About KatMon

KatMon is an all-in-one digital toolbox designed for 3D printer users and makers to streamline every step of the production process. More than just a filament management tool, it is a smart ecosystem that brings artificial intelligence, creator networking, STL analysis, and printer maintenance monitoring right to your pocket—keeping your 3D printing workflow controlled, layer by layer. Key Features: Smart Filament Calculator & Inventory Management: Accurately calculate remaining filament weight using our comprehensive empty spool database, and track your entire inventory with zero errors. STL Viewer & Material Analysis: Preview your 3D models directly within the app, and calculate volume, weight, and material costs before sending them to print. Gemini AI-Powered Assistant: Get instant solutions for print failures, slicing configurations, and technical troubleshooting from a dedicated 3D printing AI companion. Maker Network: Connect with fellow makers, showcase your latest 3D prints, share slicer profiles, and solve technical challenges together with the community. Maintenance Monitor & Scheduler: Never forget nozzle replacements, belt tensioning, or rod lubrication. Extend your printer's lifespan with customized maintenance alerts. 3D Printing News & Tech Trends: Stay up to date with the latest industry innovations, new filament releases, and community updates. Spool Tower Mini-Game: Pass the time while waiting for your long prints to finish with a fun, maker-themed mini-game. Why KatMon? Varying empty spool weights across brands make guessing remaining filament highly inaccurate. Running out of material mid-print ruins projects, wastes time, and costs money. KatMon eliminates the guesswork by providing powerful calculation tools, a built-in STL preview engine, and advanced AI assistance to make your 3D printing workflow controlled, seamless, and efficient. Start creating with the ultimate digital companion for your 3D printer today!
