GcodeEstimator is a PHP library to estimate the length/weight/cost of filament used for a 3D print through the corresponding gcode file.

Requires PHP >= 7.2.


Unlike other implementations, this library supports most of g-code operations commonly used by 3d printers:

  • all kind of moves (rapid, linear, clockwise arc, counter-clockwise arc)
  • absolute and relative positionings
  • switch between absolute/relative modes
  • current position reset
  • millimeter and inche units

Estimations should be quite realist whatever the slicer/printer you use.


Use Composer to install GcodeEstimator in your project:

composer require "pyrech/gcode-estimator"


Basic usage to get the length of filament used:

include __DIR__.'/vendor/autoload.php';

use Pyrech\GcodeEstimator\Estimator;

$estimator = new Estimator();
$estimate = $estimator->estimate($absolutePathToGcode);

$estimate->getLength(); // returns the length of filament used (in mm);

You can also estimate the weight and cost of your print by describing the properties of your filament spool:

include __DIR__.'/vendor/autoload.php';

use Pyrech\GcodeEstimator\Estimator;
use Pyrech\GcodeEstimator\Filament;

$filament = new Filament(
    1.75, // filament diameter in mm
    1.24, // filament density in g/cm³
    750,  // weight of the spool in g
    25.99 // price of the spool (whatever your currency)

$estimator = new Estimator();
$estimate = $estimator->estimate($absolutePathToGcode, $filament);

$estimate->getLength(); // returns the length of filament used (in mm);
$estimate->getWeight(); // returns the weight of filament used (in g);
$estimate->getCost();   // returns the cost of filament used (in whatever currency you specified);
