Ellison Grant is the named editorial contact for technology and 3D printing content, including calculator hardware, digital-tool comparisons, print materials, electricity costs, and pricing assumptions. This profile describes assigned topic coverage, not an engineering credential or manufacturer affiliation.
Printing estimates depend on material consumption, machine time, electricity prices, labor, and any failure allowance. Hardware features, testing rules, and product prices should be confirmed with the manufacturer or relevant official source.
Editorial attribution does not establish independent product testing or professional certification. Questions and correction reports can be submitted through the contact page with the relevant article or calculator link.
