Honestly, resin printers are a god send to the miniatures community. Hands down best tech to print warhammer, n-scale, D&D, you name it.
Someone who's already well steeped in a hobby as demanding as WH40k and who already has access to items they can purchase alternatively probably is not searching for something else they have to get their head around. And MSLA printing is not a chill hobby by any measure.
