3D printed concrete

[GAP]

When I visited the Railway Museum at York there was a display showing the the railways in the UK are using 3D printed concrete.
I thought that was interesting and wondered how big the printer must be to do this.
Saw this on the net so decided to share.

There must be some sort of support in there somewhere, surely

There is a lot of info here, looks like there are various processes, pick one that is suitable and make your mark....

Coming to a housing estate near you, been on the go for a little while now but I do wonder about it. I would have thought a wider gap for insulation might be useful no doubt UK building companies will get into it once the profitability is proven compared to traditional build and the planning gets on board, that will be the tricky one. No doubt the next compensation disaster when the buildings start to break up after 10-15 years.

If thats a track base for a indoor gscale railway. I think those curves might be more than R1 ! hee hee eheee

If any of you are thinking of trying this at home, I think you are going to need a bigger shed.

It must be economical and the planning people must approve because the display said that the Railway people were already using it.
It was the use of concrete in this way, the solar panel innovation for their overhead structures and the use of recycled plastic as sleepers which attracted me.
A new era in construction methods and materials usage has possibly begun.

There was quite a well known house in Royston made wholly from concrete, it looked good, but apparently the condensation was terrible and it suffered hugely from damp and mildew. I assume this wouldn't be an issue with the new methods

Be interesting to see how it pans out, planning in Uk though is extremely tortuous even though methods have been used in the past. As for the damp, yes I could see this as being a possible issue if the cement remains cool and the house warm. Perhaps insulation on the i side walls may help, though I see the concrete being a good plan for warm climates. A thing I got involved with helping a chum with some work on a house in France was what he called ‘lightweight concrete’ this consisted of a mix that incorporated a high percentage of expanded polystyrene granuals. Think the stuff that breaks offf when you cut it, the individual bits. Whilst used for a floor on top of wood floor it made a good surface for tiling with good insulation properties. I could imagine this to be on the inside of a 3d printed house, itself with the lightweight stuff printed in place being a good possibility.

Down here they use polystyrene inside the concrete slabs they lay to keep the floor cool.
For insulation expanding foam can be used , similar stuff to what is used in packaging, and to to fill gaps in things. I use a version that filled gaps around window frames in a brick house it was weatherproof and paintable.

I personally prefer Wattle and daub as a building material...... its hard to 3d print this I'm told and AI doesnt know how to classify it,.... As a disclaimer I live in a 60s ugly bunglow which i love and love cocreate too as a base for my wooden sheds !

BBC Two - The Mayfair Hotel MegabuildDid anyone see the repeat/additional showing of Mayfair hotel mega build.... The concrete roof windows were all precast and build in northern Ireland and shipped to london and looked amazing, the guy who won the contract had to learn new "old" skills to do it.

I lived in a house whose walls and floor were precast in the UK and shipped to Australia (was what married members were given by the RAAF).
It was part of a UK government scheme to provide work for people after WW2.
The floor didn't butt up against the walls and we had grass growing up into the kitchen cupboards.

Parts not joining in Oz with lots of insects and other things that would like to eat or poison you sounds really scary, something to look forward to (NOT) in uk with global warming.
