Conclusions: We conclude that 3D printing techniques are practical and anatomically accurate methods of producing patient-specific models for surgical planning, simulation and training, tissue-engineered implants, and secondary devices.
Expansion of this technology may, therefore, contribute to advancing the neurosurgical field from several standpoints. This technique has enabled the fabrication of physical, 3D models from computer-aided designs through additive manufacturing, in which successive layers of material are deposited onto underlying layers to construct 3D objects.
Several methods of printing have been developed that leverage unique material properties to selectively cure or fix specific areas on an individual layer. Most notably, fused deposition modeling utilizes a thermoplastic material that hardens after being heated during extrusion, whereas stereolithography SLA employs a low-power ultraviolet UV laser to solidify a liquid photosensitive polymer.
Within the last decade, applications for 3D printing technology have expanded greatly in the manufacturing industry as a result of numerous innovations that have markedly reduced production and technology costs, improved the level of accuracy of printed objects, and increased the range of printable materials.
These improvements have provided the capabilities to create a variety of products and even make this technology available to consumers for in-home use. Applications within clinical medicine are also emerging due to 3D printing's ability to produce individualized models, devices, and implants that can potentially improve patient care.

The field of neurosurgery, in particular, has experienced substantial progress as a result of the usage of 3D printing. Because most of the surgical procedures and corresponding pathology that neurosurgeons encounter involve intricate, minute anatomical structures that cannot be outwardly observed, neuroimaging has become an integral component of clinical practice. With this technology, anatomical structures can be reconstructed from 3D volumes and subsequently fabricated as physical models, which can then be used for surgical planning and education for both patients and trainees.
Similarly, the capabilities of 3D printing can be applied to the design of surgical simulations. Simulations provide a realistic representation of the surgical procedure without the risk of potential harm to a patient.
This application may enable surgeons and researchers to create instruments and implants that correspond to individual patient anatomy for a personalized approach to treatment. Because of recent advancements, biological materials can additionally be utilized as a printing medium to construct engineered, inert scaffolds that can be populated with patient cells for the purpose of transplantation.
Studies involving the incorporation of 3D printing in neurosurgery have focused upon three main areas, i. In this article, we will review these studies within each subspecialty area within neurosurgery to assess the progress of the field. Three medical databases Compendex, Scopus, PubMed were searched using keywords for relevant literature between database inception to December With product designs increasingly distributed through online file sharing, consumers have somewhat transformed their identities into producers and designers, and as such democratizing manufacturing.
People need not subscribe as readily to the consumer culture of purchasing commodities when they are able to produce everyday commodities such as utensils and apparels with their 3D printers.

All that these people will need to purchase are the materials required in such production. Prosumerism, a term coined by Toffler , is an idea that the consumer is also a producer who is actively engaged in the production of commodities.
Though Toffler coined this term to apply to the Internet, whereby users are also seen as cultural producers of ideas, music, images etc. As such, this technological design is likely to shape market-consumer relations to become more democratic.
This is similar to the USA Patriot Act implemented in that legalized wiretapping and increased surveillance by the state on its people, in the name of countering the dangers of terrorism. As such, the 3D printing technology is inherently political because the nature of this technology requires regulation and manufacturing security in order to avoid the creation of harmful products that may be disruptive to society Pierrakakis et al.

Therefore, it can be argued that the nature of 3D printing technology is political as the widespread implementation of this technology is likely to result in countermeasures that may enable the state to exert more control over its citizens, even into their private spaces.
With the rise of developing countries like China as manufacturing powerhouses of cheap mass production of commodities, manufacturing industries in the developed nations have been symbolically and economically affected. With the shrinking reliance on imports from China, the economic decline that China experiences can have the symbolic effect of stunting her status as a rising economic and military superpower, thereby ensuring the dominance of Western powers over the Dragon of the East.
Therefore, the 3D printing technology can be argued to be inherently political in both an economic and symbolic sense as it serves to restore the hierarchical order between Western nations and Eastern ones, particularly China. All technologies are never neutral; they are political, be it in design or by nature. Though democratic in production, this technology can also bring about undemocratic repercussions due to its nature which is requiring of some forms of state regulation to prevent the production of harmful products in society.
Also, the political aspects have been highlighted in how the technology can alter social relations between the worker and the employer by dispensing with the reliance on skilled labour, as well as between the market and consumers by transforming the identity of consumers into prosumers.
The symbolic political aspect of the 3D printing technology, though not as apparent, can also be seen in how this technology can be used to restore hierarchical orders among nations. As the 3D printing technology is still relatively new having only been introduced towards the end of the 20th century and only rapidly developed in the past decade, this technology is yet to be widely adopted in public spheres of productions and thus many effects of this technology are unlikely to be observable in society at present and can only be predicted or speculated.
Hence, much of what has been discussed in this essay regarding the politics of this technology remains predictive rather than empirically observed.
However, there is no doubting the fact that the 3D printing technology has the ability to powerfully transform human ends to adopt to these technical means when this technology does develop into a production system that is large-scale enough to displace traditional manufacturing systems in the coming decades or even years. Herein lies the political characteristics of the 3D printing technology.

Without support during the build there would not be a successful outcome. The printer nozzles extrude the binder in liquid form similar to a regular 2D inkjet printer. What this does is render the finished item stronger and more stable. Therefore, this development has the political consequences of wresting power from the workers and redistributing it into the hands of the factory owners.
