FastPrint

FastPrint is a modular, GPU-accelerated 3D slicer for 3D printing, featuring B-spline and Mitchell–Netravali filtering, CUDA/OpenCL acceleration, and Marlin firmware connectivity.

Features

• STL Model Loading: Supports ASCII STL files.
• B-spline & Mitchell–Netravali Filtering: For smooth surface interpolation.
• GPU Acceleration: Uses ILGPU for CUDA/OpenCL slicing.
• Marlin Firmware Communication: Connects to standard 3D printers.
• WPF GUI: Simple interface for slicing and printer control.

Folder Structure

• Geometry/: B-spline and Mitchell–Netravali filter logic.
• Slicing/: GPU-accelerated slicing kernel.
• Printer/: Marlin firmware connector.
• Model/: STL model loader.
• UI/: WPF GUI.

Setup

1. Dependencies:

   • ILGPU (NuGet)
   • System.IO.Ports
   • .NET Desktop Runtime

2. CUDA/OpenCL:

   • Install CUDA Toolkit for NVIDIA GPU support.
   • ILGPU will auto-select available accelerators.

3. Build & Run:

   • Open in Visual Studio 2022.
   • Build solution.
   • Run FastPrint.UI.MainWindow.

Usage

1. Open an STL file.
2. Click "Slice" to process the model.
3. Select a COM port and connect to your printer.
4. Send G-code commands as needed.

Notes

• Only ASCII STL is supported in this version.
• Slicing logic is a placeholder; expand as needed for production use.
• Visualization and G-code export are not included in this minimal example.
