What should i do if the material tends to wrinkle in the sharp parts?

Material wrinkling on sharp parts during 3D printing is a common problem caused by material shrinkage and built-up stresses.


FACTORS INFLUENCING MATERIAL SHRINKAGE:

  • CHOOSING THE RIGHT MATERIAL: Consider whether it is essential to use the current material for your print. Sometimes, there are versions of materials with less shrinkage. Choosing a material with different characteristics might solve the problem of ripple.
  • SHRINKAGE MANAGEMENT: Ripple is directly related to shrinkage that occurs during material cooling. You can consider using materials with a low shrinkage rate or adjust your print settings to minimize this effect.
  • MODEL ORIENTATION: Changes the orientation of the model in the printout. Examining the arrangement of objects in the print can help reduce wrinkling. Experiment with different angles and orientations to find the best solution.

To address this issue, you can take several steps depending on the goals of your print:

IF YOU ARE PRINTING A PART WITH MECHANICAL PRECISION:

  • LOWER THE LAYER HEIGHT: Reduce the layer height when printing. This can improve accuracy and reduce the rippled effect on sharp parts.
  • INCREASE COOLING FANS: Increase the speed or intensity of the cooling fans on your 3D printer. This helps to cool the material more quickly and reduce tensions.
  • REDUCE THE TEMPERATURE SLIGHTLY: Reduce the temperature of the extruder slightly. This can help reduce material shrinkage.
  • REDUCE SPEED: Decrease the print speed. Printing more slowly can allow the material to settle more evenly and reduce tensions.

IF YOU ARE PRINTING FOR AESTHETIC APPEARANCE:

  • INCREASE FLOW: Increases the flow of material during printing. This can help to better fill in the sharp parts and reduce the frizzy effect.

IF THE PROBLEM PERSISTS:

  • LOWER THE LAYER HEIGHT: If the problem continues, further consider lowering the layer height to achieve greater accuracy.
  • INCREASE IN COOLING FANS: Keep experimenting with cooling fans. Increased cooling can often improve the aesthetic appeal of printed parts.
  • REDUCE THE TEMPERATURE SLIGHTLY: If material shrinkage is still an issue, you can further reduce the temperature of the extruder.
  • REDUCE SPEED: Reduce the print speed to allow for greater accuracy in sharp parts.

By experimenting with these settings and taking appropriate measures, you can improve the quality of your printed parts and reduce wrinkling on sharp parts. The best solution will depend on your specific printing needs and the material used.
