3D bioprinting in healthcare: This technology can eliminate the need for invasive surgeries
Healthy pets could be passing on multidrug-resistant organisms to owners: Study
"Current 3D bioprinting techniques need the creation of biomaterials outside the body, and implanting those into a human would often require big open-field surgical surgery, which increases the risk of infection," said Thanh Nho Do, a biomedical engineer at UNSW Sydney who spoke to Freethink.
How do 3D bioprinters function?
Aside from printing bioinks, the soft robot can function as an endoscope, electric scalpel, and water dispenser. Researchers have tested these functions in an artificial colon and a pigs intestine and kidney.
Before considering human trials, scientists will have to conduct in vivo testing on animals. If everything goes as planned, they anticipate that the bot will be ready for clinical use in fiveto sevenyears.

Once put into the colon, the robot may remove a difficult-to-reach tumour and then 3D bioprint material to promote healing on-site. If the robot passes development, clinicians may be able to use it to treat colorectal cancer, which is the second most common cause of cancer deaths, reported Freethink.
