A truly fun and freeing group project was sand casting wax seals. The purpose of this was to gain experience in the designing parts that would allow the mold to be released from the sand. We pushed the boundaries and ended up with very shallow designs, but learned what we would need to change for the next time. I designed the pattern that was 3D printed and worked with my group members to complete an honest analysis in the memo of what went well and what we would change. The biggest issue we ran into was the size of the designs we wanted to indent into the wax seals, the small spaces didn't allow enough draft angle and the sand wasn't able to escape the mold. This practice of reviewing what went well and what didn't is important for any profession and especially for engineers. I will use skill this in my career when communicating with my boss a review of a project or a progress update. To try and fix the designs after sand casting, we used Dremel tools to emboss the patterns into the seals. However, this resulted in varying levels of success in sealing envelops with, unique, designs.
