Oral Rehydration Solutions (ORS) Case Study

High School Students Solving Third- World Problems with 3D Printing 

In October of 2016, two seniors - Jack Waters and
Jacob Dubner - submitted a proposal to develop a simple tool that could help combat diarrheal diseases, such as cholera, in developing nations.
Their research highlighted major issues in current best practices associated with fighting the symptoms of these diseases, specifically with the use of Oral Rehydration Solutions (ORS) .

Manufacturing OR Tubes In the summer of 2017, after graduating from Winchester Thurston, Jack and Jacob began their relationship with Omni Med, a nonprofit that trains Village Health Teams (VHT’s) to administer ORS in Uganda . Omni Med ordered a small batch of ORTubes with instructions; and the ORTubes were field tested by Village Health Teams in Ugandan villages.

In order to successfully deliver on the ORTubes for Omni Med, the students turned to the MakerGear M2 printer for production. Throughout their iterative design process Jack and Jacob really dove into the process behind 3D printing and the difference between the variety of printers we have at Winchester Thurston. The MakerGear prints reliably and quickly . The students often setup 6 ORTubes on the printer and let it run for 18+ hours, always returning to successful prints. The team experimented with a variety of plastics and nozzle diameters, settling on a 0.50 mm nozzle and using an FDA-approved, dishwasher safe, high-temp PLA. The ability to quickly change out V4 extruders on the M2 and fine-tune the temperature settings of both the extruder and the heated bed ensured reliable and repeatable prints every time.

Armed with feedback from the field testing, Jack and Jacob began to re-work their design and continued to develop their relationship with Omni Med while successfully navigating their freshman year of college.  In June of 2018, Jack and Jacob again used the MakerGear M2 to deliver a fresh batch of ORTubes to Uganda. This time they traveled to Uganda with Omni Med to personally train the VHT’s and experience life in Uganda as they collected data on the use of their device.

Jack and Jacob are currently looking for funding to mass- produce their ORTube, hoping to get them into the hands of thousands of VHT’s working across Uganda and beyond.
