The Book of Joints


As a collection of constructive components, the "Book of Joints"

presents a panel of unique pieces of digital joinery. Each one of them had been carefully design by the collective In-Dialog to serve a very specific purpose, as part of the projects they developed over the past few years. The majority are crafted to be 3D printed, but for most of the projects, the making process involves a wider range of manufacturing techniques, from very analog and hands on, to digital fabrication only.

#1 I CAN NO LONGER HEAR THE NOISE OF CRICKETS tool : 3D PRINTER material : PLA, electronic components Sound reactive installation made of 3D printed parts. The digital crickets are programmed to communicate with each other via sound. When a sound triggers one of the modules, a chain effect

takes space and the sworn starts to communicate with each other. A microphone and a LED are attached to the parabola which acts as a sound reflector. The surrounding sound is processed by an Arduino nano enclosed in the case and a buzzer is embedded in the cone, which spiral creases help to diffuse the sound.

#2 XY DRAWBOT tool : 3D PRINTER materials : PLA Those custom 3D printed feet are bolted in the X aluminium profiles of the XY Drawbot. They can also be attached to a board, to secure the machine in place and avoid any movement of the

frame. They are designed for stability in order to produce a better accuracy in the drawings plotted. They are laid flat on the printer bed for better rigidity, so the layers of the prints are vertical when the foot are attached to the frame.

#3 POLARGRAPH DRAWBOT tool : 3D PRINTER, Laser cut material : PLA, electronic components, plywood This drawing robot is driven by 2 stepper motors, an Arduino Uno and a G-Shield. The modular design of the machine allows to be scaled up in order to produce gigantic drawings, by only

extending the length of the timing belt. In order to keep a good drawing precision, the timing belt need to be tensed: some long m16 hex nuts and bolts are attached to the weights holder. Finally, all the pulleys have bearings embedded in order to minimize the friction.

#4 ARCADE GAME TABLE tool : Laser cutter material : 8mm Plywood, transparent PMMA, electronic components, screen, Mac mini This table was commissioned by the City of Creteil to display a video-game developed by Codin Segal. An Ikea coffee table was hacked

and cut to become the support for the hardware. The laser cut wooden frame allows to create a secured enclosure for the computer. It also serves as stand for the transparent cover where the joystick and buttons to control the game are attached.

#5 ULTIMAKER EXTENDED tool : Laser cutter material : 5 & 10mm plywood This custom frame for the Ultimaker 3D printer allows to hack the UMO kit in order to extend the printing height from 20 to 50cm. The use of two different thickness of plywood allows to

reduce the weight of the machine while assuring a good rigidity. Thanks to the big openings on the front and side, the printing bed is easy to reach. The parts are bolted together using the interlocking system borrowed from the Ultimaker original design. Last but not least, the great Rick Sanchez was engraved on the back for inspiration purpose, we used to have a plumbus on it.

#6 MAGNETIC MOTION tool : Laser Cutter material : 3mm MDF, magnets, bearings This device plays with magnets' polarity in order to create a chain effect of touchless movements, induced by a single electromagnet. As the system allow to contain the magnets in both horizontal

and vertical positions, a play of attraction and repulsion can happen. The laser cut MDF slices holds the magnets in place and host a bearing in their centre. The little tower fits in the bearing and have a T-slot to clamp the head of the bold that maintain the system on the circular plate.

#7 MAGNETIC FIELD tool : 3D PRINTER material : PLA, electronic components This machine allows to move some magnets up and down, bringing them closer or further to the dish containing iron powder. The game of attraction and repulsion created by the magnetic

fields moves the iron powder, thus creating visual patterns. The vertical cuts in the legs act as rail for the magnet holder. It is attached to a system of ropes and springs, that can be activated by hand or with motors attached on the smaller gear.

clamp and hold firmly to the sticks. To ensure the strength of the connexions, the 3D printed joints were then tight with rope, and covered with resin. Couple of iterations were produced before this final set, and each piece were carefully, and brutally tested for their solidity and durability.

with a hands-on approach. The boxes are designed to protect the machines while being easily transportable. Their parts are bolted together thanks to the T-shape interlocking system. The cuts on the side of the boxes allow to make their weight lighter. Handles, hinges and locks are added for better practicality.

#10 TOPOLOGICAL OPTIMIZATION WOOD JOINT tool : 3D PRINTER materiel : PLA, timber, plank This series of timber and plank systems explore a design process in three steps using typology optimization. It reduces the material volume, revealing the flow of forces in the object and gives guidelines for the 3D modelisation of the final piece.

plank 4

Using Fusion 360° to run simulations of the physical properties of each component, a rough geometry (a) is imported. The material parameters and forces are applied to the mesh that gradually carves out where the material is not needed (b). The final mesh (c) is modeled on top of the brute mesh to keep a precise aesthetic.

a single element that could be positions at any angle allowed to do direct adjustments on site. The rotation part that is on the side of the board is detached from its base in order not to struggle during the assembly. This system can be easily reused in another context by simply adapting the base.

In-Dialog is exploring a work methodology that uses creatively machines and algorithms to research the manner in which we interact and perceive our environment. In-Dialog’s work is based on a transdisciplinary approach in experimenting with digital technologies. Calin Segal, Tiffany Attali and Joaquin Villalba founded it in 2014 with the vision of creating devices, installation and performances that explore human and machine interactions. For the past two years our collective has been driven by one question : How can we encourage social interaction ? When we look at how technology is being used today it seems that more and more creative power is dedicated to develop and promote a lifestyle where human interaction is limited and most of our needs can be satisfied by devices or apps. We live in a world that is deprived of physical contact, inclosed on itself and imprisoned in our own bubble; we yearn for the company of each other but forgot how to express it. Even if this statement is overdramatizing reality we can't ignore certain behavior patterns in our society. Most of consumer oriented development in technology today is dedicated to create social platforms that outright social moments by offering distractions. More and more of our daily experiences require minimum human interaction and we have at our disposal millions of line of code written with the sole purpose of keeping ourselves busy. We are now focussing on developing installations where the center piece is the ability to encourage interaction between individuals while creating a collective experience. We are creating installations that can become device to break throug social anxiety and encourage physical interaction, objects that are conversation starters giving a common denominator that will help kickstart a discussion. For our design thinking, we aim at helping an individual communicate his inner state to the others via digital devices. We see those devices as training wheels, they are meant to lighten the effort of exchanging feelings and emotions between each other. We see it as an empathy enhancer where subtle behavior traits are amplified in order to communicate the inner state of an individual.
