SpoolCast: Filament Dry Guide

Stop guessing whether your filament is too wet to print. SpoolCast checks your local humidity and tells you exactly which spools are safe, which need attention, and which should be dried before use. Every 3D printing enthusiast knows the frustration: bubbling, stringing, and weak layers caused by moisture-absorbed filament. The problem is that each filament type reacts differently to humidity. Nylon absorbs moisture in hours. PLA can last weeks. Keeping track of what needs drying and when is a spreadsheet nightmare. HOW IT WORKS 1. Add your filament spools — select the type (PLA, PETG, Nylon, TPU, ABS, PC, PVA, ASA) and storage status. 2. SpoolCast fetches your local humidity and cross-references it with each filament's moisture tolerance and exposure time. 3. You get a clear status for every spool: GREEN (safe), YELLOW (use soon or re-seal), or RED (dry before use) — plus drying temperature and time for your filament type. It takes 30 seconds to set up. No account required. MOISTURE STATUS DASHBOARD See all your spools at a glance with color-coded status indicators. Each spool shows its current risk level based on today's humidity and how long it has been exposed. One look before you print — no guesswork. FILAMENT DRYING GUIDE Select any filament type and get the recommended drying temperature, duration, and maximum safe temperature. Covers PLA, ABS, ASA, PETG, TPU, PC, Nylon, and PVA with published drying parameters. WEATHER-AWARE TIPS Daily tips based on your local conditions — from "Nylon is safe today" on dry days to "Minimize exposure for all filaments" when humidity spikes. PRO FEATURES Upgrade to Pro for deeper insights: - Unlimited spool inventory (Free: 3 spools) - Exposure timer — tracks how long each spool has been open - Dry history log — record every drying session - Daily humidity trend — 24-hour chart for your location - Dry reminder notifications - Multi-location weather support PRIVACY FIRST All spool data is stored locally on your device. No account, no login, no tracking. Location is used only to fetch weather data from a public weather service (Open-Meteo). Your coordinates are never stored on any server. This app provides general drying guidelines based on published filament data and local weather conditions. It does not measure actual filament moisture content. Always follow your filament manufacturer's specific drying instructions. This app is not a substitute for manufacturer guidance.
