If you have two very similar Models (like shipping address and billing address) and you need to make a copy of one to another, you can use replicate() method and change some properties after that.
Example from the official docs:
$shipping = Address::create([    'type' => 'shipping',    'line_1' => '123 Example Street',    'city' => 'Victorville',    'state' => 'CA',    'postcode' => '90001',]); $billing = $shipping->replicate()->fill([    'type' => 'billing']); $billing->save();
