To me the big issue is the creation of the art for the models.
I have fully mastered 2D artwork that I use with my laser cutter to cut parts for models. I even sold a few at one time.
When 3D printers started to hit the market I got some 3D software and tried to 'draw' some VERY simple parts.......I failed.
If I had spent more time....maybe....but the time it would take means less time with my classic cars, models and trains that eat all my time now.
Some will and have mastered it very well.....but I do not think the average guy will master creating artwork AS WE KNOW IT TODAY.
That too will change someday.
