Frequently Asked Questions


What is 3D Printing?

3D printing is the process of creating a three dimensional physical object from a digital design, typically from layering many thin layers on top of each other. The usage of 3D printing is growing and it is currently being used in the following sectors: aerospace, medical, automotive and construction.

What does Cazza do?

Cazza provides 3D printing construction technology and services. We sell 3D printing technology that can be used to build a wide variety of buildings and structures. We also provide design, engineering and construction services to help you build your 3D printed dream home.

What Can Be Printed With Cazza’s Technologies?

The Cazza X1 robot can build two to three story buildings and structures. This includes: houses, villas, mansions, cottages, commercial buildings, offices and free standing structures. Currently, if you can think it under 9m tall, it can be built.

What are the benefits of 3D printing?

3D printing is more cost effective, efficient and safer then traditional methods.

  • Cost effective: Material and labor cost savings, are up to 37% lower than using traditional methods. Projects use less materials and may have half as many personnel required to build a structure.
  • Safer: 3D printing construction reduces the number of workers on site. Not only does this reduce the cost of labor and labor related costs, but it also reduces the number of workplace accidents.
  • Efficient: In comparison to traditional methods, 3D printing is up to 76% quicker. Robots don’t need breaks and can work on average faster than the average person.
  • Error Reduction: 3D printers are reliable and reduce the potential for human error.
  • Environmentally friendly: Up to 55% less concrete usage in 3D printing for structure construction. 3D printing construction also reduces construction waste on site.

Are 3D printed structures safe?

Yes they are!

Our structures are built mainly using concrete and are designed for maximum strength through topology optimization, which optimizes material layout within a given design space, for a given set of loads, boundary conditions and constraints.

Is my house built on site?

Yes! All structures are built on site using Cazza’s technology.

I want to build my home. How long will it take?

It depends! The size of what you want to build and the design will affect how quickly your home will be built. In general, 3D printed homes are built 20-76% quicker than traditionally built homes. This is dependent on how many 3D printed parts there are and the design of the structure. If you would like an assessment on your potential project, please check out our Projects Page and provide us with as many details as you can.

How fast does the machine print?

3D printing can be up to three times faster than traditional formwork. The Cazza X1 has an average speed of 400 meters per hour. This speed is highly dependant on the material used in the construction.

I want to build a home. How much will it cost?

It depends! The size of your home and the design will affect the cost. Cost is dependent on whether your home will be completely 3D printed or have a combination of 3D and traditional methods. If you would like an assessment on your potential project, please check out our project page and provide us with as many details as you can. On average, 3D printing is up to 37% cheaper than building by traditional methods.

How many stories can be printed?

With the Cazza X1, you can build stories up to 9m in length (typically two to three stories). Other robots that Cazza will release will be able to build structures higher than this. Please sign up for our Newsletter, to be informed as soon as these are released.

What materials do you use to print?

Cazza’s structures are printed from a special mix, primarily made of concrete.

Would the roof of my house be 3D printed?

It depends on the loaded weight on your roof. Roofs can be 3D printed depending on the loaded weight that will rest upon it. In the case that there will be a lot of weight, than traditional methods will be used.

Is the foundation 3D printed?

No. Foundation and excavation will be done by traditional methods. The formwork for the foundation can be 3D printed.

Are the electrical and plumbing 3D printed?

No. Electrical and plumbing are installed via traditional methods. Our special software will analyze where the electrical and plumbing will go in your structure and the robot will make pre-programmed pauses for both to be installed while printing is ongoing.

What other elements of my building will be done by traditional methods?

The following are not 3D printed: windows, doors, decorating and finishing.

How are reinforcements installed? Are they 3D printed?

Steel reinforcements are input manually by traditional methods. The 3D printer is programmed to pause for a worker to install them as printing is ongoing.

How is thermal and sound installation installed?

The structure can have hollow spaces which can be filled with acoustic and heat isolation foam after the printing process is completed.

How is the building site prepared?

The building site must be cleared of debris and people. While not necessary, it is helpful if the terrain is level. Depending on the climate conditions, additional labor might be required.

What is required on site for the printing process?

The robot requires both a power source and concrete supply to be able to build. The robot can be connected to an electrical source or use the generator that is on the robot for power. The robot is able to run approximately 48 hours continuously using the generator before needing to be refuelled with diesel fuel. Should you wish to print in the evening, lighting will need to be set up for workers to see the site after dark. Cazza’s 3D printers don’t need to take a break and can continuously print both day and night until a project is finished. Lastly, a concrete mixer and pump are required to connect the robot to the concrete supply.

How long will it take for the robot to be set up once it arrives on site?

It takes approximately 30 minutes for the robot to be set up to build once it arrives on site. The Cazza X1 is fully mobile and remotely operated, making it easy to move the machine from the transport truck, across the construction site to where the structure will be printed.

What happens when my structure is done printing?

Once your structure is done printing, the robot will self-clean and be ready for removal. Once cleaned, the concrete supply needs to be un-hooked, then the robot can be move manually or be remotely operated to board the truck for removal. This process takes about 30 minutes.

How is the robot programmed?

Cazza files are transfer either wirelessly or by USB cables. Our special software will run an analysis of the file prior to printing and determine the dimensions of what areas needs to be 3D printed prior to printing.

What files can Cazza’s robots read?

The following formats can be transferred into our 3D programming software: 3Dmax files and CAD (this includes STL and AMF files which can be created using almost any 3D CAD package).

How many workers are needed on site during the printing process?

Generally, only three workers are required on-site during the build process. One for control of the robot, one for the concrete supply and one for general labor, such as installation of the plumbing, wiring and reinforcements.

How is the printing mix supplied?

Once the order is made to a local supplier, it is delivered and loaded into the robot via the concrete mixer.

In what climate conditions can the robot operate?

Cazza robots can operate in any environment. However, to maintain the concrete mix in rain or snow, the construction area must be covered so that the mix can harden properly.

How long does it take for the structure to dry?

Cazza’s build mixture dries and hardens rapidly as the robot is printing. The structure will be hardened and dry before the robot circles around to layer another layer.

Do Cazza’s structures comply with regulations?

Yes, we comply with both US and EU construction regulations.

How durable is the equipment?

The robot assembly is set for 10,000 hours, before any preventive maintenance is required

What is the printing accuracy?

The robot has a printing accuracy of ±0.1 mm spherically.

How thick can the walls of my structure be?

The walls of any structure being built using Cazza’s X1 printer can be up to 10cm in thickness.

What happens if the machine breaks? Can I return it?

In the unlikely that a Cazza machine will malfunction, but in the case that it does, please contact us immediately. Cazza will provide machine maintenance and fix any robots under warranty for up to two years free of charge. Once a robot has passed it’s warranty, then applicable changes will apply.
