The definition depends on what the file enables
Article 4 of Directive (EU) 2024/2853 defines a digital manufacturing file by its relationship to production. It is a digital version or template of a movable containing the functional information needed to produce a tangible item through automated control of machinery or tools. The definition focuses on function rather than a particular filename extension, software package or production technology.
The file is expressly included in the Directive's product definition. This is a distinct route within the scope of products, alongside movable goods, software, electricity and raw materials. The Directive's recitals explain that digital files generally are not products merely because they are digital. The special treatment of manufacturing files should therefore not be described as bringing every downloadable document within product liability.
Examples include automated fabrication instructions
A file directing a 3D printer to produce a physical object can fall within the definition. Automated machining provides another context: functional information can enable tools such as drills, lathes or mills to create an item. The important question is whether the file contains the functional information required for automated production, rather than whether its supplier markets it as a design asset.
A static illustration used as inspiration by a craftsperson has a different relationship to production. A human-readable drawing may require further design work or conversion before it can control machinery. Avoid deciding classification from a screenshot of the file alone. Preserve the actual file and evidence of how it was intended to interact with the machine, including necessary conversion steps and technical documentation.
File identity is a central evidential issue
Keep the original supplied version, revision identifier and supply records. Where appropriate, a cryptographic hash can help show that an archived copy has not changed, although it does not establish who authored it or whether it was safe. Record the software used to open, convert or prepare it. An exported manufacturing file may differ materially from the editable design source.
Trace any modifications between supply and production. Rescaling, changing wall thickness, adjusting orientation or generating tool paths can affect the resulting object. The version used for the actual production run matters more than the latest file stored in a shared folder. Preserve conversion logs and machine input where available so an investigator can distinguish supplied instructions from changes introduced by another participant.
The file and the manufactured object are distinct
The tangible object produced from the file can itself be a product. If that object is then fitted into another item, the investigation may involve the file, the manufactured part and the assembled product. The discussion of products integrated into other products explains why these identities should remain visible. One supplier's file and another supplier's fabrication work should not be collapsed into a single unexplained label.
An alleged geometry error in the file is different from a production defect caused by an unsuitable material or miscalibrated machine. Both might produce superficially similar breakage. Describe the alleged mechanism before assigning responsibility. A useful technical investigation tests whether the same file, interpreted as supplied and used under relevant conditions, would create the unsafe characteristic alleged in the finished object.
Commercial context and timing still need examination
Article 4's market-supply definitions refer to commercial activity, whether the supply is paid for or free. A file provided without charge can therefore require examination in its commercial context. Equally, the fact that a file is publicly accessible does not establish every condition for liability. Identify the supplier, the terms and circumstances of supply and the relevant market or first-use event.
The corrected Article 2(1) concerns products placed on the market or put into service after 8 December 2026. Record when the file was supplied and when the physical item was produced and supplied rather than assuming those dates are identical. Applying the transitional rules to a particular chain needs examination of the applicable national law. The accident date alone cannot settle the framework.
Being a product is not a finding of liability
Article 7's safety assessment and Article 10's requirements concerning defectiveness, damage and causation remain relevant. A dimensional difference is not automatically an unsafe defect, and a failed build is not automatically compensable damage. Consider the intended use, instructions, relevant safety requirements and the particular risk alleged. A file offered for a decorative model raises different circumstances from one supplied for a safety-critical replacement part.
Preserve evidence of the physical result as well as the digital instructions. Photographs, measurements, fracture analysis and production settings may help connect the alleged file characteristic to the harm. Keep commercial complaints about usability or print quality distinct from allegations of injury or other covered damage. Product classification establishes why the file belongs in the inquiry; the evidence must establish the remaining elements.
Records that help the review
Use the following as a practical starting point. Select and preserve records appropriate to the product, incident and applicable procedure.
- Original manufacturing file with hash and revision
- Machine settings, conversion and build records
- Commercial supply and modification history
Not every digital document is a digital manufacturing file, and an incorrect file does not establish every element of liability.
