How is a Design Materialized?
•
Materializing a design is transformation of a virtual artifact to a physical artifact
•
In theory digital design and digital manufacturing methods will facilitate all forms of constructions
•
2D drafting will be substituted with representations in 3D for fabrication.
Ways to materialize an artifact
•
Subtractive – – –
•
Laser cutting Waterjet cutting CAD/CAM cutting
Additive – –

Error in fabrication
•
Error Correction and Redirection is found in Telecommunications – Ability to detect errors in data transmission across a noisy channel
•
What is an architectural Error
•
Patterns – Interior & Exterior Finishes
•
Error is unpredictable & costly
Cost of Error
Wall [A] = - Assembly only Wall [B] = Assembly + Measure+ Cut HouseCostTime = (nWalls x [A]) + (nWalls x [B])
Solutions
Error in fabrication is reduced by 1.
cutting or building components with precise machinery
