Is there a reason you didn't use non-stick spray on the sample holder prior to pouring the resin? Also, for the epoxy non conducting for the SEM - can you not sputter gold to reduce the charging?
then the specimen will be useless. Grinding and polishing ensures a smooth and deformatin-free specimen, free of scratches, etc. If you do not grind and polish you will not get accurate hardness readings (if doing micro hardness testing) and false microstructures if trying to interpret microstructures.
Thank you so much man
amazing info. hello from slm 3d printing jobshop✌🏻

No reason, in fact I had some trouble getting them out. I should have, ha! And yes, sputtering is the best way to reduce charging. I used carbon.
what will happen if the grinding and polishing steps are not followed or ignored?
