DUS, a Dutch architecture firm, unveiled their KamerMaker ("RoomBuilder"). It is the first mobile 3D printer with the capacity to print inhabitable pavilions. The technology is based on the Ultimaker printer (essentially RepRap) but can print as large as 2.2 x 2.2 x 3.5 meters. It is housed in a giant chrome box that looks as if aliens had plopped down & begun building homes for themselves. Although arguably not quite large enough yet to build a pavilion in a single go, it could certainly fabricate the pieces for onsite assembly. The idea is to implement a more local & adaptable design approach, reuse available materials, & offer mobile construction of emergency & temporary shelter.

Arts collective panGenerator has created an interesting piece entitled FLOAT. It has surrounded a fish tank (that has a fish in it) with cameras. They plot the fish's movements, compile that & turn it into a 3D Printed sculpture. Exceptionally interesting shapes & patterns made by the random wandering of a fish in it's prison. Always wonderful to see information in a form we can study & appreciate. Would like to see this done with a colony of ants, a flock of starlings...or us in Times Square.

Mikola Lysenko has created an app to turn an 8-Bit character sprite into a 3D printable model with his Shape Carving Editor using WebGL and the Shapeways API. You can see some of his 8-Bit voxel sprite models in his Shapeways Store.
To use the Shape Carving Editor to make your own models take a look at Mikola's blog which has all of the instructions how to use the app along with all of the thinking behind the project....
The source code for the client is available on GitHub, so feel free to download it and try it out.
