RE: World's first 3-D printed titanium brake caliper

They clearly just need a LOT more printers.
Actual Lol.Only 128,000 more SLS additive manufacturing tools, and we're there guys. We can print all the calipers for VW group.
But here's the best bit -- the machines will only cost about $13bn to buy too!
It's a steal, I'm telling you.
(I guessed at $100K for the SLS machine based on economies of scale that would also make VW group by far the world's leading tool maker)

Useful. Not!
VAG alone last year made just over 10.3 MILLION cars, each with four brake calipers. So that's a brake caliper off the production line every 0.786 seconds. A 3d printed caliper that takes a multi-million Euro machine several days to make is pointless.
I had a similar conversation recently with a company who is 3d printing heat exchangers (radiators). They said "our heat exchangers are 40% more efficient than the best conventional heat exchanger supplied by any Tier1 supplier today" To which i said "terrific, can i have 1 million of them by the end of the month?" and they said "er, no, they take 8 hours to print". They seemed to be unable to grasp the simple fact that this problem made there "solution" however technically amazing it might be, completely irrelevant......
I am amazed how you flit from open-minded problem-solving enginerd to closed minded, that's how we do it here, old git.

Look where they end up.

Titanium would, of course, be preferable, but utilising the metal has to date been impractical, due to the difficulty of milling or forging components from the aircraft grade material.
But working with the German Laser Zentrum Nord, Bugatti's engineers have apparently found a 21st century solution to the problem. They've designed what is both the first 3-D printed brake caliper and the world's largest functional 3-D printed titanium component...

Bugatti need to buy some newer machines and invest in some more up to date tooling if they are genuinely struggling to mill a bit of Titanium

I guess the point here is that they were able to realise a 3D shape that would not be possible with casting or subtractive manufacturing.E.g. the body of the caliper is not solid but has internal structure.

Exactly this. Additive manufacturing enables you to produce the most optimal shape possible.E.g. the body of the caliper is not solid but has internal structure.
As delta above says, this one is proof of concept.
The thought that you would sell it with holes in that can fill with brake dust, mud, snot etc, would be foolish. However, you could fill it with sodium, or hydraulic fluid which then goes to a cooler.
Liquid cooled brakes - imagine the racing benefits!

I don't THINK that's going to be a big issue on Chirons.TerryFarquit said:

As is often the case with these PR lead announcements, & as an aircraft / spacecraft designer - I don't understand some things.
I don't understand why titanium is better for a calliper than alloy - apart from the bling factor. Aluminium alloy is lighter & conducts heat at least as well. In a calliper, bulk is a good thing as it conducts heat away from the pads, but mass is a bad thing as it's unsprung, so why on earth would you not use the lightest suitable material?
We've been 3d printing Ti for about a decade, so hardly "cutting edge".
If you're going to 3D print a Titanium "something" I would've thought conrods would've been better. Weight only where you need it & internal oilways anywhere you want them - but of course they're not on the outside where the owner can point at them & say "see those - 3D printed titanium they are".
Or am I being cynical?

The Bloodhound SSC steering wheel is made by the same process.
That's been around for at least 4 years IMHO. (and it's bigger)
Nothing new TBH

Forgive my ignorance but why would you not just CNC this for a fraction of the cost?The Bloodhound SSC steering wheel is made by the same process.

It's hollow as well to allow for installation of the buttons and rocket triggers (on the rear of the hand grips) along with the associated wiring.
It sits on a quick release connector with a multipin connector on the back which lines up with the master spline.
So in essence "because we can" if you know what I mean
