1. 📌 Poor Bed Adhesion

Symptoms:

  • First layer doesn’t stick well

  • Filament detaches during printing

  • Bed not properly leveled

  • Inadequate bed temperature

  • Dirty or worn bed surface

  • Incorrect Z-offset distance

  • Level bed using paper as a reference

  • Adjust bed temperature based on material

  • Clean the surface with isopropyl alcohol

  • Correct Z-offset in slicer or firmware

2. 🧵 Filament Tangles

Symptoms:

  • Filament stops mid-print

  • Clicking sounds from extruder

  • Poorly wound spool

  • Excessive extruder tension

  • Low-quality filament

  • Check proper spool mounting

  • Adjust extruder tension as per specs

  • Use high-quality filament (like GST 3D)

3. 🌡 Incorrect Printing Temperatures

Symptoms:

  • Poor layer bonding

  • Filament over- or under-melting

Adjust temperature according to material:

|Material  | Nozzle (°C) | Bed (°C) | Notes |

| PLA        | 190–210     | 50–60     | Fan at 100% |

| PETG      | 220–240     | 70–80     | Fan at 50% |

| ABS       | 230–250      | 90–110   | Requires enclosure |

| TPU       | 210–230      | 50–60     | Print slow (20–30 mm/s) |

4. 🧨 Warping (Part Deformation)

Symptoms:

  • Lifted corners

  • Curved base

  • Thermal contraction

  • Poor bed adhesion

  • Air drafts

  • Use heated bed appropriately

  • Apply adhesives (hairspray, tape, glue stick)

  • Enclose print area or avoid drafts

  • Add brim or raft in slicer

5. 🔧 Nozzle Clogs

Symptoms:

  • No filament extrusion

  • Clicking from extruder

  • Debris in the nozzle

  • Contaminated filament

  • Wrong temperature

  • Perform a cold pull

  • Replace nozzle if needed

  • Set correct nozzle temperature

6. 🪨 Stringing (Unwanted Threads)

Symptoms:

Fine threads between printed parts

  • Nozzle temperature too high

  • Improper retraction settings

  • Lower nozzle temperature in 5°C steps

  • Adjust retraction distance and speed in slicer

7. 🏛 Layer Shifting

Symptoms:

Misaligned layers

    • Loose belts

    • Dirty or dry axes

    • Too high print speed

  •  

  • Tighten belts

  • Clean and lubricate rails and bearings

  • Reduce print speed

8. 🔹 Under-Extrusion

Symptoms:

  • Gaps or missing material in layers

  • Thin or incomplete parts

  • Partial nozzle clog

  • Inconsistent filament diameter

  • Incorrect flow rate settings

  • Clean or replace nozzle

  • Use quality filament with strict tolerances

  • Increase extrusion flow in slicer gradually

9. 🔥 Part Overheating

Symptoms:

  • Warped or melted upper layers

  • Loss of detail

  • Too high nozzle temperature

  • Low print speed

  • Poor cooling

  • Lower nozzle temperature

  • Increase print speed

  • Improve cooling using fans or slicer settings

10. 🌬 Cooling Issues

Symptoms:

Poor bridge and overhang quality

  • Faulty or misplaced cooling fans

  • Inadequate slicer fan settings

  • Verify fan placement and function

  • Optimize cooling speed in slicer

🔊 General Printing Tips

  • Always use dry filament

  • Clean the nozzle and extruder regularly

  • Use reliable slicers: Cura, PrusaSlicer, OrcaSlicer

  • Save verified profiles from GST 3D

  • Update firmware when needed
