Hi, I'm looking to buy a 3D printer for personal use. I have some experience in using one, but zero experience in buying one. I'm currently looking at an Asterid 2000 from Plastic Scribbler for $500. It uses 1.75mm non-proprietary PLA filaments and has a build volume of 8x8x9.5 inch. Can anyone suggest a better 3D printer for a similar price? I would like to keep within this price range but would not mind a more expensive printer if additional features justify the cost. some criteria on the printer: must use non-proprietry filament preferably uses standard 1.75mm filaments preferably able to use more than one kind of filament decent build volume also please list any necessary additional software (besides a CAD program) with your printer recommendation. Thank you!!
