About silk filament
Silk filament is usually PLA blended with additives that give prints a glossy, almost metallic sheen. The shine hides layer lines, which is why it is popular for vases, figures and gifts.
The finish varies between brands and even between colours, so the reviews and photos on each product page are worth a look. Dual-colour and rainbow silks change colour across the print or along the spool.

Is silk filament harder to print than normal PLA?
A little. Silk filament tends to string more and its layers bond less strongly than plain PLA, so it suits decorative prints better than parts that take a load. Printing a little slower usually brings out more shine.
