    Description, as the server wrote it
    Use this when someone attaches an STL, 3MF, STEP or OBJ file and wants to know whether it will 3D print well: size, walls, mesh problems and what to change. It reads the file, runs the same automatic design checks as our website, and stores nothing. It gives no quote. When no file is attached, it returns a link to upload the file on our website.

      What this check looks for
    Description, as the server wrote it
    Use this when someone asks how much it costs to 3D print a part, or wants a quote to have a 3D model (an STL, 3MF, STEP or OBJ file) printed and shipped by 3D Printer on Demand. It reads the attached file, checks that it can be printed, saves the quote, and returns the estimate with a private link that opens the saved quote on our website. When no file is attached, or the file type cannot be read, it returns a link to upload the file on our website. It does not cover drawings or photos.

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use this when someone wants help choosing which of our plastics suits a part, from where it will be used: indoor or outdoor, heat, impact, flexing, chemicals, looks and material cost. It returns the materials we offer that fit, best match first, the reasons in plain words, and the ones ruled out and why. It does not rank materials by strength or stiffness, and it sends safety-critical parts to a person.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Use this when someone wants the same parts again from an earlier 3D Printer on Demand order. It takes the private order link from their order email, works out a new estimate for each part from the files saved with that order, and returns a private link to review the parts and order them on our website. It takes no payment and does not change the earlier order.

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Use this when someone asks what clearance or hole size to draw for a printed fit: a sliding part, a bolt or pin through a hole, two printed parts that mate, a press fit, or a snap fit. It returns published starting clearances and hole guidance, each with its source, and how to test the fit. It gives no single universal hole offset, because none is published.

    • destructiveHint: false

  • update_print_quoteUse this when someone wants a different quantity or color on a quote 3D Printer on Demand already gave them.No findings

    Why it is in this group

    • The name "update_print_quote" says "update": a word for a change.
    Description, as the server wrote it
    Use this when someone wants a different quantity or color on a quote 3D Printer on Demand already gave them. It takes that quote's private link and the new quantity, works out the estimate again from the file saved with the quote, saves it, and returns the new estimate with a new private link. The earlier link keeps the earlier quote. It does not take a new file, a different material, or a link that did not come from one of our quotes.

    Why it is in this group

    • The name "compare_print_vs_molding" says "compare": a word for reading.
    Description, as the server wrote it
    Use this when someone wants to compare 3D printing with injection molding for a quantity, using their own numbers: quantity, printed unit cost, tooling cost and molded unit cost. It returns the totals for each, the crossover quantity on those numbers, and the published range with sources. It makes up no cost, and when a number is missing it says which.

    Why it is in this group

    • The name "get_design_guidance" says "get": a word for reading.
    Description, as the server wrote it
    Use this when someone asks how to design a part for FDM 3D printing: wall thickness, tolerances, hole clearances, overhangs and supports, orientation, infill, bosses, ribs, snap fits, threaded inserts, dimensional accuracy, published material figures, or printing compared with molding or machining. It takes a topic or the question and returns short answers with their published sources and a link to the full page. It does not check a specific file.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false

    Why it is in this group

    • The name "get_order_status" says "get": a word for reading.
    Description, as the server wrote it
    Use this when someone who ordered from 3D Printer on Demand asks where their order is or what state it is in. It takes the private order link from their order email and returns the order's status, its parts, how many have shipped, and any tracking numbers. It does not show the shipping address and it does not change the order.

    Why it is in this group

    • The name "get_service_details" says "get": a word for reading.
    Description, as the server wrote it
    Use this when someone asks how 3D Printer on Demand works: lead time, shipping, how long a quote is held, accepted file types, the largest part, the items we refuse to print, or where to upload a file, request a review or get in touch. It returns these facts as our website publishes them.

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false
  • list_materialsUse this when someone asks which plastics 3D Printer on Demand prints, which colors each comes in, which material suits a job, or which materials are quoted by a person.No findings

    Why it is in this group

    • The name "list_materials" says "list": a word for reading.
    Description, as the server wrote it
    Use this when someone asks which plastics 3D Printer on Demand prints, which colors each comes in, which material suits a job, or which materials are quoted by a person. It returns each material with what it is for, what it is not advised for, its colors and how it is quoted, plus plain guidance on comparing them. It returns no engineering figures.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
