Abstract

As open-source technology and additive manufacturing evolve, their advantages become increasingly evident, offering solutions to global challenges. This thesis presents the development of two open-source 3D-printable hardware tools to accelerate this trend: a melt flow index (MFI) tool and tourniquet tester. The MFI tool is introduced as a low-cost method for measuring the MFI of thermal-sensitive material, particularly assessing their suitability for recycling thermoplastics for 3D printing. The tourniquet tester provides a low-cost instrument for measuring the pressure of tourniquets to assess efficacy. This device offers a cost-effective solution to ensure the safety and functionality of these critical emergency tools including those 3-D printed from recycled materials. By making these designs open-source and reducing production costs, this initiative aims to lower the barriers to use recycled plastics in 3-D printing of high-value medical and scientific devices. Together, these devices support the creation of effective emergency medical tools in resource-limited settings.

Summary for Lay Audience

As open-source technology and additive manufacturing develop, their benefits are increasingly realized, broadening the impact of such innovations. This paper presents the development of two open-source hardware tools: a melt flow indexer and a tourniquet tester both of which are 3D-printable. The purpose of these tools is to provide affordable and accessible solutions for two distinct but important applications.

The melt flow indexer allows users to measure how certain materials flow when melted. This is particularly important for verifying whether a material is suitable for 3D printing. By providing a low-cost method to test these materials, the tool helps reduce the overall expenses associated with plastic recycling. This encourages more people to recycle plastics and use them for 3D printing.

The tourniquet tester is designed to fill a crucial need by offering a low-cost way for individuals to test the effectiveness of tourniquets, which are vital in emergency situations to stop bleeding. This is especially useful for those who use or produce tourniquets made at home or through 3D printing, ensuring these homemade medical devices work correctly when they are needed the most.

By making the designs of these tools open-source, the paper aims to make it easier for people around the world to build and use these testers. This approach not only lowers costs but also promotes more widespread adoption and customization according to individual needs.

These two tools together have the potential to make a significant impact, particularly in areas where access to medical supplies and recycling infrastructure is limited. They enable communities to create their own emergency supplies and recycle materials locally, aligning with broader efforts to enhance sustainability and healthcare accessibility.
