3d printers and printing

Postby bootneckbob » Sun Jul 26, 2020 7:04 am

Hi, just wondering who has invested in one for their model railway. I'd never considered it until today after seeing a couple of videos with people recommending them. It's a black art to me but I'm modelling Exeter St Davids and when it comes to the steel works for the canopies and the buildings a 3d printer might be usefull?
So, is anyone using one and if so how would you go about printing lamposts/supports etc?
Thanks.

There's a lot of experience here:

And many other places if you search the net.

Thanks for the info. Does that mean you've got one tho? The main part of my question was who on here is using one? Just how mainstream are they. I haven't seen any of the main youtubers with them yet although I have seen them getting parts done.

It reminds me of the intro of computers back in the 80s. To some writing code to get in to repeat you name on the screen was easy and interesting. To me it was another language (litterally) and pointless!

Guess who's laughing now?? :roll:

I've got one. It's a Coocon Create Model maker which is a re-badged Wanhao I3 Mini. I got it for under $300 from Aldi (In Australia). I'm quite happy that I own it.
The major part of it is that you will need to learn how to use a 3D CAD program.

Read the reviews. Watch some videos. Have a go at designing something in CAD.

No I haven't: because my model railway hobby is centred on operation, rather then running the loco, carriage and wagon works. It's operations automation I am pursuing, having been one of those very taken by computers from the 1960s on.

Not very mainstream at all. Sorry I didn't answer your question, I'll not bother in future.

I’ve got one, two actually, first arrived with a couple of parts missing, so they sent a whole replacement printer). It’s the cheapest of the cheap. It’s an anet A8, I’ve only had a little play around, as we were moving house when I got it. I’ve had some reasonable results, I printed some buffer stops which clip on to the track, and a Santa’s sleigh.

I’ve also got the files downloaded for stephensons rocket, firefly, and some others. Only used files made by others so far, and downloaded from thingiverse. I’ve had a play around on a website called tinkercad, which seems good. Others get some good models from there. I managed to draw up a 3D printed bridge, but I never got around to trying to print it.

If you’ve got some spare time and money, go for it. My printer was under £60.

Hi...2 here though I mostly use the 1 which I can get the bset finish from now.
Mostly rolling stock for myself and to sell to help fund the hobby.
I design all the models myself and being a drafter that is probably a huge advantage, Though ive seen some great items by people learning as they go.
Link to some vids on my layout.

Thanks for those replies. Bigmet, if your reading this I did say thanks for the info so no need to have a strop on. If you can get yourself wound up on a railway forum the internet really isn't for you! Oh, that's meant to be a joke or mild humor at the very least. :roll:

Hi...Started with GEETECH I3, a prusa type clone.
My goto is a Creality cr10s, ive found th ebiggest thing is the profile you slice with.
Currently using Cura as a slicer with 'cheps" profiles from his web site.
Ive looked hard at resin but still get a result im happy with using this system.
Being a draftsperson im half way there I guess as drawing is easy for me.
Pic is some GWR Aero crates printing.

Excuse my ignorance Amanda, I've no idea of the terminology.
What is a slicer and Cura and what do they do please?
Thanks

I bought "Laser cutting and 3D Printing for Railway Modellers, Co authored by David Renshaw who is a member "El Davo" here. It Easy to follow uses items relevant to railway modellers and covers the various bits of software needed to produce the 3D Virtual Model, what you can get wrong and then all of the other software tools up to the point of pressing PRINT. Yes I have a printer, a Da Vinci mini, which I bought despite it having a chip hidden in the spools which means it will only use their own (more expensive) filament. I will almost certainly buy a newer model without the metering as I have ready home for this one which won't mind the extra cost of use.

When I looked this book up it was listed as "Laser Cutting and 3D Printing, I thought they had the title the wrong way round but didn't go a and check my copy. I was right today Amazon tried to flog me another copy, Why?. Here it is. Gone up a bit since I bought it. I think there's a paperback edition as well. It's a great intro because they go straight into using the hardware and software that suit railway modelling tasks.

Cura is a slicer.

A slicer takes a 3D object (as a file) and slices it into layers for a 3D printer.
The printer then prints each layer on top of the last to reassemble the object.
