hi, nice to meet you, my name is Kai, fulltime freelancer.
I am an industrial designer for 8 years in HK. Have studied US for 8 years, obtained an industrial design from Pratt institute, NYC USA.
I think I should be a person you are looking for. I am an industrial designer, studied some art in college, experience work on design, and technology, and last year I just DIY a 3D print, can provide info for secondary school material. (please see portfolio for my 3D printer)
I think of giving a lesson plan that tell the logic of printer work, introduce general building process, explain a role of electric and software components. Giving example of existing 3D design, that I can depict a story from hand sketch idea, CAD modeling, slicing process, and finally printing it from example let say a solid pen case.
I suggest simple software for easy learning such as CURA and TinkerCAD, and they are all opensource free, they are good and easy for beginner experience.
Society impact can tell a story such as Makerbot and Ultimaker, how they grow and create open platform on internet to spread idea and concept around communities. And then come up discussion on future flow in aspect on technology grow. I will also have brief talking on some industrial grade printer. Some of those that I already familiar with from my past work that always needed to print design prototype.
For the millstone and delivery date, can be editable.
please don't hesitate to contact me
thanks
Kai
