#Who needs this comparison and how to read it

For an aerospace part that needs machining, sheet metal fabrication, or finishing across multiple suppliers, establish who owns each handoff before placing an order. Ask who selects the manufacturers, resolves production issues, coordinates inspection and documentation, and manages delivery.

Managed sourcing partners select suppliers and coordinate work across processes. Procurement platforms help you find manufacturers and manage orders, though the level of hands-on support varies. Direct manufacturers or factory operators make parts using their own production capacity. Direct shops give you a close relationship with the people making your parts, but you may need to manage work outside the shop’s capabilities.

#Comparison table

Use the table to compare service models, then check the quoted scope for the specific part. Support and inspection records can vary by order.

For each quote, check the price, production site, process scope, and responsibility for inspection records, supplier handoffs, and delivery.

#Vendra

Best for: Aerospace, defense and space teams seeking one partner to source complex parts from qualified U.S. manufacturers and manage production, supplier handoffs, inspection, documentation and delivery, from prototype through production.

How it works: We review your CAD files, drawings, and requirements to identify the processes, materials, tolerances, and quality records the job needs. Our engineers review the RFQ before we match the work with qualified U.S. manufacturers. You can compare quotes and speak directly with the machinists making your parts.

When a quoted part needs machining, heat treatment, and coating from different suppliers, we coordinate those handoffs. We track production and arrange the required inspection and documentation before delivery. You can follow the order and communicate with the manufacturer in one platform.

Key strengths: We manage work across suppliers while giving you direct access to the people making your parts. We hold AS9100D certification and are ITAR registered. If your order requires an AS9100D-certified manufacturer, tell us in the RFQ so we can identify a shop whose certificate covers the assigned site and work. Our certification remains separate from the assigned shop’s certification.

Considerations: Include any approved-supplier requirements, special processes and inspection documentation in your RFQ. Our engineers use these requirements to assess which U.S. manufacturers can make your part.

#Protolabs

Best for: Protolabs suits buyers who want quick-turn options alongside a dedicated production account manager and applications engineering support for complex metal parts.

How it works: Protolabs makes parts in its own factories and sources work through Protolabs Network partners. Its metal contract manufacturing program brings those routes together for projects that may involve machining, sheet metal, additive manufacturing, finishing, and post-processing. A production account manager oversees the program, while applications engineers advise on CAD and cost and operations specialists coordinate logistics.

Key strengths: Protolabs can manage complex bills of materials and coordinate work across its factories and network partners. Its program offers on-site quality control and lists inspection and documentation options for production orders.

Considerations: Ask which factory or network partner will make each part, who will manage process handoffs, and which inspection records your quote includes. For U.S.-only production, confirm the assigned sites and the applicable certification holder and scope. If direct communication with the machinist matters, ask Protolabs whether it is available for your order. We offer direct access to the assigned manufacturer.

#Xometry

Best for: Xometry suits buyers who need a wide range of manufacturing processes and sourcing regions, with engineering and account support available for production work.

How it works: Xometry offers instant quotes for eligible parts and assisted quotes for more involved projects. Its aerospace and defense network includes vetted domestic partners for CNC machining, additive manufacturing, sheet metal, tube fabrication, and assembly.

Key strengths: For production orders, Xometry matches work with vetted suppliers, while its engineering, project-management, and quality staff manage quality, delivery, and supply-chain work. Its aerospace offering includes material and process lot traceability, dimensional inspection, and first article inspection options.

Considerations: Support depends on the order workflow. Before placing a complex aerospace order, confirm whether Xometry will manage handoffs between suppliers, which shop and site will make the parts, and what inspection records you will receive. If the job requires U.S. production or controlled-data handling, confirm the sourcing location and who will receive the files for that specific order.

#Fictiv

Best for: Fictiv suits buyers who need domestic and global manufacturing options, multiple processes, and hands-on program management for non-ITAR work.

How it works: Fictiv sources work through a manufacturing network and offers technical program management for multi-process orders. Buyers should confirm which CNC machining, sheet metal, finishing, and assembly steps Fictiv will coordinate for their part.

Key strengths: Fictiv provides supplier quality management, traceability, and order visibility alongside technical program management.

Considerations: Fictiv’s export-control guidance says its platform does not support ITAR-controlled parts, technical data, or services. Buyers must not upload ITAR-controlled files. Some EAR-controlled work may require off-platform intake and review, so confirm the classification and submission route before sharing files. For a U.S.-production requirement, confirm where Fictiv will make the part rather than assuming every network supplier operates domestically. Check which engineering support and inspection records your quote includes.

#Jiga

Best for: Jiga fits buyers who want to know which supplier will make their parts and communicate with that supplier directly, while a managed platform handles quoting and order tracking.

How it works: Jiga matches custom parts with manufacturers and describes human-reviewed quotes, supplier communication, and inspection reporting. Ask which CNC machining, sheet metal fabrication, and sourcing-location options are available for your order.

