I think the first thing that comes to mind when thinking about cross-curricular activities and 3D printing is math. I grew up playing Lego everyday and I now realize that a lot of the building techniques I was using employed math. My younger sister who just started high school, would enter a popsicle bridge building contest all the way through elementary school. Although not directly tied to the numerical side of math engineering structures like bridges is highly mathematical. So using a resource like a 3D printer to create math activities around spatial awareness, measurement, estimation and geometry would be excellent.

Next I think there are a lot of pros (its “cool”, hands on, and uses tech) to using 3D printing as a resource for middle schoolers however, I think a lot of them might find the process daunting or too complicated. I think the end result would be very useful for some learners who gain understanding kinetically and spatially. However, the design process and moral through the creation process would require support and help. In my experience many middle schoolers are often daunted at a seemly large task (that’s not that large) and close their minds to even starting.

I attempted to make a little bridge on tinkerCAD, although admittedly I found the process mentally taxing so I think I would understand the potential feelings from my students. I included pictures below!
