[Arm-netbook] libre laptop 3d print run 90% done

[Luke Kenneth Casson Leighton]

holy cow there are *twenty five* separate parts in the laptop's
casework. that's just nuts. if someone had said to me, "yeah you're
gonna be making a 3d printed laptop, you'll need to do it in 25
separate parts" i would have said, "naah, you're having a laugh -
surely it doesn't have to be that complex" which in the past has been
my cue to run like hell from any project whenever someone uses the
phrase "surely it doesn't neeeeeed to be as complex as alll
thaaaat"... :)

anyway i'm nearly done - i just have the touchpanel holder to redo,
and the battery, pcb1 and keyboard tray supports that run off of it.
the parts are all trimmed / adjusted (some details in the join points
are just too small to be able to 3d-print accurately with filament),
so i should be able to begin assembly in a day or so.

fuuun.

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 ;)
For the crowd fund. Will all the laptops be home printed and trimmed or
is there, a mass printing operation that’s done differently from a home
printing? Hows it going to be done?

don't know yet. i'm certainly not going to be doing 250-1000 sets of
3D-printed parts on a single mendel90, i have better things to do than
"explore that space" as the zen buddhists like to put it. last time i
checked there exist online networked 3d printing websites in china
that offer massive discounts due to huge bulk-purchasing of the raw
materials.

thanks again for the updates. ive been reading them! :D

What would you need to make it entirely out of PLA?

I would buy a truckload of PLA from the Ingeo plant in Nebraska if
I can start making laptops from corn...

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.
