TOMSK,
Feb 27 – RIA Tomsk. Scientists of Tomsk Polytechnic University (TPU) together with
colleagues from Mid Sweden University create alloys for 3D-printing of artificial
limbs by individual standards of patients, and also coverings which help an
organism to accept implants easier, the chief of TPU Technology Center Roman
Surmenev reported to RIA Tomsk.
"Works on 3D-prototyping we conduct with Mid Sweden University, our
collaboration consists in development and carrying out basic researches on new
alloys for medical use. Our Swedish colleagues have the installation and
technology for the printing", – Surmenev told.
He explained that 3D-printing technologies allow to create implants on pictures
of a three-dimensional tomography, which will be the exact copy of the lost
site of a bone. However the exact form of an artificial limb doesn't guarantee
that it will be ideal for the person. The essence of work of polytechnicians is
in developing of "palette" of materials with various properties.

"For each clinical case we can receive an individual implant – the size,
structure, roughnesses, weight … To each person – their own material. If we're
talking about a teenager, then one characteristics are required, if for the
adult - here are other sizes, weight of the person, and loads", – the
interlocutor of the agency noted.
According to him, printed implants can be used for replacement or treatment of
any site of a bone tissue: at skull injuries, in maxillofacial surgery,
prosthetics of coxofemoral or small joints or in any other case. TPU scientists
conduct researches within the framework of the project of the Russian
scientific fund.
The scientist added that inorganic coverings are also developed. They will
"hide" distinctions between material of an implant and a bone tissue,
thanks to what the risk of rejection of artificial limbs will decrease.
