Title: 3D Printing
Post by: Stevie DC on April 30, 2011, 07:52:47 PM
Hi all, first post here, although I recognise some of you here from 'the other forums'!  :evil: :smiley-laughing:

Anyway, I've been playing around with CAD and 3D printing for awhile now and would like to share some of my current projects. The designs are currently waiting to be printed by Shapeways in a new ultra fine detail they are testing.

First is a K3 body to convert a Farish V2 chassis. This will be the second one of these I've had printed, the first being in wax which then got investment cast - the caster placed sprues on the external detail!!!  :thumbsdown:  Hopefully this version will be usable! The Farish chassis has a slightly incorrect driving wheel spacing as well as the wheels being a little large (oversized driving wheels on an n gauge loco!!!!) but has the correct valve gear, etc so for me its a better option than say a Crab.

Next is a Dia. 120 Passenger Break Van (Pigeon Van). I'm really going to try and push the boat out here with vac cylinder, buffers, NEM pockets, and printed pinpoint axle bearings! Still needs brakes adding but excitement got the better of me!

(http://i1112.photobucket.com/albums/k481/Atso-Cad/N%20Gauge%20LNER%20CAD%20Work/PigeonVan.jpg)

Slightly more mundane is a Gresley standard 8'6 bogie.

(http://i1112.photobucket.com/albums/k481/Atso-Cad/N%20Gauge%20LNER%20CAD%20Work/GresleyBogie.jpg)

Finally, trying to push the new material option to the limit is this mock up of a lattice signal post - the cross pieces of the lattice are only 0.3mm thick!

(http://i1112.photobucket.com/albums/k481/Atso-Cad/N%20Gauge%20LNER%20CAD%20Work/SignalPost.jpg)

I hope that you guys (and girls!) find these of interest, I'll post some pictures when I get the prints (in a couple of weeks hopefully!).

Cheers for looking

Steve

Well welcome to our corner of the www :wave:
I dont do other forums so we are new to eachother :smiley-laughing:
Ive always loved the idea of CAD but never been able to afford the software or have the time to learn how to use it, so I shall be intersted in you results just to see haw far it can be taken

Very interesting and great CAD work.

From what I have seen of 3D printing it still has quite away to go to get a smooth finish, so will look forward to seeing the results of the ultra fine material but I will be surprised if it is able to give a good rendition of the loco boiler. Have you considered approaching the guys at Renedra who have a very good reputation for injection moulding:

Hi all and thanks for the positive comments!  ;D

Jon and Tank, yes CAD did take a little while to master as with most things its about finding out what programs and techniques work for you.

John, I've thought about making kits before but not yet done anything. At the moment this is a hobby but if that changes I'll asked Tank if I can put up a shameless plug here...  :smiley-laughing:

Truffles with 3D printing it really is a case of you get what you pay for there are some processes out there that really do deliver - for a price. You are right that most bottom end printing processes cannot capture the shape of a boiler very well but this seems to be improving. I've recently had some SLA (laser cured resin) models made with a layer depth of 0.2mm this doesn't work well with the boiler but some rubbing down did cure this to an extent. I've got a couple of pictures, the first is of the K3 which was printed in wax (at 4000dpi!) and case in brass - this was going to be a kit but unfortunately I'd made a mistake in the design which couldn't be made good without affecting the quality of the master  :'(

(http://i1112.photobucket.com/albums/k481/Atso-Cad/3D%20Prints/K3RightSide.jpg)

The second is of an GNR (LNER) Atlantic which was printed using 0.2mm SLA and rubbed down. Hopefully Shapeways new material with it's 0.032mm build depth will provide a better (most cost effective) result.

(http://i1112.photobucket.com/albums/k481/Atso-Cad/3D%20Prints/LNERC1SLAPrint.jpg)

Finally, I've been on holiday to Pickering this week. I took the laptop and after around 5-6 hours had this to show...

(http://i1112.photobucket.com/albums/k481/Atso-Cad/N%20Gauge%20LNER%20CAD%20Work/BogieBrickWagon.jpg)

Hopefully I'll have my first set of prints from Shapeways sometime within the next 10 days... demand for this new material exceeded their expectations and they've got some delays as a result...

Unrebuilt Patriot, not being an LMS man I had to remind myself what one looked like - about how I remembered actually!!!  8)

The Jubilee or Royal Scot from Farish would seem to be a good choice for a chassis but what about the tender? The new Farish models use a tender drive which seems to have a very different wheelbase to the Patriot. Would people be prepared to accept and slightly overlong tender here?

