Font 3d, create font, font style

Create your graphic. 

I used separate type layers for each letter.

Converted the text to shapes (under Type menu) and reformed.

I could have added an inner gradient layer style, but I chose to lock the transparency, and paint on the coloured shading.

Give that layer a 1 pixel mauve/purple stroke.

Copied the layer, and edited the lower of the two increasing the stroke to 16 and changed colour to the light mauve.

Added a second stroke _under_ the 16 pixel stroke. This one was set to 17 pixels, and colour set to a darker mauve.

I don't know what that original font is, but I'd love to add it to my fonts.

Photoshop > Styles Panel. 

Select text layer and apply Clear Double Black Stoke (see screenshot).  

Hope that helps.
