Interlocking of curves

The journey of learning and experiencing Digital Fabrication began in the Fall of 2010. This class was being taught by Prof Jim Stevens. The course line up was designed by having a number of assignments though the semester starting with the ‘Gizmo’ assignment. The objective of this assignment was to get familiar with the 3D printer and the CNC machine and to understand its capabilities. There are a number of softwares available in the market today for the use of 3d printing the most common one being Rhinoceros.

A one man team Jason M. Colón began his mission of exploring the gizmo. The inspiration or the initial idea of the design came to him from a shelving unit. Jason thought of his project as a whole in terms of the installation project (our last assignment) and back tracked from there. He opted to work with ‘Autocad’ software as he was most efficient and comfortable working with it. The design started off in 2D using spline command. Once 2D planar mesh was formed, the design was taken to the next step of 3D. The planar 2D surfaces were extruded and subtracted at a few places to achieve the notches needed for assembling the design.  The flat arcs were then put together to create a shape. There are two main aspects to his design, curves and interlocking system. The idea revolves around how a prototype of a curved piece with a proper combination of interlocking system can generate numerous possibilities of creating different shapes and functions.

There are three grooves on a single piece, two smaller ones at each of the corners and one deeper one in the center, the interlocking system works by placing one piece into the other in its respective grooves. This plug and play of pieces creates various numbers of shapes and possibilities and the surface perforations add to the aesthetic value of the gizmo.
