The objective of my research project was to better understand the tools used in digital fabrication, and to build a digital tool at LTU to take to Polis University in Albania. Once I received the Presidential Undergraduate Research Award, I began to educate myself on the many different ways I could go about designing a 3 axis computer numerical control (CNC) tool. I conducted a literature search, read digital fabrication blogs, and sought out the expertise of the people around me in the makeLab and professors at LTU.
The design process of the CNC machine began with hand sketching in a notebook, and a digital 3D model using Rhino software. The digital model constantly evolved over the first few months until it reached a point where I could begin prototyping the machine. I started by milling components out of medium density fiber board with hours of cutting, testing, revising, and re-cutting. The time spent prototyping paid off during final production, which went efficiently.
The most difficult task of the research project was figuring out the logistics of actually getting the machine to Albania. It was a constant tug of war between maximizing the cutting power and size of the machine, and also being able to fit within airline restrictions (the only affordable shipping option). The machine also had to be extremely reliable since the availability of replacement parts is close to nonexistent in Albania.
The machine was designed, built, broken down, packed, and flown across the world to Albania for a digital fabrication workshop in the beginning of July 2015. The next 12 days were spent educating students on the machine, going through the computer programs needed to run it, and eventually running the machine. 15 students from both Lawrence Tech, and Polis University ran the machine for more than 30 hours without any problems. The machine was then left in Albania for future students to use.
The research grant turned out to be a twofold learning experience for me. I was able to educate myself, and successfully build an advanced tool that now opens up design opportunities for students in Albania. Facing the challenges of designing, prototyping, and building the machine gave me great respect for the tools we have at Lawrence Tech. The second learning experience was the workshop itself. Watching the Lawrence Tech and Polis University students be introduced to digital fabrication and the amazing projects that came out of the workshop was exciting to see. This research project was invaluable to my education but more importantly, it has helped educate others and will continue to do so.
