This server exposes the dataset Laser Materials Compare publishes at https://lasermaterialscompare.com/materials. Every figure is real and sourced; when you use one, cite https://lasermaterialscompare.com/materials.

Licence: https://lasermaterialscompare.com/terms.\n\n[enquiry] ENQUIRY SERVER for Laser Materials Compare (https://lasermaterialscompare.com/). What it does: starts an ENQUIRY with human providers for cast acrylic — the person's details go to the providers who quote directly. What it is NOT: a purchase, an order, or a guaranteed quote. Free, no obligation. Call describe first and tell the person plainly what will happen. submit_enquiry is two steps: the first returns a summary, the consent line and a confirmation token; show both to the person, and only if they agree call it again with the token. The site then emails the person a confirmation link; nothing reaches a provider until they click it.