Hello Atso,

I'm quite interested in this 3D malarky - the potential is quite exciting, but I don't know much about it.

Could you do a quick 'idiot's quide' to the basic steps involved please? And what sort of prices are we looking at?

For me I'm thinking of things like pre-war double-deck London buses which nobody makes in any shape or form and would be time consuming and flimsy if made in Plasticard, and equally time consuming but more expensive if I got someone to make an etch for me.

Thanks

First step is to draw up your model in a CAD package.
Then you eport it as an STL file.
Use a package like Netfab to check that the file has no 'holes', multiple shells, etc
Upload the file to an agency like Shapeways.

A bus model that I tried out cost about £9 and that was just the basic body, no floor, seats  etc
The material was 'White Strong & Flexible' which has a slightly rough finish and can be subject to layering.

New material 'Frosted Ultra Detail' would cost about £21 and is supposed to have a much better finish. I am awaiting my 'test' components, so I cannot say how good the new material is yet. I am due my parts fairly soon.
Title: Re: 3D Printing
Post by: Stevie DC on May 09, 2011, 12:38:43 AM
Hi Southern Boy,

Bob (NTrain) has pretty muched sumed up the process. However be warned that learning a CAD package is a real learning curve, you should be able to pick up the basics quite easily but figuring out those hard to model areas can take some time.

Bob, having read the spec for the Frosted Ultra Detail it compares quite well against my Solid Scape model (the K3 pictured previously) with a similar layer depth. To be honest 800dpi resolution works nicely for printing photos so I'm hopeful that this will at least meet some of my expectations without the costly investment casting of a wax print! Looking forward to hearing about your opinions on Shapeway's newest material in due course!
Title: Re: 3D Printing
Post by: Southernboy on May 09, 2011, 07:27:13 PM
Thanks for your very helpful replies NTrain and Atso, I'll be keeping an eye on this thread to see how projects develop.

I'll probably be ok at getting the basics of CAD as I work in design (2D) and have a basic grasp of illustrative / layout programmes, but as you say, figuring out more complex shapes/angles and curves (especially those that intersect) will be a bit of a learning curve.

To be honest £21.00 sounds reasonable for a basic shell - an etch would cost at least £10.00+, still requires assembly and also wouldn't necessarily come with parts like seats and wheels.

Don't hold your breath on me making a bus (or similar) just yet - I'm just gathering thoughts and information at the moment.

Thanks again!

I haven't worked out the method of adding pictures to posts yet, or I would put up a picture of my bendy bus.

What type of buses are you looking at anyway.

Shapeways have just anounced a 'White Strong & Flexible... Polished and Smooth'. Just ordered some samples to compare.

I have been designing stuff in Rhino 3D, which is a high power package. After 5+ years, there are still some areas I am having difficulties with.

Your pictures just popped up as I was writing this - they look good  :)

The sort of bus I'm thingking of is the London NS type:

http://www.doubledecker-bus.com/2009/11/ns-type/ (http://www.doubledecker-bus.com/2009/11/ns-type/)

Both open and closed-top versions.
They were fairly common from the mid 1920s to late 1930s, although having said that until 1933 and the formation of LPTB bus companies in London were still privately run so a variety of types of bus in different liveries would be seen on the streets. It's one of the aspects of London I'd like to capture on my layout.
Title: Re: 3D Printing
Post by: NTrain on May 09, 2011, 10:01:52 PM
3D modelling is all about compromise. Each material has it's own minimum requirements.

However, there are practicle requirements as well. I bought a model bus designed by a European modeller and he had designed it to minimum tollerences, but the walls could not support themselves sufficiently and bowed inwards.

My early career was allied to engineering and a lot of that has stayed with me when I design. That early career may also be one of my stumbling block as I was trained in draughtsmanship (2D), good old fashioned pens and tracing paper.....................

Welcome to the site Atso.
Theres some nice 3D work people are doing on here.
Well, I have been dipping my toes into the realm of 3D modelling myself.  :o

(http://i869.photobucket.com/albums/ab257/Kilnevan/The%20Workbench/gscattle2mm.jpg)

The picture above is of my 1st attempt and may well need reworking.
Below is my second attempt.

