Creality Print 7.1.0

Changelog

🚀 New Features

Fuzzy Skin Painting

• Added freeform painting of fuzzy skin regions for localized texture control
• Supports three generation modes: Displacement, Extrusion, and Combined
• Multiple noise types available: Perlin, Billow, and more
• Evolves Fuzzy Skin from a simple roughness effect into a controllable surface design system

Support Interface Ironing

• Extended ironing feature to support contact surfaces
• Performs high-speed, low-flow pass (default 10%) after support printing
• Fills surface gaps and flattens irregularities for a smoother temporary printing base
• Improves bottom surface quality, overhang stability, and fine detail sharpness

Brim Ears

• Supports freeform drawing of localized adhesion structures ("ear-shaped brim") at model edges
• Improves adhesion only where needed, reducing filament waste and post-processing

Embedding Wall into Infill

• Generates periodic interlocking "tooth-like" structures between walls and infill
• Staggered across layers to improve interlayer bonding and structural strength
• Ideal for models where infill is exposed or heavily contacts outer walls

🔧 Optimizations

Color Change Sequence

• Optimized color change sequencing for first few layers in multi-color printing
• Adjacent colors prioritized for continuous printing, reducing purge complexity
• Purge volume reduced by ~10% with no negative impact on final print quality

Layer Artifact Optimization – Under-extrusion After Overhangs

• Addressed common issue of visible under-extrusion lines appearing after overhang sections
• Caused by rapid transitions from overhang slowdown to normal speed, where melt pressure and extrusion flow cannot respond instantly
• Optimized algorithm across seven key parameters:
• Pressure Advance (PA)
• Flow smoothing
• Deceleration speed
• Overhang speed
• Melt chamber temperature
• Under-extrusion timing
• Acceleration
• Validated on multiple printers (K2 Plus, K2 Pro, K1, i7) under identical slicing conditions
• New experimental option available at: Process Settings → Speed → Advanced → "Improve Under-extrusion After Overhangs (Experimental)"
• Default parameters are recommended
