    Hello
    I would like to make Gantry concrete 3D printer to make houses.Please suggest me how can I make it? I am an architect, not from engineering background. I work in CAD softwares, I have concrete mix design to produce 3D printed houses. Many companies are doing it. Want to ask you can I do it myself if I spend some time? How complicated is it to assemble parts (make concrete printer)? i live in Estonia. where I can find parts? Please suggest me.
    Thanks

    Hello Ahishek,

    I'm new to the CNC world but not new to building houses and it is possible to make one (there are examples on YouTube).

    If you have ever moved a wheelbarrow of wet mortar then you know how heavy it is. You would need some heavy duty motors, big steel gantries, some sort of silo to feed the cement in from (consistency of the cement would be critical) and an ability spray the cement to bond each layer and it would be pretty difficult to setup on your own - you aren't going to find the materials to do this in the OpenBuilds part store.

    Cheers

    Adam

    PS When I was doing my apprenticeship I would have loved a great big tent to be setup around the house to keep me dry!

    I have to chuckle here. You are asking a question of immense scale on what is essentially a hobbyist CNC site. What you are trying to do is something that would take a large team, with a lot of resources, material and financial. Those Nema 34's are not going to cut it :)

    You would need to use steel i-beams or something similar to make up the gantry.. maybe repurpose a gantry crane system, replace the pulley system with a concrete extruding system...

    Something like this
    I know the cement mortar mix design, I also know 3d modeling in CAD software’s. Can you suggest me frown where I can buy parts of contact company in Europe. Which company makes these parts? I want to make this.

    The steel columns and beams in your picture can be purchased from any steel fabricator there is nothing special about them. The same is true of the concrete pump/mixer - any concrete supplier would have some or know where to buy one.

    The control unit and motors (possibly hydraulics on the Z axis but I can't tell from your picture) as @ljvb said probably came off a small gantry crane system. I suspect the problem is the printer head and nozzle will be proprietary and you will have to design and manufacture it yourself.

    The picture that @joe williams posted with the central crane system is clever as you don't need the large beams for your x and y axis and the associated setup time and you could just use a another crane to install and remove it from the centre of the house when it has finished printing.

    When you come up with a detailed design I would love to see it.

    Cheers

    I suspect that the majority of a system like this will be custom built...you'll have to spend some time on google to figure out what can be made from off the shelf parts and what will need to be fabricated by you. Have you tried to find an existing system that you can travel to and ask the builder these questions?

    Out of interest what is the concrete specification? It looks really stiff/fluffy in the photo you posted.

    Cheers
