The high moisture content of 3D printing filaments such as PLA, Nylon, PETG, ABS, and others, has adverse effects on the polymers’ mechanical and thermomechanical properties. The wet filament is a source of a wide array of issues in printed parts, such as stringing, foaming, reduced mechanical strength, in some cases complete print failures, and other issues. Ensuring low moisture content of hygroscopic 3D printing filaments is vital for producing consistent 3D printed parts.
Several filament drying and storage solutions have been developed and are available for consumers to purchase. However, while the basic components of all these solutions are low-priced, these products are sold at a significant premium and are often inaccessible to budget-constrained and low-income 3D printer users.
This thesis work aimed to develop electronics hardware for a prototype of a low-cost filament drying controller and power converter. The main objective of this work was to produce a first-version prototype for developing control loop software and modifying and optimizing the filament drying process.
The work was conducted in a home laboratory, the components were sourced from local vendors, and the materials were found on the component manufacturer’s websites and via Google Scholar. Online resources from hobbyists were used to source information about filament drying.
As a result, a controller board and a front panel board were developed, manufactured and tested. The power converter board was designed, but not manufactured and tested. Overall, the project showed the possibility of developing a low-cost filament dryer. However, the final results did not achieve the desired cost and goals.
