We know that the first layer is the most critical part of any 3D print. If it fails, everything else fails. That's why I developed and refined this .3MF file with the exact settings to guarantee perfect adhesion and a smooth, glass-like finish (or textured, depending on your build plate).

What does this file solve?

Adhesion: Parameters adjusted to prevent warping at the corners.

Over/Underextrusion: Optimized line width to ensure lines merge perfectly without creating relief.

Speed: "Slow Start" setting to ensure maximum precision where it matters most.

Technical Profile Details

This .3MF already contains the necessary slicer modifications.

Tested Material: [Ex: PLA and PETG]

Nozzle: [Ex: 0.4mm]

Initial Layer Height: [Ex: 0.20mm or 0.24mm]

Initial Line Width: [Ex: 0.6mm]

Printers used: Creality Hi and Creality Ender 3 V3 KE

How to Use (Step by Step)

Cleaning: First of all, clean your bed with soap and water. Finger grease is the enemy of the first layer.

Load the File: Open this .3MF file in your Creality Print slicer.

Check the Material: Make sure the nozzle and bed temperatures match the filament you are using.

Print and Observe:

If the lines are separated: Your Z-offset is too high (lower the nozzle).

If the surface is rough/wrinkled: Your Z-offset is too low or there is excessive flow (raise the nozzle).

Good parameters for first layer

0.2mm layer, 2 walls, 100% infill
