I wanted to give you all an update to my sensor housings project. Â With the construction and plumbing issues I was relocated to Dr. Harnett's lab for a little over a week. Â Previously it was concluded that we needed to mold the housing in order to reproduce it in a fast and effective manor. Â Just printing them would take far too much time and produce very unreliable parts. Â During that time I was able to take advantage of some of the supplies in her lab to start experimenting with molding.
There were three different materials that I tried during this time. Â One was a paint on mold and the other two required are silicon based rubbers.
The two above were using materials found in Dr. Harnett's lab. Â The one on the left pulled away from the part and thus did not make a usable mold. Â The one on the right, the chemicals were old and questionably usable. Â It didn't solidify and eventually I decided to throw it away. Â I also ordered some fresh material as well as resin for pouring into the mold to make parts.
This mold was actually successful, but also it did a very good job at 'remembering'Â the fine details. Â With this mold I was able to pour plastic resin in and successfully make a near identical replica.
This shows that this method of production is reasonable in order to produce our housing. Â The next steps for this are to get a final piece that I will base everything else off of. Â Also I would like to see how many parts we can do in one mold in order to make production faster.
