“…3D printing provides a new creative and innovative platform for almost every discipline in education and research. Particularly, engineering disciplines use 3D printing to make models of new machines, robots, and other prototypes by various software. , It has also been used in automotive and aerospace engineering to prepare prototypes of cars and airplanes and in architecture for printing structural models . In biomedical and health sciences, 3D printing is used for bone grafting, dental implants, and building prosthetics.…”

As an emerging technology, three-dimensional (3D) printing has gained much attention as a rapid prototyping and smallscale manufacturing technology around the world. In the changing scenario of library inclusion, Makerspaces are becoming a part of most public and academic libraries, and 3D printing is one of the technologies included in Makerspaces. Owing to the ease of availability and cost effectiveness, most libraries use fused-deposition-modeling-based 3D printers compatible with plastic printing materials, such as polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS). During the printing, PLA and ABS emit ultrafine particles (UFPs) and volatile organic compounds (VOCs) that may deteriorate the indoor air quality. In this article, first, we have discussed the background of 3D printing, the most common technologies used for 3D printing and printing materials, its applications in chemical education and sciences, as well as 3D printing health and safety concerns. Second, we measured and analyzed the number of UFPs (0.02−1.0 μm) in the 3D printing lab in a library and found that the number of particles/cubic centimeter significantly increased during the printing procedure (36−60 times) and does not return to baseline even 24 h after shutting down the printers. We also provide some recommendations that should be considered when hosting a 3D printing lab in libraries.

In view of the problems of low printing efficiency and low accuracy of 3D printers currently developed in the domestic market, based on fused deposition modeling technology, this paper constructs a processing data model with a cylindrical coordinate data structure by 3D printing and processing models according to the cylindrical coordinate slicing rules. The data model can be used to search in adjacent cylinders to obtain the cylindrical coordinate information of the printing model and use the depth-first traversal method of the slicing model to establish a cylindrical coordinate slicing function. Aiming at the problem of “pointcut” of the model cylinder in cylindrical coordinate slice, a high-performance calculation method of machining accuracy based on the cylindrical coordinate slice algorithm is proposed. This algorithm is used to perform 3D printing processing through high-performance computing of cylindrical coordinate slices. After obtaining the intersection points obtained according to the order of the cylindrical coordinate slices of the model, through the automatic generation of the section profile corresponding to the printed model in OpenGL software, the profile direction of the model section can be determined according to the first cylindrical coordinate slice data generated by cutting each contour. The software and hardware of the 3D printer control system are designed, and the actual model printing test is conducted at the same time. By debugging and testing each module of software and hardware, the system is guaranteed to run stably under scientific and reasonable design. Finally, the experimental analysis results show that the algorithm proposed in this paper can effectively reduce the topology time required for cylindrical coordinate slicing, and the operation is simple, stable, and reliable.

“…Further, 3D printing can facilitate the learning process (Berry et al, 2010;Schelly et al, 2015;Srivastava & Dey, 2018) from active student participation and through cross-curriculum student engagement that can help create a sense of empowerment (Schelly et al, 2015). Also, the adoption of 3D printing provides an opportunity to implement new ways of learning, like experiential learning (Blikstein, 2013;Jaksic, 2014;Kostakis et al, 2015;Pantazis & Priavolou, 2017). Adopting 3D printing has revealed the development of students' practical skills through active experimentation with 3D printing as an integrated part of the learning process (Kostakis et al, 2015;Trust & Maloy, 2017;Srivastava & Dey, 2018).…”

Supplemental Instruction is a program designed to support students in their learning process. The program consists of advanced students supervising new students, where the purpose is to improve students' performance and reduce the risk of interruption of studies. Supplemental Instruction was established almost 50 years ago and is used today in universities around the world. This book is about the role, use and place of digital technologies in supplemental Instruction, which includes why we need Supplemental Instruction, teacher’s integration of technology experience with lecture capture and more. The book is aimed at anyone who is concerned about study quality in higher education. The contributors are researchers and lecturers at various universities from several countries. This book is the first of a trilogy on Supplemental Instruction, where the themes for the other books are " Student Learning Processes" and “Organization and Leadership”. The editors of the trilogy are Abbas Strømmen-Bakhtiar, Roger Helde and Elisabeth Suzen, all three Associate Professors at Nord University, Norway.
