Demo build: items marked [TO FILL] and “Field test pending” are intentional gaps for the operator to complete with real information. See our editorial policy.

Editorial policy

This page explains how LayerMath content is produced and verified. It applies to every guide and calculator on the site. The editor responsible for all content is [TO FILL: author name].

Principles

  1. Show the math. Every calculator output and quantitative claim comes with the underlying formula, units and a worked example.
  2. Cite primary technical documentation. We rely on official firmware documentation (Klipper, Marlin), slicer source documentation (Slic3r, PrusaSlicer, OrcaSlicer), manufacturer polymer technical data sheets (TDS), and established mechanical engineering references.
  3. Distinguish geometry from empirical rules of thumb. Exact relationships (such as lead-screw pitch or polygon chord drop) are distinguished from empirical workshop allowances (such as baseline radial clearances by fit class), and we explain how to verify empirical values with a test print.
  4. Machine and operator safety. We highlight thermal, electrical and ventilation precautions whenever high temperatures, mains-powered beds or styrene/engineering filaments are discussed.

First-hand bench testing

Many 3D printing questions are best illustrated with direct measurements: pin-gauge checks on printed bores, weighed extrusion rate sweeps, moisture weight-loss curves, or plug-in wattmeter logs. Until a bench test has actually been completed, the guide displays a yellow Field test pending box describing the exact measurement protocol to be added. We never write “we measured” or present numbers as our own bench data unless the test has been run, and published test logs will state the printer, nozzle, slicer version, filament and measuring instrument.

Use of software and AI tools

We use software tools, including AI writing assistants, to help with outline organization, first drafts, Python arithmetic verification and copy editing. A human editor is responsible for every published page: checking claims against cited primary docs, verifying every equation and worked example, removing anything that cannot be substantiated, and adding practical context. AI tools are never used to fabricate print logs, caliper measurements, photos, product reviews or author identities.

Updates

Each guide shows its publication date and, when substantively revised, an updated date. Guides are reviewed when firmware or slicer behavior changes, when a reader reports an issue, or at least annually.

Corrections

If you spot an error in an equation, conversion or technical explanation, please report it via the contact page. We verify reports against primary sources, fix confirmed mistakes promptly, and append a dated correction note when an error could have affected a print or design decision.

Independence and funding

LayerMath currently carries no advertising, sponsorships or affiliate links. If advertising is enabled in the future, it will be clearly separated from tools and editorial decisions.
