A few of the finest 3D printers obtainable proper now use UV resin moderately than filament to provide fashions. These printers have a tendency to provide smaller, extra detailed fashions than the bigger FDM printers and can be utilized to make board sport miniatures and even wonderful jewellery and dentistry. 

These printers use a particular sort of UV resin that is available in a wide range of colours and chemical compositions, every of which might create a unique sort of finish end result.
