Be coming soon.

The video was quite an interesting tutorial. I think mine is not an exception to plumbing.. But i figured a way to solve that problem long ago. In every site, the 3D would be erected and plumbed before beginning duty, that means all the blocks would automaticaly be plumbed.

Daniel2032:
Pls can I call you bro?

Offcourse you can Daniel. Two heads are definitely better than one. I appreciate your offers. Thanks.

kelvin1191:
Please remember that some blocks are hollow while others are full

Thanks, noted.

Here's the breakdown of the amounts and the materials that will be purchase:
350,000naira would be used to acquire 18pcs of small, medium and large stepper motors, 18pcs of stepper drivers, 6pcs of microcontrollers..
100,000naira would be used to buy an oxacetylene welder and a Tig welder machines.
50,000naira would be used to acquire a laptop for programing the machine.
Then 400,000naira would be use to buy the iron steels, e.g steel rails, steel girders, steel pipes of various sizes.
Then 100,000naira would be used for miscallaneous.

Ok Sirman. Thanks.

With 3D house printer in mind. I've taken my time to study bricklayers while they are on the job. I got to note the time it takes to lay a single block using concrete. The result seems to vary from individual to individual. I've measured anywhere from 4 minutes, 3 minutes to 2 minutes for a single block layed. And i consider this a huge waste of time considering ...
the amount of blocks needed to build a house.
What i am trying to convey here, is a way to reduce the time it takes to lay each block to a time frame of 6 or 7 seconds per block.

The relatively long time it takes to erect a building by manual labour is evident enough to indicate a huge waste in time.

The 3D machine would be a cool solution to that. Lets take an example where 500 blocks was to be layed a manual labour, at the rate of 3 minutes per block. Then it would take 25 hours to do just that.

With my 3D house printer, laying each block at the rate of 6 seconds per block, it would take just 25 minutes to lay 500 blocks with concrete. Nice time recovered.

The market opportunity for this project is so large, because houses are continually bein built all the time, irrespective of the location. The project touches almost every life that wants to build a house.

With the rates estates and houses are springing up here and there. When we're fully into the market, the demand will be so high that even with a hundred 3D machines at our disposals, there would still be alot of clients on the waiting list.

The current market cannot be described as stagnant, neither can it be described as dwindling. Building takes place every day, every hour, every minutes, probably all the time. We can capture a gread deal of the market with the reduced time frame of building a house and the reduced price as a dangling bait. The only barrier to that, is gaining access to the capital that will move this project off the blueprint stage and into a working prototype.

The only competitors in the market is the Southern Californian Professor Behrokh Khoshnevis, whose 3D machine is undergoing laboratory test, and the Chinese firm Winson that went commercial with there 3d house printer in 2014.

These aforementioned printers share one thing in common; they use fast drying concretes and dont use pre made blocks to print a house.. Some houses are cast as a single piece while some are built by laying blocks and using concrete to hold them..

There might arise the need to print a house using blocks and non fast-driying concrete. This is where Professor Behrokh and Winsun's machine would fail to deliver. And this is where where my 3D printer would come handy.

You dont gain everyones trust when you tell them that you are going to print a house for them, when they know you will be using fast drying concret's, and a contour crafting technology, because it's in its infancy. But you can some reasonable amount of trust when you tell them that you are going to print a house for them, and they happen to know that you will be using the the conventional and traditionaly tried and tested method; by using concrete to lay blocks one after the other.

In my humble opinion, i think these factors would allow us to gain sustain and grow in the market.

The ability of the 3D printer to grip blocks, cut them if necessary and place them in the desired position, would be what makes this machine unique compared to its competitors.

The product can be mass produce if deemed so, and sold to the public. Or it can be leased out to other construction companies and real estate developers. Or it can be solely handled by us. Which i think will entail us having different branches spread out around the globe. With the platform and structures in place, having spread our tentacles thus so far, with a little campaign on advertization through the media, the internet and printing ad, we would have secured a large proportion of the customers in the market.

stanvesco:
booking space..op u will hear from me.were are u based

Am based in Abia state, but i travelled to Abuja lately.

