Rex Brodie – Project 2 FDM Update

I really enjoyed seeing everyone’s work at our critique this afternoon. I will definitely put my newly learned digital fabrication skills to use next year in my sculptural work. Here are couple of pictures of the architectural model I created with my FDM print. Also, I decided to have some
fun with my final project by placing one of my models in context using an image of Salvador Dali.

Tamela Sicay-Perrow Final Posting

This is my last post of the quarter. Over the course of this class, I've been inundated with a lot of information that will take a long time to synthesize. I can only hope to use a portion of it within the lifetime of my artistic career. The images included can hopefully show the extent of my apppreciation of the class and my education. This rendering is the final proposal of what I can imagine my fdm surface population turning into.And this is the produced abs printed fused-deposition modeling "egg" that was later painted to match the mettalic finish in the rendering previous. This following picture is a screen capture of the ideal of what the pepakura file for the final project could have produced. The final model is flawed and is not pictured here, but the synthesis of this idea will continue. Once completed, I will post again to show the potential of the idea being realized.

Rex Brodie – Project 3 Laser cutting

For my laser cutting exploration project I decided to create a radial waffle structure of an asymmetric form. It took a couple of attempts before I successfully created a rib pattern that was aesthetically pleasing and functioned properly.

Unfortunately the Massive Unroll script was not working properly, requiring me to manual layout the laser cutting file. A few of my numbers were missing so the beginning of the assembly process was a little confusing.

I took a Forging class this summer and discovered that I really enjoy the process. I will create a forged metal base for this piece that juxtaposes the hand-crafted organic forged forms with the geometric laser cut form

Clay Royse - Laser Cutting

I was immediately drawn to the parallels between the serial build process and medical imaging, specifically the slices that MRI and CT scanning create. I had my first CT scan this summer, after a bike wreck in July left me unconscious and thinking it was March. Unfortunately, I didn't have the presence of mind at the time to request my scan data, so this is less of a self portrait than I'd like it to be.
I cut two of these skulls, in hopes that I could rearrange the slices and stack them in a way I found interesting. What I found most appealing was a form mirrored around the bridge of the nose, using half as many slices on the bottom. It creates a shape that is somewhere between a beehive and Admiral Ackbar.

Jeff Pruitt_Laser Cut_Final Update

During the last update for this project I was waiting for my material to get cut. Since then I have gotten everything back and constructed everything.
The pieces came out amazing, and the construction went very smoothly, I was worried about alignment despite the alignment holes being there, just in the fact the holes didn't seem to line up PERFECTLY, which might have been a problem but everything turned out ok.
After doing a rendering in a clear material I wish to do this with it next

Jeff Pruitt_FDM_Update_ End

Last update for the FDM project. Last time I didn't really know what to do to finalize the project. I painted the sphere itself black, reason being simply I want to use this deliverable as a form study for future projects, and too much color might get in the way. Realizing it was...... really boring, I decided to attach some of the fallen off pyramids to expand the object beyond the "sphere" area. The red on those pyramids is simply to create a focal point on them.

David Markus | Laser Cut Project

For my laser cutting project, I decided to do an acrylic lamp based on a serial process. My limitations were to have a rigid structure using 2 sheets of 1/4 18x24 acrylic.

I started by stacking a row of polyline rings before using the taper tool to create a more dynamic shape.

After doing this, I created 2 half-lap interlocking supports to hold the segments in place.

I created the stair-like pattern on each support by extruding the rings down and then using the resulting shape to trim the surface.

In order to maximize my material, I arranged the rings inside each other where possible. After laser cutting, I assembled the lamp using Tenax 7R acrylic glue, which produces a near invisible seam. I had prepared the lamp to be hung from a 1.5 inch hanging lamp fixture.

After trying many different types of bulbs, I settled on halogen due to its crisp light and strong illumination.

David Markus | FDM Project

For my FDM project, I wanted to create a form that would be nearly impossible to produce through any other method. I started in a program called Cinema 4D, a polygonal modeling tool.

I first started with a basic dodecahedron shape.

I then used the Matrix Extrude tool on all faces to create twisting "limbs", ensuring that none of them were self-intersecting.

To smooth out the shape, I used a Hyper-Nurbs layer. This tool simulates a nurbs surface based on the polygonal data and allows you to specify the outputted poly count.

I then used this module in a polar array to create a complex, intersecting form.

After boolean unioning the object, I prepared the mesh for STL printing.

A few days later, I received the freshly printed object and began the process of finishing it. My intention was to smooth out the object as much as possible.

