What your metallography lab actually checks
Deformation-free, repeatable surfaces
Adjustable force, speed and direction plus 200 saved methods mean the final surface is set by a recipe, not by feel — so porosity counts and grain analysis on AM cross-sections repeat operator to operator, run to run.
An applications engineer on the line
Method setup, consumable selection and troubleshooting from engineers who run sample prep and materials characterization in-house. Sub-4h reply, NDA standard.
