3DCP Global Project Database 2015–2026

The Excel file has five sheets. The README sheet mirrors the README.txt so the workbook is self-contained. The Master Database has all 92 projects across 24 clean fields with consistent formatting: dashes are light grey, approximate values are amber-tinted, alternating row bands make scanning easy, and the header row is frozen. The Codebook defines every field with data type, unit, controlled vocabulary, and missing-data rules — this is what Zenodo reviewers and future users need most. The Correction Log is reformatted cleanly with ERROR/WARNING colour coding. The Summary Statistics sheet has pre-computed counts by year, sector, country, printer type, and fabrication strategy.