I started by lightly sanding the excess residue before spraying it with high build primer. Getting into all the "tentacles" was a challenge in itself.

I then chose a very intense red color in order to disguise the STL printing artifacts. I finished by spraying a high gloss clear-coat finish.

Due to the planar surface, I imagine my FDM project being used as a super-modern coffee table. All it needs is a pane of glass and it's ready for any super-high end post-modern minimalistic space.

David Markus | Milling Project Update

I was extremely pleased with how my milling project came out. I was afraid that the channels might be too deep or that odd angles might be difficult for the CNC to fabricate, but was surprised to find that everything came out extraordinarily well

I decided to use metallic gray automotive paint, but before that I had to prime and fill the porous yellow foam to prepare it for spraying.

I then put down my base coat of BMW metallic grey.

Before finally spraying a heavy layer of clear-coat to complete it.

Tamela Sicay-Perrow Progress Report

While continuing to work along with project's 1 and 2, the processes which I used are as follows. For the yellow foam cnc'd project, I coated the surface with a mixture of acetone and spot putty from an autoparts store, these form a seal after several coats. After letting it dry completely, and with minimal sanding I was able to coat the form with a smooth-on mixture to create a flexible mold.
This is what the mold looks like after complete drying to demold the original part. It is now ready to pour in whatever moldable liquid you might want to use, such as plaster, hot wax, or resin. This entire process doesn't need a mold release agent, and while messy, is less than expected.
Products used: yellow high density foam, plaster, burlap, smooth-on rebound 25, 100 percent pure acetone, and Dynatron glazing and spot putty.

Clay Royse - FDM Project

For my FDM project I modelled a sphere out of discs. To me, this was the best way to represent the themes of dimensionality covered in this class. I can't speak for the rest of you, but I find working on a three-dimensional object represented on a two-dimensional array of pixels using a 113 buttons and a sliding control device deeply... strange. My best analogy is that it is akin to learning how to knit while wearing mittens.

To turn this beige object into a public art maquette, I used polyester dye. Since I couldn't find a pan deep enough to submerge the entire piece, I had to keep turning it. This resulted in the uneven color you now see. The dye didn't take on the outer surface, but because the heat involved opened up some of the plastic "weave," a good deal of it migrated into the hollow middle of the piece. I think it looks a lot better than if it had been a more uniform grey.

Jeff Pruitt_CNC Mill_Update

Update on milling project. Looking at the results from the mill my original plan for my project doesn't look as feasible as before.

If I was to vacuum form this, most likely I wouldn't be able to remove the plastic from the piece, I did think of craft foam but I wished for something a bit more substantial and rigid. Instead I decided to make a mold of my form and make multiples for a modular tessellated product.

Thanks to Prof. Scott's generosity I was able to produce nine pieces. I'm not sure yet as to what to do with these nine pieces.

Jeff Pruitt_Laser Cut_Project 3

A serial cut was what I wished to attempt for the laser cutting project. I was unsure of what to do at the beginning and started fooling around with towers and twisting shapes. Taking curves joined to make somewhat of a square, I rotated and shrunk the curves, in order to create a twisted tall tower.

After making the twisted tower and seeing what I could do with it I took the curves and created an inner "tube". By taking the curves used on the outside, reducing the size of them and switching the angle of the rotation I was able to create an interesting interior.The one thing that I hope works out well for this is I made the serial only 90 pieces high. The tower rotation is also only 90 degrees. I rotated each slice 1 degree, this way since my chosen material is cardboard, the corrugation should follow the rotation of the tower. Updates to follow on how this goes.

Jeff Pruitt FDM project 2

When starting the FDM project I had no clue on how to go about starting, nor any direction in which to start with. From taking our little tutorial in Grasshopper and seeing the possibilties there I began to think the I could possibly construct something using this program and work with it more once it was printed. After fooling around with the program for a bit and understanding its capabilities a bit better I decided that I wanted to use the program not to simply create a final model straight out, but to use a few models within the program to produce a single finalized concept. Using multiple models formed in Grasshopper I started removing bits and pieces from a single sphere. After getting to a point I was content with I touched up a few places here and there.

A single object was nice but I wanted to go further and therefore attempted to create a stand for said object. Using one of the surface populated spheres from grasshopper I basically peeled it down in an attempt to create a stand.

When retrieving the printed object it came out much larger than I anticipated, (yes I know how large 6 inches is you just don't realize it until you have it) the stand also seemed to fall apart. I
now have a ring of pyramids, a big sphere ball thing, and a bunch of little random pyramids. I think I might attempt adding the pyramids to the sphere, I will update with how this goes.
