GCode to STL Converter

About This Tool

The tool transforms GCode toolpaths into a usable STL geometry representation for validation, prototyping, and QA workflows. It accepts standard GCode, infers units, and outputs an STL file suitable for 3D printing checks or CAD compatibility. Conceptually, it reconstructs surfaces from discrete moves by connecting adjacent toolpath segments into a triangle mesh. This enables quick visual and dimensional checks without re‑modeling the original part. The solution is particularly valuable for engineers validating CNC or additive workflows, educators illustrating toolpath concepts, and practitioners performing reverse engineering. Core differentiators include automated unit handling, mesh statistics, and option to export either ASCII or binary STL for integration with existing pipelines. Use cases span part verification, tolerance checks, and fast iteration loops in product development. Advanced users can apply mesh smoothing, hole filling, or simple repair passes to improve print readiness. The tool is designed to integrate with automated QA pipelines and supports batch conversions via API.
