Ok, so I see you can buy 3D Printer Filament for about $40 or so. My question is, how far does 1 KG go? Can anyone put it into words for me? Will 1 KG Filament last only a few small prints, or will it last dozens? What are your experiences? Like for instance how many grams are used to print something like an iPhone case, or something like a plastic bottle? Just trying to get my mind wrapped around what the costs will be when my printer comes. I see a ton of negative comments from bloggers and tech sites about the costs of printing. Has me a little worried that I may be getting into a hobby I can not afford.
