Print Defects & Solutions

Common Print Defects

Poor First Layer

Gaps, ripples, or weak adhesion in the first layer

Bridging

Filament sagging or drooping across gaps

Warping

Corners or edges lifting off the build plate

Under-Extrusion

Thin walls, gaps between lines, weak prints

Poor Layer Adhesion

Parts delaminate or split between layers

Z-Wobble / Z-Banding

Repeating horizontal lines or patterns on sides

Filament & Feeding Issues

Unclogging Nozzles

Clogged nozzle – no or intermittent extrusion

Cold Pull

Clear clogs and clean the nozzle from the inside

Hotend Filament Jamming

Heat creep jams – print stops or under-extrudes

Filament Breaks Inside Tube

Rigid filament snapping inside the PTFE tubes

Filament Tube Compressing

Accordion effect in the PTFE tube disrupts feeding

Settings & Optimization

Print Speeds

Under-extrusion, layer shifting, ringing, or ghosting

Volumetric Flow Rate

Quality degrades at higher speeds

Layer Times & Cooling

Melted features, poor adhesion, saggy overhangs

Layer Height & Line Width

Visible layer lines, gaps, weak adhesion

Pressure Advance

Rounded corners, bulging seams

Mechanical & Material Issues

Part Placement

Failures in certain build plate areas

Infill vs Walls

Unexpected strength or print time issues

Nozzle Material & Size

Frequent clogging or wear

Material Guides

Material-specific chamber and bed temperature guidance

Motion System Adjustment

Binding or misalignment causing wall artifacts

Material Tuning

Calibrate temperature and flow for a new material

Temperature & Electrical

Heater Faults

Temperature errors that interrupt prints

PID Tuning

Temperature oscillation causing surface ripples
