3D resins are raw materials, not finished medical devices

3Dresyns® photopolymer resins are supplied as raw materials intended for use in additive manufacturing workflows. They are not finished medical devices, nor final consumer products.

As raw materials, 3Dresyns resins are designed to be processed, modified and transformed by the user through printing, post-processing and application-specific workflows.

Distinction between raw materials and medical devices

A medical device is defined by:

• its intended medical use

• its final form

• its validated manufacturing process

• its regulatory approval and certification

3D printing resins, by contrast, are intermediate materials that require further processing before becoming a finished part or device.

The transformation of a resin into a medical or dental device depends on:

• the selected resin system and version

• the printer technology and parameters

• post-processing and post-curing conditions

• final geometry, surface finish and intended use

These steps are controlled by the user, not by the resin supplier.

Role of 3Dresyns in the value chain

3Dresyns provides:

• photopolymer resin systems

• reference workflows and Instructions for Use (IFU)

• typical performance data obtained under qualified conditions

3Dresyns does not manufacture, place on the market or certify finished medical devices.

Responsibility for device design, manufacturing validation and regulatory compliance lies with the manufacturer of the final printed device.

Biocompatibility versus medical device approval

Some 3Dresyns resins may exhibit biocompatible behavior when processed under defined conditions.

However:

• biocompatibility of a raw material does not automatically confer medical device approval

• final device biocompatibility depends on the complete manufacturing process

• changes in printing or post-processing conditions may affect biological response

Users must perform their own validation and qualification for the intended medical or dental application.

Regulatory responsibilities of the user

Manufacturers of final medical or dental devices are responsible for:

• selecting appropriate materials

• validating manufacturing processes

• performing risk assessment and biocompatibility testing

• ensuring compliance with applicable regulations and standards

3Dresyns supports these activities by providing technical documentation, but does not assume regulatory responsibility for finished devices.

Importance of following Instructions for Use

Because photopolymer resins are process-dependent, adherence to the applicable Instructions for Use (IFU) is essential.

IFUs define:

• qualified reference workflows

• processing boundaries

• typical performance expectations

Deviations from IFU guidance must be validated by the user.

Avoiding misleading claims

Printed parts produced using 3Dresyns resins must not be marketed or represented as approved medical devices solely on the basis of the resin used.

Claims regarding medical use, safety or compliance must be supported by appropriate validation and regulatory approval at the device level.

Governing principle

3Dresyns resins are raw materials and manufacturing systems, not finished medical devices.
Final device performance, safety and regulatory compliance depend on the complete user-controlled manufacturing process and must be validated by the device manufacturer.
