analyses various current application that are used in 3D printing technology amongst them being tissue scaffolding. The authors further posit that the benefit of 3D bioprinting in the medical research is facilitation of individualized patient care through the printing of patient’s anatomy during surgery. The authors Tasoglu and Utkan in the article “Biprinting for Stem Cell Research”, examines mainly on the bioprinting techniques that are used in stem cell research. These techniques mainly utilize lasers, electricity and acoustics in depositing living cells. They further provide various recommendations on how bioprinting can be integrated in various laboratory techniques in order to provide efficient alternatives to traditional existing methods (Tasoglu and Utkan 12). Such techniques can play an important role in medicine especially in treatment of diseases such as cancer (Tasoglu and Utkan 19). Overview and History of the 3D bioprinting 3D bioprinting was invented in 1980s, when Charles Hull developed the first SLA (stereo lithographic apparatus) machine (Gross et al. 3240). The stereolithography machine is type of printing that involves the use of a UV laser solidifying photopolymer, a liquid with a viscosity and color to make successive layers of materials. This invention was big news to the

The following decade, scientists realized the impact the 3D machine would make in the bioscience industry. In 1999, the Wake Forest Institute for Regenerative Medicine in conjunction with a group led by Atala opened the first lab organ. In the lab, patients would undergo urinary bladder augmentation using a 3-D synthetic scaffold coated with their own cells. In addition, they were able to make a miniature kidney that was able to filter blood in animals and also produce diluted urine. By the mid -2000s, the idea of 3D bioprinting had started to gain shape opening the door to the first 3D machine in 2006. Today, with the development of imaging technologies such as the CT, MRI and ultrasounds, it is very easy to reproduce a 3D digital format of internal organs such as the liver and evaluate them. This innovative technology emerged to address the need of a pre-operative evaluation for organ donors to minimize the risks associated with incompatibility and intraoperative complications during organ transplantation (Ventola 706). Beside using 3D bioprinting for organ transplantation, the Yale School of Medicine in collaboration with the Centre for Engineering Innovation and Design (CEID) is using the technology to create plastic models that help in visualizing fractures and deformities (Phoebe and Alex 8). In addition, the plastic model is used for pre-surgical planning and intraoperative guidance especially in shaping bones grafts during surgery. Around the world now, the 3D bioprinting is now being used in anatomical models that aim at creating functional tissues and organs (Ventolas 706).

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
