it depends on the cost of the laser. sls is great and all, but required a more powerful laser than sla.
honestly, even sls wouldn't find its place in a home because of the mess it would make, however, the peachy printer just made the resin a non issue with a messes.
we will probably know next year which one will be the best, personally i am hoping for sls because the powder would make a wide WIDE range or materials a viable option for prints, and hopefully be cheaper than current markup (50$ a kilo of pls or abs, but pellets are 5$ a kilp)
Of course hardware that a hacker makes would be much cheaper at the same quality than other hardware. That is because the hacker's research & development and patent royalty costs would be nearly zero because they would probably just steal all the intellectual property via reverse engineering and industrial espionage.
And no, if you watch the video you'll know that this isn't flimsy stuff like paper-mache, but something far more durable, resembling wood. Cost of materials is low (and freely available for most people), but the same downside for nearly every 3D printer today: the cost of the printer itself. Still out of reach for most people. But they're working on that. I have confidence that one day it'll be affordable enough. Til then, the Peachy Printer looks like a swell alternative. Hope they succeed.
