Multiple identity account 2 Posted November 7, 2013 Share Posted November 7, 2013 As the title say... can someone explain what FUD is and how to get rid of it?Cheers! Link to post Share on other sites More sharing options...
cromptonnut Posted November 7, 2013 Share Posted November 7, 2013 I thought "FUD" was frosted ultra detail, one of the material options available in 3D printing? The only other two explanations I can find for FUD online are "Fear, Uncertainty and Doubt", a marketing tactic, and a brand of hotdogs. Link to post Share on other sites More sharing options...
Bluebell Model Railway Posted November 7, 2013 Share Posted November 7, 2013 3D Printing our Frosted Ultra Detail which is a UV cured acrylic resin. - ShapewaysBelieve it's supported in wax when printed so needs future cleaning once you receive it.Little video to from Shapeways on you tube: Link to post Share on other sites More sharing options...
Penrhos1920 Posted November 7, 2013 Share Posted November 7, 2013 I've heard that models made in FUD are not UV stable and will not last the many years that we might hope. I'd like to establish whether this is or is not true? Link to post Share on other sites More sharing options...
Arun Sharma Posted November 7, 2013 Share Posted November 7, 2013 Hi Penrhos 1920 - I've had various parts from S. in FUD over the last three years - in my opinion, they do become brittle with age and friable. I don't know whether giving them a coat of grey primer makes a difference but since I really only use 3D printed parts as a master for resin/LW/WM casting, the life expectancy of the master hasn't been of great concern.

Multiple identity account 2 Posted November 8, 2013 Author Share Posted November 8, 2013 So can FUD be removed with a slight brush with sandpaper or a good washing up with soap and an old brush? I need a smooth surface for my models. Any advice? Link to post Share on other sites More sharing options...
Talltim Posted November 8, 2013 Share Posted November 8, 2013 FUD is the material the rapid prototyped model is made of (if that's the material you choose) Link to post Share on other sites More sharing options...
corax67 Posted November 8, 2013 Share Posted November 8, 2013 Please excuse my ignorance but if FUD is potentially UV unstable then wouldn't painting it retard any degradation? Link to post Share on other sites More sharing options...

I'd like to establish whether this is or is not true? It also shrinks, slowly over 3-6 months, by about 1-2%. Link to post Share on other sites More sharing options...
SpoorObjecten Posted November 8, 2013 Share Posted November 8, 2013 just measured my own train which was printed mid 2011. Model is still 16.8cm long. Could it be that shrinkage depends on the shape? As for UV stable, some test prints from 2010 are still ok, besides them turning a bit yellowish (this is caused due to the post process we used to have which included corn oil) But I don't know about the material surviving for more than 5years, sorry.

billbedford Posted November 9, 2013 Share Posted November 9, 2013 just measured my own train which was printed mid 2011. Model is still 16.8cm long. Could it be that shrinkage depends on the shape? I made some wheel centres which nicely fitted the axles when new. Six months later they wouldn't fit on the axles. A chat to one of the 3D Systems engineers resulted in him indicating that this was to be expected. The shrinkage is even mentioned on the Shapeways material page.
