How do you make and print 3D photos without using 3d glasses?

You don't need glasses to make or print a 3D image.

You will need a 3D camera, though.

In order to view the image you will need glasses which ensure that the two slightly different perspectives reach the correct eye. This is what gives the impression of being 3D.

Bear in mind that the only kind of 3D image possible on paper is an anaglyph (red/blue tinted). The brain interprets the image as 3D but there will be no colour, it will appear as "black and white".
