Via sUASNews, a very cool demo of using a 3D printing pen to rapid prototype (draw!) a quadcopter:
A mate of mine is in purchasing for a leading Australian electronics wholesaler and retailer, who was playing with a test sample of a potential new product.
He was actually building the skeletal frame of a fuselage with integrated tail and seperate main wing using a hand held 3D pen. He did the whole thing free hand against the grid of a cutting mat. The quality and strength was really impressive - easily good enough to fly.
Hand held 3D printers really are more useful than you would expect.
Different perspectives on this device:
Manufacturing Engineer: An Additive Process method employing a very poor positioning control mechanism with almost no chance of reproducibility or statistical criteria for quality control of parts.
Gadget Geek: OMG I gotta get one of those!
7th Grade Teacher (US): Do you know what kind of 'toy' these kids will make with that thing?
Ecologist/Environmentalist: I can see oceans of discarded items polluting our landfills and waterways -- a tragedy!
Game of Drones Guys: I wonder how it takes a paint ball hit?
Stay at Home Mom: Billie! Stop trying to make a Storm Trooper helmet on the cat!
Cat: If I had opposable thumbs, Billie would be in for a surprise.
-=Doug: I think it is a blend of #6, #7, #8 on THIS list.
I wonder if this pen could be used with a simple router pantograph? I have one that I use when I need to make multiples of something in a woodworking project, and can even do 3D routing (to a degree).
This really deserves a 3D printed blog post.
