c, where the act of listening is free, printing out models costs money. A
box of model soldiers goes for about £20 online, about £25 in the shops – but the plastic to print them out
at home currently costs around £35, and the most common printer – the Makerbot
– costs about £2,000. So an epidemic of piracy seems unlikely. Printing is also
a fairly exacting process – it takes time, effort, and often you get a pile of
goo at the bottom of your machine rather than the thing you wanted. Widespread
physical copying won’t happen, in the same way that photocopiers didn’t lead to
an epidemic of photocopying books.
The technology just isn’t there yet
– even successful prints create models that look like they’ve been left on a
radiator for a few hours. And if it’s not good enough for model soldiers, it’s
certainly not good enough for things with complex moving parts. One engineer
told me: "You have to appreciate how expensive and how specialised most factory
tooling is. You can run a 3D Printer for six months and never make the same
item twice.”
He thought it would be 10 to 15
years before printers able to create factory-quality products would appear, and
those ones able to do in metal would probably never make it into the home. He
did, however, confidently predict being able to print out parts for his BMW on
the factory level ones in a few years’ time, but pointed out that those
machines weren’t going to drop below a million pounds a piece any time soon,
and that even if they did, the materials to make the parts at the right
tolerance for a car were incredibly expensive to buy.
None of the current methods of home
3D printing – the thermal fusing of plastic filaments, using UV light to cut
polymer resin, depositing glue to bind resin powder, cutting and laminating
paper, or even using a laser beam to fuse metal particles – are even close to
reaching the standards a machine would require. It’s all very well to upload
weapon parts to the internet, but without the means to do metal you’ve printed
yourself a cool accessory for your Halloween gangster costume – and if you’re
stupid enough to press the trigger, it’s more likely to take your arm off than
actually fire a bullet.
It strikes me that 3D printing is
the microwave of manufacturing. If you look back at newspapers from the 1970s,
people predicted that microwaves would be the only device in a kitchen, and
that every dish would be microwaved. That never came to pass. Like microwaves,
3D printing will be important, but this isn’t the industrial revolution that
techno-libertarians would have you believe.
A 7 It
seems 3D printing has been spoken and
argued a lot about in the press.
1) True 2) False 3) Not stated
A 8 According
to the founder of Makerbot 3D printing will make copying physical things
possible.
1) True 2) False 3) Not stated
A 9 The
revolutionary technology of the 3D printing will take place in the 21st
century.
1) True 2) False 3) Not stated
A 10 3D printing will definitely encourage
pirating objects.
1) True 2) False 3) Not stated
A 11 The quality of 3D copied
objects is rather doubtful.
1) True 2) False 3) Not stated
A 12 It will take a quarter of a
century to make 3D printing successful.
1) True 2) False 3) Not stated
A 13 3D printing is
technologically so difficult that it will never come home.
1) True 2) False 3) Not stated
A 14 3D is comparable to
microwaving in its history and development.
1) True 2) False 3) Not stated
