This page contains a listing of available variables under Materials pricing and sample pricing scripts for different technologies.

For a general overview of how Pricing Scripts work, read General Rules for Pricing Scripts.

Variables for Pricing based on Material

This listing are all variables that are derived from each uploaded 3D model.

Variable	Description
`model.volume`	Volume of the 3D model in mm³
`model.area`	Area of the 3D model in mm²
`model.h`	Height of the 3D model in mm
`model.w`	Width of the 3D model in mm
`model.d`	Depth of the 3D model in mm
`model.shells`	Number of separated shells in 3D model
`model.box`	Bounding box volume of the 3D model in mm³
`model.machine_volume`	Convex hull volume of the model in mm³
`support.volume`	Volume of the solid support structures in mm³
`support.area`	Area of the model connected to support structures in mm²
`item.quantity`	Quantity of the same geometry in the basket. (Because the pricing script define a unit price, this variable is needed for quantity-based discounts.
User Properties	See the variable listing under User Based Pricing

Sample Material Pricing Scripts

This section contains sample scripts based on specific technologies and materials.
These pricing scripts can be copied directly into the platform and the variables can be adjusted according to your specific workflow and pricing.

SLS (PA12)

let maxVolume = 380 * 284 * 380; // dimensions of the printer
let materialCost = 60;           // euro/kg
let density = 1.02;              // g/cm^3
let machineRate = 50;            // euro/hour
let maxPrintTime = 14;           // printing time of a full building chamber
let margin = 5;                  // total price is multiplied with margin

// Price calculation
let material = model.volume * materialCost * density * 0.000001;
let time = model.machine_volume * maxPrintTime / maxVolume * machineRate;
let price = margin * (material + time);

SLA (Accura ClearVue)

let maxXYSurface = 650 * 750;    // dimensions of the printer
let materialCost = 120;          // euro/kg
let density = 1.12;              // g/cm^3
let machineRate = 32;            // euro/hour
let timePerSurface = 0.00001;    // h/mm^2 model’s surface
let margin = 5;                  // total price is multiplied with margin

// Price calculation
let material = (model.volume + support.volume * 0.1) * materialCost * density * 0.000001;
let time = model.area * timePerSurface * machineRate;
let price = margin * (material + time);

DMLS (Aluminum ALSI10MG)

let materialCost = 180;        //euro/kg
let density = 4.43;            //g/cm^3
let hourlyRate = 35;           //euro/hour
let scanningSpeed = 3000;      //mm/s
let laserDiameter = 0.1;       //mm
let layerHeight = 0.1;         //mm
let layerPreparationTime = 10; //s
let modelInfill = 0.2;         // 20%
let supportInfill = 0.1;       // 10%

let factor = 1;

// Price calculation
let machineTime = factor * ((model.volume + support.volume * supportInfill) / (scanningSpeed * laserDiameter * layerHeight) + layerPreparationTime * model.h / layerHeight / item.quantity) / 3600;
let price = hourlyRate * machineTime + density * (model.volume + supportInfill * support.volume) * materialCost / 1000000;
