Can you 3D print titanium bones?

Laser 3D-printing is also widely used for titanium implant manufacturing. The specific features of the process include handling of powders in dangerous conditions (fine powders in the air are explosive) and a required heat-treatment to reduce the high residual stresses.

Is it possible to 3D print bone?

Up to now, 3D bone printing has involved producing material outside the patient’s body. But now a new technique developed at the University of New South Wales in Sydney, Australia, offers the prospect of doctors being able to create new bone tissue exactly where it is needed during a surgical operation.

What are 3D bones?

CT-Bone: real bone from the 3D Printer – CT-Bone is a bone-like customized implant that can be 3D printed and is converted to real bone by the patient. After taking a CT-scan of the patient, a patient-specific implant is designed by our biomedical engineers in collaboration with the surgeon.

What is special about this 3D printed bones?

The 3D printing process has a very high accuracy, resulting in implants that fit perfectly onto the bone of the patient, as designed. Even very complex shapes and designs can be 3D printed; for example 3D printing enables the production of implants with engineered (controlled) porosity, similar to natural bone.

How do 3D printed bones work?

3D printing TCP enables the company to create more porous implants. The porous structures allow the implants to function as scaffolds for blood vessels and natural bone to grow, and the implants degrade over time as they are supplanted by natural bone.

Who invented 3D-printed bones?

Associate Professor Kristopher Kilian who co-developed the breakthrough technology with Dr Roohani says the fact that living cells can be part of the 3D-printed structure, together with its portability, make it a big advance on current state-of-the-art technology.

What is printed titanium?

Titanium (TiAl6V4) is a very strong, lightweight, corrosion-resistant material. It’s printed by sintering titanium powder together with a laser to produce metal parts that are equally as good as machined models. 3D-printed titanium (unpolished) doesn’t look like traditional shiny milled titanium.

What is structure of bone?

Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
