Quality control
Quality and Inspection
Metal3D.ai is built around engineer-reviewed quotes, clear requirements, partner factory coordination, and practical inspection records for custom metal parts.
Quality Commitments Before Production
Quality starts at RFQ intake. The platform is designed to keep quote assumptions visible before a customer pays.
Engineer-Reviewed Scope
Every complete RFQ is checked for material, process, tolerance, finish, inspection, and shipping assumptions before quote release.
Quote Exceptions Are Visible
Unclear drawings, missing datums, unsupported finishes, or compliance questions are surfaced instead of hidden in a generic price.
Order Timeline Records
Accepted quotes move through order, production, QC, shipment, and delivery events so teams can audit progress.
Inspection Options
Standard Visual Check
Basic review for obvious defects, finish issues, and packing readiness.
Dimensional Spot Check
Selected critical dimensions can be checked when drawings identify them clearly.
Advanced Reports
CMM, material certificate, and first article inspection can be quoted when available.
Report Sample Review
For inspection-heavy RFQs, quote notes can specify sample report format, measured dimensions, certificate needs, and shipment document expectations.
Production Documentation
Approved Quote
Scope, inclusions, exclusions, DFM notes, lead time, and shipping assumptions.
Customer Files
CAD models, drawings, and references are stored privately for quote and production use.
Shipment Records
Carrier, tracking, declared value, destination, shipped date, and delivered date.
NDA and File Security
CAD files and drawings are treated as private RFQ assets. The system stores uploaded files in private storage keys and logs administrative downloads.
NDA Request at Intake
Customers can request an NDA before detailed engineering review or supplier sharing.
Private File Storage
RFQ files are stored with UUID-based private keys, not public URLs or quote numbers.
Download Audit Trail
Administrative CAD downloads are recorded with requester context for IP-sensitive RFQs.
Scan Gate Before Sharing
Uploaded files are checked for extension, declared MIME, magic headers, archive structure, and optional virus-scan status before download or partner handoff.
Quote Turnaround Targets
Complete RFQs are targeted for initial engineering triage within 1 business day. Formal quote timing depends on DFM questions, supplier capability confirmation, inspection scope, and shipping assumptions.
Complete RFQ
CAD model, drawing for critical dimensions, material, quantity, finish, destination, and use-case notes.
Needs Clarification
Missing drawings, unclear material, tight tolerances, or regulated-use flags may pause quote release until answered.
Production Quote
Final quote includes scope, exclusions, line items, lead time, shipping estimate, and payment next step.
Quote Parts with Inspection Needs
Upload CAD and drawings, then note any critical dimensions or reporting requirements.
