DSDN104 EXP2: FABRICATE DUE Tuesday December 7th at 07:00am1 30% of Course Grade Introduction “The work at each stage [of fabrication] is embodied in models, first of how something will look, then of how it will work, then of how to make it. Those models were originally tangible artifacts, then more recently became computer renderings. Now, thanks to the convergence of computation and fabrication it’s possible to convert back and forth between bits and atoms, between physical and digital representations of an object ...”2 In project one you learned to create 3D form in a virtual environment. This project explores the physical expression of 3D form through digital manufacturing. Laser cutting interprets two-dimensional CAD drawings as cutting paths. The result is typically a series of flat profiles that need to be assembled and connected in some way to create 3D form.
Design challenge Your challenge is to translate and develop your textured iteration from experiment one into a physical artefact, through the use of laser cutting. You will first need to design how your model will be divided into 2D profiles and then how the 2D pieces from the laser cutter are transformed into a 3D construction. You will be supplied one 1 millimetre-thick A4 piece of card and one 300 mm × 300 mm sheet of 2 millimetre-thick clear acrylic. The overall structure of your model must be made from these materials, but you should consider how additional materials could be used in assembly and in design details. You are prohibited from using adhesive to assemble your lasercut parts. Design development is about producing, editing and then re-producing within a set of parameters. The parameters are usually predefined but may be expected to evolve somewhat upon reflecting on each development cycle. Your task is to create, analyze, refine, and repeat.
Procedure Visit http://www.firstyeardesign.com/index.php?/courses/dsdn104 at the start of each class for the studio session plan. Visit http://dsdn104.wordpress.com/ at the start of each class for the studio session plan. 1 Deadline for submitting your laser cutting profiles: 7am 3rd December (Friday). 2 Neil Gershenfeld, The Center for Bits and Atoms, MIT
1. Begin rendering or exporting sections of your model in 3D Studio Max, and tracing/ adjusting them in Illustrator. 2. Print the 2D profiles taken from your model and cut them from card to assemble sketch models. 3. Research design precedents for examples of laser cutting and methods of assembling/ transforming 2D parts. 4. Develop your design through sketching and sketch models. Use material experiments to explore assembly techniques. 5. If needed, create an assembly in Solidworks to resolve your connection details. 6. Submit your files for laser cutting by 7am, FRIDAY 3rd December. 7. Laser cutting will take place after the submission and all parts should be ready to be collected in the next class. 8. Assemble your model, and then experiment with photography to capture the expressive potential of the form and construction details. Also, re-render your model in 3d Studio Max considering the outcomes of your photography. 9. Document the entire process on your blog, the whole time considering your graphic presentation. Deadline is 7am, TUESDAY 7th December. REMEMBER to back up your work at the start and end of each studio session.
