How it works
Use slicer weight including supports and purge, then add only uncounted waste. Machine time is your chosen allowance for wear and capacity. Hands-on labor is entered in minutes, separate from unattended print hours.
Material = grams ÷ 1,000 × price/kg × (1 + waste allowance)
Energy = watts ÷ 1,000 × hours × electricity price
Cost = material + energy + machine time + hands-on labor + other costs
Quote = cost ÷ (1 − target margin)

A few useful details
Is margin the same as markup?
No. At 30% margin, divide cost by 0.70. Multiplying cost by 1.30 produces a 30% markup instead.
Should all print hours count as labor?
Not in this model. Unattended time uses the machine allowance; hands-on setup and finishing use the labor field.
Do I need an account?
No. This release runs without an account, API key or payment. Saving a favorite stores only the tool’s identifier in this browser, not your inputs.

Cost → quote → order profit
A worked quote for one printed item.
The starter job uses 100 g at $20/kg with 10% extra material ($2.20), 5 hours at 120 W and $0.15/kWh ($0.09), a $0.50/hour machine allowance ($2.50), and 15 hands-on minutes at $20/hour ($5.00). Total modeled cost is $9.79.
A 30% target gross margin gives $9.79 ÷ 0.70 = $13.99 when displayed to cents. This quote is before selling fees and shipping, and cent rounding can slightly change the achieved margin. A failed full print can repeat machine time and labor too; the material-waste percentage does not cover that risk.
For a batch, enter the whole job consistently and divide its total cost by the number of saleable units before estimating profit on one sale. Save a named project for the quote; use batch CSV for separate jobs. Each CSV row remains an independent job.

- Build a full print quote — material, power, machine time and hands-on labor.
- Check order profit — selling fees, packaging and delivery.
