Inspection and quality standards

Delivering high-quality parts to our customers is incredibly important to us. As a result, all new partners are required to ship directly to our facility so we can thoroughly inspect all work. Once you show us that you can ship quality work, you may become eligible for our Direct Shipping program, allowing you to ship directly to customers. More on that later.

To aid you in this endeavor, we have prepared a Crash Course on our Quality Clauses. Watch the course and follow along with our downloadable Quality Clauses PDF guide.

To read more about Xometry’s inspection & quality standards, check out this article here in our help center.

Inspection documentation requirements

For all inspections, Xometry requires the use of calibrated tools. Check out this article for more information on inspection documentation requirements.

Standard inspection of a part with a provided print

When a print is provided with the parts, it must be ballooned (by hand is acceptable) to correlate with the inspection report. Regardless of order quantity, 100% of all dimensions, attributes, dimensional locations, and print notes must be documented for the required sample size (See Statistical Sampling Table Below).

If not already on the print, the following needs to be checked and entered into the inspection report (Failure to provide the required information or products resulting in Xometry RMAs - Customer Returns may result in VQC Inspections being instituted):

  • Certificate of Conformance
  • correct material to drawing spec 
  • material test reports if required
  • plating and certification
  • surface roughness (125 or better unless noted)
  • all inserts installed and done correctly,
  • all parts deburred (as per print requirement)
  • all parts clean and threaded holes do not have chips packed in the bottom

Standard inspection of a part with or without a provided print

When a part does not have a print provided, we expect our partners to inspect the part to the CAD file and document these specifications to verify correct set up and programming.

Formal inspection

For a Formal Inspection, Xometry requires the use of calibrated tools where 100% of all dimensions, attributes, dimensional locations, and print notes will be documented per our Statistical Sampling Plan based on ASQC Z1.4 2008 Level II (see below) to an Acceptance Quality Level (AQL) of 2.5% with zero rejects. To facilitate the inspection process, Xometry requires the customer to supply a dimensional print at the time the order is placed.

Inspections performed for a Formal Inspection shall be documented using the Partner Inspection Form QA2F03. Xometry QC will bubble the customers drawing and provide a pre-populated QA2F03 form. The Formal Inspection Form documents the Tool Type, including measurement capability (Ex: .0000-1.00" Diameter Micrometer) used during the inspection. In certain circumstances, XOM may also require the unique Tool ID # for specific customers. Absence of any required information may be considered a non-conformance. On jobs that require this type of inspection, this form will be emailed to the Partner from the Xometry Quality / Inspection Department. Add [email protected] to your email's whitelist so you never miss this important document.

Once the inspection documentation is completed, all forms should be uploaded to the Partner Portal as well as included in the box at the time of shipment.

CMM inspection

A CMM Inspection with Dimensional Report is similar to a Formal Inspection where 100% of all dimensions, attributes, dimensional locations, and print notes will be documented per our Statistical Sampling Plan based on ASQC Z1.4 2008 Level II (see below) to an Acceptance Quality Level (AQL) of 2.5% with zero rejects will inspect using a Coordinate Measurement Machine (CMM). Once the inspection documentation is completed, all forms should be uploaded to the Partner Portal as well as included in the box at the time of shipment.

First Article Inspection Report (per AS9102)

A First Article Inspection Report (FAIR) follows the requirements specified in SAE Aerospace Standard (AS 9102) documentation. The purpose of the First Article Inspection is to provide objective evidence that all engineering design and specification requirements are properly understood, accounted for, verified, and documented. If completing a FAIR, you must maintain a quality record for customer review of accountability and planning, for performing periodic surveillance and audits to verify conformance, for evaluating root cause and corrective action for any non-conformances, and for problem investigations. Random sampling is based on ANSI/ASQ Z1.4 Level II to an Acceptance Quality Level (AQL) of 2.5%. A customer-specified dimensional print is required for a First Article Inspection.

FAIR will be documented using the AS9102 Inspection Report QA2F05. Xometry QC will bubble the customers drawing and provide a pre-populated QA2F05 form. This inspection form documents the Tool Type, including measurement capability (Ex: .0000-1.00" Diameter Micrometer) used during the inspection. In certain circumstances, XOM may also require the unique Tool ID # for specific customers. On jobs that require this type of inspection, this form will be emailed to the Partner from the Xometry Quality / Inspection Department.

    Has the inspection report changed? If so, please refer me to the new doc. Thanks

    @leatherneckpre I love this question. We are actually hosting an Inspection and Quality AMA "Ask Me Anything" event on Thursday, May 13th at 3p with some of Xometry's senior leadership. Kim and Mark will be the best people to answer this question, so I'm going to move your question over to that discussion and make sure it's one of the first questions answered.

    Am I assuming correctly that jobs with the standard inspection are now a formal inspections, just without the VQC? If not, could you please clarify?

    @simply_machining For standard inspections, you will need to include an inspection report, though there is some flexibility in that requirement, which I'll expand on below. For Standard Inspection without VQC, the inspection report can be in any format. If a print is provided, inspection results may be applied directly to the print in red ink for any dimensional characteristics. You can record your inspection results on your standard inspection report format unless otherwise stated.

    If I didn't fully answer your question, I recommend you join our Inspection and Quality AMA today, May 13th at 3pm. We'll be happy to expand on this topic over there!

    Check out our Inspection and Quality AMA that's going on NOW! This event will be live on May 13th from 3 - 4 pm ET. If you can't make it at that time and you have any other questions, throw them in there and we will make sure to answer them for you.

    Love this topic.

    I need to keep up with IT.

    Team... When inspected with a CMM- FARO ARMS, Machining all parts on a CNC what are your thoughts on allowing a lessor Quality Sample inspections count and less “documentation”.

    We are fulfilling a higher count to find out if ran on a CNC and Insp with a FARO/CMM, anyone doing so should not be Inspecting to many parts.

    Or let's just say Less DOCUMENTING.


    Understand?


    Thank team Carlos

    Hi Carlos (@1234567890ABCD___),

    Thank you for your great question. I fully understand your thought, however, we are bound to perform sample inspections and provide specific documentation to satisfy flown-down instructions in accordance with our Customer Purchase Order requirements. It is also necessary to utilize a sampling plan that is in the Xometry Partner Guide to satisfy the AS9100 requirements.

    Regards,

    Mark

    @MKearney - @RogerStull_UET_CGO1 had a great question regarding CMM inspections. How should a Partner know how many points should be checked with a CMM for inspection? Will this be specified in the Part drawing or job details?
