We experimented with ironing, but you can't see it in those views. The A1 is a pretty good printer OOTB. There were a few iterations on the case design though to optimise the edges.

what's the solution here? vllm?

https://www.firetruckmall.com/AvailableTruck/10923/2018-Neot... this would seem to be the source, is it a test? but why would you use a real quadbike in freezing water for a test? Looks terrifying.

We also released some of the data as a free dataset with a commercial option for all of it. This was more successful than I thought it would be and was hoovered up by the kind of people that buy these datasets.

It will have been surpassed by recent developments now but it was an incredibly enjoyable project.

but...liquid propellents are either pretty dangerous (hydrazine et al), or impossible for an amateur to work with (cryo requirements, pressures required, complex starting sequence etc).

The plumbing, extra parts, materials required, tolerances mean that what you might consider as a "classic" liquid design ends up being pretty heavy at a small scale, so you have to build a bigger engine to cope with the extra weight. So you would end up with an engine not really that analogous to what you would consider "classic" liquid designs (gas generators/tap-offs/staged combustions).

However.... Frank Malina and Jack Parsons essentially did what you're proposing in the 1930s without any new fangled 3d printing technology, so it's possible! Just don't end up like Jack Parsons.

There's a dataset that would help there.

Anyone come across such a thing?
