Fabrication
Materials
A variety of materials were considered for the fabrication of the incubation chamber. For the outer and inner shell, it was necessary to use a material that was easily cleaned and maintained. The inner shell needed to be highly impermeable to moisture, so a humid environment could be maintained inside the incubator. For these reasons, we focused on metals and plastics.
INSERT TABLE1
We eventually settled on rigid HDPE. In addition to being the most cost-efficient material, HDPE is relatively easy to machine, especially when compared to metals. When considering insulation materials, we once again had a plethora of options. We were in need of something that could properly insulate without adding too much bulk to our incubator, so we planned to use insulation that was no more than an inch thick.
INSERT TABLE2
Once again, we went with the most cost-efficient material, as it provided the best insulating properties for the price.
Assembly
HDPE plastic was cut to the proper dimensions in the Clark Hall machine shop at Cornell. The polystyrene insulation was cut with a jigsaw. Pieces were affixed to one another using a silicone adhesive. The outer shell was assembled from these pieces, once again using silicone adhesive. After the outer shell had thoroughly dried, the inner shell was put in place.
