what other calculators don't have

Not a prettier spreadsheet. A system that works for you.

Three things no spreadsheet does.

return per machine

Stop guessing which machine makes money

Every printer has a cost and earns revenue from the orders it produces. The system crosses the two and shows the real return of each one. You know which machine is paying off, no guesswork.

batches, kits, B2B orders

No more spreadsheet for every order

A business order with 12 parts, 3 models and 2 colors? Add each part and get one quote with the right material, time and cost. No side spreadsheet, no math in your head.

link, accept, print

Quotes your customers can accept online

Every quote gets its own public link with your logo and company details. Your customer opens it in the browser, accepts it or asks for changes, and it lands on your orders board. They never need an account.

what goes into the price

It's not just filament.
It's five other costs you forget.

Every cost has its own color in Plataforma Stratta. You see at a glance what weighs on your price and what is quietly eating your margin.

Filament

What actually becomes the part.

Part weight times spool price. It sounds simple, but two details catch people: account for purge waste (every color change burns filament that never reaches the part) and add the expected failures (10 g becomes 11 g if you allow a 10% chance of a failed print).

classic mistake

A maker buys an expensive imported spool and keeps using the same cost per gram as basic PLA.

Energy

Printers don't run for free.

Printer power in kW times print time times your rate per kWh. On a small part it's pennies. On a farm of 3 machines running 12 hours a day, it becomes an electric bill that scares you at the end of the month.

classic mistake

A maker printing from home who never sees the power bill climb until it arrives.

Labor

Your HUMAN time. Not the printer's.

What it costs to slice the STL, load the plate, remove the part, inspect it and pack it. It's per JOB, not per print hour. A 2-hour keychain takes 5 minutes of labor. A big 10-hour part takes 15. The machine works alone; you don't.

classic mistake

A maker who charges $15/h for the 4 hours a part sat on the printer, then loses the customer because the price came out too high.

Depreciation

The machine is worth less every hour.

Price paid divided by service life in hours. A $399 printer / 10,000 h = $0.04/h. A Bambu Lab X1 Carbon at $1,199 / 12,000 h = $0.10/h. That value multiplies the print time. It isn't money leaving your pocket NOW, but it's money you need to set aside to replace the printer when it dies.

classic mistake

A maker who financed a printer, never included depreciation, and had no cash to replace it when the time came.

Maintenance

Hotends burn out. Plates get dented. Bearings seize.

Average cost of parts, lubricants, FEP, hotend, fans and sensors. For a desktop printer it comes to roughly $0.04 to $0.06 per hour. Not every print needs it, but in aggregate the math works out.

classic mistake

A maker who replaces a $20 hotend and doesn't charge anyone to cover it.

Accessories and packaging

Everything that ships with the part.

Keychain rings, magnets, screws, tape, LEDs, cords, stickers, plus packaging (small box, tissue paper, bubble wrap, envelope). On a keychain it's a few cents. On a decorative kit with 5 items, it becomes the second-biggest cost of the project. Plataforma Stratta calculates it per piece or spread across the whole project.

classic mistake

A maker who charges only for the print and finds out at the end of the month that $50 went to rings and tissue paper with nothing passed on.

same keychain, 3 prices

Guessing your price
means working for free.

Same part (a 187 g keychain on a K1C, 4 h 10 min print), 3 ways to price it. Look at the margin difference.

loss
I guessed
$3 · because that's what it sells for online
$3.00
-108% margin · -$3.25 per piece
-100%0+100%

You spent $6.25 making it (filament, electricity, labor, depreciation, maintenance). You charged $3 because you saw it listed that way online. Every piece you sell takes $3.25 out of your pocket. By the end of the month you've sold 60 pieces and you're $195 down.

thin margin
I went with my gut
$7 · 'my cost is about $3'
$7.00
+11% margin · +$0.75 per piece
-100%0+100%

You estimated material and electricity, and forgot real labor, printer depreciation and failure rate. Your margin is about $0.75 before taxes. It pays the bills, but leaves nothing to reinvest or to replace the printer.

healthy margin
I ran the numbers
$11.25 · everything added up, 1.8x markup
$11.25
+44% margin · +$5.00 per piece
-100%0+100%

Material, electricity, project labor, depreciation, maintenance, expected failures and markup. A 44% margin. Enough to grow, replace the machine and sleep easy.

Real cost to make this part: $6.25. Any price below that is a direct loss. Plataforma Stratta works out that number for you once you add your printer, filament and costs.
