FOR AGENTS / START HERE

Build hardware.
Start with advice.

Use PrintRelay when you need manufacturing knowledge or your CAD is ready for its next step. Keep the geometry, requirements and evidence together.

Advice, CAD checks and nonbinding review requests are live.
Supplier purchasing, payments and fulfillment are disabled.

01 / CHOOSE YOUR NEXT ACTION

From a question
to an exact handoff.

Start with knowledge. Connect an account when you need private CAD, saved specifications or a review request.

  1. 01

    Ask before you design.

    Get sourced guidance on fits, materials, meshes, FDM, SLS and cost drivers. No account or CAD needed.

  2. 02

    Bring the exact part.

    Upload authorized CAD with explicit units. Read measured STL geometry, then pin process, material grade, finish and manufacturing settings.

    ACCOUNT REQUIRED
  3. 03

    Explore the constraints.

    Read preliminary DFM risks and limited planning ranges for the saved specification. Immediate analysis is rule based; budget ranges are uncalibrated and exclude shipping and tax.

  4. 04

    Ask a specialist. Track the answer.

    Submit your engineering question as a free DFM review request. Resume by order ID to read the asynchronous advisory report. No turnaround guarantee.

Need a supplier quote or manufacturing?

You can submit a nonbinding quotation or manufacturing request. The quote queue and comparison engine are available, but collecting real supplier evidence still needs an authenticated buyer session and operator browser access. A queued request is not a price or production commitment.

03 / PRESERVE THE INTENT

Carry these through every step.

Exact identity
Keep the request ID, CAD SHA-256 and specification fingerprint. Changes to manufacturing requirements need a new specification.
Safe retries
Reuse the same idempotency key with identical inputs after a timeout. Reconcile an existing request before creating another.
Explicit permission
CAD upload and sharing with named suppliers need separate authorization. A backlog request does not authorize payment, purchase or printing.
Evidence and unknowns
Preflight is not printability certification. Planning ranges are not supplier quotes. Report missing inputs and unknown costs without guessing.

INSPECT BEFORE YOU INTEGRATE

Start with a real geometry report.

A measured 20 mm calibration cube and an enclosure tutorial show the handoff format. Examples are not customer orders or supplier quotes.
