Blobbing Blobbing occurs in 3D printing when excess material accumulates on specific areas of a print, creating unwanted lumps or irregularities. This defect is often caused by over-extrusion, excessive nozzle temperature, or poor retraction settings. Blobs can disrupt the surface quality of the print and may interfere with the model's functionality. To minimize blobbing, users can optimize retraction settings, adjust print temperatures, and ensure proper filament feeding. Advanced slicers often include features like coasting or wiping to reduce material buildup at the end of extrusion paths. |
