About the Program
AM Machine Operator Certification (AMC-MO, PBF-LB/M) certifications provide third-party, time-limited recognition that an individual has demonstrated competency against established criteria, with ongoing requirements to maintain proficiency.
What is ASTM AMC-MO?
ASTM AMC-MO is a personnel certification qualifying machine operators of laser metal powder bed fusion machines and associated equipment in accordance with ISO/ASTM 52942 and ISO/ASTM52926-2
The Certification is specific to:
- Machine manufacturer and model
- Powder material group A to F as specified in the standard. For example, Material group B: Austenitic, martensitic, and precipitation hardening steels
Why ASTM AMC-MO?
- As AM scales into production of critical components, the need to verify operator competency is increasing
- Provides a standard approach to qualifying metal PBF machine operators
- Supports standards and customer requirements that call for operator qualification
- Demonstrates organizational commitment to quality and safety
How does AMC-MO work?
- Built on ISO/ASTM 52942 and ISO/ASTM 52926-2
- Co-developed with machine manufacturers to ensure accuracy and completeness
- Two-part assessment:
- Online theoretical exam (minimum 80% score)
- Practical on-machine demonstration according to Additive Manufacturing Procedure (AMP) specification
- Assessments conducted at OEM application centers or customer sites

Location for assessment
- OEM Application Centers or Customer Site
Pre-Requisites
- Candidate for certification should have an experience operating machine. She/he should have completed at least six builds prior to applying for certification.
- Certification is valid for two years. To maintain certification for two years the machine operator will need to operate machine on a regular basis (at least once per six months).
- Vision Test: Candidate for certification would need to provide evidence of vision test from a medical practitioner. It should be available for optional audit, but ASTM will not take possession of results. This includes:
- Near vision acuity (need to be tested every two years)
- Color perception (need to be tested every six years)
- Operator qualification is assessed through a two-part examination covering the key topics in the standard.
- Part 1 Theoretical Exam: Online exam conducted by ASTM with a minimum 80% score
- Part 2 Practical Exam: On-machine demonstration of proper setup and operation of PBF-LB machine according to Additive Manufacturing Procedure (AMP) specification.