(http://i869.photobucket.com/albums/ab257/Kilnevan/The%20Workbench/RoundendedopenwagonforPeco10chassis.jpg)

Being a little financially challenged (Skint!) I'm learning on Google Sketchup as its FREE!  :thumbsup:
I know some seasoned 3D modellers will think 'yuck' at that but I'm pleased with what I've drawn up.
If you've never tried 3D modelling Sketchup is a very cheap way of trying it out!  :smiley-laughing:

(http://i869.photobucket.com/albums/ab257/Kilnevan/The%20Workbench/dser18701stcoachPeco15chassis.jpg)

My 3rd attempt above was a lot more adventurous.  ;D
Now I'm just waiting to see if these are printable and if so wait for my test prints to arrive in the post!
Exciting times ahead...  :)
Title: Re: 3D Printing
Post by: Stevie DC on May 10, 2011, 12:55:55 PM
Thanks for the Welcome moogle! I think Sketchup is a wonderful tool to start 3D modelling in and I've seen some nice prints done with it. The only reason I moved away from it so quickly was because I wanted to model a Gresley domed coach roof which Sketchup didn't like too much.

NTrain, I like your bendy bus! Great model, shame its right out of my period of modelling otherwise I might have been tempted to ask for one!!!  ;D

Your right about ensuring that a 3D model can be printed into a practical physical model, I experimented with some really thin wall sections mhen I first started with this. I've managed to print small items with an overall wall thickness of 0.75mm which are ok but don't apply too much pressure when handling them! I think thinner walls are possible but would need some kind of bracing designed in.

I don't know how much you read on the Shapeways forum but there was a great tip on there about soaking White Strong and Flexible in superglue and the sanding down to get a smooth finish. I've tried in on one of my older models and it really made a difference. Now that Shapeways has just launched a polished version of this material it will remain to be seen if this would still be required.

Southernboy, love those old buses, much more my era of modelling! Have a go but I think you'll find the cab roof a challenge at first - you'll get the hand of it though! as NTrain said there will be compromises to make but I think that's true of all modelling. When presented with a detail that'll be difficult to reproduce I normally ask myself if it'll look worse modelled badly or worse if it is missing. I might be opening a can of worms with this statement but I think that with N Gauge if you can make it believable then its ok if its not quite to scale (within reason of course!). 
Title: Re: 3D Printing
Post by: NTrain on May 10, 2011, 04:59:46 PM
The tip about using superglue seems to work fairly well, until you have inset positions on the model, that also want to be smoothed.

I've used a small amount of touch up primer (the pen/brush kind from Halfords) and some carefull work with a glass fibre pen in recessed areas with some success.

I got my first shipment of bits from Shapeways yesterday. Unfortunately it was only the Gresley bogies which I'd ordered in a different material be mistake. There are not bad but suffer from the usual white strong and flexible material issues. On the plus side the take Farish wheelsets and roll very freely with little cleaning up. I might sand them smooth or wait for my replacements in the new material instead.

Incidently I've just see some pictures of an N gauge multiple unit(?) on the shapeways forum. I've no idea what the prototype is (it isn't British) but it does look very very good!  :thumbsup: Link: http://www.shapeways.com/forum/index.php?t=msg&th=5210&start=0& (http://www.shapeways.com/forum/index.php?t=msg&th=5210&start=0&)

They became inundated with orders and announced delays while they arranged more capacity.

My 10 order period finished today. I've received my Gresley bogies in white strong and flexible but my frosted ultra detail order is still outstanding. I'll be contacting Shapeways today but as NTrain said they've been inundated so I'm not too fussed if it takes a little longer...

NTrain & Ntastic please post some pictures once you've got your orders!!!  :thumbsup:

Hi Painbrook, I would guess bits in this topic are a little like reading another language. Most certainly its been a steep learning curve for me over the last few years. I've just taken delivery of Brian Haresnape's book on Fowler locomotives to learn a bit more about what came out of Derby...

Here is a picture of my test components.

(http://i1194.photobucket.com/albums/aa372/ntrainuk/3D%20Models/DSCF1273.jpg)

A little disapointed that two of the models have 'bowed' slightly.

The BVA wagon body and the DMU bogie sides.

Will play around with these before I pass final judgement. However, the quality of the printing seems the best I have had so far.

I can show pictures of each individual part if anyone is interested.

I'd like to echo the Captain's comments, I think that the prints look very good. Interesting to see that some of the parts have bowed slighty, could some warm water help with this?

Well I heard from Shapeways yesterday that my models were printed.
Thats the good news. The bad news is that my open wagons broke when printed and that my cattle wagon had warped sides.  :(
Walls too thin obviously so I'll have to redesign them. Everything else printed so now I wait for UPS to deliver!  ;D

Thats right. You draw it, they make it. (Print it)
It is possible to buy a printer and print your own if you have a large bank balance!  :smiley-laughing:
Its not that expensive, if it was, I wouldn't be using it.
You pay for amount of material used plus a start up cost to cover use of the printer, staffing etc.
The postage costs are factored in already.

