My conversations with a senior manager for a company that makes
components for auto manufacturers is that, while 3D printing is
widely used for small runs of prototypes, traditional tooling
still rules for production.
In answer to Ed, KL7UW's comments about his amp, I'm quite
satisfied with mine. I didn't notice any real problems with the
holes in chassis.

You can buy a 3D printer for under $5K and make metal work on
an as needed basis. That is where the auto industry is going.

So I chose a good quality commercial chassis from Hammond and
built an aluminum jig to hold it in a vise for drilling.
Square holes required hand filing. Stick-on labeling. I used
a pcb made by a reputable small production house (W6PQL).
Those that bought the 80w 2m amp got a pretty good product but
no confusion that it was hand made. Costs were hard to get
competitive with commercial amp mfrs but I think the
reliability might have been better.
You would have to survey my customers who all read this list
and most have Elecraft radios that were used with the amp
(majority had the KX3-2M).
