Serial Slicing - Cardboard Federico Villa

Once the 63 individual sliced were laser cut it was just a matter of stacking them together and gluing them, and of course move to go along with the process :)

 The beauty about working with cardboard, in my opinion, is that it is an inexpensive way to show form and volume, but if you see it from the perspective of the structural support (interior) it can look almost transparent or show the interior structure perfectly.

I was very happy to see the finished piece and actually experience the power of 3D scanning.

3D scanning and replicating

For our first project, which involved 3D scanning a small sculptural object using the 3D scanner, I was inspired by architect Zaha Hadid and developed small chess pieces which communicate through a sculptural format. 

 From the pieces that I had made out of Ren foam, I selected the queen to scan and replicate using the 3D scanner since it plays well with light and shadow. I took the piece and using Rhino, then contoured the body in order to cut it up and prepare it for laser cutting. Dowel holes were added for structure and alignment.

Once the model was exported to an obj from RapidWorks, I imported the model into zbrush to clean up the polygons. 

Original geometry

Using the Dynamesh command in Zbrush, I evenly dispersed the polys throughout the object resulting in a much cleaner mesh.

I used Dynamesh in Z-brush to create several different high resolution and low resolution versions of the object.

After the model was exported as several obj files, I imported the low poly object into maya and experimented with creating a wire frame version.

For this project, taking inspiration from H.R. Giger, I created a small WED clay sculpture.  The sculpt is roughly 4" tall so it works well with the 3D scanner's short range focus.

Next, the sculpt was sprayed with Kryolan Crystal Clear to seal the detail during the scanning process. The quick creature sculpt was then taken to the scanner.  I added several tracking points which make combining the geometry from each scan easier.

Positioning the sculpture is very important in order to receive a clean scan. If the sculpt/object is not in focus then the scanner does not read the geometry.

 In order to capture enough of the sculpture to work with in Rapid Works, Zbrush and Maya, I had to scan the object 360 degrees from three different positions.

After the sculpture was scanned, I combined the scans from multiple angles to create one mesh.  I also cleaned up the geometry and cut out the metal pole that appeared in the scan. Then I imported the mesh into Rapid Works, where I patched a few holes in the geometry.  After the mesh was fused to one and completely patched, I exported an obj file.

Next, I imported the obj to Zbrush in order to clean up the geometry.  More information on mesh clean-up coming soon!

This is my posting of My Scanned Image. The Image is based on an African Nkonde Figure.

I will be using it throughout the quarter to explore digital fabrication processes. To see Other works that I have created using this subject you can go to my Flickr page.

Brianna Finkle: Radial Waffle Stucture

Once grasshopper was available, it was time to make some waffles structures. Below is a quick example of a radial waffle structure which might make a really interesting light fixture.

Brianna Finkle: Polyhedra

 Below is some experimentation we did with polyhedrons. While working with the compound of two squares I started with an Illustrator file which was then brought into Rhino and the exported for the laser cutter.

Brianna Finkle: Serial Sliced Object

After becoming more familiar in Rhino we learned how to serial slice an object. After inserting a core and slicing the object comes a process of numbering and laying the components out on a flat sheet to be laser cut. Once the pieces are cut the assembly is simple.

Brianna Finkle : Slotted Sculpture

Below is my first exploration in slotted sculpture. Starting with a Rhino file that was laser cut, several small pieces were created that can be arranged in many different ways.

Andrew Landers: Poly Shape Paper cut

I started by making a model in Maya to export as an Obj file to send to a program called Pepakura which unfold the object for me so i can then set it up to be printed out.


Here it is in Pepakura,




Then you put it in Illustrator so you can fix up the cut out lines for the laser cutter.



Then you throw it back in to Rhino with all your new edges and you can finally print out your pieces.
