just because those companies say they worked with 3M for a "special" vinyl doesn't mean they did. In the case of dbrand they just switched from di-noc to 1080/2080 for the Nintendo Switch.
UV tends to shrink and leave cause air pockets under these materials, far better to print with solvent and laminate. I've been making skins for phones and video game consoles for years, including thousands of printed laptop skins for various large companies.
It'd be dumb for them not to have. Our 3m rep has just spent weeks researching and sending vinyl to their testing facility and is testing various inks and weatherproofing them / getting a life cycle out of it for us, and that's just their latest project they're working on for us.
Dbrands issue was not just going from dinoc to 1080/2080. Dbrands was not the only company having issues with switches plastic getting damaged, and it was mainly on their printed vinyl... Which dinoc doesn't have a printed?? So not sure why you think that was their solution.
My guess is they ended up using a lower tac glue such as 3ms changeable films. 3m will custom make products if you order it in enough, so for all we.know they're using 2080 vinyl with low tac adhesive.
And that's the problem. Getting into a market.you know nothing about. If op sold a paltry 20 skins to switch users and then found out a month later the $50 he made just caused $6000 in damage... Is it worth it?
