Sami Lee Woolhiser: Pepakura files

Here is my practice for pepakura, we took a shape from the database. No pepakura program involved here, just illustrator and rhino. I live traced a flower design and pasted it over my shape in rhino to give it a cool engraving.

Here are the files for my pepakura wolf. First we take our model into Pepakura. Then cut and dissect the model into flat puzzle pieces using the knife tool and organize using the move tool. Where the flaps overlap you have to split the pieces with the zipper tool. Then we have to move the pieces into illustrator so that we can translate it into rhino.
Layers: Outercuts=magenta, innercuts=blue, text=red (make sure to convert text to curves, the laser can't read text objects)
These are crucial because the laser cutter will translate certain colors into certain cuts.

Sami Lee Woolhiser: Heightfield Mold

Here is the making of my mold for the milling project. I used Rebound 25, a brush-on silicone rubber material.

 Here is the mother mold, a harder shell made of burlap and plaster to hold the form of the silicone inner mold when casting.

Sami Lee Woolhiser: Deer 3D print

Just picked up my prints from the shop! They turned out awesome. I lost some of the detail in the tops of the buildings because it can't print anything smaller than 1/8th of an inch thick. No matter, i can fix all of the little details manually.
I even managed to fit two large and one small in the print envelope of 5x5x6.

It was also in my first show last night! May 10th, 2012

CB Lam 3D scanning

Hey everyone! I finally mirror the t rex.. after a long battle with Maya..

Maya!

CB Lam - 3D scanning and editing

Hello everyone! hope projects are going well for y'all, this is T rex skull I chose for 3D scanning, and I here are some problems I ran into during the process.

In this pic I am trying to fill up all the holes on the mesh. I had a hard time scanning the inside of the jaw.. and some of the holes are self-looped, so I need to expand the hole and refill'em..

Simplified, reduce polygons to 20000. the lower jaw still messed up. I decided to mirror the left side of the skull and finish the detail by hand, so I don't have to do so much on the computer

Gold T rex skull! hooray! Keyshot*

There's when I ran into troubles, I am still trying to figure out how to mirror and merge them..

From Start to Nearly Finished

These two pieces are roughly inspired the Rorschach inkblot tests.  I really wanted to give off the feeling of strength and self empowerment.  My intention is to bump up the scale for the rest of the series.

This is an Alja safe waste mold, which is made of a two part mixture of water and aliginate.  I poured plasticine in liquid form, I usually put my oven to 400 and it melts in around 10 minutes. 

 I used the 3-D scanner Next Engine and ScanWorks to clean it up. My poly surface count was through the roof, as expected, so I had to simplify the scan slightly.

Once opened in Rhino I put a flat base on fist by drawing a straight line and then using the command split.  I then capped the open surface and used the mirror command to reflect the scan. I used grasshopper to section the piece up in 1/4 inch slices and used 1/4 inch round dowel rods. In the future I plan on used square rods.

This piece was milled from pine.

Cut on Luan.  Pre-glue up

If only I could cast in rose gold!

Cherry wood pictured.  In my final piece I want to glaze oil paint over the form to replicate skin.

Sami Woolhiser: Project #3

"Caught in the headlights"

Here is a model I made for 3D printing (3DM) and pepakura. I took a few models from a database library. Here is a collage of a deer model, bridges and buildings which I manipulated to create my desired form.

Here is the model in Rhino

 There were some issues with the deer model so I took the file into Maya to clean up the mesh to get rid of all the manifold surfaces. I had to separate the leg and make that a separate shape from the main body. I will just put these two shapes next to each other and they will be fine in the 3D printer.

Fix in Maya

 Here is the final model in Rhino. I made sure to convert all of the models from polysurfaces to meshes so they would print properly. All clean meshes! Some of these I had to remodel because of some issues with the original data.

Here is the model in Keyshot, some cool renderings with a metal and wood.

Logan Miller: Laser cutting

Hi everyone,
    This is my laser cutting file. I planed on making a stand for some earrings because my major is Metals and jewelry. so here we go.

This is the model all finished. It is 12'' tall and is going to be serial sliced and made in luan.

After running the Grasshopper Scrip i generated a layout for the laser cutter to follow.

This is the keyshot image of the final planed sculpture. future images will be uploaded of the real life stand.

Trouble Shooting and Brainstorming

 My original intention for this course was to make a piece using fingertips pressed up against each other and repeated to create a large panel. The meaning behind the concept has not been fully fleshed out, but I do intend to return to it.  In these castings I used my roommates and my own fingers, making a casting of our right and left hands. This is an alginate mold, which is a part A and B mixture of water and Alja-safe.  If you are interested you can purchase them at http://www.smooth-on.com/Life-Casting/c3/index.html or kindly ask Prof Scott for some :)  I melted plasticine clay to fill the molds and surprisingly I was able to get several casts.

Logan Miller: Milling

Hi guys,
       this is my first blog posting i hope you enjoy. This is my milling file that was based off a height-field  image of water. i plan on vacuum forming plexiglass molds off of it.

these are the two stands laid out and ready for milling

placed the two files next to each other to get the most out of the 20x20 material.

this is the keyshot image in wood
