Advanced Studio: Digital Fabrication for the Arts

DUE Feb. 13, 2012 – Point-Cloud Model, Rhino command review, project sketch

3D Printer,Assignment,Description,Modelling,Rhino3D,Technique — Ali Momeni @ 8:41 pm

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.

DUE Feb. 8, 2012 – Point-cloud for 3d Modeling

3D Printer,Assignment,Description — Ali Momeni @ 4:54 pm

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.

Daito Manabe

These are two separate pieces by Daito Manabe. Daito’s huge hit was years ago after he published a performance/experimental piece where he electronically controls the muscles in his face. But still Daito makes incredible work. Highly computational and also highly fabricated. His work seems to have some bit of cultural divide, but still the passion is conveyed through the work.

Drzach + Suchy – “Time”, and an interesting Japanese furniture design.

3D Printer,Artists — Justin Lin @ 8:11 pm

Watch a video showing Time.

technique: shadow cloud produced via SLS 3d-print
size: 3 images, each 74 x 74 px, ball of diameter 36.7cm

“Time” is a 3-d printed orb that has a formless, unorganised geometric structure. From certain angles, the alignment of its skeletal shapes and voids causes it to cast a shadow that is a legible image. Here the shadow tells the time as a standard clock.

From other angles, the image changes to something else.

I am intrigued and amused by the procedure and choice of fabrication method in this piece. I think the use of 3-d fabrication here feels instinctive, natural, and neccesary: to make the sphere using analog methods, would just be a real pain. The motion of the sphere and the shadows coming into alignment and misalignment are a form of suspense and release that is very engaging. Having said that though, I find the reading of the clock, sundial, and giant orb as a little crude and really mars the elegance of the activation.

watch the “making-of” video, 0:40 for really finnicky 3-d printing post-processing procedures.

Another interesting thing that isn’t really 3-d printing or digital fabrication (but probably modelled in some sort of CAD software) is Yuya Ushida’s XXXX_Sofa. Its an expandable sofa/chair contraption hand assembled from chopsticks and metal rings. I like it because, going beyond the functional furniture design reading of it, it deals with issues of living (architectural) space, solidity, functions of the body, and interactions between bodies and materials/objects. I just thought this would be informative for friends interested in mechanical things to look at.
