Solution: When prntng wth PLA. PETG, and other low-temp materals, keep the printer chamber door open Note: In hot summer weaher, It'srecommended to use air conditioning while printing

Solution: When printing flexble materals like TPU or TPE, reduce print speed and retraction distance. Its bestto use direct-drive extrusion forsuch materials

Solution:Check for excessive wear on the extruder gear. Replace i worn, and adjust gear tension appropriately

Solution: Measure the flament diameter. If deviation is too large, replace with a filament of consistent diameter

Solution: Extended use or abrasrve materials lke carbon fber can cause buldup and wear inside the nozzle. Regular ceaning is necessary.Use a hardened steel nozzle for carbon fiber. If unclogging fails, replace the nozzle

Solution:Reduce print speed, increase nozzle temperature to improve material flow

Solution: Check that the temperature is correctly set for the material in use. If incorrect increase the nozzle temperature accordingly

Solution: The gap between the nozzle and the build plate is too large, causing the extruded ines of the first layer to not be squshed propery.resuting in poor adhesion. Re-level the bed and reduce the nozzle-to-bed gap, or lower the first layer height in the slicer setings

Solution: Materials like ABs, PA, and PC shrink significanty.As the print gets taller, shrinkage can cause the edges to ift. The larger the print
and the lower the ambient temperature, the more likely it is to warp.1.Close the printer enclosure to maintain a stable internal temperature and minimize shrinkage effects.2. Apply adhesve (glue stick etc.)to the buld plate when printing wth shrink-prone materials lke ABS. PA or PC. This Increases bed adhesionand helps prevent warping caused by shrinkage.

Solution: Each material requires a specic bed temperature. Ifthe bed temperature is too low. prints may not adhere propery.Increase the bedtemperature according to the material around 60°C for PLA. 100°C for ABS, and 0°C for PETG. Using PLA settings for ABS. for example, wilcause adhesion failure. The bed temperature should generally be higher than the material's heat defiection temperature

Solution:Higher printing speeds tend to reduce surface gloss. When surface print speeds vary grealy across the model. glos inconsistenciesappear - especially on slower overhang areas. Testing shows that speeds above -8omm/s noticeably reduce gloss.Disable speed reduction features, and ty to keep surtace print speeds consistent to reduce gloss variations.

Solution: Moist filaments generate steam when heated, disrupting flow and causing stringing.
1. Dry the filament before printing, especially hygroscopic ones like PA and TPU. Use a dry box during printing.
2.Lower the nozzle temperature to reduce vaporization and improve stringing issues.

Solution: Heated material at the nozzle fows easiy, so retraction is needed to pullit back and prevent oozing. Ifretraction is insufcient, thefilament won't retract completely and will ooze out, causing stringing.Increase retraction distance and speed. Disable Z-hop during retraction.

Solution:The higher the temperature, the lower the viscosity, and the greater the fow. Overheating makes the filament more prone to oozingand stringing
Lower the nozzle temperature during printing.
(Note: For foaming materials, heating at the nozzle causes expansion, making retraction ineftective. To minimize stinging. reduce travel moves
instead.)

Solution: If cooling s too rapid during printing, extruded layers wont bond properiy. leading to weak layer adhesion or even cracks. This Is morepronounced with high-shrinkage materials like ABS and PA, which require an enclosed and heated environment.1. Reduce cooling speed. Slower cooling improves interlayer bonding and strength.2. Increase print temperature. Higher temperatures improve melt flow and layer bonding.

Solution:When layer helght is too nhigh, the extruded lines dont flatten properly, resuting in poor bonding between layers.Lower the layerheight. Recommended height is 1/4 to 3/4 of the nozzle diameter, with 1/2 being ideal for balancing strength and print time.

Solution: Inadequate extrusion causes weak layer bonding.
1. Increase extrusion multiplier or flow rate.
2. Raise nozzle temperature to improve material flow and extrusion volume3. Replace the nozzle if it is worn and restricting flow.

Solution: Lightweight and silk-like materials have lower structural strength due to their visual and physical properties.Avoid using low-strength materials for functional or load-bearing prints

Solution: If print speed is too fast the extruder can'tkeep up with the nozzle movement, resulting in under-extrusion or gaps. Lower the printspeed to allow consistent extrusion.

Solution: Lowtemperature reduces material tow.leading to under-extrusion and gaps. Use the corecttemperature for each material - forexample. printing PETG or ABS at PLAtemperaure wll cause under-extrustion. Increase the nozzle temperature to improve materal ow. Forhigh-speed printing, raise the temperature by 10-20°C over normal settings.

Solution: A worn nozzle may have a smaller diameter, reducing extrusion volume.Clean or replace the nozle regulary, especialy when switching between materials. For abrasive flaments like carbon fiber, use nardened steenozzles to avoid rapid wear.

Solution: Small pointed features don't cool quickly enough and are prone to deformation.
1. Increase cooling. Set auxiliary fans to maximum or use external fans if needed.
2. Slow down the print speed, ideally below 30mm/s, to allow sufficient cooling time.

Solution: If the nozzle is too far from the bed, the first layer lines won't be squished and won't adhere properiy.Re-level the bed. reduce thenozzle-to-bed gap, or decrease the first layer height.
