Fabrication (PhD Topic)

Low-Fab (low-fidelity fabrication)

The concept of low-fi fabrication allows for fast iterative prototyping. In contrast to the traditional workflow, in which the 3D model is always fabricated as a slow hi-fidelity version, low-fi fabrication fabricates all intermediate versions as fast low-fidelity previews. Only at the end when the design is finished, the complete 3D model is printed. Low-fi fabrication can be implemented in different ways: With our project faBrickation we show one implementation that combines construction kit building blocks, such as Lego, and 3D printing. [...]

Platener: Low-Fidelity Fabrication of 3D Objects
by Substituting 3D Print with Laser-Cut Plates

Dustin Beyer, Serafima Gurevich, Stefanie Mueller, Hsiang-Ting Chen, and Patrick Baudisch
In Proceedings of CHI '15 (Paper, to appear). [BEST PAPER NOMINEE]
Platener is a system that allows quickly fabricating intermediate design iterations of 3D models, a process also known as low-fidelity fabrication. Platener achieves its speed-up by extracting straight and curved plates from the 3D model and substituting them with laser cut parts. [...]

Scotty: Relocating Physical Objects Across Distances Using Destructive Scanning, Encryption, and 3D Printing

Stefanie Mueller, Martin Fritzsche, Jan Kossmann, Maximilian Schneider,
Jonathan Striebel, and Patrick Baudisch
In Proceedings of TEI '15 (Paper).
We present a simple self-contained appliance that allows relocating inanimate physical objects across distance. Each unit consists of an off-the-shelf 3D printer that we have extended with a 3-axis milling machine, a camera, and a microcontroller for encryption/decryption and transmission. [...]

Fast 3D Printed Previews

Stefanie Mueller, Sangha Im, Serafima Gurevich, Alexander Teibrich, Lisa Pfisterer,
François Guimbretière, and Patrick Baudisch
In Proceedings of UIST '14 (Paper).
WirePrint is a low-fi fabrication technique that prints 3D models as wireframe previews. By extruding filament directly into 3D space instead of printing layer-wise, we achieve a speed-up of up to 10x compared to traditional 3D printing. [...]

faBrickation: Fast 3D printing of Functional Objects by Integrating Construction Kit Building Blocks

Stefanie Mueller, Tobias Mohr, Kerstin Guenther,
Johannes Frohnhofen, and Patrick Baudisch
In Proceedings of CHI '14 (Paper). [BEST PAPER NOMINEE]
faBrickation a new approach to rapid prototyping of functional objects, such as the body of a head-mounted display. The key idea is to save 3D printing time by automatically substituting sub-volumes with standard building blocks — in our case Lego bricks [...]

Laser-Cutting 3D Objects

Stefanie Mueller, Bastian Kruck, and Patrick Baudisch
In Proceedings of CHI '13 (Paper). [BEST PAPER AWARD]
We present LaserOrigami, a rapid prototyping system that produces 3D objects using a laser cutter. LaserOrigami is substantially faster than traditional 3D fabrication techniques such as 3D printing and unlike traditional laser cutting the resulting 3D objects require no manual assembly [...]

Interactive Construction:
Interactive Fabrication of Functional Mechanical Devices

Stefanie Mueller, Pedro Lopes, and Patrick Baudisch
In Proceedings of UIST '12 (Paper).
constructable is an interactive drafting table that produces precise physical output in every step. Users interact by drafting directly on the workpiece using a hand-held laser pointer. The system tracks the pointer, beautifies its path, and implements its effect by cutting the workpiece using a fast high-powered laser cutter. [...]

CapStones and ZebraWidgets: Sensing Stacks of Building Blocks, Dials and Sliders on Capacitive Touch Screens

Liwei Chan, Stefanie Mueller, Anne Roudaut, and Patrick Baudisch
In Proceedings of CHI '12, pp. 2189-2192 (Note).
Recent research proposes augmenting capacitive touch pads with tangible objects, enabling a new generation of mobile applications enhanced with tangible objects, such as game pieces and tangible controllers. In this paper, we extend the concept to capacitive tangibles consisting of multiple parts, such as stackable gaming pieces and tangible widgets with moving parts. [...]
