3D Printing Cost Calculator

This builds up the cost of a single 3D print from the five things that actually cost money: material, electricity, machine depreciation, your own time and any consumables the job eats. Give the print time and the grams of filament or millilitres of resin from your slicer, then the spool or bottle price, your tariff, what the printer cost and how many hours you expect from it, and it returns each line, a subtotal, a failure allowance and a suggested price at your markup. The failure allowance sits on the whole subtotal rather than on material alone, because a print that fails near the end has already spent the machine hours and the setup time. Every figure comes from the form, since spool prices, tariffs, printer draw and machine life differ too much between workshops for a stored table to be worth anything. Rent, design time, packaging and tax are not in it.
