of bricks nestles within a hand-dug trench. Pyramidal in section, Echoviren is a compression structure. Its components vary in thickness from 6-8 inches at the bottom to less than an inch at the top. For Smith and Allen, the magic of Echoviren is twofold. First is the anticipation of the future, of the way the form will change as it decomposes. Just as important is how the installation came to be, how the technology of 3D printing enabled a firm of two to build Echoviren in less than a season. “As young designers, we struggle with getting our work out there and getting it built,” said Allen. “Using 3D printers, we’re able to really increase the amount of stuff we can do in a given time and transition it from a tool of prototyping and model building into real things.”
A cross-section of postdigital design work illustrates the role of parametrics in the built environment.Spawned from his 2011 show on Patrick Jouin, Museum of Arts & Design (MAD) curator Ronald Labaco conceived Out of Hand as a more comprehensive show that clarified the role of digital design, from its capabilities to its significance in our daily lives. “People just didn’t get it,” said Labaco of Jouin’s 2011 MAD show. “Unless you’re immersed in it, it can be hard to understand so I thought if we showed something like this in the galleries again, we needed to provide information that can be digested more clearly.” Staged across three floors of the museum, with two exterior sculptures, Labaco said the show is an important program for MAD among other New York art institutions like MoMA, Cooper Hewitt, and the New Museum. The goal to raise awareness of 3D printing is timely, by chance. “Paolo Antonelli’s Design and the Elastic Mind, and two shows from Material Connection were complements to my show for the uninitiated,” Labaco explained. Out of Hand’s broad scope includes digital designing and fabrication processes like CNC milling, digital weaving and knitting, laser cutting, and 3D printing to display how these technologies influence the built environment. “It’s a historical look at the last 8 years and works from as early as 2005 are incorporated because, in my mind, that was when the major shift between rapid prototyping and 3D printing really occurred,” said Labaco. Organized in six themes, a cross-section of traditional methods and new design capabilities are illustrated by architects crafting art, artists doing design, and photographers making sculpture. Approximately half a dozen pieces were commissioned for the show while others were an extension of existing works: For example, a chair by Jan Habraken evolved into the more comprehensive Charigenics. Placards for each piece call out production methods, from 3D printing (10 materials are featured) to digital knitting, underscoring the multi-step creation process to make the point that digital design isn’t only press-and-print. And many of the show’s pieces are a combination of old-world handcrafting and newer digital geometries and computations. Pieces like Rapid Racer, Bosch’s 3D-printed vehicle fabricated over 10 days and weighing just 29 pounds, and Zaha Hadid’s Liquid Glacial "Smoke", a coffee table CNC-milled from polished plexiglass, illustrate the functional role of digital design. Data input is actively incorporated through two interactive pieces from Francios Brument, for which he developed his own scripting, as well as a Shapeways workshop that is open to the public. Traditional forms are realized by new methods in Nendo’s 3D-printed paper boxes that are lacquered with traditional urushi for a ringed faux bois. Other featured artists, architects, and designers include Richard DuPont, Greg Lynn, Anish Kapoor, Marc Newson, Frank Stella, Daniel Libeskind, and Maya Lin. Just as dynamic as the digital disciplines themselves, new pieces are being added throughout the show’s run. Look for a new piece from Iris Van Herpen by mid-November. Out of Hand will remain on view through July 6, 2014.
A team of SCI-Arc–trained architects establish a sweet set up in Southern California.Liz and Kyle Von Hasseln wanted to bake a birthday cake for a friend but, unfortunately, their rented apartment didn't have an oven. Not to be deterred, the Southern California Institute of Architecture (SCI-Arc) alumni hit upon a solution that would leave most bakers scratching their heads: They decided to 3D print one. Earlier that year, the couple had been awarded the school's inaugural Gehry Prize for their work on Phantom Geometry, a 5-axis fabrication study of UV-cured resin within a shallow vat system that responded to real-time feed back and feed-forward mechanisms. "In our graduate work, we were really interested in the way free form fabrication would influence architecture," Kyle recently told AN. "We thought a lot about the potential for the intersection of culture and technology that would be accessible to the public, so printing sugar was that." The Von Hasselns began working on a combination of SCI-Arc machinery and printers they built themselves. The initial ambition to 3D-print the entire cake was scaled-back to 3D printing just a sparkling cake topper made only from sugar, a process that Liz likened to a micro architectural challenge. As with any material, working with sugar presented inherent propensities and limitations. However, Liz said the process of working with food had its own distinct challenges. "Because it's a food object, we've found it becomes important to consider those inherent characteristics," Liz said. "People have expectations about what food looks, tastes, and feels like, and its really important to hit those notes, otherwise you have a cool design that might not look like dessert." Once the designers embraced the inherent qualities of the material, they developed a proprietary 3D-printing process capable of fusing sugar crystals together without deforming or discoloring them. The finished product is as white and sparkling as a sugar cube. Though they missed the birthday by a long shot, the end result spelled their friend's name in a cursive scrawl made entirely from sugar. Sugar Lab, the Von Hasseln's company, has yet to build an entire town out of sugar like the utopian village brought to life by Richard Brautigan in his novel In Watermelon Sugar, but the couple has received hundreds of inquiries from around the world. They are also excited about the role of the designer in the 3D printing revolution. "We think what will move the field forward in the future is not solely additional technological enhancement, but how artists, architects, and designers utilize those capabilities," Liz said. "A 3D printer is a tool and what comes of skilled artisans wielding that tool is what will make the technology resonate with people, and make it culturally relevant."
