Описание (английский):

This document specifies the features of electron beam powder bed fusion of metals (PBF-EB/M) and provides detailed design recommendations. Some of the fundamental principles are also applicable to other additive manufacturing (AM) processes, provided that due consideration is given to process-specific features. This document also provides a state of the art review of design guidelines associated with the use of powder bed fusion (PBF) by bringing together relevant knowledge about this process and by extending the scope of ISO/ASTM 52910.

Overview

ISO/ASTM 52911-3:2023 - Additive manufacturing - Design - Part 3: PBF‑EB of metallic materials - specifies features and detailed design recommendations for electron beam powder bed fusion of metals (PBF‑EB/M). The document consolidates state‑of‑the‑art guidance for designing parts for PBF‑EB, extends the general AM design principles from ISO/ASTM 52910, and highlights process‑specific considerations that influence geometry, material behavior, and post‑processing.

Key phrases: ISO/ASTM 52911-3:2023, PBF‑EB, electron beam powder bed fusion, additive manufacturing design, metallic materials.

Key Topics and Requirements

Process characteristics and constraints

Features common to powder bed fusion (PBF), plus PBF‑EB-specific effects such as heat management and the curl effect.
Tradeoffs in part size, build cost and layout (orientation, nesting, stacking).

Design principles

Guidance on build orientation, part positioning, and support‑structure strategies tailored to PBF‑EB/M.
Recommendations for addressing feature constraints: islands, overhangs, and the stair‑step effect.

Material and structural behavior

Effects of PBF‑EB on anisotropy, grain morphology, porosity, chemical heterogeneity and thermal history.

Manufacturing parameters

Considerations for powder spreading, melt parameters, and build plate interactions that influence part integrity.

Surfaces and post‑processing

Finishing, powder residue removal, support removal, heat treatment and geometric tolerancing guidance.

Design details

Best practices for cavities, gaps, wall thickness, holes/channels and integrated markings.

Examples and case studies

Practical examples (e.g., topology‑optimized brackets, orthopedic cups, implants, lightweight piping) illustrate recommended approaches.

Practical Applications and Who Uses It

This standard is intended for:

Design and production engineers creating metal parts for PBF‑EB.

AM process engineers and manufacturing planners who set build strategies and parameters.

Quality, inspection and post‑processing teams ensuring parts meet tolerances and functional requirements.

R&D and materials specialists studying microstructure, porosity and heat treatment effects.

OEMs in industries exploring advanced metallic AM (e.g., aerospace, medical devices, energy) seeking robust design-for‑AM (DfAM) practices.

ISO/ASTM 52911‑3 helps users exploit PBF‑EB’s design freedoms while avoiding process‑related failures, reducing iteration cycles and improving part performance.
