Ludwig Wilhelm Wall
IT-Systems Engineering Master of Science
graduated from
Hasso Plattner Institute, Germany.

I am interested in personal fabrication and how it will change the world, when computing and material come together. Throughout my masters at Hasso Plattner Institute, I contributed to six research projects (two to appear) at the chair of Patrick Baudisch on personal fabrication, all of which were published as full paper publications at CHI and UIST. I spent the past year contributing to a personal fabrication spin-out out of this group (kyub) and am looking to continue in research and start a PhD.

Digital Mechanical Metamaterials:
Integrating simple computation into 3D printed
objects’ cell structure

Exploring how to embody mechanical computation into 3D printed objects, i.e., without electronic sensors, actuators, or controllers typically used for this purpose.
A key benefit of this approach is that the resulting objects can be 3D printed in one piece and thus do not require assembly. [...]

[BEST PAPER HONORABLE MENTION AWARD]
Such metamaterial mechanisms consist of a single block of material the cells of which play together in a well-defined way in order to achieve macroscopic movement. Our metamaterial door latch, for example, transforms the rotary movement of its handle into a linear motion of the latch. [...]

LaserStacker:
Fabricating 3D Objects by Laser Cutting and Welding

The key idea of LaserStacking is to use the laser cutter to not only cut but also to weld. Users place not one acrylic sheet, but a stack of acrylic sheets into their cutter. In a single process, LaserStacker cuts each individual layer to shape (through all layers above it), welds layers by melting material at their interface, and heals undesired cuts in higher layers. When users take out the object from the laser cutter, it is already assembled. [...]

Master Thesis at Hasso Plattner Institute

Design and Synthesis of Digital Mechanical Metamaterials

This master thesis presents a software system that allows users to design and fabricate simple interactive objects with integrated digital mechanical metamaterials. Its main component is a custom voxel editor for modeling 3D objects, routing signals through them, and verifying the correctness of "circuitry" by simulating the signal flow. Additionally, the editor automatically synthesizes and minimizes cell patterns that implement user-defined logic functions, supports layouting through automatic pathfinding as well as free-form path drawing and exports 3D-printable files.
