David Rake: Week 8 - Prosthetic

Concept:

As an avid Mechanical bike rider I aimed for a bike related prosthetic. From the original drawing to the actual model slight tweaks were made in favor of a more realistic design. Instead of trying to curve the gears around a leg shape they were laid flat so actual gears could be put in place and be kinetic as well. Another addition is at the bottom where the foot would normally be I put a typical clip design for clip in shoes on road bikes.

Technique:

Starting with the gears they were modeled with curves and the teeth were polar arrayed around the center and slightly modified for imperfections. The top gear has 16 teeth and the bottom gear has 12 teeth. The indents in the gears were subtracted later using booleanDifference along with the holes going through them. In regards to the chains they are made with curves as well. They contain of 2 circles and a small curvy hourglass shape with a larger version of the same shape just outside of it.

These hourglass shapes were alternated along the pattern to create the full chain link. The smaller gear is directly in the center of the larger gear and so the chain tapers off towards the bottom instead of going straight up and down which I found difficult to work with. After trying (unsuccessfully) polar arrays to wrap the chains around the gears I resorted to manually rotating the chain around, which was not near as hard as I thought it'd be.

 The 2 gears and chain were then duplicated and positioned around the origin. The Bottom gear was rotated inward to almost create a seal in between the sets of gears. A cylinder was added in the center with other cylinders matching the angle of the gears to ensure a flat looking cap. the gears were booleanUnion(ed) to the cylinders and the bottom piece was added on with more simple boolean cylinder cutouts in the bottom for clip in pedals.

Materials:

I used a darker metal (Anodized Black) for the inner cylinder and gears. The chain used a lighter metal to highlight it (Chrome polished). These two materials are ironic due to their real world counterparts where the chain would more likely be dark due to oil and more abusive wear than the gears. This reverse setup looked much better in this situation however. The other material scheme caused the inner pieces to be difficult to see in depth.

Chelsea Griffin : Week 8 - 3D Print

I knew before I even began my model, I wanted to create some sort of luminary. I looked at many different 3D printed lamps for inspiration before I stumbled across a particularly beautiful lamp that was a tree with a sphere of light in it's roots. I really love the look of spherical lamps. I also often find myself incorporating trees into my work no matter what the medium may be. This is why I was pretty stoked when I came across the Tree Stump starting point model in Mudbox. This was my first experience using Mudbox, and I was pretty much immediately in love. My only other exposure to modeling was Maya (which was an incredibly painful experience) as well as Rhino (a much less painful experience). Now that I know about Mudbox/ZBrush/etc, modeling is a like a whole new world for me. I still am fairly new to modeling so it's very useful that Mudbox has starting points you can work with. I took a Tree Stump and shaved it down and messed with it a bit. I kind of felt I wanted the sphere of light to be consumed somehow, perhaps by some kind of black sludge. With this concept in mind, I kept playing around in Mudbox until I was satisfied. In order to easily place a light inside, I attempted to hollow out the sphere and the base by cutting a hole in each, offsetting the mesh to an eighth of an inch. The base seemed to be hollowed out fine, but when printed, the opening I had created for the sphere was closed, though fortunately it was still hollow inside. I will have to figure out where I went wrong with this in my Rhino model. I ended up burning a hole into the base of the printed sphere using a soldering iron. Unfortunately, there was some sort of support material stuck inside the sphere that I had not anticipated. This caused the inside of the sphere to have shadows when a light was placed inside. I contemplated scrapping the idea of creating a luminary and just painting the sphere a nice solid color. The Keyshot renderings of metallic purple were pretty charming to me. But I came this far so I figured I would try and work with it. My model somewhat resembled a sort of crystal ball. I researched mineral spheres and noticed all of the lovely various colors and designs embedded inside of these rocks. I decided to paint over the sphere in a muted purple, trying to get a sort of crystal/mineral-like design. I frosted the sphere before and after painting it purple in an attempt to make it look a little more natural. As for the base, I mixed ModPodge, black paint, and black sand, trying to get the texture I wanted. I initially liked the idea of a sleek black sludge, but realized I kind of wanted a texture that would contrast the smoothness of the sphere. I figured the sand would give a nice rough texture. I was pleased with the outcome of the base texture. I wish that I had maybe used some different type of paint than acrylic for the sphere. I like some of the effects cast from the paint when illuminated but I probably would have been more satisfied if I had given up on turning this model into a luminary. I might later attempt to paint the sphere with a metallic purple or silver.    

Michael Hosler Week 8, 3D Printing

Concept/Methods/Materials:
     For this project, after being introduced to TopMod by professor Scott, I wanted to have a bit of fun, get familiar with the program, and sort of just see what came out. After seeing a few of the simpler things one can do in the program, I started with a soccer ball shaped polyhedron and extruded the pentagonal faces, leaving a small face on each extrusion. Then I connected those faces with interpolated handles and smoothed them with Doo Sabin re-meshing until TopMod could no longer handle the model. After hitting some snags with a few of the handles being twisted and tortured beyond all help, I used a combination of blender and rhino to simply cut them off and cap the holes which broke up the monotony of handles a bit. after finishing the modelling, I found myself thinking of this as some sort of custom glass installation so in KeyShot, despite some limitations, I was able to find a combination of materials, colors and texture that I was satisfied with. I went with a sapphire refractive glass and a rusty paint texture skin.
     As for the printed model, once it was finished I coated it with 2 or 3 layers of XTC to fill the lines from the printing process, followed by 2 or 3 coats of spray paint in various colors. Once that dried, I used a brush to spatter it with some darker, more primary-ish colors to add contrast and something of a variety. finally, I gave it one more coat or two of a glossy acrylic sealant.

