D&L ENGINEERING TOOLS - PQ-01 DIGITAL FILE LICENCE
Version 1.0 - 22 October 2026

PERMITTED USE
The supplied PQ-01 STL and 3MF files may be used free of charge for personal use and internal business use, including printing qualification coupons for the user's own printers and internal process-development activities.

DIGITAL FILE RESTRICTIONS
The digital files may not be redistributed, uploaded to third-party repositories, shared, sublicensed, resold, repackaged or included in another digital product without written permission from D&L Design Engineering.

PRINTED COPY RESTRICTIONS
Printed copies may not be manufactured for resale or supplied as a commercial printed product without a separate commercial manufacturing licence from D&L Design Engineering.

ENGINEERING LIMITATION
PQ-01 is an engineering process-characterisation aid. It is not a calibrated metrology standard, certified reference artefact or product-conformity standard. A single coupon does not establish formal process capability. Measurement uncertainty, printer condition, material, build position, slicer settings and inspection method must be considered when applying results to production work.

NO WARRANTY
The files are supplied as-is. Users remain responsible for determining whether the artefact and measurement method are suitable for their application.
