   Technical Review Guideline of Medical Device Registration for Customized
   Additive Manufacturing
   (Feedback Draft)
   Preface
   The guideline is intended to encourage the innovation and development of medical device, provide technical guidance for the registration of medical device for customized additive
   manufacturing (or “3D printing” for short), and offer technical reference for the food and drug
   supervision and administration departments on registration materials review. This guideline is the general requirements of medical device product registration materials
   for customized additive manufacturing, and the applicant shall specify the registration materials
   according to the specific characteristics of the product and determine whether the specific
   content is applicable or not according to the features of specific product. This guideline is the guiding document for the applicant and the reviewer, but excludes the
   administrative matters involved in the registration and approval. It is not mandatory regulation.
   If there are other methods that can meet the relevant regulatory requirements, it may also be
   adopted, but detailed research data and verification data are required. This guideline shall be
   used in accordance with relevant regulations and standards. This guideline is formulated under the current laws, regulations, standard systems and
   knowledge levels. With the constant improvement of laws, regulations and standards as well as
   the continuous development of science and technology, the related content of the guideline
   will also be adjusted timely. I. Application scope
   This guiding principle applies to the following situations:
   Put forward by clinicians, customized design is applicable to the special disease condition
   and/or special anatomical structure, which is a medical device through the additive
   manufacturing technology, in order to satisfy the clinical need difficult to be solved by existing
   standardized medical device or better meet special clinical requirements. This guiding principle covers skeletal, joint and dental passive implantable medical devices. This guiding principle is unable to cover all requirements of medical devices with special design
   such as 3D bio-printing of biological active substances with drug ingredients, cells and tissues, but the applicable specific requirements can be taken as a reference. The passive nonimplantable medical device of customized additive manufacturing can refer to the applicable
   specific requirements. II. Classification principle of registration unit
   The products with different design methods of the main components of registered
   product, additive manufacturing methods (material and process), application scopes and key
   performance indicators shall be divided into different registration units. Othercircumstances
   may refer to the relevant requirements of the Classification Guidelines of Medical Device
   Registration Units and the guiding principles of product technical review. III. Registration Application Materialsrequirements
   (i) Product name
   According to the Classification Rules of Medical Device, General Naming Rules of Medical
   Device and other relevant documents as well as the design characteristics and applicable scope
   of registered product, its management category, classification code and normative naming
   (product name and component name) are determined to discuss its determination basis. (ii) Product description
   To describe the chemical compositions and proportions of raw materials for each
   component of the product. To describe the product structure and its characteristics, discuss the rationality of
   structure and form design, and provide illustrations. To describe the connection relation between product interface structure and human
   tissues.(iii) Model specifications
   To describe the relevant clinical dimension parameters, structural features, size range
   (maximum and minimum) and tolerance, and specify the classification principle of model
   specifications. (iv) Intended use and contraindication
   To describe the specific use parts of the product, applicable population, use situation
