Digital Modeling and Fabrication is a process that joins architecture with the construction industry through the use of 3D modeling software and CNC machines. These tools allow designers to produce digital materiality, which is something greater than an image on screen, and actually tests the accuracy of the software and computer lines. Computer milling and fabrication integrate the computer assisted designs with that of the construction industry. In this process, the sequence of operations becomes the critical characteristic in procedure. Architects can propose complex surfaces, where the properties of materials should push the design.

Some of the modeling software programs include Rhinoceros 3D, 3D studio max and SketchUp.

[edit] Machines for Fabrication

[edit] CNC router

CNC stands for computer numerical control. Through a computer controller, G-codes are read which represent specific CNC functions in alphanumeric format. The g-codes drive a machine tool, a powered mechanical device typically used to fabricate components. CNC machines are classified according to the number of axes that they possess. CNC machines are specifically successful in milling materials such as plywood, foam board, and steel at a fast speed. CNC machine beds are typically large enough to allow 4’ x 8’ sheets of ¾” thick plywood to be cut.

[edit] Laser Cutter

The laser cutter is a machine that uses a laser to cut materials such as chip board, matte board, thin sheets of wood, and plexy up to 3/8" thickness. AutoCad is used in the production of lines on a grid, which would be sent to the laser cutter as a .dwg file. Lines can either cut through the material or score it depending on the color of the line drawn. Lines drawn in white will be cut and lines in red will score the material in the cutting bed. Objects cut out of materials can be used in the fabrication of physical models, which will only require the piecing together of the parts.

[edit] Z plotter

The Z plotter is one of the newest technology tools available to architects and designers. The machine allows a "Z plot" model to be made in Rhinoceros as a 3D object; in the Z direction. The bed of the machine is an 8" x 10" x 10" high box, which will add several layers of a powder resin through a series of fills. Once a Z plot is finished, the excess powder must be removed away from the model. The model at this point can be fragile depending on the thickness of some of its members. For added stability, the z plot model should be placed in a wax based machine for about 20 minutes, which will harden the structure.
