Notes on Creality K1C Review

Introduction

• Creality K1C marketed for carbon fiber-filled filaments.
• Author views it as Creality's "do-over" for previous issues with K1.
• Not sponsored; products were sent for review.

Background

• K1 launched to much fanfare, aimed to compete with Bambu Lab.
• Introduced CoreXY kinematics, improved performance, and user-friendliness.
• Early models had significant issues, particularly with usability.
  • Reviewers received models plagued with problems.

Key Improvements in K1C

• Extruder Issues:

  • K1 had major extruder problems, leading to underextrusion.
  • K1C features a new robust all-metal extruder with a hardened-steel quick-swappable nozzle.
  • Testing shows no underextrusion issues with various materials (PLA, PETG, etc.).

• Bed Leveling and Adhesion:

  • K1 had problems with bed meshing and leveling.
  • K1C includes a silicone brush to aid in bed leveling.
  • Critique of the single-sided smooth PEI bed; lacks double-sided option.
  • Despite constraints, the smooth PEI works well for various materials.

• Firmware and Slicing Experience:

  • K1's software and firmware were initially poor; limited features.
  • K1C allows root access, supporting open-source firmware (Klipper).
  • Users can install various custom software without sacrificing interface.
  • Improved web interface and smartphone app; still room for improvement.

• Camera and AI Failure Detection:

  • K1C includes a camera for remote monitoring; AI detection in beta.
  • Some compatibility issues with third-party apps.

• Hot End Issues:

  • Previous K1 had thermistor problems; random print failures.
  • K1C shows no such issues; can print high temp materials effectively.

• Vertical Fine Artifacts (VFAs):

  • K1 used small pulleys leading to VFAs.
  • K1C updated with larger pulleys; reports indicate issues resolved.

• Design Improvements:

  • Door design improved; now more secure and stable.
  • Anti-shatter film added to the glass for safety.
  • Addressed warp beds; users report better flatness.

• Spool Placement:

  • K1C includes pre-sliced GCode for a side-mounted spool holder.

• Nozzle Swapping:

  • New "Unicorn" nozzle system allows tool-free swapping.
  • Concerns about proprietary nozzles; a need for compatibility with existing standards.

Final Verdict

• The K1C represents significant improvements over the original K1.
• Author recommends it as a solid option for high-quality prints at a competitive price.
• Still a Creality K1 at its core, but with enhanced features and performance.
• Overall impression: Phenomenal, might even recommend over Bambu Lab P1S under certain conditions.
