3D Printing for Biotechnology and Chemical Sciences- myassignmenthelp

Question: Discuss about the3D Printing for Biotechnology and Chemical Sciences. Answer: Gross, B. C., Erkal, J. L., Lockwood, S. Y., Chen, C., Spence, D. M. (2014). Evaluation of 3D printing and its potential impact on biotechnology and the chemical sciences. Link - https://www.silae.it/files/Anal_Chem_3D.pdf In the paper, the authors talks about the role of 3D printing technology in revolutionizing teaching and research laboratories. In this article the history of 3D printing is talked about, various 3D printing methods are reviewed and additionally it presents current applications. The paper talks about Charles Hull who developed the concepts of 3D printing such as RP (rapid prototyping), AM (additive manufacturing) and SFF (solid freedom technology). Automotive and Aerospace industries have been the beneficiaries of 3D technologies because of printing prototypes of airline and car parts. Additionally, the contribution of this technology government and private defense industry is well recognized. Already the prototypes of gun and various weapons are being produced by the defense industry. In the case of research settings, biomedical and engineering applications have been the contributors in researching about 3D technologies. The main part which the paper focuses is that a branch that is known as chemical sciences has tremendous potential to make use of 3D technologies. This paper also talks about few rapid prototyping methods in 3D technology. SLA (Stereolithography) was developed Chuck Hall. This method was the first rapid prototyping method that was commercialized. Different approaches are used such as laser writing and direct write curing process which is mask based. It also talks about another method which is known as FDM (Fused Deposition modeling) which was developed by Scot Crump. In this method thermoplastic materials are used to produce products. From the paper, it is clear that extensive research was done on methods employed in analytical chemistry to produce prototypes. However, the paper does not include the prospects of future research in the subject. Miko?ajewska, E., Macko, M., Ziarnecki, ?., Sta?czak, S., Kawalec, P., Miko?ajewski, D.

It also mentions that customization of numerous medical devices and cost cutting in manufacturing and design will be brought because of the broader use of 3D technologies. The main objective of the article is to research about existing opportunities in the field of rehabilitation engineering. In this 3D technology, materials like living cells, ceramics and plastics are used to manufacture items. Many technologies or version of 3D technology might be available but the general essence is the same. Any object is built layer by layer in a vertical position. This process allows the creation of complex structures. The paper also mentions that advances in other fields have led to advances in another field. Some of the 3D techniques used in clinical application are 3D scanning and 3D printing in drug fabrication and surgery. It also mentions that manual designing could be changed b ecause of CAD (computer aided designing), RP (rapid prototyping) and CAM (computer aided manufacturing). The strength of the article is that it points out the extensive research already done in the clinical and rehabilitation engineering and also mentions future scope of this technology. The article also points out that there will be emergence of new therapies because of 3D printing. However, what kind of therapies will emerge is not listed. Bibliography: Gross, B. C., Erkal, J.
