Shapeways Project

Below is the grasshopper script from my first attempt to make a chain link bracelet/necklace by following a tutorial. I used the plug in "pufferfish." It did not quite connect the way it was supposed to so I intend to try a different tutorial or make revisions.

Below is my second attempt at prototyping parametric jewelry. I switched from a chain bracelet to ring designs as demonstrated below. I also uploaded the design on to Shapeways and got some errors so I went back to Rhino and grasshopper and increased the wall thickness of the ring. I sent a scaled up version of some ring designs to the Ultimaker to test the design.

I am not sure why the second part of this tutorial did not work for me. I think my computer might have needed more time to render the map. I double checked all of my steps and I believe I followed to tutorial correctly, however I would like to go over it in class. Putting all of the polyline components in was tedious and I am curious if there is a different more efficient way to do it. 

I had some diffulty getting WeaverBird to work, but one I did, I found that playing around with the sliders and seeing the effect on the spehere was very cool.

I do not feel like I have a solid understanding of how this works. Some of my questions include: What does making the cylinder in Rhino do? Why couldn't we have made it in Grasshopper? What does the cylinder do and how is it used in the design? What is Brep?

Grasshopper Curves and Surfaces

This tutorial took me more time than the others, but it was not more difficult. I am wondering how deconstructing domain could be useful in design.

Grasshopper Basics Original Design

(Done in tutorial with Samu, but I did not take screenshots of the individual steps)

I feel that I now better understand the purpose of using Grasshopper for designs. I can confidently create polar arrays from lines and extrude shapes. I still do not fully understand piping vs extruding and the way that Grasshopper reads those commands differently/when they are best used.

3D Printing Challenge

2/10 

Today was mainly troubleshooting. The window bars on the Ewok house print were too thin and broke off with the infill, so I had to redesign them as well as the window in rhino. I also had the top layer hidden by accident so I had to reprint. Sahara was able to send the circular chain link pattern to the Ultimaker and we are awaiting its print as well as the new Ewok house.

Reflection:

Biggest challenge:

• Learning how to use Rhino commands and create objects with thickness

• Designing something that stretched my thinking, but was also doable

Biggest learning:

• I now feel comfortable designing on Rhino, exporting an stl file to Simplify3D, and printing with the Prusa

Biggest wish:

• I wish I could have been more efficient in my prototyping and design process so that I could have started printing earlier

Today was a shorter class, and after attepting to slice the ewok house in Simplify 3D, I realized that some parts of the shape did not have thickness and needed to be closed polygons. With Samu's help, each layer was isolated and the command OffsetSrf was used. Then, supports were added (with a thinner infill) in Simplify3D and the G-code was succesfully exported. Sahara successfully sliced the woven pattern and sent it to the Ultimaker for printing.

2/6

Today we retrieved a successful mushroom print from the 3D printer and decided that we could create something more advanced for the required overhang object. The new inspo was an Ewok village home which was succesfuly rendered in Rhino and ready for printing next time. For the woven pattern, the texture was changed from retangular chains to rounded chains and was successfully sliced and printed on the Prusa.

2/2

Today, Sahara and I brainstormed regarding the type of mesh pattern to use for our object design. Sahara worked on designing this in Rhino and I created a prototype for the overhang object. The idea was to create a tree which we did succesfully and sliced in Simplify 3D and exported to the Prusa to be printed. This is just a first draft of the object and the final will be more detailed and spherical (the leaf part of it).
