3D Printing

A Question for anybody that uses a 3D Printer have you printed parts or objects and used them outside permanently ? I don't mean a wagon that you bring back in when you have finished running , I mean things like platform clutter parts of building etc.that stay out side all the time. Contemplating buying one as the price seems to be coming down and the quality going up and some of them don't like like a home made science project anymore :) . I can think of lots of things that I could print with one but only if the stuff can be left outside and cope with good old English weather.
 
Good question!

UV stability can be improved if the item is painted, but the material used for printing will have a bigger impact, I expect?
 
But try and learn the software first.
 
I have heard that Dave, but my point is - the printer is no bloody good if you cant use the software.
 
I believe aldi are releasing their 3D printer in UK this November for about £300 .. might not be a bad entry level bit of kit for price.

i disagree.there are so many designs avayable (many of them free) that one can print for years, without learning to design in 3D.

You're right, but this is only any good if you wan't that particular thing, and some of the railway offerings are pretty dire. Moreover, they are rarely in G scale so you need the software to scale the object up or down and that can produce its own complications. Tinkercad is easy to use once you grab the principles but is fairly useless for precise work on rounded objects, I have found. In my opinion, that 123dapp is the best free software around. This is no longer available from its original publisher, but someone on this forum did publish a link to where it may still be found. The very best free software around is Blender but trying to use that is probably going to add you to the case load of an overburdened NHS or your nearest pub landlord's list of his favourite drunks!
 
yes, i tried blender... and it seems to need users with a slightly higher IQ than i am.

for rescaling, cutting and/or repositioning imported designs i use netfab or netfabb(?)
(even i can master that)

if you want enough designs, go to yeggi.com
that is a searchmashine, that searches them all. thingyverse, cults, 123, you name it.
my favorite searchfilters:

railroad
railway
1 32
open railway
cart
car
wagon

and (because i'm cheap) combined with
free
latest

That causes some more problems then! I was going to look into getting a 3D printer from Maplins, there is a shop close to me and the manager seems very helpful and has offered to demonstrate the machines, this, I thought was usefull, as if i have problems, there is someone to go and talk to as opposed to trying to find a solution on YouTube or where ever. There machines start at about £500.
Perhaps we could do with an extra heading on GSC just to deal with 3D , where if any 'clever clogs' came up with a design, it could be uploaded for anyone with a printer to share? And also give tips and hints? It would, after all, be model railway orientated.

After searching the net more on filaments did find one that says it is UV resistant called ASA filament,no doubt harder to print than the usual stuff , Nylon is probably good for outside use it says, again no doubt harder to print and probably harder to paint. Was hoping to find information about what filaments people have printed and left outside with or without a paint finish on them and if they degrade but as yet not found a lot on that subject.

If Aldi do sell their 3D printer again and it's the same as last time then it's basically a re-badged Wanhao i3 V2.1 Duplicator which sells on Amazon for £295

In my case I am lucky I don't need to learn to use 3D software, I already use the best in my job, producing 3D models/animations etc. :) I have downloaded and installed a slicer program that previews the output to a printer to get an idea what controls you have on the way things print. hope Santa has lots of printers in stock :rofl::rofl:

Just found The Aldi link for their printer selling on the 19th of November it look like they have up-graded it to a newer version, it looks like a re-badged Wanhao i3Plus Duplicator

I do not think that's a bad shout .. sounds like a good resource should others be happy to share models etc.

Begs the question, from those in the know, ...

Is it any good??????????????? :wondering::wondering:

Presumably, a £600-£700 model would produce more refined results?

Am guessing speeds will be about the same, as the filament takes the same amount of time to set, whatever printer you use??

Typically the more you spend the greater the result you get on your printed models ... now that being said for most use cases the items produced can be vastly improved via a routine of sanding (working up through the grades of paper). Once finally painted you can get some very impressive results indeed!

I guess it depends what you plan to make with your printer :) I for one can see a 3D Printer being a great tool for manufacturing add on accessory's such as Snow ploughs etc for locos.
 
Hi Guys
I have been 3D printing now for about 10 years now and have been printing materials for outdoor use in g scale for the last 5 years or so, I trialed sleepers and building my own track with some success a friend of mine has taken this to the next step and has built a complete railway, the test section i started with has been outside for 4 years now in the direct sunlight through Australian summers with no structural deterioration only some mild discoloration on the white sleepers, the plastic used is ABS (Acrylonitrile Butadiene Styrene) Take into account that the UV here is considerably higher than in the northern hemisphere it would be fair to say that printed ABS is up to the job. I will try to post pictures later.

Thanks for the information Alan.. just the sort of thing we need to know.

Okay a couple of pictures, first is the sleepers, second is my print center, 3 printers all of the 3D up variety I have tried and discarded all the cheep varieties they simply can't produce the quality print I can get from these printers

Mmmm - I wonder if they will have them over here. I have seen them online at Rapid - I suppose you just need a steady hand!
