if your custom post type uses the built in categories the above should work. If it has it’s own custom taxonomy instead, you should use something like wp_get_object_terms instead

Yes, I use a special taxonomy but not show it. This is called “categorias”.
Are you trying to display a list of assigned categories at the bottom of a post, or?
I need to show the categories to which my post_type “articulos”.
yes but where do you need to show them? On a sidebar to where all those post_type is articulos, or at the bottom of a post listing all of them that the post is assigned to? I will provide the function for you to do that, but both are different.
Ok, replace lines 26 and 27 with…
<?php
echo get_the_term_list( $post->ID, 'categorias', '<p>', ', ', '</p>' );
?>
This will display links for each term with a comma separator.
You can replace the <p> and </p> with whatever wrapper you want to use that wraps the entire list.
If you want an actual list you can do…
<?php
echo get_the_term_list( $post->ID, 'categorias', '<ul id="my_term_list"><li class="categoria">', '</li><li>', '</li></ul>' );
?>
