Composite materials are on display in the undergraduate-built FIBERwave PAVILION.Carbon fiber’s unique properties would seem to make it an ideal building product. Untreated, carbon fiber cloth is flexible and easy to cut. After an epoxy cure, it is as hard as steel. But while the automobile and aerospace industries have made widespread use of the material, it has gone virtually untouched by the architectural profession. Alphonso Peluso and his undergraduate students at the IIT College of Architecture set out to change that with their FIBERwave PAVILION, a parametric, sea life-inspired installation built entirely of carbon fiber. "We want to make the studio an expert resource for people trying to get into carbon fiber in terms of architecture," said Peluso, whose students designed, funded, and built the pavilion this spring. "There’s a studio in Germany that’s in their second year of working with carbon fiber, but I don’t think anyone in the United States is working with it." Peluso’s studio began with an internal competition. Because the spring semester course followed a class dedicated to the exploration of various composite materials, many of the students were already familiar with the pros and cons of carbon fiber. "Toward the end of the first semester we started working with carbon fiber, and it wasn’t the greatest result," said Peluso. "But we knew we had to keep working with it. That played a big part in the selection of the design for the second semester." The students judged the submissions on constructability as well as aesthetics, he explained. "It was interesting to see the students as the pavilions were being presented, see their minds turning on: ‘Okay, this one is feasible—this is one we can actually build.’ Sometimes the design was a little better, but the overall project seemed less possible within the time frame." The winning design is based on a bivalve shell structure. The student who came up with the idea used parametric design software to explore tessellations of the single shell form. "What I was pushing them to do in the first semester was large surfaces that weren’t repetitive," said Peluso. "In the second semester, it was like they intuitively knew there had to be repetition of the unit." As a group, the class further developed the design in Rhino and Grasshopper. But while the students used parametric software to generate the shell pattern, in general FIBERwave PAVILION was "less about designing in the computer," said Peluso. "Most of it was fabrication based." The studio was hands-on from the beginning, when students were asked to submit a small-scale carbon fiber with their competition entries. They went back to Rhino to make the molds. "We had to make six molds," explained Peluso. "Even though it was one identical shell unit we had to produce 86 of these shells. When you make a composite unit, if you have one mold you can only make one shell per day." In the end, the students fabricated a total of 90 shells (including several extra to make up for any defects) over the course of about four weeks. "The actual assembly was pretty quick, the pavilion itself went together in less than a day," said Peluso. Laterally, bolts through CNC-drilled holes connect the shells at two points on either side. The overlapping rows of shells are secured vertically through bolted pin connections. The installation remained on the IIT campus for one month, after which the students disassembled it in just 25 minutes. The Chicago Composite Initiative, which provided crucial technical guidance during the project, has since erected FIBERwave PAVILION in one of its classrooms. The fundraising component of the project was as important as its design and fabrication elements. Peluso initially hoped that the carbon fiber industry would donate materials, but "we didn’t have as much luck as we anticipated because we hadn’t done anything before that would warrant their interest," he said. "That’s one of the goals of the pavilion itself, to create an awareness in architecture that this could be a great material to use." Peluso’s course did have help from West System Epoxy, which provided the curing resin at a discount. To fill the funding gap, the students ran a successful Kickstarter campaign, raising $6,937 from a $6,500 goal. They made incentives for the donors, including 3D-printed necklaces and earrings. "I don’t think we realized how much work was going to go into that," said Peluso. To raise additional funds, the class held bake sales on campus. For Peluso, the process of designing and building FIBERwave PAVILION proved as valuable as the finished product. "The way the students collaborated made the project a success," he said. "Sometimes in group projects you get a few drifters, and some really strong ones. But all twelve students really stepped up. This wouldn’t have happened if they hadn’t all come together as a group."
An interactive installation reconsiders the definitions of enclosure and openness.Warren Techentin Architecture’s digitally-designed La Cage Aux Folles, on display at Materials & Applications in Los Angeles through August, was inspired by a decidedly analog precedent: the yurt. “Yurts are circular,” explained Techentin, who studied the building type as part of his thesis work at Harvard’s Graduate School of Design. “That began the idea of using small-diameter rods and taking software and configuring sweeps with some special scripts that we found online.” But while the yurt’s primary function is shelter, Techentin’s open-air installation, built of 6,409 linear feet of steel pipe, is a literal and intellectual playground, its form an investigation of the dualities of inside and out, enclosure and openness. Once the architects became familiar with the scripts, which allowed them to manipulate multiple pipes simultaneously, they found it easy to generate designs. The hard part was settling on a final shape. Then an off-hand observation narrowed their focus. “Somebody made a comment about, it looks like a crazy cage,” said Techentin. “We realized, ‘Oh, there’s this cage component. What if we imagine spaces inside spaces?’ That’s where these interiorized conditions came through, kind of creating layers of inside and outside.” Technical constraints further influenced the form. “We had to jump out of the digital world and decide how this was made in reality,” said Techentin. To minimize materials costs, the architects decided to work with schedule 40 steel tube, which is available in 24-foot lengths. Returning to Rhino, they broke apart their model and rescripted it accordingly. They modified their model again after learning what radiuses their metalworking contractor could accommodate. “It was kind of a balancing act between hitting these radiuses, the 24-foot lengths, and repetition—but how do you get difference and variety,” said Techentin. Warren Techentin Architecture originally sought a digital fabricator for the project. But the quotes they received were too high, and they could not locate a manufacturer able to work with pipes longer than six feet. They contacted Paramount Roll and Forming, who rolled and bent the tubes by hand for one-tenth of what digital fabrication would have cost. “It wasn’t what we wanted, but in the end we wanted to see the project through,” said Techentin. Paramount sent the shaped steel to Ramirez Ironworks, where volunteers interested in metalworking helped assemble the structure. The design and fabrication team then disassembled it, painted the components, and transported them for reassembly on the site, a small courtyard in the Silver Lake neighborhood. La Cage Aux Folles invites active exploration. “My work draws great influence [from] architecture as something that you interface with, interact with—that envelops you, becomes part of an environment you participate with,” said Techentin, who overheard someone at the opening call his structure “a constructivist playground.” “We fully intended people walking around in there, lying down,” he said. “The surprise factor were the number of people who feel inspired to climb to the second and, more ambitiously, the third cages. We’re not encouraging it, but people do it.”
