Evaluation of 3D Printing and Its Potential Impact on Biotechnology and the Chemical Sciences [1]

Abstract:

Nearing 30 years since its introduction, 3D printing technology is set to revolutionize research and teaching laboratories. This feature encompasses the history of 3D printing, reviews various printing methods, and presents current applications. The authors offer an appraisal of the future direction and impact this technology will have on laboratory settings as 3D printers become more accessible.

This article provides examples, explanations and pro/cons of many 3D printing methods such as SLA(stereolithography), FDM(fused deposition modeling), inkjet, SLS(selective laser sintering), and LOM(laminated object manufacturing).
3D printing hydrated polymers, specifically cells and hydrogels allow for the formation of biodegradable structures onto which living cells may attach and grow.
Stresses the need for biocompatability(being accepted or rejected by the human body) and bioreabsorption(being absorbed by the human body over time) of implanted materials.
Indicates importance of topography(specifically controlled porosity) needs for biological attachment of autogeneous bone growth primarily through calcium based materials.
Utilizing materials such as silicon for support, chondrocytes for biological component, and silver nanoparticles for electronic conductivity, an anatomically correct 3D printed bionic ear was achieved.

-Abstract:
-Renewable energy sources (RES) can undoubtedly contribute to protecting the environment and conserving fossil fuels, as well as enhancing regional and rural development opportunities. However, every energy production process affects the environment and involves the use of land resources. The risks linked to intensified RES use should be adequately taken into consideration in any planning process, as ill-conceived energy policies may adversely impact land and local ecosystems, and lead to increases in public spending. Therefore, before designing any instruments for the regulation of both RES and land-use, the most essential step is to explore investment possibilities in different contexts. This paper intends to locate and quantify the potentials of biomass, wind and solar as well as to explore some of the potential planning issues associated with their development. The methods and findings presented in this paper may help to build a vision for the development of an optimal RES portfolio and to highlight emerging problems associated with RES deployment.
-*Renewable energy sources described take up land. Land - which may be used for farming/biocrops/wind. (Land use demand increases)
-*PV systems have only a small negative impact on ecosystems.
-*PVs need flat land (ideally unsuited to agriculture) as inclined increases costs - forests or other land types make PV adaption more difficult