My friend is a freelance designer (CAD, graphic, etc) and starts at around £25 per hour if that's any indication. I would assume that this is somewhere near the going rate but someone might be able to do it cheaper.

A BMW would be an interesting project to start with. I tried to model a car which proved very difficult to try and get all the various curves right - as has a streamlined B17 to date!

I've got my prints from Shapeways, although I've managed to break a couple of the details on the Pigeon Van already, the next print will have these weak spots beefed up a bit too! Also my printed NEM pocket hasn't worked out quite as planned, the coupling fits but won't move up and down, something else to be fixed going forward. Pictures to follow shortly.

I've been dabbling with Google Sketchup but have yet to create anything vaguely looking like a useable building, let alone an item of rolling stock. Really need to sit down and learn the subtle arts of the third dimension. Would love to be able to do some of the curved front ends of modern rolling stock, such as the Class 180.

All the Electra artwork as well as the Model Rail building kits have been done 2D in Freehand.

Today my parcel from Shapeways arrived. So exciting!  :)
I carefully opened it and got out the coach I had designed from its packet.

(http://i869.photobucket.com/albums/ab257/Kilnevan/The%20Workbench/thecoach2.jpg)

None of the detail below the windows had printed. So I've gone wrong somewhere!
Then I turned the coach around to see the other side.

(http://i869.photobucket.com/albums/ab257/Kilnevan/The%20Workbench/thecoach1.jpg)

This side hadn't printed at all!  :o
Well, a tiny bit on the ends and bottom.
The ends and roof were fine.
Obviously I've a lot to learn doing this 3D malarky but I'm not put off as I see its potential.
The other item in my parcel was a pair of station name boards. (Only one shown)

(http://i869.photobucket.com/albums/ab257/Kilnevan/The%20Workbench/thenameboard.jpg)

These had printed perfectly. They are slightly flexible due to their thinness but the 0.1 mm high lettering is quite crisp.
If you can't see it properly in the photo it says 'Kilnevan' with 'Cil Naomhan' underneath as I needed dual language ones.
These will look a treat once painted and mounted on posts.
So I'm happy, I just need to practice more 3D drawing and amend my designs.

Thank you. You're right, it's exciting!
Having started learning last year how to make silicon rubber moulds and cast in resin I can see me using both processes at once.
Using 3D printing to make a 'master' to make the mould from will be easier than making one from scratch and more accurate.
In theory at least!  :smiley-laughing:
I got a book a while ago called 'Google Sketchup 7 for Dummies' which I find quite helpful.
Though I tend to play and learn 1st, then read the book!  :o

My brother's building himself a RepRap http://reprap.org/wiki/Main_Page (http://reprap.org/wiki/Main_Page) so once he gets it working, we'll be seeing if it's practical for any N Gauge models. (probably only more basic ones as the resolution is only about 0.35mm).

Interesting bit of kit those RepRap's.
Resolution's not brill as you say but for what they cost you can't expect the earth!
Even if you could only make basic shells to add detail to it'll be worth it as you can
then make as many as you want without needing a mould as you would in casting.

On closer inspection of my station name boards I noticed a few vertical lines.
I filled these in using superglue, not a method I've used before but it works.
Only trouble is, it made painting the letters harder!  :smiley-laughing:

(http://i869.photobucket.com/albums/ab257/Kilnevan/The%20Workbench/thenameboard2.jpg)

So, having only done one, I'll paint the second one before I fill in the gaps.  :o
And since I've made these and painted one I found out that the English spelling should be at the bottom! Not to worry...

They arrived a few days ago. Coach sides were ok. The wagons were even better.

Certainly looks a good generic round ended low wagon.

For the etched kits I've been using the Peco 9' chassis because most of the wagons I looked at were 9' or so wheelbase. The Peco 9' chassis is much much better and more accurate and as it is a kit you can easily amend the brakes or trim the ends down to make the slightly shorter 1880s style body fit nicely.

The Mill Lane Sidings GWR wagons suggest adding a bit of plastic rod to get the look of the flitched iron chassis which is a nice idea.

Thanks guys!  :)

Good idea, I agree.

I actually based the dimensions on a Peco 10' chassis, just don't have any at the moment.
Was surprised it fitted the Farish one, but it does!

Tank, EMU's would suit this technology as they are quite square and flat sided compared to steam era stuff!
(I know there were EMU's around during the steam era, I was meaning more modern built ones.)
I think the main thing would be to design it around a chassis rather than make a scale body then find a chassis.
Purists will hate that idea!  :evil:

Hey Moogle that wagon looks great! Where are the coach pictures?

