“…Rather than including parts produced via fused filament fabrication, the updated 3-D printer design was constructed entirely from metal parts to reduce damage caused by weld splatter. Franklin Firmware and the improved metal 3-D printer were used to establish low-cost substrate release mechanisms that allow metal 3-D printed objects to be removed from a metal print substrate with minimal force [23].…”

“…In addition, Franklin has been used in conjunction with a metal inert gas (MIG) weld-based 3-D printer to develop substrate release mechanisms for 3-D printed parts [23]. Traditionally, metal 3-D printed parts must be removed from a print substrate with the use of saws or other machining equipment.…”

RepRap 3-D printers and their derivatives using conventional firmware are limited by: 1) requiring technical knowledge, 2) poor resilience with unreliable hardware, and 3) poor integration in complicated systems. In this paper, a new control system called Franklin, for CNC machines in general and 3-D printers specifically, is presented that enables web-based three dimensional control of additive, subtractive and analytical tools from any Internet connected device. Franklin can be set up and controlled entirely from a web interface; it uses a custom protocol which allows it to continue printing when the connection is temporarily lost, and allows communication with scripts.

“…Fortunately, an open-source 3-D printer capable of printing in steel and aluminum has been developed, which is essentially an upside-down MOST delta RepRap where the extruder is replaced with a gas metal arc welder [73]. Although there has been significant progress in turning the device into a tool for distributed manufacturing [74], it is still at an early stage of development and not ready for mass deployment. Finally, another example of a tool that could be functional in plastic, but better suited to metal is the heavy-duty rope pulley ( Figure 5).…”

Abstract:There is growing evidence that low-cost open-source 3-D printers can reduce costs by enabling distributed manufacturing of substitutes for both specialty equipment and conventional mass-manufactured products. The rate of 3-D printable designs under open licenses is growing exponentially and there are already hundreds of designs applicable to small-scale organic farming. It has also been hypothesized that this technology could assist sustainable development in rural communities that rely on small-scale organic agriculture. To gauge the present utility of open-source 3-D printers in this organic farm context both in the developed and developing world, this paper reviews the current open-source designs available and evaluates the ability of low-cost 3-D printers to be effective at reducing the economic costs of farming. This study limits the evaluation of open-source 3-D printers to only the most-developed fused filament fabrication of the bioplastic polylactic acid (PLA). PLA is a strong biodegradable and recyclable thermoplastic appropriate for a range of representative products, which are grouped into five categories of prints: hand tools, food processing, animal management, water management and hydroponics. The advantages and shortcomings of applying 3-D printing to each technology are evaluated. The results show a generalizable technical viability and economic benefit to adopting open-source 3-D printing for any of the technologies, although the individual economic impact is highly dependent on needs and frequency of use on a specific farm. Capital costs of a 3-D printer may be saved from on-farm printing of a single advanced analytical instrument in a day or replacing hundreds of inexpensive products over a year. In order for the full potential of open-source 3-D printing to be realized to assist organic farm economic resiliency and self-sufficiency, future work is outlined in five core areas: designs of 3-D printable objects, 3-D printing materials, 3-D printers, software and 3-D printable repositories.

“…This technology presents the capability of producing objects of different geometries or shapes, using different materials, such as polymers [5], free-standing liquid metals [6,7], solid metals [8,9], ceramics, clays, epoxy resin [10], and even living cells [11] and organs [12]. The introduction into the market of the RepRap (a self-Replicating Rapid prototyper) as the first free and open source 3-D printer released under the GNU General Public License led to the rapid technical evolution of RepRap 3-D printers [13][14][15][16].…”

Abstract:The release of the open source 3-D printer known as the RepRap (a self-Replicating Rapid prototyper) resulted in the potential for distributed manufacturing of products for significantly lower costs than conventional manufacturing. This development, coupled with open source-appropriate technology (OSAT), has enabled the opportunity for 3-D printers to be used for sustainable development. In this context, OSAT provides the opportunity to modify and improve the physical designs of their printers and desired digitally-shared objects. However, these 3-D printers require electricity while more than a billion people still lack electricity. To enable the utilization of RepRaps in off-grid communities, solar photovoltaic (PV)-powered mobile systems have been developed, but recent improvements in novel delta-style 3-D printer designs allows for reduced costs and improved performance. This study builds on these innovations to develop and experimentally validate a mobile solar-PV-powered delta 3-D printer system. It is designed to run the RepRap 3-D printer regardless of solar flux. The electrical system design is tested outdoors for operating conditions: (1) PV charging battery and running 3-D printer; (2) printing under low insolation; (3) battery powering the 3-D printer alone; (4) PV charging the battery only; and (5) battery fully charged with PV-powered 3-D printing. The results show the system performed as required under all conditions providing feasibility for adoption in off-grid rural communities. 3-D printers powered by affordable mobile PV solar systems have a great potential to reduce poverty through employment creation, as well as ensuring a constant supply of scarce products for isolated communities.
