3-d implants in the body are no longer a fantasy: a scientific breakthrough from RMIT
A team of bioengineers from RMIT University presented an innovative development that changed the standard approach to 3D printing: a technology for creating ultrathin 3-d scaffolds for implantation into the human body ... According to scientists, the biomedical structure, on which they worked at the dividing time, can become an alternative to real tissues and bones.
The new direction of medical engineering is interconnected with the ability of the human body to heal itself. For example, the restoration of muscles and bone tissue after injury and damage. The main task of the scientists was to design and create a kind of scaffold on a 3-D printer, which is implanted into the body to stimulate the growth of new cells.
The main problem faced by previous studies in a similar area is the manufacture of structures to a minimum size. No one has succeeded in creating biolocation in a size at which the cells could fully take root and develop correctly.
But scientists at RMIT found a new way, printing forms for bioscaffolds with voids and complex patterns, which were filled with a biocompatible substance. As a result of a non-standard approach, the engineers received a frame several millimeters in size, in the cavity of which there is a multifaceted structure. Up to this point, such technological processes were considered impracticable for traditional 3D printers.
The research chief, Catal O'Cornell, said their biotech method is easy to replicate and highly cost-effective.
“When making forms on a typical 3-d printer, we have certain frameworks. But the limited size of the nozzle is offset by the ability to create miniature gaps between the material. Thanks to this, we produce microscopic structures suitable for cell proliferation, ”the scientist noted.
The development caused a stir in the scientific community. But all those involved agreed that the discovery would benefit all of humanity.
