Infill

Terms of Use

Last updated: 16 August 2026

These terms apply to Infill: 3D Print Cost Calc (“Infill”, “the app”), an app for iPhone and iPad made by Levin Schwab. Installing or using the app means you accept them.

Licence

Infill is licensed, not sold. Your licence is Apple's Licensed Application End User License Agreement (the “Standard EULA”), which applies in full unless a term below is more favourable to you. In short, you get a personal, non-transferable licence to use Infill on Apple devices you own or control, in line with the App Store Terms of Service.

Apple is not a party to these terms and has no obligation to provide support for the app. Apple is a third-party beneficiary of the Standard EULA and may enforce it.

Infill Pro

Infill Pro is a one-time in-app purchase. It is not a subscription, nothing renews, and nothing will be charged again. It unlocks unlimited printers and materials, marketplace fees, tax, unlimited saved quotes and CSV export.

The purchase is tied to your Apple Account and can be restored on any device signed in with that account using Restore purchase in the app. Payment is processed by Apple; the developer receives no payment details.

Refunds

All App Store purchases are handled by Apple, so refunds are requested from Apple, not from the developer, at reportaproblem.apple.com. Statutory rights of withdrawal and consumer protections in your country are unaffected. If something is broken, email first — a fix is usually quicker than a refund.

Estimates, not advice

This matters more than the rest of this page. Infill is a calculator: it applies arithmetic to numbers you enter. The output is an estimate, and its accuracy depends entirely on the accuracy of your inputs.

  • Bundled printer, material, electricity and marketplace figures are typical starting points, not verified facts about your machine, your supplier, your tariff or your seller account. Check them and edit them.
  • Marketplace fee schedules change and differ by country and seller status. The figures in the app were reasonable when written; check them against your own seller terms before relying on a quote.
  • Tax handling is a simple percentage on top of the price. It is not tax advice and does not account for registration thresholds, reverse-charge rules, exemptions or anything else specific to your situation.
  • Pricing, invoicing, tax, warranty and consumer-law obligations towards your own customers remain entirely yours.

Do not use Infill as your only basis for a binding quote without checking the figures. The developer is not liable for lost profit, mispriced work or any other loss arising from relying on the app's output, to the extent the law permits such a limitation. Nothing here excludes liability for intent, gross negligence, or personal injury, or any liability that cannot lawfully be excluded.

Availability and changes

Infill is provided as it is, without any guarantee of uninterrupted availability. Features may be added, changed or removed in future versions. If a change materially affects Infill Pro, it will be described in the App Store release notes. Existing Pro purchases will not be converted into a subscription.

Acceptable use

Do not reverse-engineer, decompile or redistribute the app except where the law expressly allows it, and do not use it in breach of the App Store Terms of Service.

Trademarks

Printer, filament and marketplace names appear in Infill only to identify preset configurations. Infill is not affiliated with, endorsed by or sponsored by Bambu Lab, Prusa Research, Creality, Elegoo, Anycubic, Etsy, eBay, Shopify, Amazon, Google or Apple. All trademarks belong to their respective owners.

Governing law

German law applies, excluding its conflict-of-law rules. If you are a consumer, this does not deprive you of the protection of mandatory provisions of the law of the country where you live.
