.STL files are model definition files, describing the surface of a 3D model--they are not "slice' files for feeding a printer. You need to load the .STL fuiles into Chitubox and then after positioning and orienting hem as desired "Slice" the model to produce and save it to a .CTB file. .CTB files contain printer instructions and"slice" images for the printer--copy it to your flash drive for printing...

To speed up app startup time, consider implementing lazy loading techniques. Load only the essential components and data required for the initial screen, and defer the loading of non-essential assets until they are needed. Caching frequently accessed data locally can also reduce response times by minimizing network requests. App Development Process
