This upgraded assembly uses a\n  \u003cstrong\u003e360° surround ceramic heater\u003c\/strong\u003e that wraps the entire block\n  circumference. Full-perimeter contact eliminates the hot and cold zones that\n  develop in single-side cartridge setups, delivering \u003cstrong\u003emore uniform\n  temperature distribution\u003c\/strong\u003e across the entire melt zone.

The K2 Plus upgraded hotend uses a\n  \u003cstrong\u003etitanium alloy heatbreak\u003c\/strong\u003e — titanium's combination of low\n  thermal conductivity and high mechanical strength makes it the optimal material\n  for this role, maintaining a sharper thermal gradient than stainless steel while\n  resisting the wear from abrasive composite filaments.
