Owning a 3D printer can save money on five expensive hobbies
NASA's International Space Station printers make tools, while Earth-based machines offer affordable hobby components.
Entry-level machines cost less than $200
Entry-level 3D printers like the Creality Ender-3 V3 SE start at about $170. More advanced systems reach prices of $700 or more. Most home devices use filament that costs around $20 per kilogram.
Filament types vary by technology
Common printers push plastic filament, usually polylactic acid, through a heated nozzle. More expensive systems use resin or polymer powder for different applications. Some libraries and maker spaces provide access to these machines without ownership.
