Reforming Plastic for Hemisphere Model part 2

Reforming Plastic for Hemisphere Model 

part 2

Below are images of an oven for baking plastic. This was our first attempt to build a larger scale oven for a larger hemisphere model. We decided to make a smaller scale oven to proceed with our prototype.

Experiment: 04/16/2017 *******12:30 p.m.-7:00 p.m.


1. Heat gun- 1500watts- temperature up to +500 degrees Fahrenheit.
2. High-temp styrofoam
3. Wood frame: 24in x 24in
4. 0.008 Lexan plastic
5. CNC to make wooden ring for 18" hemisphere

* New larger oven design

* Used CNC to create ring for hemisphere model

* Scaled down oven, based on original oven model

This oven could produce a hemisphere of 18in in diameter.

Unfortunately, the oven could not withstand the higher temps need to melt Lexan.

Our second prototype oven did not produce the necessary temp to get the Lexan to a flow point.

Finally, we discovered that a higher temp material is needed for keeping the inside of the container heated without melting or warping the outside of the oven.

Reforming Plastic for Hemisphere Model

Reforming Plastic for Hemisphere Model

Phase One: Research how to inflate/heat hemisphere.
Phase Two:  Build a prototype oven to inflate/heat hemisphere.
Phase Three: Note any changes necessary to the material, time and temperature. 
Phase Four: How was the process successful? (and) How was the process not successful?

Experiment: 04/13/2017 *******2:00 p.m.


1. Heat gun- 1500watts- temperature up to +500 degrees Fahrenheit.
2. High-temp styrofoam
3. Wood frame: 12in x 12in
4. 0.008 Polymer plastic
5. CNC to make wooden ring for 8" hemisphere

--------------- Using a small frame, we were able to build a small oven to heat the test Polymer plastic
to a flow point.
--------------- We were then able to inject high pressured air into the heated plastic to create a small hemisphere. (image of the hemisphere is not shown)

Final Transpiration Concept

Final Transpiration Concept

This is our final design that was created in Adobe Illustrator.  The model will be completely transparent including the base and planter.  We choose to build our final concept utilizing transparent materials so that the transpiration process is clearly notable and measurable.

An Explanation to the Transpiration Experiment

An Explanation to the Transpiration Experiment

Elizabeth Demaray Transpiration Collector is an open source design for a plant based H2O purification and transpired water collection.  Thus, I feel that a greatest purpose for this experiment would be used as a renewable resource for consumable water.  How do we use the transpiration process of a plant to collect water for consumption?  First, thanks to Elizabeth, she discovered that the Peace Lilly produces an optimum amount of vapor that can be collected and measured.  How do we collect the water that is produced by the plant?  Therefore, using the basic instructions that were provided by Elizabeth, we were able to build a basic prototype to monitor the transpiration process of the Peace Lilly.  Miraculously, we discovered that the plant was transpiring a high amount of water vapor.  Next, we have a hypothesis to build a better apparatus that would maximize the collection.  Thanks to the collaboration of the biology department, we discovered that we could increase the amount of the transpiration process of the Peace Lilly by adding a stimulus.  Hypothesis, to maximize the transpiration rate of the Peace Lilly, we need to use a transparent plastic for the enclosure to allow sunlight (photosynthesis), a frame to keep the plastic cover off of the plant leaves, a device to capture the condensation created by the water vapor.  Further, we created a transpiration framework for the Peace Lilly utilizing a running hypothesis to maximize the transpiration rate.  Therefore, the experiment was successful as we changed a few variables such as removing the plant from a greenhouse setting into a temperature control room.  However, the transpiration rate was slower, the plant still produced a higher amount of water in this updated prototype.  Conclusion, the current data gave us a realistic idea of key variables to maximize the transpiration rate.  For example, we discovered that the greenhouse temperatures although higher produced an increase in water vapor, the volume of the container should allow air flow which directly effects the transpiration and the plant after enclosed over a period of time needed a period or break from the enclosure in order to prolong the plants life cycle.

3D CAM Model

Transpiration Project

3D Computer Aided Manufacturing Model

I will be attempting to 3D print my Transpiration model utilizing a Computer Aided Manufacturing Model.  This model will be approximately three inches in height by three inches in diameter.
