"Until very recently, 3D printing companies sold only proprietary hardware and materials (including plastic filament) to print with them. "
“直到最近，3D 打印公司只销售专有的硬件和材料（包括塑料耗材）来进行打印。”
This just isn't true. For years 3D printers have been available with or without open hardware, software and consumables. See printer reviews in Make, for say the last three years for examples.

这根本不属实。多年来，3D 打印机无论有没有开放硬件、软件和耗材都可以使用。例如，请参阅《Make》杂志上过去三年中的打印机评论。
