3D Printed Wagons.

Post by David Girling » Fri Jul 10, 2020 5:00 pm

Hi everyone.

I have just been watching a piece of film on YouTube showing the building-up of a 5" Gauge GWR Shunters Wagon from a 3D printed kit by "3DPROLLINGSTOCK" and would like to know if anyone here has any experience of these kits, they seem to be very good value for what they are.
I realise that, being printed plastic, they wouldn't be to everyone's liking but they do appear to offer a cheaper and quicker way to build a rake of wagons, even if you replaced some of the plastic parts for conventional metal ones for strength/durability.

I look forward to hearing your opinions on them.

Best regards
David

How can I put this politely, you get what you pay for, and you wouldn't be paying much.
If you check our web site under the menu 'About', it says of locos "providing they are an accurate representation of a prototype, and conform to all GL5 standards". I suggest that the same applies to rolling stock.

I would like to see how the coupling hooks are attached and how/if the frame is reinforced.
They look a bit fragile.
There should be a continuous steel link from one coupling hook to the other, otherwise I would not dare to have them right behind the loco in a long freight train...

I bought one of the shunter's truck kits, mostly out of curiosity if I'm honest.
They're actually rather nicely thought out as kits and well finished, and ideal for those looking for a couple of things that look like wagons to trundle around their garden railway, and the chap making them is very approachable.

However they don't meet the requirements for scale, detail, accuracy or crucially robustness required by GL5, at least not without significant reworking, and I didn't buy it with this aim in mind. By the time you've paid the extra for buffers, axleboxes and axleguards, springs, couplings and wheelsets that I would consider the bare minimum for a properly functioning GL5- spec wagon then they wouldn't be much cheaper than some of the "traditional" kits anyway.

I do think there are some things that 3d printing could be very useful for, I feel it could better at representing cast or forged components than laser cuts for example, but I'm not convinced printing full wagons is the way forward for what we're aiming for (which isn't to say it's not ideal for others).

I agree with Matt that for some parts 3d printing is an alternative.
My PZ201 armoured railcar has lots of 3d printed (detail) parts but nothing that takes any load.
