Efforts to encourage laboratory automation through student access to and usage of commercial equipment are hampered by prohibitive acquisition costs. Here, an automated liquid handler using manual pipettes was developed to operate on a commercial hobbyist 3D printer at a cost of US $325. Arising from an iterative design process that ensured…

3D-printing (3DP) is a rapidly evolving sector and is advancing at an unmatched pace. Integrating digital-based approaches to disseminate knowledge within institutional curricula is crucial for mainstreaming knowledge. This work explores the development of a virtual lab (VL) for additive manufacturing (AM), using an interactive VL simulator. The…

We present the design of a periscope-type VIS spectrometer for educational purposes that combines strong features from various earlier designs and adds new ones. Three 3D-printed pieces that hold a small thin mirror sheet, a 1/8th wedge of a DVD, and two razor blades are easily assembled and facilitate insight into its construction. A new feature…

Capital and property have been combined since Karl Marx wrote "Das Kapital" in 1867. Indeed, capitalism and the housing market are interlinked because property is an asset whose indexed value upholds global markets. On the other side of property as real estate is the environmental damage and augmentation of climate change that housing…

The use of radioactive isotopes in radioactive decay studies can be a problem due to the manipulation of radioisotopes, expensive equipment, and the difficulty of finding samples with a reasonable half-life (between 1 and 10 min). In this paper, we present a mock-up of a Geiger-Mu¨ller counter plus three fictitious radioisotopes. They form an…

In this paper we present a collaborative 3D modeling and printing experience within a Project Based Learning (PBL) activity, carried out with two different groups of participants: pre-service teachers at the Universidad Autónoma de Madrid (Spain), and school students of Primary and Secondary level taking part in an extra-curricular activity.…

In recent decades, the application and adaptation of new technologies have gradually become invaluable in education. When the students are visually impaired, the use of these technologies becomes even more valuable. In this line, a theoretical-practical workshop on human evolution was carried out with 25 students from the Spanish National…

Health concerns from 3D printing were first documented by Stephens, Azimi, Orch, and Ramos (2013), who found that commercially available 3D printers were producing hazardous levels of ultrafine particles (UFPs) and volatile organic compounds (VOCs) when plastic materials were melted through the extruder. UFPs are particles less than 100 nanometers…

As 3D printers become more affordable, schools are using them in increasing numbers. They fit well with the emphasis on product design in technology and engineering education, allowing students to create high-fidelity physical models to see and test different iterations in their product designs. They may also help students to "think in three…

Opportunities to utilize 3D printing in the K-12 classroom are growing every day. This paper describes the process of implementing a 3D printing service in the Education Library of The University of Florida, Gainesville, a large, doctoral-degree granting, research university. Included are examples of lesson plans featuring 3D printing, creation of…

The appearance of 3D printers in university libraries opens many opportunities for advancing outreach, teaching, and research programs. The University of Alabama (UA) Libraries recently adopted 3D printing technology and maintains an open access 3D Printing Studio. The Studio consists of a 3D printer, multiple 3D design workstations, and other…
