Don't "buck" / "book" and "luck" / "look" sound exactly the same? They're homophones.

Only in (I’m ste with English accents...) Birmingham!?

Well I'm approx 7 miles from Manchester City Centre and no one in these parts would say those pairs of words any differently.

3D printing... I just don't get it.

I keep hearing how eventually anything and everything will be able to be 3D printed in your own home, from clothes to car parts to medication, but from all I've seen 3D printing just consists of creating something out of plastic that the 3D printing machine cuts/shaves down to shape.

How can an infinite number of items made from an infinite number of materials all potentially be ''3D printed''

As Londoners, the correct way that my sons and I would say it would rhyme with buck or luck, Northerners I always found, said it to rhyme with book or cook, and I don’t mean book to sound like buhk, or cook to be coo- then keh.
It’s not easy to do phonetics when typing, gimme a break.

Don't "buck" / "book" and "luck" / "look" sound exactly the same? They're homophones.
I think I might understand - it's the proper full-on 'u' sound that probably sounds severe to your ears.

No. Buck rhymes with luck and book with look. I've known people to rhyme book and look with Luke, but not with luck.

A 3D printing machine doesn’t actually cut or shave, it either lays material down in layers or fuses the output within a pile of material. Whilst it’s often used for plastics, you can also 3D print ceramics and metals.

Ah right, i didn't realise it was actually creating the material rather than just shaving down a block of raw material.

It still seems a bit far fetched when I hear people saying entire products consisting of multiple different materials could all be 3D printed from the comfort of your own home,they're practically talking about a Star Trek replicator!

No. Book, look, buck and luck are all pronounced exactly the same!

How does the Queen swear, that's all you need to know? Just listen to a Suvverner, that's how to swear.

The long A, and the 'you' sound, not the 'oo' sound.

Can anyone give a short master class in phonetics, please?

Lots of people in that area pronounce luck and book with a long vowel but fk and duck with a short vowel

And trèfle is clover which makes sense. But the word "Clubs" doesn't. Lost in time perhaps. Ah well.

The English name "Clubs" is derived from the suit of Bastoni in Italian-Spanish suited cards.

Serious question. If you say to someone "Good luck" you pronounce it "Good look"?
Isn't that a little confusing?

The printer doesn't cut or shave, that's machining.

The printer has a spool of material and prints the component in layers from a 3D drawing. It can even print moving parts in situ.

3D printers are available from a few hundred pounds, and loads of 3D files are available on the net.

They are incredible when you watch them printing something, but why do they all look like they have been knocked up in a shed?

Would you pronounce fluke the same way? That's the only variation on book/look pronunciation I've heard (Brummies), but they wouldn't pronounce buck/luck the same.

A lot of them are. And, it seems, the first few projects that people print on their 3D printers are parts to make their 3D printers better, which you'd think the manufacturer would pick up on and include, for a few extra quid. I suspect we're talking about low-end "hobby" 3D printers rather than proper industrial-scale ones, though.

I've never seen a real full-scale one, and I imagine it will have a lot more covers and shields than you normally see on a low-end one - both for safety, and to reduce dust / contamination. And of course when you have one on an exhibition stand or in a video, that's usually to demonstrate how it builds the workpiece up in small layers, and that's the fascinating bit - so you don't want it covered up in that scenario.

They really aren't.

We have a Rapid department, size of a medium sized warehouse, with multi-million pound machines. We can print intake manifolds in metals that can be directly used. They don't need stuff to be made out of SLS to make them "better"

The beauty of 3D printing, and its greatest potential, is for manufacturing spare parts that can no longer be obtained.

In the not too distant future, you might find that you need a special kind of widget to repair something and the company no longer exists (or no longer makes parts) but the 3D Printing file needed to manufacture the part it is still available on the internet.

Right now I don't think we're quite there yet. Home 3D printers are probably analogous to dot matrix printers of old, but just like you can now buy a colour laser printer for home use, one day you'll be able to buy the equivalent 3D printer for home use.

One thing you can do right now though is manufacture small hobby parts. For example, Peter Sripol has a video on how to make a remote control paper aeroplane using a cheap inexpensive drone. For best results, you need a specialist plastic part to mount the motors which he makes available as a file for those with a 3D printer.
