“…Three-dimensional (3D) printing means a form of technology that can produce concrete objects by adding material layer by layer in accordance with a sliced digital model of this object [22,23]. 3D printing is also referred to as additive manufacturing (AM) when any industrial use of it is discussed [8].…”

3D printing is a solid part of the health care environment, and in the future, it could assume a more innovative role in the work carried out by practical nurses. However, the educational context may not support the preparedness to face and adapt new and creative technologies on the part of practical nursing students. This study aimed to describe practical nursing students’ technological acceptance towards 3D printing before and after six hours of 3D printing instruction. The technological acceptance model was used as a framework of the study. The data was collected using focus group interviews that 14 practical nursing students participated in before and after their six-hour 3D teaching course. Along with the thematic analysis, the interview themes were created in accordance with the theoretical elements concerned. The results showed four narrative themes that described how a six-hour lesson series changed the students’ technological acceptance towards 3D printing, from: 1) professional meaningless to everyday usefulness, 2) resource dominance to a part of working life, 3) special competence to ease of use, and 4) assumptions to limitless possibilities. Every theme consisted of two subthemes. Despite having been a new thing for students, 3D printing could be conceived in terms of having professional significance. The students described 3D printing as being easy to adapt to and they highlighted the meaning of its educational usage, as it could prepare them to be better with respect to applying creative working life-based technological solutions. As a conclusion, it can be stated that even short educational sessions can promote practical nursing students’ technological acceptance towards 3D technology and the know-how to implement it in working life. This requires educational institutions to target resources to 3D printing and on teacher education.

“…However, it was not until the last decade when 3D printers became more accessible and, hence more popular [1]. During this time, researchers and educators agreed that considering 3D printers in their fields is very positive due to their versatility and benefits [2][3][4][5][6]. One example of this issue is the consideration of this technology by the education community for incorporating new technologies in science, technology, engineering and mathematics syllabus [7][8][9].…”

This work shows the redesign of an elemental experience based on the Helmholtz resonator using 3D printing. A Helmholtz resonator is based on a volume and at least one opening that can include a tube or not. The air column inside the tube can be considered the mass of the system, whereas the volume represents the system's stiffness. Due to these analogies between acoustics and mechanics, the Helmholtz resonator is an interesting example of a harmonic oscillator. The relevance of harmonic motions is well known, and this topic is present in the syllabus of many technical and scientific education degrees. In this work, a bottle has been designed and fabricated using 3D printer technology. The design aimed to create a Helmholtz resonator with a variable frequency of resonance. Different mouthpieces have also been designed. The bottle is composed of a set of cylindrical sections that can be attached, enlarging the length of the container. For ensuring that the different parts set a tight enclosure, an O-ring seal has also been designed and fabricated. As more rings and Oseal junctions are attached, the volume of the resonator grows. By blowing the mouth of the Helmholtz resonator with different sections, different resonance frequencies can be measured. From these measurements, several parameters can be estimated indirectly, such as the speed of sound waves, the room temperature, and air density. 3D printing permits to analyse several scenarios without using uncomfortable strategies to vary the bottle's volume, such as water, reducing the hazard in a laboratory with electronic instrumentation.
