There are thousands of flows of energy all around us all the time, and I enjoy trying to make then visible. We make use of only a few of these energy pathways as they make there way from higher ordered/lower entropy sources to low order/higher entropy sinks.
## Assignments
Design and produce something with a digital fabrication process (incorporating computer-aided design and manufacturing) not covered in another assignment, documenting the requirements that your assignment meets, and including everything necessary to reproduce
it.

I explored a number of things - 3d printing with clay. molding and casting tempeh, bamboo and digital fabrication, and working with cutting fabric on the laser cutter, composites and precious plastics with MDEF.

## 3d Printing with Clay
To complete the assignment, I used a modified 3d printer to print with clay. IAAC and Eduardo have extensive experience in 3D printing paste materials like clay.
A Crealty Ender Pro printer was modified to print clay. it was fitted with an industrial pressure tube filled with clay pressurized to about 3 bar with air. You can print anything that can be made into a paste with this tube. The tube pushes material into a feed screw nozzle that pushes out a 4 mm line of clay at a rate the depends on how fast the screw turns.

This week I also experimented with making tempeh using advice from Barcelona based Domingo Club open source tempeh making company. Maude from Domingo Club is working with MDEF students on a number fo projects and I ran into her at IAAC. This is one of the things I love about IAAC.
Tempeh making is a process of molding and casting. Cooked soybeans are inoculated with a microbe then placed in molds. Over 36 hours the microbes create a mycellium-like mat that binds the soybeans together into a unit in the mold and makes them more digestible.
Maude's company Domingoclub has several open source designs for 3D printing tempeh molds and incubators. They are on the Dongoclub website [here](https://domingoclub.com/documentation)
