I did a lot of 3D printing and prototyping as well as 3D printing management and maintenance.
What I wish was different
I wish I had more weeks to work at this place because it was my last summer there and the new building was great and they even gave me a personal office I would work in for the time I was there.
Advice
Working with more experienced, and educated engineers is a great opportunity to learn and work with others in the field. I would advise your first job not be a very hard one a nd one where you know you'll be supported as a first-time worker. In other words, your first employer/boss should treat you as a determined worker and a learner because that is very important.
