AirForce: Personal Fabrication of Large-Scale, Load-Bearing Animatronics Structures from a Single Tube

We present a fabrication system called AirForce that allows users to create large-scale, load-bearing animated structures from a single inflatable tube. AirForce builds on the personal fabrication of animated truss structures, based on which it replaces not only the static elements with tube, but also introduces tube-…

Mallet-Based Assembly: Enabling Load-Bearing Laser-Cut Models

Laser cutting has a long tradition of building load-bearing 3D objects based on box joints and T-joints, as these joints are naturally robust against compression and shearing. Achieving robustness against tension, however, is challenging. One presumed solution is to make all joints extremely tight, to the point where…

AirTied: Automatic Personal Fabrication of Truss Structures

We present AirTied, a device that fabricates truss structures in a fully automatic fashion. AirTied achieves this by un-rolling a 20cm-wide inflatable plastic tube and tying nodes into it. AirTied creates nodes by holding onto a segment of tube, stacking additional tube segments on top of it, tying them up, and releas…

HingeCore: Laser-Cut Foamcore for Fast Assembly

We present HingeCore, a novel type of laser-cut 3D structure made from sandwich materials, such as foamcore. The key design element behind HingeCore is what we call a finger hinge, which we produce by laser-cutting foamcore “half-way”. The primary benefit of finger hinges is that they allow for very fast assembly, as…

FoolProofJoint: Reducing Assembly Errors of Laser Cut 3D Models by Means of Custom Joint Patterns

We present FoolProofJoint, a software tool that simplifies the assembly of laser-cut 3D models and reduces the risk of erroneous assembly. FoolProofJoint achieves this by modifying finger joint patterns. Wherever possible, FoolProofJoint makes similar looking pieces fully interchangeable, thereby speeding up the user’…

AutoAssembler: Automatic Reconstruction of Laser-Cut 3D Models

Recent research showed how to import laser cut 3D models encoded in the form of 2D cutting plans into a 3D editor (assembler^3), which allows users to perform parametric manipulations on such models. In contrast to assembler^3 , which requires users to perform this process manually, we present autoAssembler, which per…

Assembler^3: 3D Reconstruction of Laser-cut Models

We present assembler^3 a software tool that allows users to perform 3D parametric manipulations on 2D laser cutting plans. Assembler^3 achieves this by semi-automatically converting 2D laser cutting plans to 3D, where users modify their models using available 3D tools (kyub), before converting them back to 2D. In our…
