The goal of the Symposium on Computational Fabrication has always been to bring together -- from all areas of science, design, and engineering -- people who use computers to make things. Our technical papers program this year does a good job of capturing that vision. From a strong field of 18 submissions, our area chairs and external reviewers selected 9 papers which demonstrated technical rigor, clear presentation, and novel results.
In these proceedings, you will find contributions from architecture, human-computer interaction, graphics, robotics, and materials science; all tied together by the same thread: the idea that we can use algorithms to multiply, enable, and expand the capabilities of our physical tools. From cement and tree branches to lasers and projectors, these papers demonstrate that computational fabrication is relevant and powerful in an ever-growing array of contexts and situations.

Human-in-the-loop fabrication of 3D surfaces with natural tree branches
We propose a design and fabrication system leveraging the diverse shapes of natural wood. With our system, precise geometries are fabricated from non-standardized, naturally curved branches. In this way, low-valued tree branches are up-cycled to a ...
Exploring mechanical meta-material structures through personalised shoe sole design
Mechanical meta-material structures (MMS) are designed structures with mechanical properties not found in ordinary materials. MMS can now be created far more easily using digital manufacturing. We explore how different MMS can be combined, through the ...
Automated reconstruction of smoothly joining 3D printed restorations to fix broken objects
In this work, we provide an approach to automatically reconstruct a 3D printed restoration piece for a broken object from 3D scanned meshes of the broken object and an original counterpart. Our approach provides two contributions to reconstruct a ...
Rough carving of 3D models with spatial augmented reality
Carving is a subtractive process where we get the shape by removing materials. While most people can get roughly the right intended shape, it is usually challenging not to over-cut the model. We propose a method that helps an unskilled user to carve a ...
Echidna: mixed-domain computational implementation via decision trees
Custom mechatronic devices offer personalized functionality, but also come with many non-functional requirements that are unfamiliar to those inexperienced with electronics such as current draw and servo power. The Echidna prototype system enables non-...

We present the first algorithm for designing volumetric Michell Trusses. Our method uses a parametrization-based approach to generate trusses made of structural elements aligned with the primary direction of an object's stress field. Such trusses ...
A method to evaluate the formability and fluidity of concrete based materials for 3D printing
Use of 3D printers for construction brings a new possibility of creating walls with shapes that were not possible with conventional construction methods. However, existing construction materials can not be used for 3D printing as they are, and the ...

Non-standard stairs have an important role in architecture, but their complex details and three-dimensionality pose significant fabrication challenges. One of the preferred materials for custom stairs is concrete, which can be cast in complex shapes, ...
Computational laser forming origami of convex surfaces
Laser forming is a fabrication method that uses laser to fold sheets into 3D structures. To overcome the limitations in the traditional practice that relies on tedious manual design, this paper advances laser forming by developing computational methods ...
