That's good, guess I still beat them then. I actually prefer the multiple units, on aesthetics! -

bluemattersoda replied to bluemattersoda's topic in Swiss Railways
Hi everyone, I've got photos of the painted model over at 3D printing threads http://www.rmweb.co.uk/community/index.php?/topic/113998-sbb-twindexx-intercity-n-scale-spur-n-echelle-n/&do=findComment&comment=2904722 Probably be selling these on Shapeways this week! Thanks all, Alan -
Thanks, and sorry for the loooong delay replying! I've sort of given up on the drive train idea...unfortunately at N scale the gears and 3D printing them is too finnicky and fragile. I've gone back on relying on Tomytec chassis. HO scale on the other hand my be more suited! Hi all, it definitely has been a long time since I updated this thread. The first RABE 502 started passenger service spurred me to finish painting the test prints, so here they are! Soon to be available on Shapeways. I've also started an Instagram account @platformtrains since the last I updated - feel free to check it out! Thanks for viewing, Alan

Hey sorry for the looooong delay to responding - completely slipped my mind! Z gauge is definitely possible though unfortunately don't have any plans at the moment. However I am planning a HO version in full color sandstone, depending on the success of the test prints Cheers! -

Hi, they aren't in passenger service yet, still in testing around Switzerland. i think they are slated for service this year -

Hi all, long time no post. Here's the updated print. I've decided to use decals for the livery rather than paint. I'm still making the decals at the moment, and the white undercoat isn't as good as I hoped. There are more photos in the 3D printing forum: http://www.rmweb.co.uk/community/index.php?/topic/113998-sbb-twindexx-intercity-n-scale-spur-n-echelle-n/?p=2889606 -
Hi Simon, I think I agree that the minimum wall thickness is a problem. It will be difficult motorising using Tomytec chassis in n scale for example, cos there won't be enough room. It's something I will be playing around with though! Thanks JDW for your support! I think I'll make a detail plastic version for those looking at a smoother finish. Cheers!

Trains printed in color (1:160)
bluemattersoda replied to SpoorObjecten's topic in 3D Printing, Laser Cutting, CAD & CNC
Huh, that's quite a clever method to make windows in N scale! I've been doing a glazing sheet which fits on the inside of the body shell using transparent detail...and it's very expensive! This looks like a good method. Do you guys think it'll work in HO scale? -

Thanks for sharing your techniques - I've been experimenting with coloured sandstone recently (here), and have been considering converting some of my N scale trains on Shapeways to coloured sandstone. Could you explain how you did the windows in a little more detail? did you have an acrylic sheet behind before adding the "krystal klear" (by the way, what is it?). Thanks! -
Thanks, I've already been down to the Brunswick terminus of Route 96 to get some images for a future E2 model. Tramtracker's very helpful for showing the tram number so you know when the E2's coming! I haven't tried that yet, but it may be difficult with the embossed windscreen wiper! Mate, I really don't know why you're so upset over me experimenting with materials. Of course it's got a rougher surface - that being said the prints are less rough than I had been expecting. I'm perfectly aware of different methods to colour, see below previous n scale work with decals. I also haven't ruled out making the E1 models available in FUD or HDA.

Hi everyone, Lately I've been experimenting with full colour sandstone 3D prints. I have noticed a lot of people are turned off buying 3D printed trains because of the painting - especially modern liveries with complicated graphics. This is the new E Class trams running in Melbourne - modelled in HO So here are the renders of the 3D model, in Rhino: And here are the test prints from Shapeways. I had two test sections done, one in standard Colour Sandstone, the other Coated. I think the uncoated version looks better. The Transparent Detail Plastic windscreens are a bit of a disappointment...more frosty than transparent. Also, the indicator lights didn't come out in the colour, so I will be revising in the model. The roof details are looking sharp though. I'll be revising the colour in the panel joints - as you can see they are bleeding onto the white. I also need to finalise how the chassis will work, but i'm happy with how this is turning out.

Time for a quick update! Again, I must apologise for the long time between updates. This will be a quick update again - hoping to have a more substantial update with painted model to show soon. Anyway, did a quick trial fitting of my 3D printed gears. Good and bad - it seems I get very close to getting it work, only to have something jam it all up. Here was the revised chassis model To summarise: Flexible Motor Shaft (WSF) - got the right balance between strength and flexibility so that it can help the universal joint turn (printed in WSF) Universal Joint (FUD) - FINALLY got this to work! Though I will need to up the size of the connected gear wheel. Wheel gears and Bogie Drive Shaft (FUD) - these mesh well and appear to turn correctly. The problem now is the WSF bogie frame. Seems that the fit is too tight to allow the gears to turn smoothly. I suspect this to be a scale tolerance issue - I've encountered this before in Shapeways WSF which may be smaller or bigger than what you design. This means everything is jamming up. The FUD parts are also very fragile - don't know how long they will last. I'm considering now if I should abandon this whole idea of making my own gears, and following the tried and true path of modifying a store bought chassis. While I'm close to making it work, it is always just beyond reach. Assembling the pieces is also very finicky, and in cost it works out about the same as buying a Tomytec chassis and modifying it. I'll give this some more thought. Until the next update!

