  • My name is Alex Weitman, and I am a junior student at Principia College studying Business Administration and Spanish. I am a collegiate athlete and involved in many extracurriculars. I joined this 3D printing class because I wanted to challenge myself while also getting to learn about 3D printing and being able to print cool objects.
  • Being able to participate in the Open Source movement is really significant because I am able to share information at incredible speeds as well as learn from others and benefit from each other. It is really nice not having to worry about infringing on Copyright laws, but more important than that is that I can be free to share whatever I want, and of course for me, this information will definitely be for the educational benefit of others. I cannot wait until I learn how to create my own designs and share them with the world. When I first began building my printer, I was astounded by how much I was learning in such a small period of time! I felt like I knew so much about 3D printers and how to make something complex on my own. In the future, I will definitely use my printer as often as I can and for the betterment of society if possible, even if in a small way. I may even use it in my future career somehow.
