Red Bull RB21

The rear brake tin looks 3D printed. Those parts were made in a hurry.

Different material for less or more heat transfer? GP told Max to try a different "test cycle on braking" so they are looking at either getting rears upto temperature or not overheat.

It's the future, actually.

Hurrying is the name of the game.

Its already here in the present additive manufacturing it's currently called

That component although not strictly structural, is heat sensitive and needs construction to mitigate that condition.

It could be the opposite, manufactured in light plastic by 3d print, mould made with that inside by initially spray surfacing, to then cast in something like magnesium alloy by pouring into the mould in displacement of the original structural plastic by melting.

OR metal fused "powder" in matrix construction.

Looks SLS powder printed to me.

Metal printig is ubiquitous allready. And for sure in F1. I bet most if not all of the metal inserts you see in the carbon work is 3D printed.

As for judging from a photo, it is kind of hard to distinguish 3D printed, milled or a cast from a 3D printed plug. Even when holding a part, I've been fooled a few times. Sometimes it is really hard to tell if it is milled and blasted or 3D printed.

3D printing metal is really, really expensive if you need it in "F1 grade". For a cake tin I'd expect it to be speed-milled on a combined mill/lathe machine. It is both faster and cheaper at this scale. It can also be quite a bit lighter as there is more control over the temper af the metal. A printed part is in essence always made from solidified molten metal. With heat treatment this can be improved, but I'd expect a cake-tin to warp too much in heat treatment to obtain the right tolrances.

Good that they addressed the engine cover. Now they have to bring forward the mid-chassis updates and slim down the bulbous nose over the next couple of weeks and make the leading floor area more effective and get more stable downforce there. Then they should be able to trim down the rear wing main plane and static flap angle. The front wing endplates could also be flattened a bit but that could reduce its desired pointiness up front. It looks like the floor is where the focus should be but that takes time.

Edit:
For the one who called this "Complete Nonsense and down-rated", care to explain your logic?
Mine is from an assessment of comparison between the RB21 and VCARB02, which the data shows is a more stable platform.
