Marty is the result of what turned out to be a 3 week summer intensive course in robotic fabrication using an industrial robot to 3d print. The end result is a dining chair made from post consumer recycled PETG that uses 50% less plastic than its market counterparts.
Learning to use grasshopper was like learning a new language but soon enough I came to terms with the software. The attached images layout the programming for the chair itself, assurances to ensure manufacturing success such as a brim and how the object itself sits in relation to the machine so it can print.
Triangulation in the back half of the chair disperses the weight evenly to increase the load bearing capacity, this feaures also follows the same contours as other parts of the chair creating a dynamic component under the seat. Air pockets from moist plastic create a sparkle effect that plays well when exposed to direct light. The layer lines add to the refracting of light and create a dynamic surface on the chair.
Unlike market competitors only the back half of the chair is double walled for strength rather than the whole object which reduces the amount of plastic used by up to 40%.
