Common failures in amateur 3D printing: Becoming familiar with and improving fused filament fabrication processes

Abstract

3D printing polymers using the method of fused filament fabrication (FFF) is currently the most cost-effective method for the public to utilize additive manufacturing. To print working parts effectively there are many factors that amateur printers, students, and/or hobbyists do not consider. These factors are outlined here in three categories of common novice printing failures which include design flaws in the part, material/manufacture for the chosen application, and factors that can be fine-tuned and controlled during the manufacturing process. Many of the failures can be remedied or mitigated with printer tuning and overall experience manufacturing with the FFF method to become familiar with the process.
