Biodegradable 3d printable nanocomposite, bone: This article explores the topic in depth.
In addition,
Biodegradable 3d printable nanocomposite. In addition, bone:
3D printing is now used in routine in certain orthopedic and maxillo-factories surgeries for complex transplants. Therefore, This technology is even revolutionizing the field of reconstructive surgery, thanks to the development of new biomaterials. However, Researchers from the University of Waterloo have just provided additional evidence. Similarly, developing a printable nanocomposite, capable of mimicking the bone structure and promoting regeneration.
This new material is made up of hydroxyapatite nanoparticles. For example, a well -known material from the medical world, since this mineral of the phosphates family is the main component of bones, dentin and dental enamel.
If this material has been used in medical applications since its industrial production in the 1980s. Moreover, the recent democratization of 3D printing technologies initiated the development of materials specific to these processes, including nanocomposites.
Nanostructured nanocomposite based on hydroxyapatitis – Biodegradable 3d printable nanocomposite, bone
According to Doctor Maud biodegradable 3d printable nanocomposite, bone Gorbet. Meanwhile, professor at the University of Waterloo, hydroxyapatitis particles play multiple roles within this nanocomposite, because “They offer mechanical strengthening, making the material more rigid and more solid. They also create a favorable surface for the material to combine with bone cells. »»
In addition. the potential use of materials containing nanostructured hydroxyapatitis for transplants has been confirmed by recent research work[1]bone tissues being able to interact with the graft and gradually replace it.
An ability to printing improved by the addition of Triglyce (TGDA) Diacrylate Diacrylate
Hydroxyapatitis is therefore the ideal material. for custom manufacturing of artificial bones. But to be printable. for example live Ink Writing (DIW), hydroxyapatitis must be associated with organic binders and resins which allow polymerization.
The press release published on the university site does not specify the exact nature of nanocomposite. the binders used by researchers. We only know that the material combines biodegradable 3d printable nanocomposite, bone “A triglyceride similar to fat with a particle to the nanometric scale. called hydroxyapatitis”.
To find out more, you must refer to the recent work of the team led by Doctor Thomas Willett. In a paper published in 2024 in the Journal of the Mechanical Behavior of Biomedical Materials. the researchers explain how the addition of TGDA, a chemical called Triglyce Diacrylate, improves hydrogen links when added to a polyethylene glycol Diacrylate resin, made from egoxy soybean oil.
The process works, but optimizations are still necessary
The researchers managed to prove that it was possible to obtain real artificial bones by 3D printing, with this biodegradable 3d printable nanocomposite, bone material. To be convinced, just watch this video.
In the press release. Thomas Willet said “We can take computed tomography and use computer assisted design to develop a model for the bone piece that must be printed. »»
And he specifies: “We could use this process for any bone that has lost a big piece. has a complex geometry. »»
So much for the feasibility. But for the team. the challenge is now the optimization of the material, in order to find the balance between printability, mechanical properties, sustainability and biodegradation speed.
