Objective: This work shows surface texture development using several different geometries produced by additive manufacturing. Methodology: The substrates with different surface textures are designed by computer aided programs (CAD). Manufacture of the different surfaces is performed in a layer by layer basis, in a single process using the laser stereolithography technique (SLA), directly from CAD files. Results: substrates surfaces were evaluated by optical tests in order to measure the topography of such surfaces, to validate the surface finishing and to control manufacturing methods by using the strategy of measurement in different profiles. Conclusion: In this study we demonstrated that the printed surface textures showed a reduction in the values of length, volume and mass measurements when compared to the ones defined in the design.
