There are drawbacks, of course. The size of products that can be made using a desktop 3D printer is usually limited to something that can fit within a five-inch (12.7cm) cube.
当然，家庭使用的三维打印机也有不足，使用桌面三维打印机制能制作出五立方英寸（12立方厘米）大小的产品；不足工业用三维打印机能够制作的产品尺寸的六分之一。
Early printers were limited. High cost and limited USES meant the 3-d printer market was small.
早期的三维打印机应用范围有限，高昂的成本和有限的应用范围也意味着三维打印机的市场很小。
