Hi all biggrin.gif

I read someware on the forum "they don't do my model/region/colour/period". Well, how about a 3D. printer available on line, they are so accurate now that you could look up your requirements, say, from an Hornby catalogue site, sad.gif this would cut out over production and if they installed an ordering terminal at your local model shop they could cut down on stock and you would get your heart's desire, plus other benifits too numerous to mention. Imagine, bespoke modeling. biggrin.gif

Cheers Preston (Idea not patented)

Soon be big puff-puff time, the're tarting up the tracks down on the docks thumbsup.gif

It's a lovely idea - and one I doubt will come to fruition this decade in the form you list ... if at all.

First - I can't see either Hornby or Bachmann being happy with this - there would have to be stringent safeguards in place so that their designs didn't 'escape' from the model shop systems into the 'wild'.

Second - 3D printers are expensive - horrendously so. Yes, you can get a home model for under 1000 now - but it's nowhere near the resolution needed. Nor is it colour ... And I think the colour ones only have limited choices ...

Third - running costs for the printers aren't cheap. I think the setup cost of FUD (I think that's the name ?) is around $5, and then $3.50 per cubic cm of material ... And they're not fast either ...

Fourth - As to using the model shops ... well, why ? Ain't no way they'd be able to afford the decent machines, except maybe on rental - and that would cost ... Best go to the specialists (as now), no ? Get the materials costs down because of all the other people / industries using them.

Yes - all these things will be fixed in time - but by that point I reckon there'll be other alternates available that put 3D printing back into the 'was a nice idea, but ...' category (like Betamax ...)

Mike

PS - and yes, I'm looking into it myself for items I can't get tongue.gif In the short/medium term, this will be how some modellers get what they want, & then offer to the wider community ... It's already started.

There was an interesting feature on bcc site about a guy who did 3d printer art if you want to see what can be done with them.

I first saw one in person around 2001 and was convinced that everything I'd ever seen on startek had come to fruition, a week later they were touting that the properties of one particle had been transferred to another; essentially the first step in transporters.

Eventually we'll all just own our own 3D printer. We'll just buy blue prints from online and print out our locos and stock. Sort of cool and sort of sad huh?

Just wait, for the next 20 years while the price comes down....

The only ones I have seen are really naff. They deliver a horrible slightly oily plasticky artifact - completely lacking in "materiality" - totally unlike a characterful model of a weathered jinty, a 57xx or say an Midland signal box.
American architecture students love the process - they can go drinking the night before, call in to pick up a 3D print out on the way to the crit and spiel on everything about their project - except what it might conceivably be made of.

I reckon I'll be pushing up daisies well before the gizmo can replicate a weathered G2A tender cab early emblem.

And can the main manufacturing process currently used by Hornby & Machmann produce this ? No they can't - it's added on in finishing.

Please recall what we're dealing with here - it ain't a process that will deliver a finished product to you !

I do bespoke modelling - what the OP is talking about here is bespoke shopping.

Railway modelling is so much more rewarding if you ACTUALLY model stuff rather than just buy stuff. Otherwise you should just say you are a collector of model railways (not that theres anything wrong with that of course)

Hi all

May I, with your permission, elucidate, on what I meant to convey, namely that the devices mentioned were meant to be used initially only for scenic pieces and the like as metal components are no-nos (at present ). But who knows what will come along in the future?

The other side of the story is what we want out of our hobby? question.gif censored.gif

Anyway as we all know good ideas always find a good home cheers.gif

Or 6 years in the past even?

I'm sure we will see some amazing developments in this area in the near future.

Take a look at what one of the talented individuals has been doing with some of Bill Bedford's 3D printed bodies over at the LNER forum:










No, it isn't plug-and-play RTR, but it's a big step forward from having to roll a boiler or solder castings - at 55 for the raw printed body, it suggests a very exciting way forward.

In a round about sort of way some of us have been doing this for years without 3D printers nor computers.

OK I'll eat my words (earlier thread) - I do admit to being really impressed by that Bill Bedford thread thumbsup.gif thumbsup.gif thumbsup.gif :
http://www.lner.info/forums/viewtopic.php?...s+for+RTR+Locos

I didn't quite understand whether the handrail in the top image was output from the 3D printer.

I've always desired some diecast 4mm Midland Red buses (like a FEDD) from the Sinclair era, mebbee this might be the way - less coarse than cast resin.

Yes, the handrail was part of the output - I think just to see if it could be made to work. The consensus was it was better to leave it off for the modeller to form from wire.

The chassis is a Bachmann 04 - the new body is an almost direct replacement for the existing one.

There was a degree of fettling involved in getting the surface finish to what you see, but less work that if you had built one yourself.

As I said, we do seem to be entering a new age....

No, it's not, but it's certainly something that gives me a few ideas.
