Alternative fabrication methods using sand

Following on from the tutorial yesterday where Jack talked about possibly casting his experiments with sand using a saline solution sprayed onto the forms created here are two further ways of utilising sand to create rigid structures.

Markus Kayser - Solar Sinter

The first is a 3D printer which concentrates the solar energy to form glass structures from the sand the machine sits on. I know many of you have seen this before but I thought I’d post it in relation to this specific topic. The link is to designboom, a great website with daily updates from the latest innovations in architecture, art and design. Check out the link to find further information on Markus Kayser’s printer.

The second is a TED lecture given by Magnus Larsson. He proposes an ambitious project to stop desertification in the Sahara by literally forming a wall across the continent using the desert sands as a bulding material.

If anyone wants to edit this post to try and embed the video from the TED lecture go ahead, I can’t get it to work with their f=video format but that may just be me.

Arduino website

This is the arduino website where you can find very useful information on what an arduino can do, and how to use it. You can download the processing sotfware for free and browse and post comments and questions on the forum. 

This is the fritzing website, which is a sotfware that helps you design your circuit, share information and learn about interactivity

Andrew Kudless: P-Wall

Andrew Kudless (a.k.a. Matsys) demonstrates the parametric  techniques used to design the P-Wall and the building techniques used to actually physically create it. The project as such and especially it’s form might be interesting to anyone who is fascinated by Frei Otto’s pneumatic structures.

AA Make Lab at Hooke Park

The videos are from the workshop I attended in April. This particular video shows Michael Grau’s robot, which basically draws the intersection points along a wooden member as slashes in the right or left direction and writes a code consisting of a number and a letter, so later on when it came down to putting the structure together we knew exactly where and what direction to put the wooden members in. Time was running out so we used cable ties for both constructions. The final structure is a very organic form.

The  second construction was created by studying people and their movements on the site at Hooke park, the movements were  3d scanned using a hacked Kinect Xbox (acted as a motion sensor), then points were generated in Rhino to form a point cloud model. The points were joined together with lines forming a voronoi (a volume,form). We then used a robot which took the coordinates of each member from the computer and translated these to the space in the forest, it moved within the perimeter of the site and told us where to position each wooden member, so we cut the wood as we went along and connected each member with  an eyehook and a cable tie. Sometimes additional support was required that the computer did not account for, so we just added these. Also in the organic form the material used was not flexible enough to create the rounded shapes, as a result the structure kept breaking in sections and we had to add additional supports.

If we had more time it would have been ideal to test different types of material.
