Although the environmental benefits of recycling plastics are well established and most geographic locations within the U.S. offer some plastic recycling, recycling rates are often low. Low recycling rates are often observed in... more
The concept of Open Design has been embraced by numerous initiatives in design, from furniture to textiles, from product design to social design since its introduction in the ear- ly 2000s.1 Open Design has also brought a revival to... more
Floating photovoltaic (FPV) technology is gaining prominence as a means to alleviate land use conflicts while obtaining large solar PV deployments and simultaneously reducing evaporated water loss. In this study, an open source... more
Logistics management is an important aspect in real-time applications. Some of the aspects like a delay in delivery, identification of freight vehicles in real time, cargo overload, misplacement is some of the issues facing logistics... more
A partnership has formed between eighteen organizations to produce the Open Solar Outdoors Test Field (OSOTF), which has been designed to provide critical data and research on solar photovoltaic (PV) systems optimization in the public... more
Historically, open source agriculture (OSA) was based on grassroots technology generally manufactured by hand tools or with manual machining. The rise of distributed digital manufacturing provides an opportunity for much more rapid... more
The combination of open-source software and hardware provide technically feasible methods to create low-cost, highly-customized scientific research equipment. Open-source 3-D printers have proven useful for fabricating scientific tools.... more
Nitrate, the most oxidized form of nitrogen, is regulated to protect people and animals from harmful levels as there is a large over abundance due to anthropogenic factors. Widespread field testing for nitrate could begin to address the... more
The recent development of open-source 3-D printers makes scaling of distributed additive-based manufacturing of high-value objects technically feasible. These self-replicating rapid prototypers (RepRaps) can manufacture approximately half... more
This study explores the potential to reach a circular economy for post-consumer Recycled Polyethylene Terephthalate (rPET) packaging and bottles by using it as a Distributed Recycling for Additive Manufacturing (DRAM) feedstock.... more
"Open-Source Lab: How to Build Your Own Hardware and Reduce Scientific Research Costs details the development of the free and open-source hardware revolution. The combination of open-source 3D printing and open-source microcontrollers... more
Although theoretically the patent system is meant to bolster innovation, the current United States Patent and Trademark Office (USPTO) is cumbersome and involves a significant time investment to locate inactive patents less than 20 years... more
The importance of quality of the measured values is very dependent on the device that measures these values: the size of the sample, the time of measurement, periods of measurement, the mobility and the robustness of the device, etc.... more
The recent development of the RepRap, an open-source self-replicating rapid prototyper, has made 3-D polymer-based printers readily available to the public at low costs (<$500). The resultant uptake of 3-D printing technology enables for... more
In more than five years of activity, the Free Art and Technology Lab (F.A.T. Lab) produced an impressive series of projects, all developed with open source software, shared online and documented in a way that allows everybody to copy,... more
The open source introduction of fused filament fabrication (FFF) enables distributed manufacturing of consumer products. However, with a wide range of low-cost FFF 3-D printers and settings possible, there is a lack of information on the... more
Syringe pumps are widely used in a multitude of tasks where precise volumes of an extru-date need to be delivered at a specific flow rate. In the past decade various open source syringe pump designs have accelerated scientific research... more
To overcome the challenge of upcycling plastic waste into 3D printing filament in the distributed recycling and additive manufacturing systems, this study designs, builds, tests and validates an open source filament diameter sensor for... more