Hi everyone, I've update the model as suggested by Ben A - please check out the thread over at 3D printing: http://www.rmweb.co.uk/community/index.php?/topic/113998-sbb-twindexx-intercity-n-scale-spur-n-echelle-n/?p=2647678. Here are some images: And the Second Class trailer (first class is also done): Anyhow, please let me know what you think. I hope to do another test print soon and will post photos when that's done.

Hi everyone, I've been very busy at the moment, so I've only now just finalised the revision to the original design as suggested by Ben A. Here's the revised cab - turns out the biggest problem was with the window and light positions. The shape of the nose has been slightly changed. I've also revised the motorised bogies (not shown), To save costs I've reduced the need for a WSF chassis - see the Second Class trailer carriage below. The downside is that there are no interior details - no seats, etc. I figured at N scale you can get away with this. First Class trailers have been completed as well. Anyhow, please let me know what you think. I hope to do another test print soon and will post photos when that's done. Alan

SBB Twindexx in N scale - Updated -
bluemattersoda replied to bluemattersoda's topic in Swiss Railways
You may be right Ben, it was very hard to get the front right. The frustrating thing is that I had several drawings from the internet and I used a front elevation to help with the front...I'm starting to think it was an early design sketch... I may try again soon -
Hi everyone, here's an update with photos as promised - Bombardier SBB CFF FFS RABDE 502 Twindexx in N Scale / Spur N / Echelle N I have to say I'm very impressed with the details in Shapeway's High Definition Acrylate - highly recommended by me for models. As you can see the details are crisp and angles sharp, plus it's cheaper than FUD and doesn't require cleaning. I've discovered that putting HDA into hot water to straighten out bowing can cause the plastic to become too soft. so be careful using that method. On the left is the glazing in transparent detail. I may reconsider cos they're somewhat finicky to install into the body shell, and are quite pricey (AUD$10 each carriage). On the right is a new thing I'm trying - optional paint masks to help paint some of the finer colours accents, especially on SBB's livery for this train. The motorised bogies need more work. Even though I've left the required clearance for moving parts, they were really stiff and caused parts to break when I tried to free them. Not shown are the universal joints which broke off. Good news is that the gears are meshing properly. Stay tuned for more!

Hi everyone, To keep everyone updated, I have received the first batch of prints from Shapeways. I'll be uploading photos over the next few days. The HDA shells are looking great! The bad news is the test print has revealed some major issues with the design of the gear system, and this will need some re-designing. On another note, has anyone been experiencing problems with Shapeways quality control lately? They've sent me the 2x body shells as per my model, but seem to have deleted one and duplicated the other without realising they are slightly different! I've reached out to get a reprint...but I've had to get reprints the last few times I've ordered with them due to them misreading/misinterpreting models (which shouldn't even be a problem considering that there's not interpretative work on their end). Shapeways US does the manufacturing for Australia, and they seem to be a bit slack on the QA front. I have to say I've never had issues when they were sending me stuff from the Netherlands...

The digital model of the Cab cars is almost done and should be ready for a test print this week. For those who are interested, progress shots are being posted over in the 3D printed section! http://www.rmweb.co.uk/community/index.php?/topic/113998-sbb-rabde-502-twindexx-intercity-n-scale-with-gears/ -
Hi everyone, It's been a while but I've been working on a new model. I'm hoping to have the model ready for a test print this week. This will be my second attempt at having the motor chassis 3D printed - the last attempt was close but in the end didn't work.This time round I'm using two universal joints per bogie rather than the traditional worm screw. In the meantime, here are the renders: I'm working on making the masks for painting. This came about after the finicky-ness of painting on previous designs. I'll post more photos when the prints arrive, and when I finish the carriages of course! I'm planning on putting this up on Shapeways for sale soon. Cheers, Alan PS: check out my previous models here; http://www.rmweb.co.uk/community/index.php?/topic/109915-3d-printed-trains-victorian-vlocity-sydney-waratah-sncf-tgv-edited/

Well done on the FLIRT - looks great! Can't wait til it's painted!
