Method for Producing or Modifying Silicon Carbide-Containing Articles

A method for making an article comprising silicon carbide, the method comprising:

• producing an article comprising silicon carbide via additive manufacturing;
• and
• heating via at least one laser beam in a site-selective and locally limited manner a surface of the article so as to cause at least one of ablation and chemical modification of the surface.

An apparatus for making an article comprising silicon carbide, the apparatus comprising:

• an additive manufacturing device for producing an article comprising silicon carbide from precursor materials, the precursor materials comprising at least a carbon source and at least a silicon source;
• and
• at least one laser for generating a laser beam, wherein the laser is configured such that the laser beam heats at least a surface of the article.
