3-D printing 'ink' is way too expensive
3-D printer prices are steadily dropping in an attempt to woo hobbyists, but there's still a costly barrier to mainstream adoption: 3-D printer "ink." Plastic filament, the standard material used by 3-D printers typically ranges in price from $25 to $45 for a kilogram depending on the quality and manufacturer. That's a huge markup over the $2-per-kilogram cost of the plastic pellets used to make the filaments. Manufacturing and research and development account for some of the filament's added cost over the original materials.
