Info

You don’t need to be a programmer to understand how to build a pricing script.
Using and modifying the example scripts is actually quite simple.

There are 3 four places in the software where pricing scripts can be used:

Constant Pricing

If a fee or part should be priced the same for all users and for all orders, that can be input a single number into the script. Examples might be a fixed processing cost, a handling fee or a fixed price for internal prototyping in your company.

...

Code Block
languagejs
let cost1 = model.volume * 0.0002; // model.volume in cubic mm
let cost2 = model.area * 0.02;     // model.area in square mm
let price = cost1 + cost2;
price;                             // last line contains final price

Comparison and Relational operators

Name

Syntax

Examples

Equality

x == y

1 == 1; true
0 == 1; false

Inequality

x != y

1 != 2; true
1 != 1; false

Greater than operator

x > y

4 > 3; true

Greater than or equal operator

x >= y

4 >= 3; true
3 >= 3; true

Less than operator

x < y

3 < 4; true

Less than or equal operator

x <= y

3 <= 4; true
3 <= 3; true

Providing Conditions & Discounts

...

Code Block
languagejs
let price = model.volume * 0.0002;  // model.volume in cubic mm

// Add a 10% Discount when ordering more then 10 items
if(item.quantity > 10) {
    price = price * 0.90;
}

// Provide a 5% Discount for Users with a @3yourmind Address
else if(user.email && user.email.endsWith('@3yourmind.com')) {
    price = price * 0.95;
}

// 90$ Discount if price is above 1500
else if(price > 1500) {
    price = price - 90;
}

price; // last line contains final price

Accounting for Additional Costs

Additional costs that are generated by your business can also be accounted for, one of the most common being labor costs for preparing build platforms.

Code Block
let labor = ;                         // € or $
let platformPreparationCost = ;       // € or $

// platform preparation cost is calculated per part

let otherCosts = labor + platformPreparationCost/item.quantity;
