Design for Manufacturability paradigms sometimes generate odd choices that only make sense in certain use-cases. When scaling up to over 50k pcs/month the incremental costs do get ugly fast.

However, for many of the same reasons a 3k USD PLC makes sense in many low volume long-tale market applications (i.e. pre-certified and stamped hardware.)

Best of luck, =3

The Formlabs Form 4 uses a CM AFAIK and at a 4-5k price point it's not hard to see how they sell them at a profit.
