“…The ROI is so high that it could be justified even in a single school that uses any substantial number of copies of a learning aid. Particularly if these are for more advanced science classes, like optomechanical systems [96], micropumping [97], bioadhesion [98] or bioreactors [99]. The savings that, on average, are 86% for learning aids would go a long way at a school that makes use of learning aids, but perhaps more importantly, with the costs being accessible, more teachers would be likely to use them and the teaching at a school would be improved.…”

While schools struggle financially, capital for purchasing physical learning aids is often cut. To determine if costs could be reduced for learning aids, this study analyzed classroom-based distributed digital manufacturing using 3-D printing of open-source learning aid designs. Learning aid designs are analyzed in detail for their economic viability considering printing and assembly costs with purchased components and compared to equivalent or inferior commercial products available on Amazon. The results show current open-source 3-D printers are capable of manufacturing useful learning aids and that doing so provides high economic savings in the classroom. Overall, the average learning aid would save teachers 86% when fabricating it themselves. The results show that the average design evaluated was downloaded over 1,500 times and the average savings per year per open-source learning aid design was USD 11,822. To date, the 38 learning aid designs evaluated in this study saved over USD 45,000 each and the total of all of them saved the international educational community over USD 1.7 million. It is clear that investing in the development of open-source learning aids for students provides a return on investment (ROI) for investors hoping to improve education, on average, of more than 100%.

“…A specially designed setup, including a humidity chamber and tissue holder, was developed and fabricated for these experiments (Fig. 1) (Vaut et al, 2019). A heating lamp was placed inside the sealed chamber and was programmed to maintain a temperature of 37 ± 1.1°C.…”

“…3D printing has for example been used to make a sample mixer [12] , a micropipette [13] and a microsyringe autosampler [14] . 3D printing and laser cutting have also been used to fabricate in vitro models, for example a fully replicable retention model to study the intestinal adhesion of microdevices for oral drug delivery [15] . Additionally, 3D printing has been applied to develop a workstation for automated in vitro workflows [16] .…”
