Does anyone know if teams are already using this in F1 ?
I can imagine it being useful for a compact packaging and chassis design to save weight (e.g. thinking back of the Sauber C32 in 2013 with the extremely small sidepods).
I love additive manufacturing, but having worked with it for many years I am less bullish.wgknestrick wrote: ↑Mon Oct 23, 2017 3:43 amVideo didn't work, but I can speculate what (iterative) tech you are referencing...
It only gets you so far (mainly for homogeneous materials), and IMO, the teams are well past that and onto algorithm based lattice structures via 3D printing. 3D printing is absolutely the future of F1 with respect to optimizing designs and creativity with microstructures. It basically removes all limits of manufacturing except general constraint of SLS process is about a .028-.030in min feature size, dia strut or lattice. You can print functional heatpipes, mechanisms, heat exchanger cores, mass dampers, oil passages, filters, baffles, etc right inside a solid exterior part......and no one would ever know it's in there (hint hint). Not to mention how easy it is to design incredibly strong joining structures to CF or overmold the 3d printed parts. If F1 is allowed per regs, they are probably 3D printing a metal part.
I work with this kind of tech in the medical implant field and you cannot believe how strong (and light) these structures are in Ti SLS material.

Some sort of HE core...maybe an F1 intercooler

This software (or their own custom versions) is where most teams are probably working now. Machine learning certainly has it's place in F1 though. Strategies, fuel/ harvesting mapping, etc. With F1, if it exists and can give them ANY advantage, just assume they are using it.

The complexity of the lattices quickly outpace the limitations of modern CAD software and you need to separately mesh your CAD designs in a post processing step to ready the STL files for printing.

So far, it does not really make sense to let a computer do it. The CAD systems used to generate such surfaces will require some human input. You can setup algorithms to change certain parameters but it will not design something like this from scratch. A surface designer will have generated such a surface in ca. 2 days.
3D printed parts are very common in F1. Mainly for wind tunnel testing but also race car parts are done by this. Some can even be spotted if you look carefully.
