A group of students of the Bartlett School of Architecture at the University College London called CurVoxels have turn it intod a new 3D printing technique that allows for them to 3D print rigorous curved, three-dimensional structures. The team utilized the new process to turn it into a set of intricately printed filigree cantilever chairs and a filigree spiral staircase. The Spatial Curves project was accomplished by the team at Bartlett’s Research Cluster 4, where the custom-made 3D printing device was utilized to turn it into the team’s own create of the iconic Panton chair. The chair was made in 1906 by Danish createer Verner Panton and is the world’s initially molded plastic chair.

Panton regularly remade his famous chair, and other createers may routinely apply their own create aesthetic to turn it into their own creates of the classically shaped cantilever chair. For the Spatial Curves project, not just did the CurVoxels team select to create their own create of the Panton chair, but they wanted to completely reinterpret how it was made. The goal was to see if their new 3D printing process may be applied to a previously existing 3D create. After that successfully fabricating their own chairs, the team presented their project at Bartlett’s B-Pro Show 2015 graduation exhibition held in London and again at the Synthetic 2015 Exhibition in Le Mans, France.

3dp_filigreechairs_trioThe process of constructing the chair starts when the 3D version is voxelized, that is a process of breaking down an object into tiny “volumetric pixels.” The individual voxels are converted into a basic spatial curve, that is capable of adopting different types of orientations as well as generating different types of patterns throughout the chair. The dimensions of equite voxel changes depending on the amount of mass that the chair needs to accommodate and the 3D printing material is distributed in different types of densities. If the voxels are quite tiny, the spatial curve fundamentally becomes a easy line, while sizeabler voxels can become different types of patterns like the filagree create of the final chairs. The initially simulations conducted twelve different types of create options that tested toolpath continuity, any resulting patterns, printability and the final object final density.


The 3D printing device that was turn it intod by the team included a custom nozzle that is capable of extruding four- to six-millimeter-thick strings of the plastic filament that may completely solidify in the air. The robot 3D printing device just printed in three-dimensional space pretty than along a two-dimensional additive layering process. An algorithmic technique was turn it intod to control the amount of material that is extruded, as well as the specific path that the printing device may take in order to print the chair in a continuous extrusion. This allowed the team to 3D print the chair completely uninterrupted, that was faster, utilized less material and generated a additional solid piece of furniture while maintaining a high degree of more detail. The createers in addition turn it intod an app that allowed them to diversify the pattern and increase density while it was being 3D printed in order to improve structural integrity.


“CurVoxels has turn it intod an experimental digital technique for creating rigorous curvilinear space frame structure such as columns, chairs, staircase and pavilion, based on Mereology with one easy component by via combinatorial process and seamless sizeable scale spatial 3D printing. Basically, Spatial Curves integrated the areas of digital create process with digital fabrication processs and has the objective of optimising the future of computational create in architecture by overcoming the limitations of fabrication inherent to previous digital architectural create,” said the CurVoxels team of their project.

Here is a few video of the filagree chairs being 3D printed:

Team CurVoxels is Hyunchul Kwon, Amreen Kaleel and Xiaolin Li, and their project tutors were Manuel Jiménez García and Gilles Retsin.

The goal of their project was to create a new process of via high end robotics to create sizeable-scale 3D printed objects. They chose the Panton chairs as a proof of concept, but the fabrication technique is applicable to virtually any type of furnishings, structural component or architectural showcase.
