Inspection Standards

At 3DCareDesign, in conjunction with our manufacturing partners, thorough visual and dimensional inspections are conducted prior to the shipment of orders. Our methodology incorporates the utilization of standardized defect documentation and inspection criteria, ensuring a uniform level of quality control irrespective of the production location or timeframe. In cases involving multiple units of a given line item within an order, our partners and inspection teams adhere to ISO2859 - General Level 2 sampling.

To illustrate, a batch comprising 20 units undergoes inspection through a representative sample of 5 units.

Defects are meticulously cataloged with accompanying visual references, along with an assessment of their severity, which corresponds to AQL (Acceptable Quality Level) classifications for the purpose of inspection.

These defects are classified according to five primary properties:

• Category: Encompassing Surface Finishes, Tolerances & Dimensions, Threads, Materials, Parts Finishing & Cleaning, and Packaging.

• Name: Providing a concise description of the identified defect.

• Level: Signifying the criticality and impact of the defect.

• Poor Image: An illustrative depiction of the defect.

• Good Image: An exemplar showcasing an acceptable part.

Categorization of defects levels

During the inspection process, adherence to the 3DCareDesign defect book serves as a guiding principle. The assessment considers the defect level in alignment with AQL standards, denoted as Cr 0 M 2.5 m 4. A defect is defined as a deviation from the technical specifications outlined by 3DCareDesign and/or the specific requirements of the customer.

• Minor defects typically have a slight impact on the visual appearance of the parts, but generally do not impede their functionality. 

• Major defects, on the other hand, represent more significant discrepancies that can potentially affect the usability of the parts. 

• Critical defects are of utmost concern, as they not only impact usability but also have the potential to result in harmful or hazardous situations if the part is employed in its current state.

In instances where parts do not conform to the customer's specified requirements and/or the technical specifications set forth by 3DCareDesign, the inspection findings are communicated to the customer for their consideration. It is important to note that the customer retains ownership of the part design and its intended usage.