I'm still waiting for my MK2 FUD orders, unfortunately I've not got any pictures of the originals yet... I'm also working on an LNER 51ft non corridor full break with close couplings as well!

I definately agree that it would be best to adapt a body to fit an available chassis for any MU or loco body.

Wow it seems an age since I've had any news on my projects. Luckily the UPS man arrived earlier this week with a package from Shapeways, inside were...

They look excellent!

In other news, my brother's RepRap (self built prototyper) just printed its first cube! :)

Thanks guys!

matt-b yes there was quite a bit of work involved designing this model and several revisions of the design before I was happy with it - hopefully others will be too!

Sithlord - I'll have them in production as soon as I've finished cleaning up the masters. Hopefully sometime before the end of the year!!!

Tank - thanks, any luck with getting information on you EMU?

Zwilnik - hows the cube, I'm very interested in the long term development of the RepRap please could you post some pictures of the machine and its prints?

No luck with my EMU's.  I just found a guy who makes the Class 455 and 456 in OO gauge.  I got a reply today that he has no plans to make them in N.  I asked politely about helping with any fees to convert any CAD drawings he had, but he didn't reply to that particular question. :thumbsdown:

I have however just downloaded Sketchup, so I might one day have time to learn how to use it and make the 455.

It's a bit rough at the moment but getting better as he tunes the temperatures and we tweak the fairly iffy firmware to get the bugs out. I'll sort some pics later :)

Well if Sketchup fails and you can find some good quality drawings, let me know and I'll see if I can help.  :thumbsup:

Here's a vid of my brother's RepRap printing a 20x20x10mm test cube (it's currently in bits to sort out some issues that came up while printing the test cubes).

Hi all,

The masters have now gone to the casters and delivery is expected by mid November. We hope to have our web site online by mid October to take pre-orders.

Not been able to master Sketchup or any other software but I am looking to get this Russian loco done to go on a chassis for a French 7001 or the RENFE version by Arnold?

It's a bit of an ask, but I have lots of drawings photos etc. Anyone like to give it a go?

Hi,

That is a very interesting looking loco, I would be happy to draw it for you. Drawing 3D printed shells to go onto working chassis is something I do; have a look through my blog site and you’ll see previous drawing projects.  I cannot promise to jump onto it right away but if, as you say, you have drawings and photo information it will make it a lot quicker.

If you want to talk about it in more depth please PM through this site or you can contact me through my blog site.

-James

Unlike in 00 Gauge, there are some notable gaps in BR SR models in 2mm Scale. However, with the continuing advances in 3D printing (printers and material), given the marked slowdown in new RTR models in N Gauge, I'm hoping to convince someone, here, to make a 3D print of one of the 600 series Push-Pull sets (I have scale plans in digital format) as well as one of the last 'Gate Stock' pull-push sets (someone already makes a 3D print of one of the earlier 'Gate Stock' pull-push sets which did not last into BR days). However, I'd also have to get someone to convert a Dapol M7 into a long-frame one (it has been done by a forum member) and add pull-push equipment (a 3D print of the air pump should be simple). Maybe these two types of pull-push sets would make good crowd-funding projects?

Another 'gap in the market' is 3D printed models of the various tender types which were attached to Bulleid Pacifics, including the ones attached to Light Pacifics (which it appears Graham Farish are not going to release new upgraded models of), and a powered 'Watercart' tender to replace that provided with Union Mills T9 models (and for other BR SR locos., too), although, again, this has been done, by a forum member, using a metal tender kit and a German powered chassis. The tenders attached to the old Graham Farish Bulleid Pacifics really need replacing with true scale ones of the correct types.

Lastly, given the lack of LSWR type water cranes, a 2mm Scale 3D print of both the platform and ground mounted types should be quite easy and inexpensive but are there any suitable scale plans?

I have asked the chap who does the gate stock if he will be producing other push pull and Maunsell open 3rd - which was included in the 6xx series, this is his reply

Quote
I am looking at coaches. The gate-stock I did, did last into the 30s, converted. As I have drawings I will eventually do others. Other coaches dependent on getting drawings. I now have books of drawings for LSWR, so probably that would be my first choice, plus any southern push pull coach.
 

It shouldn't be to difficult to hack a Dapol BCK into a driving end, but so far I've found hacking to an open 3rd is not easy with the recesed doors, same goes for the restaurant car which I also asked for.

Many thanks, Mike. I also want a BR / Maunsell Restaurant / Buffet car.
