Customizable Production II: Tree

December 20, 2009

This starts from a project for 4.510: Materializing Design by Prof. Larry Sass.

We made a web applet which support making customizable tree-like canopy for coffee shops. User can access to our website, build his own design in friendly 3d interface, take the generated CAD file to any nearby CNC machine and cut the parts from 3/4” plywood sheets. Following online instructions, he can assemble the parts with a few untrained men. Everything is finished locally.

We have tested the system with prototypes in various scales. The latest ones are 1:6 models made from 1/8” masonite with lasercutter. Metal pieces are cut with waterjet and hand bended. Right now the shape and angle between parts are chosen to simplify design and assembly. Next version in our plan will work with advanced machines and materials to support more flexible and fluid surface designs.

Customizable Production I: Umbrella Stand

November 3, 2009

This is a assignment for 4.580: Inquiry into Computation and Design by Prof. Terry Knight. We were asked to make an umbrella stand and discuss the question: to which degree can design process be made accessible for novice user.

We decided to make the most out of our limited material. Our design was a tripod stand with three holder for either long or short umbrellas. Ari did a fabulous job taking advantage of the flexibility of mason boards. The final design could produce 2 umbrella stands from 2 sheets (32”x16”).

Parametric method was used in the testing and implementing phase. The distance, width and angle of legs could be easily adjusted to reach the best performance. We believed this script could be hand to anyone with little training to produce his own umbrella stand. However, it could only exist after all joints were designed by us. It is not easy for a program to invent a way out of its catalog book to implement given design intention.

However, I am an optimist for a upcoming future of far more accessible design-making workflow. The architects tend to be reluctant to accept the idea that ‘anyone can design’. Actually, rural people, as well as city dwellers, have always been empowered to fabricate their own houses and furniture although this ability has waned with industrialization and globalization. If we compromise somewhat on the definition of design – and see it as decision making – ordinary people are already doing it while shopping or commenting.

I see the development in fast prototyping tools as opportunity for designers rather than crisis. One primary reason for architecture’s slow progress over history is the extremely time/resource consuming cycle of design, building and feedback, making it difficult to compare and learn from past experiments. I am doing further attempt on this later this semester for Larry’s class.

Moon Chair

October 21, 2009

This is a project for 4.510: Materializing Design by Prof. Larry Sass. I wam supposed to design a chair and run through the rapid prototyping process. My chair was part of a sphere, so it can rock/spin in any direction. The size was limited to one plywood sheet (8’x4′).

I was quite annoyed by the fact that our CNC cutter in the woodshop cannot perform 3D contouring (due to budget cut on software… errr). But I had a lot of fun playing with wood joints. The spine was cut into four segments so the plywood sheet could be used more efficiently. This main joint (#1×3) cost us more than 5 hours to put together. It was very strong. Slightly improved, I believe it can be used in larger scale wood structures.

The plywood sheet we had could be the worst material anyone would expect. It was brittle and cracked under CNC bits. I did realize that my design was not the best for this material in terms of reliability; luckily it worked out in the end (even for Larry) and looked pretty good.

I look forward to an opportunity sometime that I can combine 3d cutting, bending and all other possibilities in wood works. It can be really amazing.

Simple complexity

September 21, 2009

It was my first time using a laser cutter. I decided to start with a perfectly symmetrical geometry to keep things simple. I took a dodecahedron, making each facet a component, then dived into detailing it. The outcome had the smallest number of components, while got amazingly visual complicated.
