3Dresyns Quality Policy

3Dresyns is committed to the controlled design, manufacture and supply of made-to-order materials for professional additive manufacturing workflows.

Product quality is managed through defined specifications, lot-level controls, traceability and continuous improvement. Safety, regulatory suitability and compliance depend on the specific product, jurisdiction, intended use and applicable material and process documentation; they are not inferred as universal properties of the portfolio.

3Dresyns Quality Management System (QMS)

3Dresyns operates an internally managed non-ISO-certified Quality Management System designed to support controlled manufacturing, traceability, corrective actions, process monitoring and continuous improvement.

The QMS is structured around practical controls appropriate to a made-to-order materials business, including:

Defined product and manufacturing specifications
Lot-level quality controls
Traceability of production and quality records
Internal review and corrective and preventive actions
Process monitoring and continuous improvement
Protection of intellectual property, industrial trade secrets, know-how and customer confidentiality

This structure allows 3Dresyns to combine controlled quality processes with the flexibility required for material development, customisation and digital manufacturing.

Quality management and Artificial Intelligence

3Dresyns uses multivariate and AI-assisted methods to support material design, process analysis and customer-specific printing-parameter optimisation under human technical supervision.

This is particularly relevant to configurable multifunctional material systems, where multiple formulation and performance variables may need to be evaluated simultaneously.

Depending on the relevant product or configuration system, selectable variables may include:

Multiple colour options
Up to 4 functional additives per resin where applicable
A broad range of functional additive options
Multiple made-to-order material configurations

These systems can use multivariate, multiresponse, predictive, interpolative, extrapolative and corrective computational methods to support proof-of-concept work, feasibility studies and customised multifunctional materials.

Quality management approach

3Dresyns currently operates its quality system without formal ISO QMS certification. The company uses internal quality controls, traceability, process review, corrective and preventive actions, data analysis and continuous improvement to manage the quality of its products and services.

Formal certification status should be distinguished from product-specific specifications, testing, regulatory documentation or application-specific validation. Where a particular standard, test method, certification or regulatory status applies, it is stated within the relevant product or technical documentation.

3Dresyns Quality Control

3Dresyns performs quality controls to verify that production lots conform to the applicable manufacturing specifications for each product reference. The QMS includes monitoring, review and optimisation of relevant processes to support consistent manufacturing quality and traceability.

AI-assisted optimisation of printing settings

3Dresyns uses multivariate and AI-assisted methods not only for material design but also to support the optimisation of customer-specific printing settings.

For applicable made-to-order multifunctional 3D resins, 3Dresyns can provide a curing rate table, providing a kinetic printing fingerprint measured under defined test conditions selected to support comparison with the customer's printer conditions.

Curing rate tables may be generated using 405 nm light at multiple exposure times, including 5, 10, 15, 20, 25, 50, 75 and 100 seconds, with cured layer thickness measured to characterise resin curing behaviour under the specified conditions.

Light power matching (“synchronisation”)

For improved comparability between laboratory calibration and customer printer conditions, 3Dresyns recommends measuring the actual light power of the printer with a suitable UV light meter.

One instrument used by 3Dresyns is the Chitu Systems Digital UV Light Meter, which covers the wavelength range relevant to common 405 nm vat-photopolymerisation printers.

Sharing measured printer light power allows the laboratory curing data and customer printer conditions to be compared through light power matching, supporting more efficient identification of suitable starting printing parameters. See: Fast and accurate IFU for DLP & LCD printers.

Human expertise + Artificial Intelligence

Measured curing kinetics, formulation data and quality-control information can be used within 3Dresyns multivariate computational models to analyse relationships between material variables, printing behaviour and printer conditions.

These tools are used under human technical supervision to support material development, process optimisation, reproducibility and continuous improvement.
