Artificial Cartilage Generated With 3D Printer

Cartilage is an essential body structure that has the consistency of plastic and amazing properties like being able to bear weight, but yet be much more flexible than bone. Unlike bone, it does not contain any blood vessel or nerves, which makes it a prime target for artificial replacements.

A team at North Carolina’s Wake Forest Institute for Regenerative Medicine has developed a way to print a cartilage replacement, using a 3D printer. We have previously reported on heart growth, printed human tissue, or even printed prosthetic teeth, but this particular technique creates a polymer porous structure on which the body can grow natural cartilage.

At the moment, the test subjects were mice, but according to the researchers the technique works and it has potential for use in patients.

Hybrid 3D printer could fasttrack implantable cartilage

Most of the attention surrounding 3D printers in medicine has focused on patching up our outsides, whether it’s making skin to heal wounds or restoring the use of limbs. The Wake Forest Institute for Regenerative Medicine has just detailed a technique that could go considerably deeper. By mixing natural gel put through an inkjet printer with thin and porous polymer threads coming from an electrospinner, researchers have generated constructs that could be ideal for cartilage implants: they encourage cell growth in and around an implant while remaining durable enough to survive real-world abuse. Early tests have been confined to the lab, but the institute pictures a day when doctors can scan a body part to produce an implant that’s a good match. If the method is ultimately refined for hospital use, patients could recover from joint injuries faster or more completely — and 3D printers could become that much more integral to health care.
