Read this article at boing boing and it got me reminiscing about a teenage pocket money spent buying and painting Warhammer minatures.
Crazy with details, these tiny tin & lead (cheaper ones were plastic) characters used to leave me wistfully thinking wouldn’t it be great if they were bigger.
Affordable consumer printers (will always be a niche market I’m sure) can’t be more than 5 years away. What will be the issues surrounding 3d content? I’m immediately thinking of the enormous content of meshes that are available from the likes Daz3d, easily reworked and then sold on for personal download and 3d print and painting. How would copyright be enforced? How many times could you print a figure out, would you be allowed (if a skilful painter) to market them on Ebay?
Would you make your work available for 3d printing? Do you think it could become a viable revenue stream for 3d artist?
