Manufacturing technology
Additive manufacturing’s M 58
edical implants are crucial to modern-day medicine and are used to treat a lot of medical conditions. Additive manufacturing has become one of the most advanced and versatile ways for producing different metal implants, from acetabular cups to stents. Additive manufacturing is highly beneficial for medical implant success because not only can the geometry of the implant be designed and customised to fit the exact space needed, but the surface properties of the implant can also be tailored to improve biocompatibility and osseointegration – which helps the implant stay longer in the body without rejection.
In recent years, additive manufacturing has expanded into other modalities that can print biological materials.
expansion Bioprinting is progressing towards clinical success. Liam Critchley speaks to
Professor Jianfeng Zang of the Huazhong University of Science and Technology to explore how additive manufacturing is transforming tissue engineering and personalised implants.
This is bioprinting and involves the growth of cells to create new tissue and for developing more biocompatible implants. Until recently, a lot of bioprinting has been ex vivo and involved printing implants and structures outside of the body and then performing a procedure to introduce them to the patient. Recent years have seen the development of experimental in vivo and direct-to-body bioprinting techniques, where biological tissues and implants could potentially be printed directly onto or into the body.
The growth of bioprinting
“In traditional additive manufacturing, the biggest application is to help anatomical matching. Based on patient CT/MRI data, 3D printing can fabricate
