Preventing Warping

Guide

Warping can ruin prints, especially with larger models. Here are some tips to prevent it:

  1. Use a Heated Bed: A heated bed can help keep the print adhered. Set the bed temperature according to the filament manufacturer's recommendations.
  2. Apply Adhesive: Use adhesives like glue stick or hairspray. Apply a thin, even layer to the print bed to improve adhesion.
  3. Print with a Brim or Raft: These can increase bed adhesion. A brim adds a single layer around the base of the print, while a raft adds a thicker base layer.
  4. Control Ambient Temperature: Avoid drafts and maintain a consistent room temperature. Use an enclosure to keep the print area warm and reduce temperature fluctuations.
  5. Use Proper Filament: Some filaments are less prone to warping. PLA is generally less prone to warping than ABS or PETG.

Additional Tips

  • Calibrate Bed Leveling: Ensure the bed is level to provide a consistent surface for the print. Use a piece of paper or a feeler gauge to check the distance between the nozzle and the bed at multiple points.
  • Print Slower: Slower print speeds can improve adhesion and reduce warping. Start with a speed of 40-60mm/s and adjust as needed.
  • Use a Cooling Fan: Use a cooling fan to solidify the filament quickly. This can help prevent warping, especially for smaller prints.

Example Procedure

  1. Level the Bed: Use the bed leveling procedure for your printer to ensure the bed is level.
  2. Set the Bed Temperature: Set the bed temperature according to the filament manufacturer's recommendations. For example, 60°C for PLA, 100°C for ABS.
  3. Apply Adhesive: Apply a thin layer of adhesive to the print bed.
  4. Print with a Brim or Raft: Enable the brim or raft option in your slicing software.
  5. Control Ambient Temperature: Use an enclosure or maintain a consistent room temperature to reduce drafts.

By following these steps, you can prevent warping and improve the overall quality of your prints.
