GB/T 42156-2023 in English

1. Standard Overview

GB/T 42156—2023 "General Technical Specification for Foundry Sand Mold 3D Printing Equipment" is my country's first national standard for foundry sand mold 3D printing equipment, which aims to unify industry technical requirements and improve product quality and safety. This standard applies to the design, manufacture and acceptance of digital casting equipment that uses binder jetting to manufacture sand molds (cores).

2. Background of Standard Formulation

With the digital transformation of the foundry industry, 3D printing technology is increasingly used in sand mold manufacturing. However, the lack of unified technical standards in the industry has led to uneven product quality. The introduction of this standard fills this gap and provides a scientific basis for the design, production and testing of equipment.
