In a compelling display of design innovation, the Danish studio Oberdoerfer & Krebs has pioneered a novel method for crafting furniture, blending advanced 3D printing technology with the tactile artistry of hand manipulation. Their recent showcase in Copenhagen, featuring the "Bend Chair" and "Bend Stool," illustrates a paradigm shift in how digitally fabricated objects can achieve unique and fluid forms.
Copenhagen's Design Event Highlights Pioneering Furniture Creation
During the lively 3daysofdesign festival in Copenhagen, a vibrant platform for emerging designers, the creative duo Jasper Krebs and Bruno Oberdoerfer of Oberdoerfer & Krebs captivated attendees at Ukurant. They introduced a groundbreaking line of seating that transcends the conventional boundaries of large-scale 3D extrusion. Rather than producing finished articles directly from the machine, their process involves an intermediate stage where heat and manual bending are applied post-printing, culminating in a distinctive blend of programmed structure and organic shape.
Their signature pieces, the Bend Chair and Bend Stool, embark on their journey with the familiar framework of large-scale extrusion. However, they diverge from the rigid, fixed profiles typically associated with this manufacturing technique. Once printed, these creations undergo a reheating phase, allowing for specific sections to become pliable. Skilled hands then meticulously bend and sculpt the softened material into its ultimate form. This interplay between predefined digital geometry and human dexterity imbues each item with a singular tension, where the printer establishes the fundamental structure, but the human touch completes its expressive contours.
The studio's philosophy centers on leveraging large-scale 3D printing as a flexible process, open to interruption, redirection, and subsequent shaping after the initial machine-driven phase concludes. This approach moves beyond viewing a print as a final product straight from the nozzle. Instead, their designs intentionally integrate moments where factors such as heat, gravity, precise timing, and human touch become integral to the crafting journey. The digital blueprint, or toolpath, is not merely a technical instruction set but also a guide for future physical manipulations.
Further demonstrating their innovative spirit, Oberdoerfer & Krebs utilized expandable colorFabb LW-PLA. This material allows for the foaming of middle layers during printing, effectively reducing material consumption while subtly altering the object's characteristics without necessitating a change in filament. Depending on temperature and printing strategy, the same material can be rendered lighter, softer, or more rigid, enabling design exploration through various material states rather than through a multitude of different materials. This inventive application of material properties was first explored by Jasper Krebs during his third-semester project at the Royal Danish Academy in Copenhagen, laying the groundwork for broader research into formal languages within 3D printing.
Their experimental ventures also include "UpsideDown," a playful take on control within 3D printing. This project features a wall-mounted rack created by deliberately guiding the 3D printer off its intended path mid-print, extruding plastic into open air. The material then sags under its own weight before the machine resumes. Once cooled and inverted, these unexpected sagging loops transform into functional hooks. This work cleverly bridges the gap between precise digital control and serendipitous forms typically avoided in additive manufacturing, turning a printer's 'detour' into a practical and aesthetically intriguing component.
In another exploration, "Human Layers," presented at the Biennale for Craft & Design, the duo ventured into vessel-making. This project maintains their consistent interest in process-driven design, drawing inspiration from ikat, a textile dyeing technique where patterns are pre-planned in the threads before weaving. This concept is translated into pellet-extrusion printing, where color emerges through calculated flow, timing, and repeated human intervention. By developing a method for controlling multiple colors in pellet-based 3D printing, they meticulously calculate the precise appearance of each hue across the surface. PLA pellets, tinted with liquid masterbatch, are weighed and introduced at specific junctures during the printing process. As each batch passes through the nozzle and integrates into the layer below, it leaves a tangible record of its journey, transforming what appears as ornament into a choreographic dance of materials.
The collective body of work—including the Bend Chair, Bend Stool, UpsideDown, and Human Layers—underscores Oberdoerfer & Krebs' vision of large-scale 3D printing not as a rigidly closed system, but as a dynamic field of nuanced decisions. By integrating post-print bending, deliberate off-path extrusion, foamed materials, and precisely timed color transitions, they significantly broaden the expressive potential of 3D-printed objects. Their projects compellingly argue for a future of digital fabrication where the essence of traditional craft not only endures but flourishes within the mechanical realm, particularly in those flexible junctures where the manufacturing process can still be guided and transformed.
This innovative approach from Oberdoerfer & Krebs inspires a re-evaluation of the relationship between human craftsmanship and automated production. It challenges the conventional view that digital fabrication must lead to uniform, perfectly replicated objects. Instead, it demonstrates the profound potential for hybrid processes to create furniture that is not only functional but also imbued with a unique, handmade character. This blending of precision technology with artistic intuition opens up exciting new avenues for designers to explore, where the 'imperfections' or deliberate interventions can become the very hallmarks of distinctiveness and value.
