Concrete Hands

For a few months I've been involved in the production of folded PETG structures for the purpose of concrete castings. The project and research is accumulating as an installation under the Research Through Making grant, led by Maciej Kaczynski, and carried out by an esteemed group of TCAUP students. My involvement in the project is to expedite the digital construction of the 3D global form and the production of the to be folded 2D PETG pieces that compose the overall structure.

To expedite the digital workflow, I wrote a few python scripts within Rhino. The overall workflow starts with a desired surface that approximates the global form which subsequently is used to construct Rhino geometries and surfaces. Those surfaces are later unrolled and converted into line geometries that represent the cuts and creases that will go into the production of the to be folded 2D PETG pieces. The entire process from surface to 3D global form to 2D PETG pieces is automated from start to finish and with the press of a button.

The PETG is cut and creased using Zund knife cutter. The pieces are then folded and assembled with staples and rivets. Above is an example of a PETG casting structure and below is a sample concrete casting in result.

The installation for the Research Through Making grant is in production and will be unveiled later this week. The first picture in this post is the final concrete casting setting.

(Portfolio) Jason Prasad

I recently compiled a portfolio of selected projects from my career at the University of Michigan. Much of it will be seen on my new website too.

Harvesting Rhinoberries

As a part of my masters project at Taubman College I created a series of 3D printed lamps I affectionately name Rhinoberries. The lamps were designed using Rhino Python and T-Splines. I'll have more documentation and some source code on my new website once its complete.

For the past semester, I was a collaborator in a project using the KUKA 7-axis robot to sculpt clay. I learned how to operate the robot through the process. The ideator of the project is Mat Schwartz and more information about the project can be found on his blog. The research focused on the reuse-ability of the clay in using it as a surface to cast into or to layer fiberglass. Clay tools used in the research were fabricated through use of a waterjet.

Translations Project: Final

For my final translations project I decided to explore two techniques: the first was to contrast a 2D patterning with a 3D topology, and the second to use smooth changes in topology to best expose the layering of material in the object.

The process involved routing out the 2D patterning, of which, was based the border of a parametric surface I plotted in Matlab...then casting into the patterning with mixtures of plaster and urethane...and subsequently routing out the surface which I had modeled using T-splines.

Stool Design I: Digital Fabrication

I'm trying to get in the habit of designing stools since we are planning to fabricate a few in a course of mine. I've decided to learn some T-Splines to accomplish this. This is my first stab at designing a stool consisting of a wooden frame and what I'd hope to be a fiberglass skirt. 


Below are a few stool designs I've researched and will be the inspiration for further iterations.

Parametric Surfaces from Matlab


My current research in the MS_DT program has been to use scripting and a more mathematical approach to the realization of form. I'm basically re-living my college calculus days. To accomplish this, I've been re-learning Matlab and Mathematica. I was entranced by the beauty of surfaces derived from differential equations and other mathematical descriptions and thus changed my own research trajectory. I would love to gain the methods to perceive more complex forms through higher mathematics and abstraction.


I will be designing decor pieces for this research. Much of the fabrication of these pieces will be via 3D printing. Below is a concept of a lamp based on one of the surfaces I encountered in my new exploration. 

By exploring the endless avenues that mathematics offers, new and exciting variations of form can be encountered. I've been captivated by typing random equation and tweaking ones I've tried. 



I would eventually like to approximate more organic looking form through mathematical phenomena. This will require a lot of effort on my part to research more math. I like the idea of designing through mathematics but in such a way that it is not immediately apparent through viewing the output. I plan on producing a phylum or taxonomy of the forms I generated.
