well the one im looking at is a dual extruder and will work with either abs or pla.......also have been searching for "upgrade parts". been reading on the many different materials you can "print" with these days......a big THANK YOU to all the members with information on the 3d process. it's been turning the crank in my head for awhile now. not only will it be a toy for me, but it will be used for everyday things. playful and educational, mainly for my mini-me......barely a toddler but he's gonna have a jump start in school
