TCPDF get value from database

I'm trying to get a value from the database. I want to get the name of id '17'. I'm using Laravel 5.4 and Tcpdf

This is my controller code:

public function createpdf($id) {

$scan = Scan::find($id);    
$pdf = new \TCPDF();

$pdf->SetPrintHeader(false);
$pdf->SetPrintFooter(false);
$pdf->AddPage();
$pdf->Text(90, 140, 'Test');

$filename = storage_path() . $scan->name . '.pdf';



$pdf->output($filename, 'F');

return \Response::download($filename);

}

The error i get: Trying to get property of non-object

How do i fix this? A foreach doesn't do the trick..
