Curious ....
How does one define "a feature"...?
How does one define a acceptable level of quality to define that smallest
feature....?
How many layers of what thickness.....?
I am currently building a project where the client requested 0.001 ... I
suggested a sample at 0.002 and was happier with my part even though it was
sliced at twice the Z thickness or half the number of layers.... It isn't
all about slice thickness or jet/beam size
I think this is a trick question but, an interesting thread
