// FlipLines Infill: Enhances 3D Printing Speed & Reduces Noise
|
||||
// FlipLines, as its name hints, alternates line direction by 90 degrees every few layers to improve adhesion.
|
||||
// It introduces transform layers between direction shifts for better line cohesion, which fixes the weakness of line infill.
|
||||
// The transform technique is inspired by David Eccles, improved 3D honeycomb but also a more flexible implementation.
|
||||
// This method notably increases printing speed, meeting the demands of modern high-speed 3D printers, and reduces noise for most layers.
