<p>I would like to print parts (e.g. jewellery) for use which I don't want to look or feel like a plastic, but metal-like, so briefly people won't see much difference.</p>

<p>Are there any specific type of home-printers that can achieve that? Or it's rather kind of filament that you should use?</p>
