Many nylon and polyamide parts can be laser marked, but the result\n          depends on the exact PA grade, color, moisture condition, fillers, additives,\n          molded surface and required mark effect.

The main risks are roughness, uneven appearance and exposed fibers,\n          so the actual GF grade and surface should be tested.\n        <\/p>\n      <\/details>\n\n      <details>\n        <summary>Which laser should be tested first for nylon?<\/summary>\n        <p>\n          There is no universal best laser for every PA compound. Fiber\/MOPA and UV are\n          common early comparison routes for many identification and code-marking tasks,\n          while CO2 may be evaluated for selected removal or texturing work.
