While CLIP is definitely an improvement to SLA, it is in no way a consumer printer. That is solely a commercial technology for the time being (next 20 years actually, unless someone finds a way around the patent); the Carbon machine is $40k/year to lease, so that really puts it solely in the price range of commerical operations. You have to be careful differentiating between commerical and consumer technology. A MakerBot is a consumer technology, whereas the Fortus is a commercial machine. Most innovations in the 3D printing industry will be there to benefit the commercial market; a consumer simply won’t pay $5k+ (most will balk at more than $1000) for a printer and that’s not going to change any time soon. Other than that, I’d say material selection and reliability are what are most likely to improve. The filament market has exploded over the last year or so, and as our material knowledge grows, so will the selection of available thermoplastic.
