Dynamic redirect to different controllers

My application has some entities in db, and each one contains data about controller name.

When route is called it calls MainController and followed method which then redirects to different controllers.

protected function dispatchPDF(Request $request){
   $ent = Entity::find($request->id);
   $variable_name = $ent->controller_name; 
   return resolve("\App\Http\Controllers".$variable_name)->printPDF();
}

Is there any better way of doing this?
