The invention relates to a method comprising the steps of: Abrasion, preferably but non-limited by means of sandblasting which produces mechanical roughing on the surface of the glass substrate, optionally applying a primer on the roughed surface, and applying an ink on this primer by means of screen printing which may be digital inkjet screen printing, drying the injected ink deposited by means of digital screen printing, and performing a tempering process. A glass substrate with an embossed surface finish is achieved which simulates the aesthetic and surface texture of different construction materials, such as stone, wood, granite, marble or porcelain, among others.

Orthopedic implants produced by additive manufacture, followed by refinement of exterior and interior surfaces trough mechanical erosion, chemical erosion, or a combination of mechanical and chemical erosion. Surface refinement removes debris, and also produces bone-growth enhancing micro-scale and nano-scale structures.