Concept

For my 3D model I wanted to create a simple polygonal build that looked like a type of flower. I was intrigued at the idea of representing something from nature that is normally made of curves and smooth edges, such as a rose. My main goal was to have this representation be recognizable, but still allow room for varying interpretation.

Modeling Techniques

I created my model using the program TopMod and Rhinoceros. I mainly used triangular extrusion within TopMod to create the petal-like extremities. I then imported my model into Rhino to create a mesh and adjust any points I felt necessary. 

Materials

The materials used within this project included the 3D printing materials and paint necessary to create external design desired. The paints used were acrylic and were not watered down to achieve a completely solid look. 

Draven Ashorn-Hejl: Week 8 - 3D Print

Concept: My favorite game is Final Fantasy XIV, and in it your character wears a lot of accessories, including a pair of rings. One of the armor sets in the game is the Halone's Champion set, an angelic set of armor with a focus on wing imagery. Unlike many sets of armor in the game however, the Halone's Champion set does not have an accompanying accessory set, so I decided to make my own idea of what the rings of the set would look like.

Process: For the model of the ring, I kept things simple, as in Final Fantasy XIV their ring designs are all simple bands focused on highlighting one feature. In this ring's case, the focus was on the wings at the top, which I made by manipulating a sphere with Gumball until it was flattened, then cut a notch into it using BooleanDifference to add detail and some dimension. I then grouped multiple "feathers" together into a wing, then mirrored the first group to the other side of the ring to make the matching wing. To keep the wings solidly attached to the core band, I used simple cubes the length of the band to fill in the small gaps between the feathers. For some extra detail and flair, I added a 7-sided pyramid to the top as a small decorative gem, and cut small gaps into the core band of the ring so that it wasn't plain and flat all around. After the model was printed, I hand brushed on 2 coats of XTC-3D and then hand painted it with acrylic paint to finish it.

Materials: In Keyshot, I used Brushed Metal in gray and yellow for the core ring band and the wings respectively, but tweaked them to be more silver and gold. For the gemstone I used Blue Gem Stone, tweaked to be less transparent and rougher, with a deeper blue hue. For the physical ring, it was printed with basic 3D printer plastic, and I hand painted the ring with acrylic paints.

Concept
A 3D print of my week 1 castle. The print was done through Shapeways with little to no markings. Colors were redone to feel more like a monopoly token. All details were large enough to be printable, and difficult to paint. 

Model Techniques
Minimal modifications were made from it's previous design in week 1 such as size. It was designed by manipulating 3d shapes. However, materials in keyshot were swapped with matte plastics. Their colors were based on the paints available.

Materials
The model was printed using colored sandstone in this case a white polished color. Acrylic paints were used in place the metallic design originally designed.

Michael Crow: 3D Printing Assignment

Concept:
The Legend Of Zelda is my quintessential connection to all things nerdy. It is what made me want to pursue my career in animation, modeling and video games. In the N64 Game "Ocarina of Time" you are sent to several dungeons to collect "Medallions" to beat the game. To me each of these medallions represent challenges I have overcome in my life. I consider learning the ability to create physically what i perceive visual a milestone in my training and a talent to carry forward with me. So I decided to recreate these medallions and a base fitting them.

Modeling Techniques:
Each medallion started out the smae with a wide cylinder base, using a slightly smaller copy of the base with a Boolean difference to create the raised lip edge. From there it was mainly simple shapes, adjusted using their "Control Points" and duplicated to create the reliefs I needed to Boolean Combine or difference to get the shape I wanted. from there I was able to Fillet the edges to create a nice swooping join along the edges that wast to wide or to pointed.



Materials:
3D Print - The medallions were all 3D printed at the UT Dallas Art Barn Fabrication Lab, using ABS plastic. These were then coated with 3 layers of XTC-3D to give the model a more cohesive look and provide a primer for the different colored Acrylic paints. One different color for each of the Medallions. The base was laser cut from 11x14 sheets of .25" thick Acrylic. A base and a Top layer were cut and the sides facing each other were sanded down and conjoined using Super glue. Once that was hardened the entire base was sanded using 120 grit sand paper and coated in multiple layers of Black Gloss Spray Paint and the Golden triangles were attached with super glue

.

Keyshot - Starting with the base,I wanted it to be a dark stone color and texture, that way it would set a nice background for the colors used while also not really creating a distraction from the key parts of the piece. At first I wanted to make the medallions out of some sort of precious stone such as jade or ruby; depending on its color. However with such a dark platform the colors, being as transparent as they are, didn't get the effect I wanted across, instead much of their color was lost to the base. So instead I used textured and colored glass. It would make the model much more affordable, and even more importantly, give each of the medallions that transparent shine and luster, while still proudly displaying the color desired.
