3D printing for medical.
The researchers for Carnegie Mellon University developed photo-cross-linkable and temperature-sensitive bio-ink for 3D bioprinting.
According to researchers at Carnegie Mellon University in Pittsburgh,¨A new approach to 3D bioprinting has overcome the shortcomings associated with earlier versions of the technology, bringing the creation of human tissue and organs one step closer to reality. Freeform Reversible Embedding of Suspended Hydrogels (FRESH) is an embedded printing approach that solves this problem by extruding bioinks within a yield-stress support bath that holds the bioinks in place until cured.¨
In accordance with co-author Daniel J. Shiwarski, “fabrication technique for [human] tissue engineering and regenerative medicine,” its use has been limited “by the challenge of printing soft … materials in the air.¨
According to Kristof Sehmke, global communication manager at Materialise Medical, told Design News, “We used several medical tools for this procedure. The cutting guides used for this operation allowed surgeons to cut the donor and recipient bones very precisely. We also used drilling guides that allow the donor bones to be attached to the recipient’s bones more easily and with great accuracy. These cutting and drilling guides are prepared virtually based on CT scans and the surgeon’s indications, as part of the pre-surgical planning. The company has a legacy of adhering to the highest possible safety standards and has obtained CE Marking Certification for most of its personalized orthopedic and cranio maxillofacial solutions. This includes 3D-printed anatomical models and patient-matched surgical guides and implants. Materialize was also the first company in the world to receive FDA clearance for software intended for 3D printing anatomical models for diagnostic use. This kind of certification helps raise the industry bar to ensure patient safety and transparency on personalized devices’ production.”
