3D printers are hailed as the next revolutionary technology, yet few scholars have studied whether 3D printing will decrease poverty and inequality. This paper determines the availability and accessibility of 3D printing technology in low-income communities through public libraries and gives insights on how libraries use 3D printers. By examining the 2013 Digital Inclusion Survey and conducting interviews, we found that libraries are quickly acquiring 3D printers; however, the technology is not being fully adopted by the patrons due to the lack of training, software and practical applications of the technology. Also, we found out that the cost to use a 3D printer in public libraries is relatively low, and does not prevent patrons from accessing the technology. Overall, we believe that libraries will only play a small role in providing availability and accessibility to 3D printing technology for marginalized communities.

Using 3D printing technology in learning institutions brings an industrial experience to learners as well as an exposure to the same cutting-edge technologies encountered in real life careers. The chapter explores 3D printing technology at kindergarten (preschool), in the lecture room (BEng programme), and ready-to-use 3D printed products. In educational toy applications, the effect of poor product designs that do not meet the children's dimensional and safety requirements can lead to injuries, development of musculoskeletal disorders and health problems, some of which may be experienced by the children when they grow up. In order to address the problem of poor design, measurements of anthropometric dimensions from male and female children, aging from 6 to 7 years old were taken and concepts for educational toys were then generated. Other practical applications of the 3D printing technology explored in the chapter are lecture room demonstrations, prototyping of design projects and a web-based mass-customization of office mini-storage products.

The confluence of three-dimensional printing, three-dimensional scanning, and the Internet will erode the dividing line between the physical and the digital worlds and will bring millions of laypeople into intimate contact with the full spectrum of intellectual property laws. One of the areas most affected by 3D printers will be three-dimensional art. This Article analyzes several ways in which 3D printing technology will affect the creation, delivery, and consumption of art. Not only does 3D printing offer great promise for creative works, but it also presents a problem of piracy that may accompany the digitization of three-dimensional works. As 3D printing technology’s relationship to intellectual property law is largely unexplored, this Article explores foundational issues regarding how copyright law applies to 3D printing technology, laying the groundwork upon which further analysis of 3D printing’s effects on copyright law may be built.

For 3D printing technology to be used at the manufacturing site, excellent 3D printers, materials, and software are essential. Moreover, in the additive manufacturing (AM) process, software simulation is becoming more important as materials are diversified, and output shapes are more complicated and larger. The goal of the AM process simulation is to prevent build-up failures by predicting the macroscopic distortion and stress of the part. In the AM process simulation, structural deflection or thermal deformation easily occurs in the case where the shape of the additive manufacturing products is large and complex. So, it is necessary to provide more optimized parameters for the build-up process and more precise production of supporters. This chapter is an example of applying AM process simulation to industrial and medical parts to produce excellent products.

The emerging 3D printing technology has the potential to transform manufacturing customized optical elements, which currently heavily relies on the time-consuming and costly polishing and grinding processes. However, the inherent speed-accuracy trade-off seriously constraints the practical applications of 3D printing technology in optical realm. In addressing this issue, here, we report a new method featuring a significantly faster fabrication speed, at 24.54 mm3/h, without compromising the fabrication accuracy or surface finish required to 3D-print customized optical components. We demonstrated a high-speed 3D printing process with deep subwavelength (sub-10 nm) surface roughness by employing the projection micro-stereolithography process and the synergistic effects from the grayscale photopolymerization and the meniscus equilibrium post-curing methods. Fabricating a customized aspheric lens with 5 mm in height and 3 mm in diameter could be accomplished in less than four hours. The 3D-printed singlet aspheric lens demonstrated a maximal imaging resolution of 2.19 μm with low field distortion less than 0.13% across a 2-mm field of view. This work demonstrates the potential of 3D printing for rapid manufacturing of optical components.

Abstract Propagation of elastic waves along a direction has special interests in practical applications. These concerns generate the design of an elastic wave metamaterial with electrically switchable properties, which is studied in this work. The structure contains a T-shaped waveguide in a plate with the 3D printing technology; and the active control system is used to tune the propagation direction of the flexural wave. The piezoelectric patches which are connected by the negative capacitance circuits are applied to behave as the active control system. The finite element simulation is performed to give the theoretical prediction of the switchable waveguide and the tunable equivalent parameters are achieved by the electrical circuits. The active control experiments are finally carried out to support the numerical design.

The pharmaceutical industry is set to join the fourth industrial revolution with the 3D printing of medicines. The application of 3D printers in compounding pharmacies will turn them into digital pharmacies, wrapping up the telemedicine care cycle and definitively modifying the pharmacotherapeutic treatment of patients. Fused deposition modeling 3D printing technology melts extruded drug-loaded filaments into any dosage form; and allows the obtainment of flexible dosages with different shapes, multiple active pharmaceutical ingredients and modulated drug release kinetics—in other words, offering customized medicine. This work aimed to present an update on this technology, discussing its challenges. The co-participation of the pharmaceutical industry and compounding pharmacies seems to be the best way to turn this technology into reality. The pharmaceutical industry can produce drug-loaded filaments on a large scale with the necessary quality and safety guarantees; while digital pharmacies can transform the filaments into personalized medicine according to specific prescriptions. For this to occur, adaptations in commercial 3D printers will need to meet health requirements for drug products preparation, and it will be necessary to make advances in regulatory gaps and discussions on patent protection. Thus, despite the conservatism of the sector, 3D drug printing has the potential to become the biggest technological leap ever seen in the pharmaceutical segment, and according to the most optimistic prognostics, it will soon be within reach.

With the rapid development of 3D printing technology, 3D printers are manufactured based on the principle of 3D printing technology are more and more widely used in the manufacturing industry. Choosing high quality 3D printers for industrial production is of great significance to the economic growth of enterprises. In fact, it is difficult to select the most optimal 3D printers under a single and simple standard. Therefore, this paper establishes the probabilistic double hierarchy linguistic EDAS (PDHL-EDAS) method for the multiple attribute group decision making (MAGDM). Then the CRITIC model is introduced to derive objective weight and the cumulative prospect theory is leaded into obtain the cumulative weight of PDHLTS. In addition, what’s more, the PDHL-EDAS method is built and applied to the choice of high-quality 3D printer. Finally, compared with the available MAGDM methods under PDHLTS, the built method is proved to be scientific and effective.
