Digital modeling and fabrication is a process that joins design with the construction / production through the use of 3D modeling software and

additive and subtractive manufacturing processes.

Numerical control is the automation of machine tools that are operated by precisely programmed commands encoded on a storage medium, as

opposed to controlled manually via hand wheels or levers, or mechanically automated via cams alone.

A fab lab (fabrication laboratory) is a small-scale workshop offering (personal) digital fabrication. A fab lab is generally equipped with an array of flexible computer controlled

tools that cover several different length scales and various materials, with the aim to make "almost anything". This includes technology-enabled products generally

perceived as limited to mass production.

This course provides a hands-on introduction to the resources for designing and fabricating smart systems, including CAD/CAM/CAE; NC machining, 3-D printing, injection molding, laser cutting; PCB layout and fabrication; sensors and actuators; analog instrumentation; embedded digital processing; wired and wireless communications. This course also puts

emphasis on learning how to use the tools as well as understand how they work.

“Digital fabrication” refers to processes that use the computer-controlled tools that are the descendants of MIT’s 1952 numerically controlled mill. But the

“digital” part of those tools resides in the controlling computer; the materials themselves are analog. A deeper meaning of “digital fabrication” is

manufacturing processes in which the materials themselves are digital.

Digital Fabrication: Programable MatterHod Lipson @ Cornell

… what I consider to be two “grand challenges” of engineering: (a) Can we design machines that can design other machines, and (b) Can we make machines that can make other machines. Both of these questions lie at the crux of understanding the engineering

process itself, and progress on these fronts can offer huge leverage in our ability to design, make and maintain increasingly complex systems in the future. Biological life has answered

these challenges in ways that dwarf the best teams of human engineers; I therefore use primarily biologically-inspired approaches, as they bring new ideas to engineering and new

engineering insight into biology.

2D Design - from Principles of Form and Design by Wong Composition (armatures, cropping and framing) - from 2D Composition by Roberts

Please Complete by Next Monday 9am:

• Composition in 2D: Choose three objects of your preference and build their outlines. Present at least three compositions in Rhino for the arrangement of these objects in 2D space, and briefly articulate your design decisions. Submit one page with a screenshot of the objects and a single paragraph of text.

• Final Project: Using 2D (manual!) sketching, draw a sketch for dual-agents of your final project. Submit the drawing.

• Spline Model in 3D: Choose 3D product of your preference (shoe; clock; glasses; car; stereo system) and model it with splines in 3D. Use the Osnap tool and add dimensions on the drawing. Work with layers and explore the different display modes. Submit the CAD file.
