Through the department of Mechanical Engineering, Cal Poly's machine shops serve as a student resource. Students can use these spaces to manufacture parts for club, class, personal, and research projects. They complete mandatory and optional trainings to learn how to use our machines safely, while student shop technicians provide those trainings and ensure a safe and inclusive working environment.
I started as a shop technician at the machine shops in January 2024. After training in this role, I applied for and accepted the role of 3D Printing Supervisor in March 2024. In this position, my duties extend to maintaining the shops' 3D printers, developing infrastructure to prioritize student accessibility, and performing commissions and design consultations for students, research groups, and professors using advanced 3D printing technologies.
Overseeing 24 3D printers within the machine shops, my duties are to keep the printers operating, calibrated, and accessible for our student body.
Keeping each of these machines operating is a balancing act in project management and understanding the level of student demand. In one academic quarter, I expect an average of 80 issues requiring repair for our FDM 3D printers (mostly Prusa Mk3S's). I can diagnose, repair, test, and calibrate these machines quickly and flexibly throughout the week as they go down to keep up with high demand. I also supervise a group of 15 other shop technicians to help fix some of these issues.
One of the responsibilities I most enjoy is working directly with students and professors to help bring their designs to life with more advanced 3D printing. As people reach out to me, I meet with them one-on-one to advise on their designs, assess the feasibility and material selection of their parts, and 3D print them on FDM, SLA, or continuous fiber 3D printers.
I complete SLA 3D printing requests using our Formlabs Form 3 and Form 4. I can print anything from breadboard adapters for students' senior projects to robust hardware mounts for a professor's lab upgrades. It has also provided opportunities to develop my DFM skills for additively manufactured parts.
Interfacing with these groups of passionate students and engineers has been a privilege and learning experience as I play a small part in each of their projects to assist them. I have also used this platform to learn more about additive manufacturing and the many problems and design considerations that an engineer must address in creating a part.
Cal Poly's newest makerspace with the machine shops holds 48 FDM 3D printers for student use, aside from the other eight I manage. The space also contains laser cutters and an embroidery machine. This combination will serve as a widely accessible, no-barrier-for-entry workspace for students interested in digital fabrication.
In my role, I have worked to help develop the space, logistics, and maintenance workflows ahead of launching the space. My main priorities are to increase resource accessibility for students and keep the high level of quality that the machine shops have held thus far.
Developing the infrastructure for the 3D printers, I created multiple accessories and organizers to improve functionality and ease-of-use. The spool holder and filament guide help run filament smoothly into the printers, while the magnetic sign holder allows for swappable displays if the printer is reserved or out of order. The tool holders allows for easily-accessible use of pliers, flush cutters, and IPA.
