Printers: New Source of Cloning Technology?

Imagine the possibility of skipping the doctor’s office for a transplant and going to your own office instead - well, something like that.
“The same kind of machine that turns out documents at the click of a mouse, might some day print out the body part of your choice.”(PopSci)
Scientists are working on a three-dimensional printer, resembling and working much like the printers you have at your desk, except instead of ink in the cartridge, it’s your skin cells.
At first, it was used to make food and even repair a casting of a sculpture. James Yoo, a researcher at Wake Forest University in North Carolina, told the BBC, he and his team are taking it to new heights: repairing the skin of burn victim’s
“…using bioprinting we thought that we could address some of the challenges they’re facing with burn care … what’s unique about this device is that it has a scanner system that can identify the extent and depth of the wound…”
Although it may seem as easy as clicking “print” on your computer, the technology might be further away than around the corner. This video of Dr. Lipton from Golem.de explains why
“There’s still a long way to go before we can take these things and directly implant them into human. There are more animal tests that need to be done. There’s a whole series of steps before this can be compatible commercially as conventional implants.”
And The Washingon Post adds -- researchers also haven’t perfected replication of more complicated bodily structures and organs.
“...the biggest technical challenge for scientists is not making the organ itself, but replicating the intricate internal network of blood vessels, which nourishes it and provides it with oxygen.”
But regardless of the challenges these scientists face, many believe that in roughly 20 years, this technology will be mainstream. And the next step? We could be printing entire bodies.

打印机：克隆技术的新来源？
你看从Newsy多源科技新闻分析。
想象一下，跳绳移植医生的办公室，将自己的办公室，而不是可能性 - 那么，这样的事情。
“同样的机器原来那种在一个鼠标点击文件，可能有些出你身体的一部分天打印选择。”（PopSci）
科学家正在研究一种三维打印机，类似这样的打印机和工作你在你的办公桌除了没有在墨盒中的墨水，多，这是你的皮肤细胞。
起初，它被用来制造食物，甚至修理了一个雕塑铸造。詹姆斯柳，在维克森林大学北卡罗莱纳州的研究人员告诉英国广播公司，他和他的团队正在变成新的高度：皮肤修复烧伤病人的
“...使用bioprinting我们认为我们可以解决的一些挑战，他们正面临着与烧伤护理...最新消息关于这个装置独特之处在于它有一个扫描仪系统，可以识别的程度和深度的伤口...”
尽管它可能看起来像您的计算机上点击“打印”容易，该技术可能会远高于在拐角处。这从Golem.de立顿博士解释了为什么视频
“还有很长的路要走，我们可以把这些东西，直接移植到人类的他们。还有更多的动物实验，需要许多工作要做。有一个步骤，在此之前可以兼容全系列常规植入商业化。“
而Washingon后添加 - 研究人员还没有完善的更复杂的身体结构和器官的复制。
“...科学家的最大技术挑战是不使器官本身，而是复制的错综复杂的血管，它滋养它，并提供它与氧气的内部网络。”
但不管这些科学家面临的挑战，许多人认为，在大约20年来，这一技术将成为主流。而接下来的步骤？我们可以打印整个身体。
