“…While commercial hardware producers play an important role in the 3D printer market, the rapid rise in consumer-level 3D printers is in part attributable to the emergence of various open source 3D printer initiatives (Tech et al, 2016). The open source character of these printers generally provides for free access to the underlying blueprints, combined with the permission for third parties to freely use and adapt the designs.…”

This article outlines findings from a study in South Africa and Kenya that explored social entrepreneurs’ use of fabrication laboratories (fab labs), and in particular fab lab 3D printing services, in order to advance their social innovations and enterprises. Based on interviews with representatives of fab lab initiatives and social enterprises, the study found strong linkages between social entrepreneurship and fab labs, and between social entrepreneurs and the use of 3D printing technology. However, it was also found that social entrepreneurs tend not to rely primarily on fab labs for access to 3D printers, preferring to buy and build their own printer units—a practice made cost-effective through the selection of low-cost, open source models. In respect of the computer-aided design (CAD) software used to design the files for 3D printing, it was found that social entrepreneurs prefer the stability and user-friendliness of proprietary CAD software, despite the cost implications. At the same time, it was found that social entrepreneurs frequently use free and open source CAD files available online, and that they seek, in turn, to share their designs on a free and open source basis.

“…The straightforward fabrication of complex structures with a resolution under millimeter scale using entry-level and open-source hardware 3D printing could be an alternative for the engineering of small-dimension structures [29]. Several microfluidics application requires hundreds micrometer features [14,30,31], which can be achieved using low cost 3D printing, such as connector, mixer or serpentine channels.…”

Versatile and Low-Cost Fabrication of Modular Lock-and-Key Microfluidics for Integrated Connector Mixer Using a Stereolithography 3D Printing

et al. 2022

We present a low-cost and simple method to fabricate a novel lock-and-key mixer microfluidics using an economic stereolithography (SLA) three-dimensional (3D) printer, which costs less than USD 400 for the investment. The proposed study is promising for a high throughput fabrication module, typically limited by conventional microfluidics fabrications, such as photolithography and polymer-casting methods. We demonstrate the novel modular lock-and-key mixer for the connector and its chamber modules with optimized parameters, such as exposure condition and printing orientation. In addition, the optimization of post-processing was performed to investigate the reliability of the fabricated hollow structures, which are fundamental to creating a fluidic channel or chamber. We found out that by using an inexpensive 3D printer, the fabricated resolution can be pushed down to 850 µm and 550 µm size for squared- and circled-shapes, respectively, by the gradual hollow structure, applying vertical printing orientation. These strategies opened up the possibility of developing straightforward microfluidics platforms that could replace conventional microfluidics mold fabrication methods, such as photolithography and milling, which are costly and time consuming. Considerably cheap commercial resin and its tiny volume employed for a single printing procedure significantly cut down the estimated fabrication cost to less than 50 cents USD/module. The simulation study unravels the prominent properties of the fabricated devices for biological fluid mixers, such as PBS, urine and plasma blood. This study is eminently prospective toward microfluidics application in clinical biosensing, where disposable, low-cost, high-throughput, and reproducible chips are highly required.
