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.

In this paper, authors talks about novel technologies such as reverse engineering, 3D
scanning and 3D printing. 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 because 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.
