Using a dry erase marker, coat parts of your filament to create unique, colored 3D prints. Start from the extruder mouth and apply marker fluid sparingly for varied color gradients. Purple appears to work best, creating effects like strawberry or faded pink hues. Be cautious with this method, as potential residue or damage to your machine is unclear; more testing is required. Show off your creative results in national colors or holiday themes, but take heed that we're not responsible for any damages caused by this technique. Enjoy experimenting! Remember, webcam quality images may not showcase the full detail of your prints.
