Best and worst 10 Companies that sell 3d Printers?

[LambdaFF]

I own a printrbot and it ticks your boxes. See here : http://3dprintboard.com/forumdisplay...rintrbot-Forum

If you're worried about the quality of the manual, you can fin it here : http://printrbot.com/support/

I'll take a guess and suppose you mean FDM printers only. From what I see I think that other builders are also meeting your criteria, their owners will comment :
Lulzbot
Flashforge Creator
Ultimaker
Hyrel

actually the Lulzbot is one of the best brands i can think of , they have compassion of feedback in all of there feedback , certified open sourced ( software ,hardware ) , and a 30 day money back guarantee and that is one you just can't beat, also the Lulzbot is the most loving and kindness and glow brilliantly even in the darkest times ,

they show the compassion , it's honestly priceless, and that merit sees the same value as you would sponsoring the future over the Canadian seas , and again you can legally modify the 3d printer to your needs