Ademat7:
I think u should approach AIT kaaki program to b specific,they will let the world knw abt u and also people will have confidence to invest in

Thanks for the info. Will look into it.

The next command would be to withdraw, and so on and so on.

Next command:

{8}Activate pump B.

This command will cause pump B to pump ont concrete so as to fille the gap. The gap is importatnt because it is the place where the concrete holds the two blocks toger.
The pix below shows the left pump B on, and the right pump A off.

Next command:

(7) Drop a block.

The pix below shows that.

Next command:

(6) Squirt cement @ length (100cm)

No need to explain what this command will do.
The pix below shows the smeared concrete, covering a length of 100cm.

Next command:

(5) Move x axis (+) @ (60)cm.

This command will shift the header 60cm in the x axis. In the pix below, the header has shifted to the right, at a length of 60cm. Since the length of the previous block is 50cm, there will be a gap of 10cm.

Next command:

(4) Withdraw headear.

This command will withdraw the arm. The pix below illustrate that.

The next command:


(2) cut block @ (50)cm

This command will cut the block at a length of 50cm.


Next command.

(3) Drop block.

This command will make an arm to grip the block inside the header, shoving it downward to come to rest on top of the smeared concrete. At the sides of the grips are two pumps,A and B. By the sides of both pumps are four rectangular plates called R plate. Two for each pump . Whenever any of these pumps are turned on, it is this plates that stops the concrete from running out of a gap.

The pix below shows the machine droping a block.

Command number one.


(1) Squirt cement @ length (50cm).

If i write only this command on the programe and click an option called 'convert'. The programme will convert the command into codes that are valid for an arduino. When these codes are uploaded into the arduino and a button pressed, the machine would squirt concrete on the floor at a length of 50cm. Just like the pix below. Note that: the bracked letters are the variables.

Now on to the programme.
..

This programme will take simple commands and convert it into codes that the arduino will understand, so it will be easier for me to tell the machine how to build the walls.

The programe will have a series of commands that can be called up.

The command below will be the first command i shall be starting with. Note: some of this commands have bracketed letters. The bracketed letters there mean that anything inside the brackets are variables. It means you will have to provide the information for the arduino to execute that command.

Now, to start the operation, the machine will begin at the pre default position. The pre default position is the position the header of the machine is brought to, at the beginning of a building. This position can be anywhere you choose to begin the building, as the instructor of the programme..

In the picture below, i am showing where the header will begin. This position is assumed to be my predefault position.

I have made the diagram in a graphsheet that is calibrated with vertical and horizontal lines, so i can representing each ten lines as 50cm for illustrative purposes.

Let me explaining the building process.

Lets take a look at the diagram below. It is the wall of a building, undergoing construction. The german floor is the slab underneath the blocks. Take note of the way the blocks are placed.
To have a machine that can be coded to build a wall, just like the wall in the above pix. And have it do it just exactly the same way the blocks are placed and the concrete holds them. The machine should be able to do the things i am going to explain and illustrate with some diagrams below.

arbitrage:
What is the business aim? To build more of it for sale or to use one or two to build houses for people?

The bussiness aim is to adopt that mode that will yield the most profit. If building more of it for sale will yield the most profit, then we do that. If using one or two to build houses for people will yield the most profit then we do that. But if both will yield profit, then we will adopt both method.
But in my own opinion, i do think building one or two or three, and using it to build for people will be most profitable.

arbitrage:
Can it be used to build a house and you remove it from one site to go and build in another site?

Offcourse. It can be dismantled, transported and erected in another site.

arbitrage:
Is the target to mass produce the machine from the prototype for people to buy and use or rather to make the prototype and be using it to build for people?

When i said mass produced, i wasnt meaning exactly that. I was just presenting a figure of the amount it would need.
The target was to build the prototype and use it to build houses for people.
