Looking forward to seeing how this turns out.
I’ve been considering having a go at printing it my self, at a hacker space... I see how you get on. For whats i be letting my self in for ;)
you'll need about... 10 metres of ABS @ 3.0mm and about 15 metres of PLAY @ 3.0mm. if using 1.75mm adjust accordingly.
What would you need to make it entirely out of PLA?
high-temperature PLA, such as this: http://www.proto-pasta.com/pages/high-temp-pla
the reason is, as i discovered by leaving the first prototype in direct sunlight, that the standard temperature PLA will melt. that means a number of things:
(1) the screen left and right edges bend (2) the screen hinge parts start to deform (3) the friction-hinge softens enough (it's under quite a lot of pressure) so that it deforms and no longer does its job (4) the base back part, which has a circular tube that the friction hinge is in, will crack.
so there is a lot that goes wrong just by having the temperature reach the glass point (60C) of standard temperature PLA.
high-temperature PLA such as that made by proto-pasta is crystalline and has a glass point around 85C.
I would buy a truckload of PLA from the Ingeo plant in Nebraska if I can start making laptops from corn...
cool!
