I might agree with you if I hadn’t heard ten thousand bad takes over the years about how digital art isn’t art or how photographs aren’t art or how video games aren’t art. If their take was that printing pre-made files isn’t art, then they should have said that.
They kind of did though, as they’re specifically comparing the printing process with the carving/sculpting process with no mention of the creative aspects such as 3d modelling for the printer vs. planning out what you’re going to sculpt.
Seems like you’re taking it a little personally and twisting words tbh.
