How do I find my printer's wattage?

Start with the preset. Infill ships profiles for common machines — Bambu Lab, Prusa, Creality, Elegoo, Anycubic — and those numbers are the average draw while printing, which is what actually determines your electricity bill.

Do not use the number printed on the power supply or in the spec sheet. That is the peak: it is what the machine pulls with the bed heater at full tilt during warm-up, and heaters spend most of a print switched off. A printer rated at 350 W typically averages nearer 110 W over a long print, so using the nameplate figure can overstate your electricity cost threefold.

If you want your own figure, a plug-in energy meter is the honest way: run a normal print, note the kilowatt-hours used, and divide by the print time in hours to get average kilowatts. Times 1000 gives the watts Infill wants. If your machine is not in the list, pick Other printer and edit it.

What is the difference between margin and markup?

They are measured against different things, and the gap gets embarrassing quickly.

Markup is a percentage of your cost. A 50 % markup on a €12.00 print means €12.00 × 1.5 = €18.00.

Margin is a percentage of your selling price. A 50 % margin means half of what the buyer pays is profit, so the price is €12.00 ÷ 0.5 = €24.00.

A 50 % markup is only a 33 % margin. Plenty of calculators multiply by 1 + your number and label the result “margin”, which quietly undercharges you. Infill makes you pick which one you mean, applies the right formula, and then shows you the effective margin on the finished quote so you can check the number means what you thought.

Why is my price higher than in other calculators?

Usually for one of five reasons, and all five are Infill being correct rather than greedy:

• Margin, not markup. See above. At 50 % this alone is a 33 % difference.
• Failed prints are divided, not added. If 20 % of prints fail you need 1 ÷ 0.8 = 1.25 attempts on average to deliver one good part, not 1.2. Adding 20 % on top leaves you covering the difference yourself.
• Marketplace fees come off the selling price. Etsy's cut is a percentage of what the buyer pays, not of your cost. Infill solves for the price so the fee does not eat your margin.
• Machine cost is real. Infill charges depreciation and maintenance per print hour. A €699 printer over 6,000 hours is about 12 cents an hour before consumables. Most calculators ignore it, so their prices slowly consume the printer.
• Your time is in there. Levelling, removing the part, cleaning supports and packing are hands-on minutes at your hourly rate. On small prints, labour is usually the largest single line.

If you genuinely want to quote lower, the honest lever is not a broken formula: use the Who is asking? switch, or lower your margin explicitly, so you can see exactly what you gave away.

How do I set up Etsy fees?

Open Settings, then under Shop use Selling on and pick Etsy. Infill ships published fee schedules for Etsy, eBay, Shopify and Amazon Handmade. They are fixed in this version — you cannot edit the individual rates yet. Fee schedules change and differ by country, so check the figure against your own seller terms before you rely on it.

With a marketplace selected, Infill stops treating the fee as a cost and solves the price equation instead: it works out the listing price at which, after the platform takes its cut, what lands in your account still delivers the profit you asked for. The quote shows the fee as its own line so you can see what the platform is taking.

Marketplace fees are an Infill Pro feature. The free version always prices as a direct sale, with no platform cut — the Selling on picker only appears once Pro is unlocked, so there is nothing to switch off.

How do I restore my purchase?

Infill Pro is a one-time purchase tied to your Apple Account, so it follows you to a new device or a reinstall at no extra cost.

Open the Pro screen in the app — from Settings, or by tapping any Pro feature — and tap Restore purchase. Make sure the device is signed in to the same Apple Account you bought with, and is online. The unlock is normally instant.

If it does not restore: check iOS Settings → your name → Media & Purchases to confirm which account you are signed in with, then try again. If it still fails, email levin.schwab@gmx.de. Apple does not tell the developer who bought what, so please include the App Store receipt from your emailed invoice; it makes it possible to help you properly.

Is my data backed up?

Not by the developer — there is no cloud service behind Infill and no server holding a copy of your prices. That is deliberate, and it is also the tradeoff: nobody can read your data, and nobody can recover it for you.

It is covered by your device's own backup. Infill stores everything in the app's private container, which iOS includes in an encrypted iCloud Backup or a local computer backup. Restore that backup onto a new device and your printers, materials and saved quotes come back with it.

Deleting the app deletes the data with it, so if you are about to reinstall, make sure you have a backup first. Infill Pro can also export your saved quotes as CSV, which is a good habit for bookkeeping and doubles as a copy you control. Full details in the privacy policy.
