While no official books discuss traveling between different Material Planes, Mike Mearls (a designer for 5e) has spoken about it in a youtube video by D&D Beyond.
What it boils down to is the construction of a vessel capable of traversing the stuff between "crystal spheres" (regions that house different Material Planes) which is called "phlogisten". There are no rules in 5e for this yet, but you can get some insight by reading the Planescape campaign setting for AD&D 2e
