“…This material was selected because it has higher thermal shrinkage than other thermoplastic filaments such as polylactic acid (PLA) [37]. The density, glass transition temperature, and thermal expansion coefficient of this material were 1.04 g/cm 3 , 107.8 • C, and 88.2 × 10 −6 / • C, respectively. The initial diameter of the filament was 1.75 mm, and it was extruded through a hot nozzle with 0.4 mm diameter.…”

“…Recent advances in three-dimensional (3D) printing, also known as additive manufacturing (AM), now allow the process to be used not only for conventional prototyping but also for the direct fabrication of functional parts [1][2][3]. Four-dimensional (4D) printing is a unique application of AM that enables the shape of additively manufactured parts to be transformed over time [4].…”

Irreversible and Repeatable Shape Transformation of Additively Manufactured Annular Composite Structures

Four-dimensional (4D) printing is a unique application of additive manufacturing (AM) which enables additional shape transformations over time. Although 4D printing is an interesting and attractive phenomenon, it still faces several challenges before it can be used for practical applications: (i) the manufacturing cost should be competitive, and (ii) the shape transformations must have high dimensional accuracy and repeatability. In this study, an irreversible and repeatable thermoresponsive shape transformation method was developed using a material extrusion type AM process and a plain thermoplastic polymer (ABS) without a shape-memory function. Various types of annular discs were additively manufactured using printing paths programmed along a circular direction, and additional heat treatment was conducted as a thermal stimulus. The programmed circumferential anisotropy led to a unique 2D-to-3D shape transformation in response to the thermal stimulus. To obtain more predictable and repeatable shape transformation, the thermal stimulus was applied while using a geometric constraint. The relevant dimensional accuracy and repeatability of the constrained and unconstrained thermal deformations were compared. The proposed shape transformation method was further applied to AM and to the in situ assembly of a composite frame–membrane structure, where a functional membrane was integrated into a curved 3D frame without any additional assembly procedure.

“…Nowadays the prices of 3D printers are not limited only to prototyping but also to produce the end product, due to the fact that they produce (with the right materials and design) a reliable robust part without many hardware requirements other than the 3D printer itself and the printing material. In addition, 3D printers prices are decreasing sharply in every part of the world [12] . These are the main reasons which made many institutions such as universities to use them in their laboratories and research and development departments.…”

Designing an Integrated Low-cost Electrospinning Device for Nanofibrous Scaffold Fabrication

Electrospinning is a cost-effective technique for synthesizing polymeric fibers with nanometers diameters. Electrospun nanofibers act as ideal scaffolds for tissue engineering and drug delivery systems because they can mimic the functions of native extracellular matrices. However, it is difficult to gathering nanofibers with simple design and reasonable price device. This study presents a cost effective and safe electrospinning system with similar capabilities to standard electrospinning device. As standard current electrospinning system consists of three constructed parts, a hand-constructed electrical power supply to provide a voltage source direct current (DC), a low cost three-dimensional (3D) printed syringe pump and handmade collectors. The device components are entirely constructed off-the-shelf components, and structural elements are 3D printer. The electrospinning process was carried out using PLA materials. The general parameters in the production process are resolution of the spraying rate lL=min and the power supply provides electricity in kilovolt. The prototype is an affordable device; its cost is around 99.5% less than the laboratory commercial devices. The average diameters of the fibers were determined from SEM micrographs with the aid of Image J software, which shows that the electrospinning device successfully produces fibres on a nanometer scale. Henceforth, this project can help educational institutions to have such electrospinning system with ultra-low cost comparing with readymade systems in the market.

“…Then again, this view represents a hobbyist vision of making that can be contrasted with an entrepreneurial one [22,38], which reveals clear connections between making and entrepreneurship. Within the entrepreneurial vision, making is seen to offer a hotbed for innovation [8,11,32], even as a key to entrepreneurship [3,4,22,30] and the maker community having potential to produce new talent for business [8].…”

Digital fabrication, making and entrepreneurship education all have potential to empower children and increase their abilities to participate and shape the society and digitalization within, and act as active "protagonists" instead of passive consumers. While the potential of these educational trends has been acknowledged, they have mostly been studied separately and without specific focus on challenges involved. We have conducted a business innovation project with teenagers at school, combining elements of digital fabrication, making and entrepreneurship education. Our qualitative, data-driven analysis focused on the process and the challenges involved in the endeavor. As a result, we generate a list of lessons learned associated with teenagers adopting the role of a protagonist, driving business innovation. Our main findings relate to the lessons learned on the importance of balancing the making activities with the entrepreneurial aspects and negotiating the roles and responsibilities between the adult participants.
