Jesus Vela: Project 2 Week 8 3D Printing

Ghosted View and No Naked Edges

Concept

     In the context of shape, the design of this pendant is based off a geometric pattern I created in an earlier painting of mine. Materials were inspired from popular crystal pendants. The materials lend themselves well to my design considering how rectilinear it is. 


Layers

Techniques

     The gridsnap aid me achieve a symmetrical appearance in the pendant. I started by laying out  polylines based off the geometric pattern in my painting. Each polyline was assigned its own layer: Inner V, Hear, Outer V, and Periphery. Next I extruded each polyline to the same height. Making the triangular tops to each layer required that I use object snaps. Most joints were made by half-trimmed cylinders. One joint was made using the arc tool. I created a Boolean union to get rid of unnecessary lines between layers. When unified, naked edges were not apparent, but I did explode pendant only for create the layers image in this blog. I did not have to scale the pendant to be lesser than 4" in each dimension.

Materials

     Crystal pendants are often made using a crystal and wire, but wood has also become a popular additive to pendants. Lighting was important to convey the aesthetic realism of the crystal pendant. Materials used in Keyshot for rendering the pendant include: Ginger Bronze, Glass Red, and Glass Clear. Brightness was increased to help distinguish the curves around the crystals. Refraction was also increased to help the crystals look realistic. During the actual 3D Print, I chose blue because of what was available at the location I printed at. Looking at the pendant physically helped me decided that the top edges of the pendant shouldn't be as tall as the rectangular base.

Anna Phengsakmueang Week 8: 3D Printing

Concept:
Pendant Inspiration
Inspired by an anime I previously watched, I thought of creating a crystal pendant similar to the main character's necklace. It was a light blue crystal with wings wrapped around it, both characteristics of which I am fond of. I also wanted to make sure to include a loop for another loop to attach to so that it can be added to a thin chain for an actual necklace. Rather than make it intricate, I preferred a more simpler design, so I chose to make the wings smaller and spread out rather than wrap around the crystal.

Process:
Ghosted Image Painted Black

To create the crystal, first I made a pyramid and laid it down onto its side. Then, I made a truncated pyramid, laid it on its side, rotated it so that the base lines of the truncated pyramid were parallel to the base lines of the pyramid using several perspective windows and then scaled it so that the bases of the two pyramids would line up together. I wanted to also create a base for the crystal to attach to the part that is connected to the loop for a necklace to go through, so I made a duplicate of the truncated pyramid, scaled it to be a bit larger than the original and used the trim tool to just keep a small portion of the pyramid for the base of the attachment to the loop. To create the part where the crystal would attach to a loop for a necklace, I duplicated the small truncated pyramid I previously made and scaled it to be larger. Throughout making the crystal, I made sure that the bottom edge of the crystal was touching the ground while also scaling the larger portion of the attachment to barely touch it as well. I also ensured to center each piece according to the center of the pyramid half of the crystal shape. After that, I proceeded to merge the two pyramids together using the "Boolean2Objects" command, so that I would get a single crystal as the result to place in a separate layer for rendering. Then I continued to work on the attachment portion of the crystal by using a torus for the loop that the necklace attaches to. To attach the loop to the base of the attachment to the crystal, I used the "Boolean2Objects" command. To enhance the look of the crystal pendant, I deformed a sphere and duplicated five more of it, to create the rings that are on the loop which were each attached using the same command. When I was done creating the general model of the pendant, I separated each portion into layers and checked for any naked edges.

No Naked Edges


Materials:
Layered
For the materials, I kept it fairly simple. Going off of the inspiration of my design, I went with sapphire for the crystal in KeyShot, and aluminum for the loop attachment. I only used two layers since the pendant comes in two pieces. To add a bit more blue to the crystal itself, I applied a color to the material as well. For the actual print, I chose to get it printed in white, so that I can paint it with metallic acrylic paint later on. Another reason for my choice was so that the colors would show off a bit more on a white background rather than a black one.

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.

Brandon Wehenkel: 3d Printing Assignment



Black & White Ghosted


Colored Ghosted


Concept:
I served onboard the USS Leyte Gulf (CG-55) from 2010-2012.  When thinking of things to create in 3D I figured a replica of something I once worked, served, and lived on would have been cool to recreate. So my inspiration came from my familiarity with the ship.  I really enjoy boats and sea life so creating this complicated structure was a reminiscence of my past.  I didn't know how to start so I looked up videos on youtube and a boat builder for Rhino was very helpful.


Overview


Front


Modeling Techniques:
First I followed the tutorials I found on Mr. Peterson's youtube page.  Then I used Points On and molded the linear lines I created to make a skeleton ship hull.  I used roughly 3 different shaped curves to create the bulbous bow on the front of the ship.  Then about 7 more curves using the same technique to create the rest of the ship.  The bulbous part was the hardest because when I mirrored over the geometry with loft I found some clipping.  I spent about 3 hours just messing around with the points on the curves to create the right shape.  After I was able to successfully mirror over the hull with as minimal bending between the connecting points I used cap planar holes.  The backside of the ship (aft face) did not close with planar holes so I had to use blend surface and it worked eventually.  Throughout the entirety of the ship, I had done multiple cap planar holes and blend surface to close the shapes.  Most of the shapes are just boxes that were cut with a polyline projection and then used the trim and cap planar hole technique.  I did the same technique with the hallways in the forward, midship, and hangar section to create the "simulated" rooms where the doors are open on the main deck.  Everything else is just mainly shapes, which I  extruded or intersected into other surfaces so they would print right.  I used polyline/arc to create the curves in the guardrail on the forecastle (front section of the ship) and blend surface to close the shape.  That was a little bit of a challenge since some of the curves didn't want to close once I projected a shape to cut and trim. I missed a lot of details (ex, anchor, propellers, guardrails that aren't walls but actually rails) that I was hoping to add to the various levels of the ship but after a while, I realized the parts were going to be too small so I stuck with what I had.  When I feel like revisiting this model I'll edit the parts I don't like, and add the details I do want to make something that I feel is a completed piece.


The hardest parts were the curves in the hull and the gun mounts.  Those took the longest to manipulate to create a comprehensive surface.

Aft Missile Deck POV


Materials:
I used swirled aluminum and then changed the color.  Because these ships are just aluminium with deck grey paint on top.  The smoke stacks are rubber material because those are usually very hot areas where the paint melts off and all that is left is a dark burnt color.  It's dangerous to be around those because shards of metal can fly out of them at random times.  The radars and satellite dishes are plastic and I changed those colors to be a little lighter than the paint of the ship because they are irradiated a lot of the times from radio signals and their paint is usually fried as well.  The only difference is they aren't exposed to high amounts of heat.


Before Chemical Wash


 Size comparison with minor broken parts (not pictured)


First I looked up if just putting spray paint on a ABS plastic model would be fine without first fixing it with a sealant.  I came to the conclusion that spray paint doesn't eat the material so I risked it.
On the actual model, I started with a silver spray paint to make a shine. Then I went over it with a dull hammered grey spray paint to give it less of a brand new look. I did some minor touches with a brush. Then I painted the underside where the ship usually sits in the water with a textured red-brown spray paint to simulate rust.


Painting Rust


Painting Grey


I carefully painted a black line that separated the grey from the rust.  I continued to do some minor detailing with black painting the deck black and some of the weapon barrel tips as well as the smoke stacks.  Then to finish the model completely, I added the white CG55 on the front bow with its signature alphanumeric nomenclature.
