Introduction

The Digital Fabrication Introductory course focuses on utilizing production techniques by learning the use of three different machines: CNC Milling, Laser Cutting and 3D Printing. The focus of the course was to fabricate different modular recursive geometries with different fabrication techniques along with the learning-by-doing manifesto. Through this course we learned the safety protocols for using each machine, and how to set up each machine for fabrication.

LAZER PRINTING

In the laser cutting fabrication method, we aimed to create an abstract tetrahedron in an exploded look by combining 4, 6x6x6cm triangles with interlocking technique. In order to keep the shape of these modules and the tension between them, we decided to use three different types of press fit joint. Moreover, we used 2 different colored acrylics that are 3mm thickness. One of them is in transparent the other one is fluorescent colored.

Material: Acrylic 3mm transparent/ fluorescent
Technique: Interlocking
Joint type: Press Fit Joint
Machine: Epilog 75(p59)

// Singular Geometry

// Final Recursive Geometry

// Digital Recursive Growth

3D PRINTING

We created a recursive geometry with nodal joinery systems. Six node variations were designed and fabricated. Between the joints, we worked with 2mm rods. One of the most important part of this fabrication is to focus on how to optimize the model in the software to reduce the time and material usage.
