Bernard Lamb Posted July 30, 2013 Share Posted July 30, 2013 you have to have people who experiment or there will be no progress. No problem with that. As long as you are aware of the potential problems. An old boss of mine had a pet hate. What he called busy fools. You and me seem to be a world apart in regarding how to cost a product. But what do I know with only 30 odd years in a production engineering environment. Plastic printing is very old school these days. Why not go for broke and try printed titanium? I would go for some nice bling bike parts, as cyclists have more free cash than railway modellers and a British winner of The Tour de France will provide you with free publicity material.

jonhall Posted July 30, 2013 Share Posted July 30, 2013 So lets see the CAD file you intend to print from, because that's the first bit that need to be right to make anything worthwhile, and its a lot more than just the drawing - I've seen a lot of nicely drawn, but totally inaccurate CAD where the operator just doesn't understand what he is drawing, or the base research is wrong. Once you have something to print, then you should think about a printer, but not a printerbot - those are a great training tool for schools, and an interesting toy, but not suitable for the sort of application you propose. Or have we all fallen for a troll? The Hornby mk4 has plenty of faults, but is available cheaply secondhand, and will require a lot less work to put right than even a state of the art 3d print.

He is obviously a bit young and enthusiastic with lots of ideas buzzing in his head. Calling him a troll is over harsh and unfair. Link to post Share on other sites More sharing options...

Adamphillip Posted July 30, 2013 Author Share Posted July 30, 2013 first product i plan on making is an enclosed steel wagon as a test like so: models will come in 4 pieces; chassis, body and 2 bogies (depending on model in question) you will have to fit your own wheels and couplings.

Adamphillip Posted July 30, 2013 Author Share Posted July 30, 2013 The hood on that Shimmns will be an interesting exercise in learning CAD I know but it will hopefully pave the way to people not relying on the big companies to make models in china. (edit: if I can prove this to be a viable means of manufacture people will be able to download files and make their own models in their home) Link to post Share on other sites More sharing options...
Adamphillip Posted July 30, 2013 Author Share Posted July 30, 2013 would it be a bad idea to make long coaches in several parts if the parts are too long to fit on a standard 3d printer? Link to post Share on other sites More sharing options...
RMweb Gold Revolution Mike Posted July 30, 2013 RMweb Gold Share Posted July 30, 2013 I can't help thinking you are barking up the wrong tree. At the moment the majority of affordable home 3D printers are nowhere near the quality needed. They might be in the future, but at the moment you either need to invest in a better 3D printer or send it to someone like Shapeways (at a cost). The ideas you are talking about are all good (though you are far from the first to think of them) and will happen eventually. Design tolerances are rarely scaleable so that means messing with things like wall thickness and working out what compromises you are prepared to make on smaller detailing. Just try printing something simple like a cube and see if you would be happy with the surface finish on a coach or wagon - my (educated) guess is you wouldn't.

jonhall Posted July 30, 2013 Share Posted July 30, 2013 nope they are injection molded Every time you put finger to keyboard you get slightly less credible - following the link TrustyTrev posted http://www.topptrains.co.uk/acatalog/Topp-Pots.html reaches a product page, go to a product then follow the like that says 'click for more information about this product' and you get 'The pots were developed using the latest 3D printing techniques and we think they really show off the detailing well.' - not injection moulded! There are lots of people on this forum who can and will help you, but if you don't listen, then they will become increasingly impatient. Jon Link to post Share on other sites More sharing options...

Adamphillip Posted July 30, 2013 Author Share Posted July 30, 2013 So do you have a drawing of this wagon? What are the running numbers/UIC codes? Jon It will be a blank kit so you have to add you own liveries and running numbers, I am currently trying to make the model for the wagon, I won't have the printer till september/october time and the printer itself is a kit so i have to build that.

Adamphillip Posted July 30, 2013 Author Share Posted July 30, 2013 when I get the printer what do you guys think I should make first? and what scale? Link to post Share on other sites More sharing options...
Alastair-I Posted July 30, 2013 Share Posted July 30, 2013 I suggest you start here. Amongst other things, you need to know what you can produce first, then work out what you should. Lots, and lots of test pieces to determine the capabilities of your workflow and the machine. (in case you're worried about sarcasm, we're all being serious. You can't treat a business as a hobby if you want to be taken seriously. Everything you've said so far has been another point on the numpty-scale. You need to start thinking and planning, not guessing and making it up on the hoof. I will make no allowances for your age, anyone can be successful in business whether they're fourteen or forty) Link to post Share on other sites More sharing options...
