Distributed digital manufacturing of free and open-source scientific hardware (FOSH) used for scientific experiments has been shown to in general reduce the costs of scientific hardware by 90-99%. In part due to these cost savings, the manufacturing of scientific equipment is beginning to move away from a central paradigm of purchasing proprietary equipment to one in which scientists themselves download open-source designs, fabricate components with digital manufacturing technology, and then assemble the equipment themselves. This trend introduces a need for new formal design procedures that designers can follow when targeting this scientific audience. This study provides five steps in the procedure, encompassing six design principles for the development of free and open-source hardware for scientific applications. A case study is provided for an open-source slide dryer that can be easily fabricated for under $20, which is more than 300 times less than some commercial alternatives. The bespoke design is parametric and easily adjusted for many applications. By designing using open-source principles and the proposed procedures, the outcome will be customizable, under control of the researcher, less expensive than commercial options, more maintainable, and will have many applications that benefit the user since the design documentation is open and freely accessible.

“…There is substantial evidence that releasing innovations and inventions using open source licenses can indeed maximizes societal benefits [5,[60][61][62] as it leads to all of the benefits in FOSS [14][15][16][17][18][19][20][21][22][23] and FOSH [30][31][32][33][34][35][36][41][42][43][44][45][46][47] development discussed above. As the open source development of digital fabrication tools such as 3-D printers, mills and laser cutters [31][32][33][34] are coupled with software that enables convenient customization [63] and free public resources for open source design exchange [64,65], peer production can emerge [66]. These practices bring high value products to consumers for lower costs than what is available on the market for a wide range of consumer products [67][68][69] ranging from toys [70] and educational aids [71][72][73][74]…”

As a growing number of companies reject intellectual property (IP) monopoly-based business models to embrace libre product development of free and open source hardware and software, there is an urgent need to refurbish the instruments of university-corporate research partnerships. These partnerships generally use a proprietary standard research agreement (PSRA), which for historical reasons contains significant IP monopoly language and restrictions for both the company and the university. Such standard research agreements thus create an artificial barrier to innovation as both companies using a libre model and universities they wish to collaborate with must invest significantly to restructure the contracts. To solve this problem, this article provides a new Sponsored Libre Research Agreement (SLRA). The differences between the agreements are detailed. The advantages of using an SLRA are provided for any type of company and include: (1) minimizing research investments on reporting requirements; (2) reducing delays related to confidentiality and publication embargos; and (3) reducing both transaction and legal costs as well as research time losses associated with IP. Moving to libre agreements both speeds up and reduces costs for setting up collaborative research. Under the SLRA, university researchers can spend more time innovating for the same investment.

For example, Android, an open source-based operating system, is the world's most popular operating system [26], 97% of the world's supercomputers use GNU/Linux [27], and major Internet-based corporations use and develop FOSS including: Amazon, Alphabet (Google), Twitter and Facebook. These companies and others use FOSS because of superior technical performance, more flexible design and reduced research and development (R&D) costs [28].

A Secure Data Infrastructure for Personal Manufacturing Based on a Novel Key-Less, Byte-Less Encryption Method

et al. 2020

We are witnessing the advent of personal manufacturing, where home users and small and medium enterprises manufacture products locally, at the point and time of need. The impressively fast adoption of these technologies indicates this approach to manufacturing can become a key enabler of the real-time economy of the future. In this paper, we contribute a secure and dependable infrastructure and architecture for that new paradigm. Our solution leverages physical limitations of the computational process into a defense strategy that makes distributed file storage and transfer highly secure. The main idea is to replace asymmetric or public-key encryption functions with an unkeyed, collision, second preimage, and preimage resistant cryptographic hash function. Such a cryptosystem does not have an inverse function H-1. We challenge each block hash against the full hash table to recreate the original message. To illustrate the approach, we describe secured protocols that provide a number of desirable properties during both data storage and streaming. Similar to proof-of-work blockchain consensus algorithms, we parameterized the solution based on the amount of infrastructure available. Experiments show the proposed method can recalculate hashes for a 3-dimensional live matrix of 256 3 at an average of 14 revisions per second, and one revision every 5 minutes for a bigger matrix of 4096 3. The increase in cloud infrastructure cost is insignificant compared to the level of protection offered.
