Ever forget the printing temperature range for certain types of filament? Filadex is basically a reference app for different kinds of 3D printing filaments. It can relay information such as extruder and bed temperatures as well as pros and cons about different types of filament. To use, first launch the application by saying "Alexa, open Filadex." Then you can ask questions such as "What is the printing temperature for PLA?" or "What are some downsides to ABS?"
