The exterior wall is now complete and I have started printing the footbridge. This will be made from 150mm long modules and be 80mm wide. The first island piers have been printed and are a scale 7'6" high making the deck of the bridge 15' above platform level. I will probably design and print a set of smoke deflectors for each of the three tracks it has to span.

Progress is typically 15mins for a bracket and 75mins for a support border lattice. Printing it may not be fast but it is better than I could do!!!

Does anyone have experience of using printed buildings etc in the garden, and how well they cope without getting brittle in cold weather for instance?  Another matter is how to get paint to stick and stay stuck.

Tim,

I have a feeling that I am the only person here -so the answer will have to be "I will let you now in a few years time". I have a sheet printed PLA that you can experiment on -but I plan to use standard grey car primer on the PLA and then use polyureathane varnish on the wood work before I spray it grey. I only worry about wind damage and (now) the amount of snow the bridge will take...

Ralph,
Think about using Halfords car bumper primer which is quite popular I understand for plastic items outdoors. I assume it must have an etch role.  Good luck in this trail-blazing approach!

I have used "Plastikote" grey super primer on polyurethane resin castings, overpainted with Humbrol and Tamiya acrylics.
They have been outside for three Summers and Winters and are showing no sign of flaking. Biggest problem with plastics outdoors is expansion and contraction if exposed to extremes of temperature....joints tend to open up or compress and that can cause problems if fixed to a base board.
Long runs of platform are particularly susceptible and the high coefficient of expansion means it is almost impossible to prevent unless the cast objects are left free to move.

Regards,
John.

Like every material PLA is bio degradable but in what timescales is the question.  People have left PLA 3d printed parts out for a year in the californion sun with no bad effects other than some colour bleaching. Others have buried parts in a compost bin for a year again with no side affects.

So well painted outside should not be a problem.

ASA (UV resistant ABS) would be better but gives of toxic fumes when printing.  PETG is even better but hard to print with.

As this is my first time with a RepRap I took the advice of an American friend and used PLA. It is supposed to be easy to print and I have to admit that it is!!! I am not overly concerned about detail , I am just printing bricks and steel girderwork. The second stage pier to the bridge should be complete by this evening and the other second stage pier by the weekend.

The bridge is a generic MR design and is a standard Warren Truss configuration. This means it would have taken the span of 45' and foottraffic with ease. There are the usual braces and cross beams. This is a functional piece not stylised as some of them that I have seen!!!

According to the smart meter The electricity consumed over the 44hr 56mins to print all this was 3.16kWh...

Tim gave me a dead line to make it all look like a station. I think I will make it!

well after 3 rolls (or 3kg) of PLA filament later we have this! The bridge spans three tracks and is 15 feet (scale) above the platform. The frontage is complete bar final assembly. The final part is primer and paint.

PS sorry about the mess -but this is what we call the family room. Here you may play music and strum to your hearts content!!!

The station is finished, so before I plonk on the roof, here is what it looks like. I would suggest that before anyone else travels this route that they sit down and work out how many and types of module they are going to need. In the end I needed more bracket types than girder types. PLA has proved to be very easy to print with (thank you Thomas!) and eBay has provided cheap filament. Since I was going to prime and paint it I could buy the "unfashionable" and simply vile colours that no one else wanted to buy.

I was going to bring it to the AGM -but the table space precludes that. So, I am going to see if I can squeeze the bridge in the space allotted to the East Midlands Group. I have given it a "once over" with a can of red oxide -but the original PLA colours still show through(!)

Rather than sit and huddle by the stove I have set the RepRap in motion again, THEN gone and huddled by the stone!!! I am printing Building ][ which was the shed for "The Twins". These I have inherited from the late Dave Lowe..

All the modules that are used to print it may be found in the G3 wiki. I suppose I should produce a directory of shapes for it?

Dear Ralph,

I take my hat off to you! The Rep-Rap machine you have bought for yourself is really bringing models to life - particularly suited I think to printing model buildings.

For your sheer persistence in proving what can be done with Rep-Rap and your comfort in sharing your work is truly inspirational. Many thanks for all you have done to improve my understanding of the hobby.

Excellent work!  8) 8) 8) 8) 8)

Robert, I am embarrassed... It was you who sent me the picture of LMS 10,000 emerging from Building ][. You also sent me a rendering of the loco in "Royal Scot" livery. It males them look drop dead gorgeous!!! In my heart I know they should be black with silver. But when I look at the picture I go "OH WOW" in my head.

I exhibited the station and bridge at the AGM yesterday. I think I shocked a lot of people. Not with the actual buildings but how cheap they were to make. I turned down several approaches for commissions.

So, here are a few figures:

Prusa i3 Reprap £107
1.75mm PLA £11 each I used two and a bit so call it £25.

All the scripts for the Lms Lego parts can be found on the G3wiki. Happy printing!

Two days of sticky work I have one curtain wall of four and a partially built window wall, also one of four. The machine is hard at work and I can use three days of production on one curtain wall...

Ralph

I'm guessing you were positioned at the top of the steps on the stage (not the best position?) - saw them from afar but apologies for not stopping for a closer look.

Every time I passed by, I was on my way to something 'very important' - you know, like when you climb the stairs at home & by the time you get to top you've forgotten what you'd gone upstairs for.

I very much liked your foot bridge Ralph - a complex structure that would be time consuming & difficult to construct using other means. I was also surprised at your estimated cost of the materials consumed (which was much lower than I had expected).

Ralph,
Anne and I thought your station and footbridge were Brilliant, Well Done!

I took some video of them, but as you know, the lighting wasn't up to much; I will see if any clips are suitable for our 'TeamPIRATE' You Tube channel.

As to being at the top of the stairs - believe me by mid day I really knew it!!! They got steeper as the day went on. By the look of the grand son of the person with you IanT I can see that he would grab a Reprap...

this is a completed curtain wall and window wall.

One side wall is now complete. It will require a little addition of glass fibre putty to fully strengthen it. But I can hold one end and the other end doesn't fall off!

Well the printer has kept going and I now have two wall curtains and half a roof. Structurally speaking it is very strong but not very water tight!!! At 1.2m long -it will be a suitable home for "the twins" or a couple of Peaks...

It is not going anywhere else but outside so your only chance to see it is here!!!

Its quite scary just how little power the 3d printers take, to run one for 24 hours costs around 4 pence.

While not exactly a building... These are the latest things to come off the printer.

An engine mount: and a boiler ring the door will be printed later. As usual all the files will placed in the Wiki.
