Three-dimensional printers are fast becoming everyday devices in the United States. Three-D printers are used to make everything from automobile parts to bone replacements for human patients. American research scientists are now working on creating replacements for living tissue.

Researchers at the Medical University of South Carolina have been working on creating and manufacturing living tissue since 2003．This process is called biofabrication (生物制造) . It requires special printing equipment and a special kind of ink.

Traditional printers require ink to produce an image or design on a piece of paper. For their three-D printer, the South Carolina researchers prepare complex nutritious solutions they call bio-inks. Bio-inks are made of proteins and glucose (葡萄糖) , which normally provides energy for most cells of the body. The researchers also add living cells taken from the animal that will receive the new, printed tissue. The bio-inks are then added to a device that researchers call the Palmetto bio-printer.

Sarah Grace Dennis is one of the researchers at the Medical University of South Carolina. She says new technology, like the Palmetto bio-printer, is a great help to the biofabrication process.

The bio-inks are placed in three dispensers (分配器) , containers, inside the printer. Lasers control both the position of the printing surface and the places where the bio-ink is released.

Michael Yost is a leader of the research team. He says the printing process is fully automated— machine-operated. He says that the Palmetto bio-printer makes it possible to create complex tissue types.

The researchers say bio-printing is still experimental. But they hope in a few years they may be able to print tissue to replace damaged human organs.

But there are still some problems which need to be solved. Some scientists worry about how to get blood to the replacement tissue. The flow of blood is important to keep the printed tissue alive.

Michael Yost hopes that more people will believe in the benefits of biofabrication.

“Tissue biofabrication is a reality, and it is a reality now, and if you come here and you get to see it. You will get to see it. You can’t touch it, but you will see it and think this is real. And this is really human.”

The easy way out isn't always easiest. I learned that lesson when I decided to treat Doug, my husband of one month, to a special meal. I glanced through my cookbook and chose a menu which included homemade bread. Knowing the bread would take time, I started on it as soon as Doug left for work. As I was not experienced in cooking, I thought if a dozen was good, two dozen would be better, so I doubled everything. As Dong loved oranges, I also opened a can of orange and poured it all into the bowl. Soon there was a sticky dough (面团) covered with ugly yellowish marks. realizing I had been defeated, I put the dough in the rubbish bin outside so I wouldn't have to face Doug laughing at my work, I went on preparing the rest of the meal, and, when Doug got home , we sat down to Cornish chicken with rice . He tried to enjoy the meal but seemed disturbed. Twice he got up and went outside, saying he thought he heard a noise. The third time he left, I went to the windows to see what he was doing. Looking out, I saw Doug standing about three feet from the rubbish bin, holding the lid up with a stick and looking into the container. When I came out of the house, he dropped the stick and explained that there was something alive in out rubbish bin . Picking up the stick again, he held the lid up enough for me to see. I felt cold. But I stepped closer and looked harder. Without doubt it was my work. The hot sun had caused the dough to double in size and the fermenting yeast (酵母)made the surface shake and sigh as though it were breathing. I had to admit what the 'living thing 'was and why it was there. I don't know who was more embarrassed(尴尬)by the whole thing Doug or me.
