• Complete and bring to class your perfected re-fabrication of the final laser-cutter project; all students are required to rebuild one of their two projects, based on the feedback given in class last week
• Create a posting on this blog with final Rhino files for the above project, as well as images of your fabricated object; photographs must be taken on a solid color back-ground (see photo facilities in Maggy Morrison or contact our graduate assistant Luke)
• Review and master all Rhino commands from this post and this post
• Complete the assigned point-cloud->3d model; prepare two versions: 1) actual scale, 2) miniature (L + W + H < 4 inches);
• Process the miniature version of your model for 3d printing on the FDM ABS printer (create mesh, check mesh, export stl, run through Catalyst)
• Prepare a preliminary sketch of your next 3d printing project; be prepared to present your idea to the class for feedback/critique. Help us get a clear sense of your idea by preparing rough drawings in Rhino, sketches on paper, images of works of reference, accompanying text.  This project will be due on Feb. 22, 2012.

Terry the Woodshop Tech showed me this and I thought share it here too. Its a free program where you take multiple photos of an object, send it to some server(cloud?), and you get back a 3-d model of it for use in CAD programs. I’m really not sure how it works and haven’t tried it yet, but it doesn’t sound too hokey.

Reminder to meet at 8.30am sharp at the dFAB facilities in M Morrison for Zach Ali’s demonstrations of usage of the 3D printers.

• give some thought to your eventual 3d printing project (due in 3 weeks)
• choose a small object to model; make an attempt to relate the choice of this new object to the eventual needs and goals of your 3d printing project
• put 20-50 visible/colored points (colored stickers work well) on important structural points/features of your object (corners, edges, peaks, troughs)
• photograph the object from at 5 perspectives (Top, Left+Right, Front+Back); use ~50mm lens to minimize distortion
• import these images into Rhino as backgrounds and begin modeling the object in three dimensions first with lines and curves, and then with surfaces.

• Choose one of the two objects you fabricated for the last assignment, make it again and better.
• Use the CFA facilities to photo document then fabricated object from multiple perspectives, on a solid color back ground, with proper lighting; please contact our Graduate Assistant Luke (contacts in the syllabus) if you need help/guidance in the process

Assignment #1

I was imagining a future in which laser cutting is essential to all food production. Similar to how fast food is entirely processed and distant from what we know of “beef” or traditional food, I was thinking about a future in which all food needs to be shaped in from where it is coming from. In this case it would be beef cutout.

Assignment 2: generated design

This is a design entirely made out of squares. I began with a square and multiplied it along a curve. From that point my rules entailed many reflections, rotations and scaling.

Assignment #3: organic boxs

From Amazon:

Where does our current obsession for interactivity stem from? After the consumer society and the communication era, does art still contribute to the emergence of a rational society? Bourriaud attempts to renew our approach toward contemporary art by getting as close as possible to the artists works, and by revealing the principles that structure their thoughts: an aesthetic of the inter-human, of the encounter; of proximity, of resisting social formatting.

This is the box I made in class. It’s sized for .25″ material. I resized it in order to actually cut the box out of .125″ acrylic.
