Looks great ! Could we know the complete name of the machine ProJet [complete name] ? I think I mentioned this technology in almost every surveys I received from Shapeways, glad to see it became reality !

WOW!!! This looks fantastic! Going to have to put on my design hat and get something going!!!

Awesome, look forward to seeing your designs!

Well. This is great. As one of those "model railroad fans" the White Detail just wasn't fine enough. This may very well be the ticket!

Nice ice cube truck! =)

Haha, that is actually support material trapped inside because the designer left out the holes..

Excellent and exciting!

Expect my first order before midnight. :-)

Will be taking a very serious look at this for my train projects
#6 Bob Davies on 2011-04-21 15:55 (Reply)
How about painting?

The photo in the middle is actually a painted example. Is that along the lines of what you're looking for?
#7.1 nancyliang on 2011-04-26 15:20 (Reply)
FYI, that part was painted with Testors Model Master enamels.

This is great news, I'm really interested. I'll make some prints in a very short future. Please keep this one permanent ! :-)

Nice! What is the layer thickness used by the machine's software when it slices up a model for printing? Models being printed in White, Strong & Flexible get sliced into 0.15mm layers...
#9 GWMT on 2011-04-21 20:24 (Reply)
Can I get back to you on that? I just want to double check!
#9.1 nancyliang on 2011-04-26 16:25 (Reply)
Hey! Build layer is 40 micron for FD, and 30 micron for FUD. I will also add these questions/answers to the design rules. After I finish a nifty little thing I will launch soon. :-)

Just place a 'sample' order. Looking forward to seeing the results
#10 Bob Davies on 2011-04-21 21:11 (Reply)
Looks really nice. Will definitely have to design something for the FUD... and like someone else asked - what about the painting of this material? What was used in the sample shown?

#11 Glenn Slingsby (Homepage) on 2011-04-21 22:09 (Reply)
Let me get back to you on that? It was prepped by one of our community members, so I'm not sure of the exact formula he used. I did get feedback that the surface was smooth and did not require much prep for painting though!
#11.1 nancyliang on 2011-04-26 16:28 (Reply)
Got the answer! The part was painted with Testors Model Master enamels.

The pricing of FUD (!) seems quite high to me. I create 1:87th scale models, and a standard fully equiped railcar costs well beyond $120 in the new material... When I create a model, I'm never 100% sure the assembly will work like expected (you know, on CAD everything is perfect, no gravity, no manufacturing tolerances and no "too big" fingers...). I'm creating a very small shunter scale model to try this new material out, however...

I'm a Model Railroader in 1:48. Currently I'm interested in the parts that I can't make easily in that scale. For example I scratch-built some 6" Gate Valves in 1:48 .. they came out pretty good but I would MUCH rather have them printed if possible. If I was looking at producing a number of railcars then it seems to me that th $60-$120 each is feasible if you use them as masters to cast multiple copies in resin.

These frosted materials allow thinner walls than plain white detail or even wsf, so by doing thinner walls (with a reinforcement grid and other supports in non visible parts) the price should be less scary than it sounds. Different material, different rules. It's a lot easier to reinforce the inner surfaces before assembly and painting, than to smooth the outter ones, after all.

Take a full pannel (20*100mm, USD prices, no VAT, no start up), in WSF (0.7mm thickness) it would be 2.10, current transparent detail (1mm) 5.54, frosted 2.89 (0.5mm) and ultra (0.3mm) 2.63 or (0.5mm, safer and reusable for plain frosted) 4.39. In factors against the cheapest (wsf, 2.10) 1x, 2.64x, 1.37x, 1.25x, 2.09x. If the detail and smoothness is there, the rest is just (re)designing for the new material.

I hear ya, but the Ultra Detail takes a longer time to print. So it's really the machine time that drives up the cost. As with all our material, we will be looking into ways to reduce costs over time.

This is exciting! We'll have to see how my minis come out now... I guess I will hold off on the remaining painting to be done.

I did some digging - the machine specs are here:

WOW!! Layer thickness is 0.04mm/0.0016in for Frosted Detail with a minimum resolution (think of it as the size of one pixel) of 0.08 x 0.08 x x0.04mm. Frosted Ultra Detail layer thickness is 0.032mm/0.0013in with a min. resolution of 0.04 x 0.04 x 0.032mm.

Nancy - how much would parts in Xtreme High Definition (layer thickness 0.016mm) cost? Twice the cost of Frosted Ultra Detail?

@fx2: For most parts of a car Frosted Detail should produce acceptable results. Maybe produce the super-fine detail parts like doors, ends and roof as separate parts in Frosted Ultra Detail that fit into holes in a Frosted Detail carbody. Shrinkage is only 0.002" per inch so a light pass with a file should fix any fit problems.

I agree $60-$120 per 1:87 railcar (before details, trucks and couplers) isn't cheap, but the alternative is dozens of hours spent building from scratch. The way things are progressing that $120 car will probably be $40 in three years with even finer detail.

Regarding painting, the material is an acrylic so enamel and acrylic paints should work fine.

Thanks Shapeways!

I think Xtra Detail would require another machine. Currently we are testing the waters with these two material, maybe in the future we can look into even more detail? For now, I want to be kind to Stony's carpal tunnel.

Very interesting! I am an HOn30 modeller and had already designed some parts to convert and N-scale Shay locomotive to an HOn30 Shay. I had designed them for a different service provider, but with this new material I should be able to have them printed at Shapeways. Same applies to a part for a wholestick sugar cane truck. I have already ordered them and am curious to see the result. Will post some pics of them on the forum, once they have arrived.
#15 Spoors on 2011-04-23 15:19 (Reply)
Yep. Same here in that I have had some On30 stuff printed elsewhere .. simply because of the resolution, some of which I had planned to reproduce in resin because of costs. With this new material from Shapeways I went ahead and just ordered the quantity I needed. Like you, I am curious (and hopeful) that they meet my needs
