Project 4 – Design Concept
For project 4, we were asked to think of 3D objects and sketch it using isometric sketching. After that, these objects needed to be combined in one cohesive composition. In my case, I tried to sketch some objects but did not have an idea of how to combine them in one composition. What is more, isometric sketching of simple objects is tricky, and sketching complex models is even trickier. After some trials and failures, I was advised to go to the Fusion 360 and play with sketching and extrusion, loft, sweep, and so on there. After some time, I have got an idea of creating a composition consisting of playing card suits – a heart, a diamond, a club, and a spade. I implemented the modeling first, and only then tried to sketch them on paper. This was not the easiest part, because the models have complex shapes, but I already knew what I was going to do and this process was easier for me. Even though the sketch is not perfect, and there is room for improvement, I think it still translates my idea. The result is represented in the following image where the top part is isometric sketches of four bodies and the bottom is a top view of the composition.
Project 4 – Fabrication Final
For project 4, the main goal was to create a 3D composition that was later used to create a mold. The first step was to create an isometric drawing of objects that later had to be combined into composition using specially gridded paper. I tried to create this sketch, but it was not successful because I had no idea in mind. Then, I went to Fusion 360 and started sketching and using lofting, extruding, extruding, and so on. After couple of hours of trials and fails, I finally got the idea: a composition consisting of playing card suits (spade, club, heart, diamond). For this composition, I used mostly extrusion to create an effect of implied motion. To create a convex part on the top of it, I deleted the heart’s top surface. I replaced it with another convex surface (needed to adjust some parameters, the flow for this operation I found in one of the videos on youtube). This operation created two open bodies, that I stitched together using the stitch tool in Fusion. After I created all the bodies. I placed them appropriately and combined them using the combine tool. I also added micro beveling where it was needed. To create a valid mold, it was important not to have undercuts and not apply micro-beveling on the positive body’s bottom edges. After all these operations, I created a 6″x6″x1″ box, placed it appropriately, and used a “combine” tool to create a mold (negative model). Then I flipped the mold, and it was ready for fabrication. The actual fabrication took approximately 90 minutes. The result is represented in the following picture.
Project 3 – Fabrication Final
For project 4, my idea was to create a “covid pear” that would wear a mask. In a process of creating this surreal composition, I encountered a problem with a mask that could be solved by modeling a mask by myself. However, at that moment I had already combined my scanned pear and the head I found on Thingiverse, and they looked really good and interesting so I decided to stop right there. To create this model, I scanned ceramic pear found at the thrift store not far from my home using MakerBot Digitizer. In addition to that, I found “a full-size human head modeled … for placing headsets on” by lehthanis on Thingiverse. Both models were processed in MeshMixer to reduce a number of polygons and so on. After that, I transferred them into Fusion 360, where I first split the head into two bodies, so I had only the face, and combined it with the pear. After that, my peer and I printed our models overnight (it took about 5-6 hours to print both models) on a MakerBot 3D printer using the white filament. The result of final fabrication can be seen in the following two pictures.
Here is a final design for this project:

Project 2 – Fabrication Final
For the topo transform project, I used the stacked slices construction techniques and the black museum mounting board. The laser cutter has specific settings for each material so it could be cut safely. In my case, I should have had only one pass, but it actually took two passes. All in all, it took about 90 minutes to perform this job. After cutting, I carefully numbered parts and later at home assembled them using Elmer’s fast-drying glue. I used styrofoam to stick my dowels into it to make the assembly a little bit easier, but at some point, something went wrong and one side of my model looks a little bit twisted. The result of this project is represented in the following pictures.
The following picture is a logo etch. To produce it, I used the given settings for the laser cutter for the material and did 10 passes. As we did two etches at the same moment to save some time, these 10 passes took approximately 40 minutes. After that, my classmate helped me to trim the excess material (I am too bad at cutting straight lines).
At home, I used my logo etch as a stamp, and I really like the result that is represented in the following picture.
Project 4 – Design Final
For Project 4, my idea was to create a playing card suits composition. In the design iteration post for this project, I talked about creating all four suits, but after inspection, I realized that some parts of the composition were too thin for the drill in the CNC router. I had to inspect all parts of the model using a measuring tool in Fusion360 and thicken them up where needed. After this modification, the model looked a little bit different, but it is okay. After placing all the bodies in the correct position, I joined them using the combine tool, and the result is seen in the following embed. This is a positive version of the model:
After that, I had to create a mold that would later be used in the final fabrication. I created a 6″ X 6″ X 1″ box and placed it over the model’s positive version. Then, using the combine tool, I got a negative version of the model, which is represented in the following embed:
To sum up, using the visual principle of contrast (when the qualitatively different objects and events occur in the same visual field) learned from references and the knowledge of parametric sketching and geometric modelings such as extrusion and loft learned from exercises, I was able to create an interesting composition consisting of playing card suits.
