3D Printed Glasses

In desparation I had to save mum! - She has very strong glasses and broke them again...  So my sister posted her glasses to me and I had to make a few pairs with spares quickly!  Nothing electronic, just functional glasses to get mum out of a bind...  She's gonna look a little silly for a few days while she waits for "proper glasses", but at least she can see :-)

Designing and making 3D Printed Glasses

I say this every time you post a new article or video, but once again, Howard, you've outdone yourself! Super cool video, and near to see the entire process. You mentioned the sizing initially being a bit off. What, if any, were the biggest challenges you encountered during the process of 3D printing these glasses and how did you manage to overcome them?

Hi Moe, thanks for your kind words!!...  The challenge of copying the shape of the lense and then scaling required 3 or 4 print itterations which made the process painfully slow.  Now, if only someone could wire-up some kind of optical 3d scanning device to create a solid model of the lens, this whole process could be slicker and possibly productionised for those in desperate need or who have old lenses that work in broken frames.  I wonder if there is a clever person out there who has seen/experience of making a scanner :-)

That definitely sounds challenging! And what you mention about a 3D scanning device for creating a solid model definitely sounds like a potential game-changer. That might be a neat means of allowing for print-on-demand production. I'm keen to see if/when that begins to take off!
