Three-year-old Dexter Clark was born with bad kidneys. His father Brendan says the boy was constantly sick.
三岁的德克斯特·克拉克出生时就患有严重的肾病，他的父亲布伦丹说孩子经常生病。
When he was 1 year old, we had to have a procedure to give him a gastrostomy, so he could be fed through a tube cause he threw up so much.
当他一岁的时候，我们必须要给他做胃造口手术，这样他就可以通过管子吃东西了，因为他经常吐。
A kidney transplant would change Dexter's life.
肾移植会改变德克斯特的生活。
His father's matched but Brendan's kidney was bigger than average which would complicate surgery,
他父亲和他肾脏是匹配的，但布伦丹的肾脏比平均水平要大，这场手术将会变得更复杂，
so doctors at Guy's and St Thomas' NHS Foundation Trust 3D-printed copies of Brendan's and Dexter's organs.
盖伊和圣托马斯英国医疗机构对布伦丹和德克斯特的器官进行3D打印。
Practicing on the replica organs allows doctors to spot potential problems before the actual operation begins says transplant surgeon Nicos Kessaris.
尼克斯·科萨里斯说，手术之前在复制器官上进行练习，这样可以发现潜在问题。

The components are flexible so you can manipulate them to simulate the steps of the operation as well.
这些零件很灵活，通过操作它们来模拟手术步骤。
Technology company Stratasys developed the 3D organ printer.

These practice organs can help cut the cost of health care says company vice president Phil Reeves.
公司副总裁菲尔·里夫斯说，这些打印器官可以降低医疗费用。
If we can take an hour or two hours off a procedure, if we can reduce the amount of time in that theater,
如果可以减少一两个小时的流程时间，减少手术时间，
reduce the amount of recovery time, the amount of beds being taken up,
减少恢复时间，减少住院时间。
all of that compounded really drives the economic argument for where 3D printing helps the health service.
这些都会引发我们对3D打印如何在经济上帮助医疗服务的讨论。
What's inside? Daddy's kidney. Daddy's kidney? Yeah. And helps a three-year-old boy and his family lead a normal life.
里面有什么? 爸爸的肾，爸爸的肾，帮助三岁孩子和一家人过正常生活。
