3 D Printing 16mm models

...... - is that the new printer Rik?

Hi Trevor
Yes. The body was done on the new printer and the chassis on the old one. I'm trying something called 'ironing' in Cura which is supposed to give a smooth final layer. The van was done before I started playing with ironing. I'm not sure I've got the settings right for ironing as the finish is sometimes worse than without it.

I always leave 'ironing' on and I think it does give a better finish where there are largish flat top surfaces, but if the top is a small area it doesn't seem to be noticeable. It doesn't do anything for angles or vertical surfaces, or for intermediate flat areas. I've been playing with an open wagon body recently but even with ironing on, the wagon floor is still showing print striations.
As I'm sure you know, it works by running a second pass over the final layer with the nozzle heat on but no filament being ejected. This just lightly re-fuses the final layer and evens out the striations. I think it works best with an increased number of top layers and/or higher infill %. If the number of layers is low then some of the heat of that ironing pass gets to heat up the trapped air inside and with the surface hot, 'pillowing' occurs.

I am making good progress with the station building. The roof panels are printing well so far. The triangular profile of the lower edge of the slates is (as far as I can tell from photos) pretty close to the shape of the original slates.

So three views of the roof so far:

There will be ridge tiles to go over the ridges of the roof - so I am ignoring the slight gaps along the ridge.

I am particularly pleased with the roof on the porch.

An FR-ish Tipper because I drew it up from photos not actual drawings and I know some bits aren't quite right.
However, first the kit of 3D printed parts:

That is VERY nice!

Cheers Trevor.
I'm not very happy with the body, tbh. I tried to be too clever by slowing down the print speed AND increasing the minimum layer time, and ended up making the striation effect worse! Still I know what to do ( NOT to do) next time.

[Trevor Thompson]

The station roof is still printing.

Another 6 panels printed and the second roof glued into position:

I have also started to add the stonework details to the chimney using a Bromley Crafts mylar template and wall tile adhesive. I have added black acrylic paint to the adhesive to make ir a dark gray:

And the last roof is printing out - in 4 sections.

I am starting to think about ridge tiles and window frames.

Well that looks pretty darned good to me......

Those roof tiles look the biz! This is the sort of thing that 3D printers do well, which would be tricky to do otherwise

There's some very impressive work going on here. Love the chimney stack and accurately-shaped tiles on the station building, and the tipper really captures the (pleasingly quirky) look of the real thing.

Nice that they're on the same thread too - the tippers are currently at Beamish, I believe, but I wonder how many times they'd have trundled past that station building "back in the day"?

My latest effort....

Drawn in TinkerCAD and printed off.

Terrific looking van Rik - and the finish is impressive!

Wonderful model Philip - like the details; very crisp.

This is really starting to take shape - can't wait to see it finished and in position!

Now that is very, very impressive. I wish I had looked at the thread before all of this goings on with the forum...
I haven't been, well I have, interested in 3D printing because it looked to hard to do, but having recently had a member make me a kit to build and looked at the excellent quality of the parts, I am now seriously considering buying a 3D printer even if it means going into debt , an £80 printer is still more than I can afford and cheaper than that haven't had very good reviews.

Also I am still not sure what programs would work with my MacBook Pro. I know members who are into 3D printing have said that they alter the programs to try and get some better results and they have been successful in doing so.

Your station however looks just like a kit that the so-called professionals sell, but even better. I very well thought build of I am sure will be one of the best stations to be seen.

Now that I have found and started to read this thread, I will start from the beginning. Philliply's wagon looks just as impressive by the way and made without any plans is even more impressive.

[Trevor Thompson]

I also like the fact that Rik and Philip in particular are adding to this thread.

When I started it I commented that I couldn’t find anything on 3 d printing. I can now as I follow particular authors threads. As an example I found Riks thread on the Bone works and the 3 d printed window frames and beam engine.

I hope that what we are doing here makes it easy for others to find!

Phillip in particular is very accomplished at 3d printing, as is Rik's. But you take yours to a different level Trevor.. Though everyone who do make 3D models are very good and it does inspire me to look into for information on printers and how easy they could be for me to try my hand at it. I did look and download the Fusion 360 program, but wow, what a lot of for me, confusing things you need to know.


I won't bore you with my explanation and wouldn't know were to start.....

Try Tinkercad, it is literally child's play as that is what it was designed for. Clearly at my zero cad experience level, it's perfect for me, I am getting on well with it, as is Rik. Some of the things we have designed in there are quite complex now we look back at them.

[Trevor Thompson]

I would second all of that.

I am convinced that the 3 D printer is a valuable part of our hobby, and its value does depend on being able to design your own creations.

Tinkercad gets you started, and can take you quite a way - so what is to dislike?

Fusion and sketch can be challenging to get into and having succeeded with Tinkercad then perhaps you will eventually have the desire to work your way into it. Or perhaps by then something else will have taken over.

And the printer? It is more important to get a start - and if its an £80 printer well so be it. My wife suggested this morning that I would be wanting another bigger printer for Christmas - and well I think Im doing OK with what Ive got - so the answer was no not really- I seem to be managing with this one!

The station building is now complete apart from painting.

The roof is on the ridge tiles glued in place and the window frames printed. Oh and that chimney pot looks a bit tall but I think it isn't so different from the real thing:

The windows are just pressed into place at the moment.The windows have recesses built into the back of them so that I can insert pieces of glazing material. But paint first.

So what next?

Let me take you back to the photos in the 16mm association Ffestiniog booklet, and in the Spooner Album as well. They all have pictures of Tan - y - Bwlch station with a horse drawn vehicle in front of the station building. As far as I can work out it belonged to the Oakley Arms Hotel and was there to meet the trains. Its the local bus!

I think it is a "Wagonnette". Which is an open private bus to seat 6 passengers in the back. This is my attempt at a wagonette:

The horse is from Thingverse, but the carriage is my own creation.

So lets try to print it!

That looks fantastic, Trevor. I really admire your SketchUp skills, having been there, tried it and given up.
