The name of this type of machine is called a 3D house printer. It is going to be the first 3D house printer to be built in Nigeria..
The 3D printer machine will be capable of building a family sized bungalow in a single day, starting from german floor level to roofing level without the direct involvement of human labour ...
The isn't to build an entire house without the involvement of human labour, it would just do the laying of bricks using motar to hold them, just like the conventional way used by bricklayers to lay bricks..
Here's how it would operate in real life; the foundation would be dug by human labour and the necessary blocks placed in place,then the floor casted. The machine would then start operation from here, which is the casted floor. It would lay each block one at a time whilst squirting concret at the right places. It will do this operation all round, untill a 1st couche has been established. It then move up a bit, return to the starting point and repeat the sequence again. It does this untill it gets to the roofing height level. At this level, it will stop the operation. Human labour would then take up from there, doing the necessary fittings, plumbings, wirings and roofings etc.

Suffice to say that, this 3D machine would yield nice bussiness prospects.
Seeing as Nigeria is a developing country, houses are being built everyday but manually by hand, not to consider the time it takes to erect a single house... It wouldn't be a bad idea to have a machine do that.
The advantages sticks out like a boil.
It would cause an amazing reduction in the capital needed to build a house by 30% to 40%. Which will allow those with a very low income to own a house.
The little time its going to take to erect a building, will be promising in areas with a natural disaster, because it wouldnt take long to put up large number of buildings to shelter displaced persons.
it will also create direct employment in the area of building a plant to mass produce the machine.
It has been estimated that the exact amount needed to build this huge machine, up to a working prototype is $5000 (1 million naira).
The technical details and its operation is elaborately explained in the link below, sponsors are being sought for as well.

The pix below is how the machine will look like.

To build a house, the 3D printer uses only Bricks and mortar (mixture of cement, sand and water).

There has been talks concerning the time frame that would be spent in building the first 3D house printer prototype.
The drift is; the nine months i stipulated to be the time that would take to build the 3D printer might be seen as too long a time. This is because in every first prototype of a specific model of 3D printers, they will pass a rigorous scrutiny of numerous calibrations, because they are going to be the yard stick for subsequent mass production of the model.
So after this first prototype is built, it will only take two and half months to build one, if i were to be working with one assistant.
If i were to be working with two assistants, it will only take one and half months to build one 3D house printer.
Hope you now get the drift?

Still no one

You can't expect people to invest in something you haven't even bothered to put any effort in.
You just copy-pasted an image from somewhere, no page no nothing, and all of a sudden expecting money to just be thrown at you.

Na so e easy to do 419?
Even 419 no dey possible these days without pre-game work.
