I've been sitting on those pictures for too long, but didn't have the time to put words to paper.
I'm calling this WIP shots, as it's too barebones for a proper tutorial but hopefully you'll get a clear idea of my process and what to expect from those shapeways models.
You can see more pictures of the finished model here : http://www.rule37.net/2014/09/x-wing-showcase-anakin-jedi-interceptor.html
And my analysis of the raw material here : http://www.rule37.net/2014/09/3d-printing-future-of-miniature-gaming.html
First I started by drilling a hole 6mm wide underneath to accomodate the ring magnet I used :
As you can see on the next picture the printing process leaves distinct straight lines:
Which I cleaned up like regular mould lines with an X-Acto:
I then airburshed white over the whole model, but you could also hand paint it.
To give me a better sense of the model, I blocked the canopy in black.
The front panels are flat and lack the distinctive armor panels of the ETA 2, so I started to free hand those, first painting the edges.
Then once the shapes were in, I blocked the panels in yellow.
I finished with highlighting and shading the panels, and painted the canopy.
The rear exhaust trails where made with heat thinned transparent rod, painted with white and a transparent blue.
Time to reload,
