Non Planar Ironing

Non-planar Ironing g-code generation to make FDM 3D prints up to 10x smoother

Overview

Non-Planar Ironing

A novel technique for Smoother Surface Finishes in FDM printing

• Left - Standard printing
• Middle - Best Previous Technique
• Right - Our technique

Run Non-planar Slic3r

This is based off non-planar slic3r which can be found here (or as a sub-repository): https://github.com/Zip-o-mat/Slic3r

Slic3r settings

Slic3r has odd defaults, so make sure to set them properly. Things to look out for include:

• Default layer height
• Default Nozzle diameter
• Default filament diameter

Run the script

Add a file to tge root of this repo named .input.gcode. It should have the following content:

G1 X0 <YFinal> Z0 E0  ; Get opposite y coordinate (to zig-zag)
G1 <X0> <Y0> <Z0> E0  ; Go to start point
G1 <X1> Y0 <Z1> E0    ; Increment along the XZ plane
G1 <X2> Y0 <Z2> E0
G1 <X3> Y0 <Z3> E0
ETC

If a number does not have <> around it it can be value.

The Blue dot below represents point 0, the pink dot point Final.

Then run the code.ipynb notebook.
