PRINT QUALITY TROUBLESHOOTING GUIDE
Not Extruding At Start:
Printer does not extrude plastic at the beginning of the print.
1. Extruder was not primed before beginning the print.
2. Nozzle starts too close to the bed.
3. The filament has stripped against the filament gear.
4. The extruder is clogged.
Print Not Sticking To The Bed:
The first layer does not stick to the bad and the print quickly fails.
1. Hot Bed is not level.
2. Nozzle starts too far away from the bed.
3. First layer is printing too fast.
4. Temperature or cooling settings.
5. The Hot Bed surface (tapes, glues, sprays, material)
6. When all options fail: Use brims and rafts.
Under-Extrusion:
Printer does not extrude enough plastic, gaps form between perimeters and
infill.
1. Incorrect filament diameter.
2. Increase flow multiplier.
Over-Extrusion:
Printer extrudes too much plastic, prints look very messy.
1. Decrease flow multiplier.

- Page 2 Pro 3D PC 3D Printer Gaps in Top Layer: Holes or gaps appear in the top layer of the print. 1. Not enough top solid layers 2. Infill percentage is too low. 3. Under-Extrusion. Stringing or Oozing Lots of strings and hairs left behind when moving between different sections of the print.
- Page 3 Pro 3D PC 3D Printer Layer Separation and Splitting Layers are separating and splitting apart while printing. 1. Layer height is too large. 2. Print temperature is too low. Grinding Filament Plastic is being ground away until the filament no longer moves, otherwise known as 'stripped' filament.
- Page 4 Pro 3D PC 3D Printer Weak infill Very thin, stringy infill that creates a weak interior and does not bond together well. 1. Try alternate infill patterns. 2. Lower the print speed. 3. Increase the infill extrusion width.???? Blobs and Zits Small blobs appear on the surface of prints also know as zits.
- Page 5 Pro 3D PC 3D Printer Gaps in Floor Corners Gaps in the corners of the print, where the top layer does not join to the perimeter of the next layer. 1. Not enough perimeters 2. Not enough top solid layers.
- Page 6 Pro 3D PC 3D Printer Inconsistent Extrusion Extrusion amount tends to vary and is not consistent enough to produce an accurate shape. 1. Filament is stuck or tangled. 2. Clogged extruder. 3. Too low layer height. 4. Incorrect extrusion width.
- Page 7 Pro 3D PC 3D Printer Dimensional Accuracy Dimensional issues where the measured dimensions do not match the original design intent. 1. Impact of first layer dimensional accuracy. 2. Under or Over Extrusion. 3. Adjust original part size. Poor Bridging Sagging, drooping, or gaps between the extruded segments of your bridging regions.
