Contamination Contamination in 3D printing refers to the presence of unwanted particles, debris, or materials that can disrupt the printing process. Common sources include dust, filament residue, or mixing incompatible materials in the same nozzle. Contamination can lead to issues like clogging, under-extrusion, or weakened prints. To prevent contamination, users should store filament in sealed containers, regularly clean the nozzle and extruder, and purge the hot end when switching between different filament types. Maintaining a clean printer environment ensures consistent performance and high-quality prints. |