“A continuous thread will move across new and existing elements in the garden to filter the natural light and create new passages and spaces to gather and reflect. At the same time, the installation’s architecture is being broken apart. Its walls are transparent.”LAND Studio is also engaged in a makeover of Cleveland's downtown Public Square and a rails-to-trails project along Cleveland's old RTA Red Line.

A room-filling parametric design makes its way from the classroom to Austin's famous music festival.When Kory Bieg and his students at The University of Texas at Austin School of Architecture began working on Caret 6, they had no idea that it would wind up at this year’s South by Southwest (SXSW) music and arts festival. But the rippling, room-filling installation soon took on a life of its own. Within months, Bieg’s undergraduates—who had little previous exposure to digital design—had designed and fabricated Caret 6, and assembled and disassembled it twice, first at the TEX-FAB SKIN: Digital Assemblies Symposium in February, and then at Austin’s most famous annual gathering in March. Caret 6 developed out of a research studio taught by Bieg, who is also associate director of the regional digital fabrication and parametric design network TEX-FAB. Selected to chair TEX-FAB’s annual design competition, Bieg knew that he would soon face a problem: how to display the winning entry in a gallery much larger than it. He put his students to work on a solution. “The idea was to create a kind of counterpoint to the winning entry. [We] needed to fill space,” said Bieg. At the same time, the studio would teach the fundamentals of digital fabrication. “It was really just an experimental exploration of what these tools could produce,” he said. Caret 6’s white and grey diamond-shaped cells cascade from a central catenary vault with three column bases. Two secondary vaults project from either side. The front face of the structure flows down to the floor. “The idea is, we didn’t actually know who the winner [of TEX-FAB: SKIN] would be,” said Bieg. “We wanted to design a ground surface that was modular so that we could replace some of the cells with bases for their models.” The 17 students enrolled in Bieg’s course first created individual study models of aggregations and weavings amenable to digital fabrication. In an internal competition, they narrowed the field to three. Bieg broke the studio into teams, each of which experimented with creating volumetric versions of the designs. In a departure from typical parametric installations, Bieg and his students decided to stay away from patterns that gradually expand and contrast. “Our interest was not [in] doing subtlety, but local variations that are quite abrupt, like going from a large cell to a small cell,” said Bieg. “So part of that was a result of the way we structured it. Instead of aggregating cells, we designed a series of ribs.” The primary ribs form the vaults’ seams, while the secondary and tertiary ribs divide the structure into asymmetrical pockets. Halfway through the semester, Bieg called Alpolic Materials, whose Aluminum Composite Material (ACM)—a thin polyethylene core sandwiched between two sheets of aluminum—he had worked with on an earlier project. Alpolic agreed to donate supplies for Caret 6, “so we refined the design according to the material we had,” said Bieg. He also drafted students from UT engineering to calibrate the structure’s thickness, scale, and cantilever distances. “It kind of just evolved from these different processes coming in,” said Bieg. Back in the studio, Bieg’s students used 3ds Max for form studies and Kangaroo, a Grasshopper plug-in, to fit the tessellated diamond pattern to the vaults. They also used Grasshopper to develop an assembly system of binder rings, bolts, and o-rings. Bieg and his team fabricated the installation using UT’s CNC mill. They cut the vault pieces out of Alpolic ACM. The elements closest to the floor are polypropylene, while the intermediary pieces are high-density polyethylene. The students assembled and disassembled Caret 6 manually. At first, they tried working with a QR-code system, scanning each component to determine its location. When this took too long, they projected a digital model of the form on a screen, then called out each piece by number. For SXSW, where they had only six hours for assembly, they subdivided the structure into sections that could be quickly recombined on site. Caret 6 travels to Houston in September, where it will rejoin the entire TEX-FAB: SKIN show. But while the installation has already moved beyond its original context, Bieg insists that it remains rooted in the SKIN competition brief, which focused on building envelopes leveraging metal fabrication systems. “[Caret 6 is] not really a program per se, but more of an experiment about the same concepts that were part of the exhibits at TEX-FAB,” he said.
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.”
