Filament Lager

Reads and writes OpenPrintTag tags – the open NFC tags on filament spools, e.g. from Prusament. Hold your iPhone to the spool, and Filament Lager shows material, color, temperatures and how much is left. All spools go into your inventory – with remaining amount, slot and purchase price, synced to all your devices via iCloud if you like. STATISTICS How much filament is on your shelf, what is it worth, and how much do you print per week or month? Statistics show your stock by material, when a material is likely to run out at your usage, which colors and brands you use most – and your whole shelf at a glance, with the remaining amount of every spool. INVENTORIES & SHARING Organize your spools by place, e.g. Workshop and Home – each inventory with its own icon and color. Share an inventory via link or invitation and decide for each person whether they can edit spools or only view them. Spools move to another inventory with one tap. WRITE BLANK TAGS Write new or reused tags right in the app: pick brand and filament from the open material database – more than 120 brands, favorites on top – choose the spool, done. If your filament is missing, add it yourself with color and temperatures. When a spool is empty, erase the tag and use it for the next one. Spools without a tag can be added just as easily. KEEP TRACK OF USAGE Enter the remaining amount, subtract grams used or simply put the spool on a kitchen scale – empty spool weights of many manufacturers are built in, and printed tag adapters are counted too. Picked the wrong spool? Undo the last entry. After a multicolor print, scan all spools in one go. The app writes slot and usage back to the tag, so printers and other apps see the same state. SIRI & SHORTCUTS Ask “How much PETG do I have in Filament Lager?” – or use stock and remaining amount in your own automations. ORDER ON THE SHELF The slot overview shows what is on which shelf. The Home Screen widget tells you which spools are running low. DRYING Recommended drying values per material, a timer with notification and the date each spool was last dried. IMPORT & EXPORT Backup as a file, spreadsheet for Excel or Numbers – and back. Available in English and German. Light, dark or system appearance.
