This software was developed independently by the Author in personal time, using personal resources. It is not affiliated with, nor a deliverable of, any funded research project or institutional programme.

The 3D Printing Formulator is a standalone desktop application designed to assist researchers and practitioners in formulating ceramic resins and pastes for additive manufacturing. It provides a structured, user-friendly interface for calculating and optimising formulation parameters.

The tool works in two directions:

• Forward Formulator — you decide the amounts, the app calculates the final composition (wt.%, vol.%, mixture density)
• Inverse Solver — you decide the composition you want, the app calculates the amounts for you

Additional features include:

• Built-in Materials Database with ~200 editable entries
• PDF export of results
• Save/Load functionality for recipes
• Blend support with per-constituent mass breakdown on hover
• Merge DB for safe database upgrades
• 10-language user interface
• Comprehensive built-in Help & User Guide

• Bug fixes
• Blend breakdown tooltip — hover over a blend component after Solve to see individual masses
• Merge DB — safely add new default materials without affecting custom entries
• Materials added to the default database
• Materials' properties corrected

See WHATS_NEW.txt for full details.

Two example recipe files from published research are available as a separate download alongside this release:

📦 Example Formulations.zip

Download, extract, and open the .json files using the 📂 Load button in the app. These examples demonstrate typical Inverse Solver workflows for ceramic resin formulations.

If you use these formulations in your own work, please cite the original publications as well as this software.

Your custom materials database is preserved between versions and will not be overwritten when you install a new release.

To receive new default materials added in v1.1:

1. Download materials_database_april_2026.json from the release assets
2. Open the app → click 🗃 Materials DB in the sidebar
3. Click 🔀 Merge DB and select the downloaded file
4. The app adds only new entries — your custom materials are never modified
