General requirements

Date of introduction - 2017-12-01

  • Application area

This International Standard establishes the basic principles of additive manufacturing processes. This International Standard provides an overview of existing processes and is not intended to be exhaustive due to the development of new technologies. This International Standard explains what equipment is used in different process categories.

  • Normative references

This standard uses normative references to the following standards:

GOST R 57558 Additive technological processes. Basic principles. Part 1. Terms and definitions

GOST R 57589 Additive technological processes. Basic principles. Part 2. Materials for additive manufacturing processes.

  • Terms and definitions

In this standard, the terms according to GOST R 57558 are used.

  • General provisions

This standard provides a list of equipment used for various categories of existing additive processes.

  • Existing process categories
    • Bath photopolymerization: a process in which a pre-deposited photopolymer is selectively irradiated with light. Under its influence, adjacent polymer chains are attached to each other.
    • Material spray application: An additive manufacturing process in which the fabrication of an object is accomplished by applying drops of building material.
    • Binder Spray: An additive manufacturing process in which a liquid binder is selectively applied to the bonded powder materials.
    • Substrate synthesis: an additive manufacturing process in which the surface of a pre-applied layer of powder material is selectively completely or partially melted
      thermal energy.
    • Material extrusion: An additive manufacturing process in which material is selectively fed through a nozzle or orifice.

Official edition
