Thanks.

Aren't they slow? I've read of interesting shaped parts taking days to
print.

Not sure what you've heard. Something like the visor bracket would take some time, but not ridiculous amounts like days. For the most part construction time is related to the amount of material required.


I as far as I can tell it takes about an hour to print the visor bracket,
in contract to that I saw some factory with a single injection molding machine is making 5000 similar brackets a day

It seems mostly like a mental exercise, people like to feel they are doing
something


I do understand the intent. Gandhi encouraged Indians to make their own clothing to be free of the industrial might of England. So they bought and used millions of hand powered sewing machines and England got the message.

If enough people were to make them, this could help at the real crunch. But I think we are past that no? Didn't Trump solve the problem by using his DPA stick on 3M? I expect 3M is also making ventilators, tanks and missiles right now to make sure Trump doesn't pull out his DPA stick again.

3M is a lot more afraid of Trump than they would have been of Gandhi. But then aren't we all... aren't we all?

Only in a vacuum.
Easy to imagine hundreds or thousands of people printing one bracket
per hour...

LEGO has a factory here, they converted a few of their machines and are making 13000 visor a day, That factory normally makes ~120million lego bricks a day so if things very really desperate I'm sure they could easily ramp up

I think legos were the inspiration for the science fiction replicator creatures in Star Gate. I wonder what plans LEGO has for so many bricks!!!???

That's a lot of replicators.

You see here, it's clearly true that 1 + 1 = 2. therefore with a little
thought the Riemann hypothesis is also true

The trouble with building a machine that can replicate itself is similar
to the trouble with building a machine that can "think."

Sort of a "systems integration"-problem. Yeah you can make machines that
can do bits and pieces of the tasks of self-replication in isolation, or
neural networks that can do similar things to things the brain does, in
isolation.

But how do you get from there to "The Whole Owl"

For ABS you need a heated bed, and the head needs to be able run slightly
hotter vs PLA. It's a faily common capability or a cheap upgrade.

It's more the volume of the part than the shape.

Seems the affordable 3-D printers are all made in China, but the ASA
filament (UV resistant, outdoors use) is made by at least two different
companies in the USA... FilamentOne and 3DXMAX.

And tips from youtube say that ABS warps during printing if there are
slight air currents, so you have to enclose the print area.