Key strengths: Direct supplier communication lets you raise drawing questions with the manufacturer. Jiga also supports revision tracking and inspection reporting within its managed order workflow.

Considerations: Our sourcing focuses on U.S. manufacturers and starts with engineer-reviewed part analysis. Jiga offers a choice of domestic or global sourcing. For a complex aerospace order, ask Jiga to identify the assigned shop and production location, explain who coordinates finishing and other supplier handoffs, and specify who manages inspection documents and production issues. Confirm how Jiga will record revisions and share inspection information for the order, and identify who will receive controlled technical data before sending files.

#Hadrian

Best for: Hadrian fits buyers who want dedicated U.S. factory capacity for precision components, rather than a partner that sources work across multiple independent manufacturers.

How it works: Hadrian builds and operates American factories and uses Opus software in its manufacturing operations. Confirm whether Hadrian’s quoted offering is a part order, dedicated manufacturing or inspection cell, or factory program, and where the work will take place.

Key strengths: Hadrian’s direct production model gives buyers a path to dedicated capacity. Its cell and factory offerings suit programs that need more than individual part orders.

Considerations: Confirm which facility will make your parts and what the quote covers for finishing, inspection records, and any work outside that facility. If your part needs work outside Hadrian’s quoted facility or process scope, ask who selects and coordinates the other suppliers.

#Direct shops

Best for: A direct machine shop or fabricator fits when you already have a qualified supplier and can manage any work outside its scope. For a part made mainly through one process, a direct relationship gives you access to the people making it and lets you discuss design changes and costs with them.

How it works: You select and qualify the shop, then send it the drawings and production requirements. The shop makes the part and may arrange subcontracted finishing or other steps if those services are included in its quote. If machining, sheet metal, and finishing require separate suppliers, you coordinate the handoffs unless one shop explicitly takes that responsibility.

Key strengths: A shop that specializes in your process can give detailed feedback on tooling, tolerances, and inspection methods. Working directly with that shop also gives you visibility into its pricing and production decisions.

Considerations: Confirm which subcontractors the shop uses, who checks their work, and who provides material certificates, special-process certificates, and inspection records. The shop can resolve issues in work it controls. You must resolve gaps between suppliers and manage delivery across separate orders unless a shop agrees to take responsibility for that work.

#Verifying AS9100 and ITAR before you commit

Check the specific manufacturing site and data path before you approve an aerospace supplier. A managed partner’s credentials do not automatically cover the shop making your part.

• Verify the AS9100D certificate. Confirm the certificate holder, manufacturing site, scope, and current validity. When your program requires an AS9100D-certified manufacturer, check that the assigned manufacturing site and its work fall within the certificate’s scope.
• Confirm where each process happens. Ask where the part will be machined, finished, and inspected. If a subcontractor handles a step, check whether your quality requirements apply to that site as well.
• Map access to controlled technical data. Identify every partner, shop, subcontractor, and individual who will receive drawings or other controlled files. Confirm the applicable authorization for each transfer before sharing them.

Our AS9100D certification and ITAR registration are separate from the assigned manufacturer’s qualifications. Ask us to identify the manufacturing site and the records you need to check its fit for your program.

#RFQ checklist for complex aerospace parts

Send each provider the same files and requirements so you can compare quotes against the same part, quality requirements, and delivery date.

• Part definition: Include CAD files and revision-controlled drawings. Identify the current revision and any critical tolerances.
• Production requirements: Specify the material grade, quantities for each release, and required processes, including any machining, sheet metal work, finishing, or approved special processes.
• Schedule: Give the required delivery date and note whether you need prototype quantities before a production run.
• Quality documentation: List required material certificates, special-process certificates, and lot or serial traceability. If required, specify AS9102 first article inspection and the first article inspection report.

We can review your RFQ and coordinate the quoted work with qualified U.S. manufacturers.

#FAQs

What is the difference between a managed sourcing partner and a procurement platform? A managed sourcing partner takes responsibility for the supplier selection and production coordination defined in the order. A procurement platform provides purchasing tools and may also offer hands-on production support. Ask either provider who manages handoffs, inspection records, and production issues for your specific job.

Does ITAR registration mean a provider can accept my controlled files? No. Vendra is ITAR registered, but registration alone does not authorize every transfer. Before sharing files, confirm who will receive the data, where they will access it, and which authorization applies to your program. Fictiv’s published guidance says not to upload ITAR-controlled files to its platform.

When is a direct shop a better fit? Choose a qualified direct shop when you have an established relationship and the shop can handle the required processes, inspection, and documentation. If several suppliers must share the work, ask who will manage each handoff. Vendra can take on that coordination when you do not want to manage it yourself.

What does AS9102 first article inspection require? AS9102 defines requirements for planning, performing, and documenting a first article inspection. The first article inspection report records verification of the applicable design characteristics and supporting material and special-process requirements. Tell Vendra when your order requires an AS9102 report so we can confirm the inspection plan and documentation with the assigned manufacturer.
