3D Concrete Printing Technology in Construction

MudBots has tested, and continues to test, a myriad of different mixes from standard Portland scenarios to hempcrete, clay, polyethylene, polyurethane, geopolymer and geopolycrete. While most have never heard of some of these mix solutions, they are on their way to becoming industry standards in the not so distant future. MudBots has spent most of their time printing with nothing more than standard Type S Mortar mix. The strength of Type S is about 2500 to 3000 psi which is more than enough for print jobs, but when you begin adding other attributes like hardeners, synthetic fibers, polystyrene fillers, powder adhesives, plasticizers and dies, you can significantly change the mix's characteristics.

How 3DCP Works

MudBots provide the best solutions, after-service trainings, and technical support on 3D Concrete Printers.
Find out how it works.

Concrete printing is possible with the construction of a large 3D printer capable of printing large scale structures, from spas and barbeques to homes and larger commercial buildings, without the need of traditional framing, forming or blocks. MudBots offers printers from 10' x 10' up to 100' x 100'.

Affordable and readily available oncrete printing mixes

There are hundreds of different mix formulas that closely resemble a mortar type mix. Each mix requires months of testing for different characteristics, such as fluidity, bonding, water impenetrability, Seismic resistance, as well as curing and strength. Mixes are designed for 1200 PSI up to 10,000 PSI, depending on the structure and engineered objectives.

2D Drawing and 3D Drawing designs and watch it get 3d printed in reality

First step is to decide what you want to print.

The next step is to conceptualize a 2D design using a CAD program, and then converting the design to a 3D model using any 3D software that can export an STL file.

It is important to have a design ready and make solid plans before you starting dabbling on 3D Concrete Printing

Once the 3D model is ready, the STL file is imported into a slicing software, where the height of each printed pass is specified.

After slicing the model into individual print passes, the system exports the code which is interpreted into actual nozzle movement.

The mix is batched on site after which, the liquid ingredients are added to the dry mixes and mixed for delivery to a computer-controlled pump, which works in unison with the printer to control nozzle speed, and the volume rate of material at the nozzle.
