Fabaroni was a project from the How to Make (Almost) Anything Class of Fall 2007 (MIT) who decided to build a 3D Printer from scratch. They started to test the best material to use for this project. They choose food. After several tests they selected Pasta Dough.
“We looked at inspirations from prior fab folks who had built 3D printers from scratch, and decided to loosely follow the Fab@Home design [...] We were still undecided about whether we should use a material that required melting, or just one that requires shearing to flow [...] Food was chosen because its easy to obtain, non-toxic, and easy to clean up [...] Eleven food items (or combinations) were tested using syringes and nozzles in the CBA lab [cheese wiz, chocolate, chocolate sauce, marshmellow fluff, vanilla frosting, gummy bears, marzipan, oiled marzipan, pasta dough and peanut butter]. Group members tried to make single lines, taller structures, and looked for stable consistency. The winner was Pasta Dough for its good structure and speedy drying properties (good consistency, hardens pretty quickly, flows well)”
Mike Knuepfel explains where he got the idea of the “Keyboard Frequency Sculpture”
I’ve been thinking about and exploring the idea of using 3D rapid prototyping techniques to create sculptural data visualizations. One idea was to have elements or data of the sculpture represent the object itself. I didn’t really have any great ideas for a particular data set and was having trouble explaining my idea to people. I settled on mapping the frequency of each letter in the alphabet onto a key on the keyboard. I used this chart from wikipedia for the frequency of each letter.
Key frequency mapped to height of 3D printed keyboard keys
Marianne is a national emblem of France and an allegory of Liberty and Reason. She represents France as a state, and its values. She is displayed in many places in France and holds a place of honor in town halls and law courts.
In 1999, Laeticia Casta (famous French model) was ranked first in a national survey ordered by the “Association des Maires de France” to decide who should be the new model for the bust of Marianne. She became the model of Marianne for the year 2000.
Cornell University Chronicle online journal has an interesting story about the use of 3D scanning and printing to replicate cuneiform tablets from ancient Mesopotamia in the Lab of Hod Lipson, associate professor of mechanical and aerospace engineering.
A Next Engine desktop 3D scanner was used to take 3D laser scans of the tablets. After scanning, the accompanying software, ScanStudio HD was used for post-processing and outputting 3D printable files of the tablets. With the VRML file format, prototypes were made (using ZCorp powder-based ink-jet printers) that match the look of the original tablets in color and texture. The software also has the ability to output the files in STL format for creating prints using other printing technologies (FDM, SLA, etc.) that do not retain color and texture matching.
Original and 3D-printed cuneiform tablets: Left: original; Middle: 3D-printed reproduction; Right: Enlarged (x2) reproduction. Produced on ZCorp ZPrinter 650.
