The question was honestly asked .. I am not a liquid motor specialist … and
was genuinely curious about whether their approach of 3D printing the motor
introduced even more risk.
Although 3D printing seems to simplify some things, I too wonder about
complications due to its use.
One issue that interests me is the effects of surface texture due to 3D
printing.
I know that different surface textures can affect the heat transfer rate. My
understanding is that surface texture affects boundary layer formation. The
surface texture from their 3D printing looks rough and I'm curious as to
whether that would be a help or hindrance. Perhaps it's just something that has
to be accommodated in the design.
Anyone else out there have any idea about the effects of surface roughness on
cooling in an application like this?
