PQ-01 v1.2 coupon
STL and 3MF geometry with holes, pins, thin walls, Z-height features, reference blocks and larger geometric checks.
Digital engineering pack
PQ-01 Professional Qualification Pack
A controlled workflow for characterising dimensional behaviour, comparing printer configurations and recording an engineering qualification decision.

Professional-use licence included. Digital product; no physical coupon is supplied. £14.95 is the advertised VAT-inclusive checkout price where applicable.
Why it exists
A calibration print is only useful if the result changes a decision.
Visual test prints can show that a printer is working, but engineering use needs a defined requirement, repeatable measurement and a recorded decision. PQ-01 Professional turns the existing PQ-01 coupon into a controlled qualification workflow.
No universal tolerance is imposed.
The workbook intentionally leaves acceptance limits blank until you define the actual requirement basis. That might be a drawing tolerance, internal process target or project-specific acceptance criterion.
Inside the pack
Everything needed to run and record the check.
Qualification procedure
A controlled six-page procedure defining scope, preparation, measurement, acceptance and reporting workflow.
Measurement guide
Five-page reference showing how the PQ-01 features are intended to be measured consistently.
Automated workbook
Six configurable sample sheets plus summary calculations for error, repeat range, failures, MAE and overall status.
Report template
Editable Word qualification report with PDF reference copy for recording scope, configuration, evidence and disposition.
Example data
Validated three-configuration dataset showing how results can be compared and summarised.
Preview
Built as an engineering system, not a loose collection of files.
Workflow
Four steps from print to decision.
Define
Set the acceptance limits and requirement basis before judging the print.
Slice the supplied coupon at 100% scale using the production profile you want to characterise.
Measure
Take three reseated measurements per feature using the supplied measurement guidance.
Decide
Review failures, MAE, repeat range and configuration differences, then record the engineering disposition.
Professional licence
Use it in real engineering work.
The purchaser may print unlimited PQ-01 coupons for their own facilities and projects, use the workbook and report template in paid engineering work, modify internal copies and provide clients with derived results and completed reports.
The reusable source files themselves may not be redistributed, resold or bundled into another digital product.

Important scope
What PQ-01 does not claim.
PQ-01 is printed by the process under test, so it cannot replace calibrated dimensional standards or traceable artefacts.
A single coupon or small sample does not establish Cpk/Ppk or long-term manufacturing capability.
The tool deliberately requires the user to define acceptable deviation for the intended application.
Passing PQ-01 does not certify a printer, filament, production process or final part for any regulated use.
FAQ
Before you buy
Does PQ-01 set a universal 3D-printing tolerance?
No. Acceptance limits are user-defined because suitability depends on the actual requirement, material, geometry, printer and process.
Is PQ-01 a calibrated reference artefact?
No. It is an engineering process-characterisation aid, not a calibrated metrology standard or certified reference artefact.
Can I use it for client work?
Yes. The Professional licence permits paid engineering work and completed client reports containing derived results. Reusable source files cannot be passed to a client unless they hold their own licence.
What software do I need?
A slicer capable of STL or 3MF files, a spreadsheet application compatible with XLSX, and a PDF reader. The report template is supplied as DOCX and PDF.
Is a STEP file included?
No. Version 1.0 contains the controlled STL and 3MF coupon files. A mesh-to-STEP conversion has deliberately not been included because it would not provide a genuine native CAD model.
What happens if the digital files are faulty or do not match the description?
Your statutory rights are not excluded. Contact D&L Design Engineering so the issue can be investigated and an appropriate remedy provided.
