nod Posted March 20, 2018 Share Posted March 20, 2018 Oooom marvelous technology They even have driverless Taxis in the US Totally safe Link to comment Share on other sites More sharing options...
newhome Posted March 20, 2018 Author Share Posted March 20, 2018 It was @SteamyTea who said more should be constructed off site. Well this is press a button on site and watch! Wonder if they get the equivalent of paper jams ...... Link to comment Share on other sites More sharing options...

Hecateh Posted March 20, 2018 Share Posted March 20, 2018 I think there are already using it for prosthetics in medicine, though - as yet only in a few cases. Lots of research going on. 1 Link to comment Share on other sites More sharing options...
SteamyTea Posted March 20, 2018 Share Posted March 20, 2018 I read a report on that 3D printed 'charity' house. It is only the shell. The rest is manually fitted, including the roof. I was involved with emergency housing in the early 1980's. We made a dome mould and the 'house' got sprayed up with PU foam, so just like a hot water cylinder. Was a step up from a tent, but was just emergency shelter, not long term housing. Though I do think there is merit in the techniques used. There is no reason, apart from finance, not to have automated house building. They are not complicated really, though people like to think they are. Now where is @StructuralEngineer as he has been working on this sort of thing. Link to comment Share on other sites More sharing options...
Hecateh Posted March 20, 2018 Share Posted March 20, 2018 Still got some of the 10 year prefabs built in the 40s/50s local to me.And they are still very popular Link to comment Share on other sites More sharing options...
Temp Posted March 20, 2018 Share Posted March 20, 2018 I always thought 3D printed objects were fragile but someone told me recently that they are now 3D printing parts for direct use on F1 cars. Link to comment Share on other sites More sharing options...
SteamyTea Posted March 20, 2018 Share Posted March 20, 2018 There are many different types of 3D printing. Metal laser sintering can give very impressive results and different characteristics than cast or forged parts. Link to comment Share on other sites More sharing options...
StructuralEngineer Posted March 21, 2018 Share Posted March 21, 2018 Thanks for the link @newhome. This looks like a more sensible "test case" for 3D printing concrete than I have seen in the past -- i.e. with several human interventions such as lintels over windows -- and sticking to vertical walls only. I wonder whether this is any use though? If the lack of strength in concrete without reinforcement means you can only print vertical walls, it takes the whole point out of 3D printing, which is that you can print forms you wouldn't usually be able to create easily. Speed of construction is slow - you have to wait for each layer to set, and the footprint is small because it's confined to the size of the print bed.

SteamyTea Posted March 21, 2018 Share Posted March 21, 2018 It seems to me that it is only the dreamers that think that 3D printing is the way forwards for the mass market products. Generally it is very, very slow, limited in size, limited in material choice and expensive. If you take emergency housing, one thing that is not lacking is labour. An old mate of mine works for an NGO that deals with the second response to an emergency (Shelterbox). Part of his job is to show people how to make a working camp (not as simple as just putting up a tent). They looked at temporary housing that was manufactured off site but think they dropped the idea in the end. My personal view it that with sheets of ply, 6" by 3" timber, some rendering, windows and doors made off site, an adequate temporary house could be erected quickly and cheaply. One thing that is easy to forget is that other parts of the world have very different building standards (earthquakes and floods) and what we build in the UK is just not suitable.

SteamyTea Posted March 21, 2018 Share Posted March 21, 2018 My bones feel as heavy as concrete and my tendons are more ridged than sintered titanium today. But I have a new water cylinder in and have managed to have a shower. Bet my cute neighbour is relieved. Link to comment Share on other sites More sharing options...

SteamyTea Posted March 21, 2018 Share Posted March 21, 2018 Not asked her how she is getting on with it since she has got back. Seems like an excuse to go around 1 Link to comment Share on other sites More sharing options...

They are indeed, in fact the ex-US Ranger bomb disposal guy who is driving much of it (started by printing new limbs for himself) is the best buddy of one of my very good friends. 1 Link to comment Share on other sites More sharing options...
