Skinnylinny Posted April 25, 2018 Author Share Posted April 25, 2018 Well, my lunch break today concluded my last deadline-oriented modelling for a little while - I finished painting up and lettering the LSWR G6 model as designed by sem34090 of this parish, printed by i.materialise in their standard resin (a more expensive, but higher-quality print than their SLS Polyamide. The loco has been primed with Humbrol acrylic primer, painted using Humbrol spray acrylic Brunswick Green (not quite the right shade, but it'll do for a rush job!) and lettered with some spare HMRS transfers I had lying about. Whether or not the loco will remain in this state once it's returned after the coursework has been marked remains to be seen - sem34090 has turned his into a rather nice freelance 0-4-2 tank, and I'm very tempted to persuade the board of the Great Southern Railway to acquire a similar locomotive for mid-range passenger services. I think it would look rather smart in blue... 6 Link to post Share on other sites More sharing options...
sem34090 Posted April 25, 2018 Share Posted April 25, 2018 Thanks Linny! I was hoping to see this as a 0-4-2T in GSR Blue... 2 Link to post Share on other sites More sharing options...
Skinnylinny Posted April 25, 2018 Author Share Posted April 25, 2018 (edited) Keep an eye out, you never know... It would fill a useful slot in the roster, to be honest. I already have:Small 2-4-0T (Manning Wardle, in progress)Small 0-6-0T (Sir Samuel Vimes)Heavy shunter (un-named as yet, Triang Nellie body on an Electrotren 0-6-0 chassis, in progress)Medium goods loco (Havelock Vetinari)and thoughts for a 2-4-0 express passenger tender loco. The fleet is growing! I really must get around to making some baseboards soon, though! Edited April 25, 2018 by Skinnylinny 3 Link to post Share on other sites More sharing options...
Devo63 Posted April 25, 2018 Share Posted April 25, 2018 Heavy shunter (un-named as yet, Triang Nellie body on an Electrotren chassis, in progress) If it's a heavy shunter how about 'Sergeant Detritus'. Dave R. Link to post Share on other sites More sharing options...
Skinnylinny Posted April 25, 2018 Author Share Posted April 25, 2018 Ohhhhh that's a good one, I'm liking that. I'm still pondering a nice blue Terrier named Gaspode, and possibly a pair of locos (one rather larger than the other) called Esme Weatherwax and Gytha Ogg. The Manning Wardle might be Esme Weatherwax, and the heavier shunter Gytha Ogg... 1 Link to post Share on other sites More sharing options...
Devo63 Posted April 25, 2018 Share Posted April 25, 2018 I would have thought that a little Manning Wardle might have a name like 'Cheery Littlebottom'. Dave R. 1 Link to post Share on other sites More sharing options...

Nice job on it, too, by the way. Link to post Share on other sites More sharing options...
Skinnylinny Posted April 25, 2018 Author Share Posted April 25, 2018 (edited) I haven't sanded it down at all, except on one tank side where I left a fingerprint in the gloss paint! There's a little visible stepping in the cab roof, but the tank sides and horizontal surfaces are pretty much glass-smooth. The stepping on the boiler pretty much disappeared under two coats of primer and two of gloss acrylic spray. The cab roof stepping is just about visible still.

I bet it's cheaper than Shapeways' FUD or FXD. Might that be the material of choice for Sem to design to? Thanks Link to post Share on other sites More sharing options...
Skinnylinny Posted April 25, 2018 Author Share Posted April 25, 2018 I believe it's due to different printing methods - SLS (Selective Laser Sintering, as used for the imaterialise polyamide) seems to be a powder that is melted with a laser (hence the slight grainy surface), whereas the resin is a liquid which is selectively cured with ultraviolet light (the way in which they do this is rather cool, it's basically a phone screen with an ultraviolet backlight, so that the screen turns on and off individual pixels), and a setting liquid gives a much flatter, smoother surface. Traditional filament-based 3d printers take a long, flexible plastic rod and melt it, squeezing it out of a nozzle like squeezing toothpaste, building up the model in layers. This gives a very obvious stepping appearance, which is fine for things on a human scale (key fobs, USB key cases, etc) but rather coarse for modelling purposes.I've just received yesterday a very interesting sample piece, printed on a Formlabs Form 2 printer, and the finish is good enough that I couldn't distinguise it from a piece of (very finely) injection-moulded polystyrene. Matt finish, beautiful smooth surfaces around all the awkward curves (the layer thickness can be set from ~1 - 4 thou), and the printer will fit on a desktop next to a computer. The only problem is the price - a cool £3360 for the very basic model! I am, however, sufficiently impressed that I'm considering going to ask at the bank about a loan... 1 Link to post Share on other sites More sharing options...

TurboSnail Posted April 25, 2018 Share Posted April 25, 2018 I've worked with FormLabs printers before and probably will again this summer (for non-modelling purposes unfortunately) and they are very good - couple of drawbacks including very expensive resin, high waste and additional UV curing often needed (a separate expensive machine!). Be ideal for a hackspace/makerspace though, and can't be too long before they're down in price enough to suit the more fiscally challenged of us.

Skinnylinny Posted April 25, 2018 Author Share Posted April 25, 2018 Hmmmm. I've seen a much cheaper home-made UV curing box, made from a cardboard box lined in tinfoil with a load of ultraviolet LEDs in it - total cost about £20, much cheaper than the £750 Formlabs want for it! The resin is also expensive, granted... 1 Link to post Share on other sites More sharing options...
Skinnylinny Posted April 26, 2018 Author Share Posted April 26, 2018 Exciting news - a friend who apparently owns a 3D design, printing and prototyping company has offered me the use of his machine occasionally when it's not being used. I'm going to draw up some test parts to get printed by him. Unfortunately he's not in Edinburgh (or even Scotland, but Manchester!) so I'd still be at the mercy of the post. and having to pay for shipping. We'll see how the prices of bits pan out. 2 Link to post Share on other sites More sharing options...

Edwardian Posted April 26, 2018 Share Posted April 26, 2018 I do have a few friends in that part of the world. I should go on a trip to visit some time... It's a great town, especially if you're young enough to enjoy the night-life, and the Museum of Science and Industry is a railway 'must' for various reasons, not least of which is its inclusion of the L&MR station - but I'm sure you know all this.

Skinnylinny Posted April 26, 2018 Author Share Posted April 26, 2018 I may only be 26 but I've never been much of one for night-life. I'd rather be in a quiet pub with a friend or two and a half-pint of something actually drinkable than in a noisy, smelly, sweaty nightclub where I need to use sign language to be understood! Maybe I'm just prematurely old... I've been to the MoSI a few times but haven't managed to see their Planet running, which is a great shame. Does anyone know when they run her? I can't find anything on the website... 1 Link to post Share on other sites More sharing options...

MoSI is a good place to visit, there's a cut up loco showing how steam is generated and used to drive the (motorised) wheels, a goodly selection of locos, mill engines and a wonderful whiff of gas when they're running the stationary gas engines! Across the road there's the aeroplanes, and you might even see the Manchester Baby in operation.... Edited April 26, 2018 by Hroth 1 Link to post Share on other sites More sharing options...
