Welcome to PrintCore – the high-performance, zero-permission additive fabrication and 3D printing calculation matrix engineered specifically for makers, prototyping engineers, and print farm operators who require reliable computational tracking entirely offline.

PrintCore packs four specialized material and hardware calculation engines onto a clean, single-viewport dashboard panel. Estimate volumetric limits, audit material costs, calibrate scaling factors, and manage production runtimes instantly without relying on active cellular networks or external telemetry data.

🔒 100% OFFLINE & PRIVATE (ZERO PERMISSIONS)
PrintCore runs on a strict, local-first computing framework. The application deliberately excludes the Android Internet Permission (android.permission.INTERNET) from its manifest and requests zero hardware permissions. Your dimensional inputs, material values, and runtime metrics are processed entirely within volatile device system memory and never leave your hardware.

🚀 FOUR CORE FABRICATION ENGINES

1. FILAMENT COST EXTRUDER
Audit the true cost of your prints instantly. Input your raw spool mass, material type (PLA/PETG/ABS/Nylon), market purchase price, and the exact slicer-estimated usage length or weight. The engine immediately isolates the real per-gram physical material cost.

2. VOLUMETRIC FLOW RATE MONITOR
Protect your hardware and prevent hotend jams. Input your layer height, extrusion width, and printing speed. The engine processes these variables to compute your active volumetric flow rate (mm³/s), matching it against your physical hotend limits to ensure reliable extrusion.

3. THERMAL SHRINKAGE RATIOMETER
Achieve high-precision dimensional accuracy. Input the raw target dimensions of your part alongside the specific cooling shrinkage rate of your polymer filament. The application calculates the exact percentage scaling factor required in your slicer to counteract physical cooling contraction.

4. MULTI-BATCH PRODUCTION TIMER
Streamline print farm coordination. Input your layered component print times, hardware cooldown buffers, and manual post-processing tasks. The tool aggregates the timelines to estimate your complete end-to-end multi-part run allocations.

IMPORTANT NOTICE:
PrintCore is a mathematical reference utility. All calculations are approximations based strictly on user-supplied manual inputs. These outputs do not substitute for official slicer software logs, active hardware firmware limits, or physical testing. The fabrication operator holds absolute responsibility for monitoring hardware safety.
