Layer shifting, poor bed adhesion, and inconsistent extrusion can derail a project and waste valuable time and materials. Inspect linear rods for dust buildup and ensure smooth rotation of the bearing blocks.
Fixing Stringing, Blobs, and Under-Extrusion in 3D Printing
Clogged nozzles, incorrect temperature settings, or poor filament quality can starve the hotend of material or force it to leak uncontrollably. You should regularly verify that your bed is level relative to the nozzle and that the X and Y axes move smoothly without binding.
Moisture absorption in materials like nylon or PETG expands into gas when heated, causing popping and irregular flow. A loose belt or misaligned rod forces the printer to skip steps, causing visible layer shifting on tall or large prints.
Fixing Stringing and Blobs: Solutions for Under-Extrusion Issues
Filament Type Typical Nozzle Temp (°C) Common Extrusion Issues PLA Stringing, overheating ABS 230–250 Layer separation, warping TPU 220–240 Under-extrusion, jamming Bed Adhesion and Warping Poor bed adhesion sends prints curling up before they finish, turning hours of work into scrap. Verify that the print bed is securely fastened and completely flat.
