Construction technology 3D printer
COBOD BOD2 3D construction printer
The heart of our holistic 3D printing solution is the COBOD BOD2 construction printer. The modular gantry printer is quickly set up around the printing area and moves its print head on three axes to pull up the walls of the buildings. Once calibrated, the BOD2 prints one square meter of cavity wall in just five minutes. The modular configurability gives you flexibility in every project and you can easily expand your printer for larger projects. The COBOD BOD2 3D printer can be purchased or rented through us. We also offer comprehensive training on the machine as well as support in the planning and approval processes.
Technical specification
Printer and building sizes
Maximum dimensions of buildings: 13.5 m (44.3 ft) wide, 9 m (29.5 ft) high and as long as desired.
Example sizes of printable buildings:
-
3D construction printer in our rental park: building with a maximum floor area of 204 sqm (2,195.8 sqft) and 3 floors.
-
Largest printer built so far: building with a floor area of 300 sqm (3,229.2 sqft) and 3 floors.
Assembly and mounting
-
Set-up and dismantling times depend on the configuration of the printer. For a machine with a printing area of 13.5 m (44.3 ft) width, 17 m (55.8 ft)length and 8 m (26.3 ft) height, 8 hours are required in each case.
-
The BOD2 is bolted either to the floor slab or to concrete blocks.
Print speed
-
The maximum speed is 1 meter/second (3.3 ft/s)
-
For safety reasons and in order to be able to continue to integrate manual work into the printing process, we print houses at 25 cm/s (9.8 inch/s). Therefore, for 1 sqm (10.8 sqft) hollow wall, the BOD2 needs approx. 5 minutes.
Safety technology
Technology to ensure safe machine operations:
-
CE-certified and safe
-
IP67-certified cabling and galvanized steel trays
-
Camera monitoring of the printing process and results
Print material
Any locally available 3D printable mortar or concrete (up to 10 mm/ 0.4 inch grain size) are usable. So no special 3D printable materials that could only be obtained from us are needed.
Layer height and width
Flexibility in hight and width
-
Layer heights between 1 and 4 cm (0.4 - 1.5 inch)
-
Layer widths between 3 and 10 cm (1.2 - 3.9 inch)
Tangential control
Allows very smooth surfaces to be printed - if this is desired. Rough surfaces as a style element or for easier plastering are also possible.
Data formats for slicer-software
The software can read all formats of traditional CAD-software; i.e. the data formats .STP, .IGS, .BREP as well as .OCC are supported.
As a shareholder we are partner of COBOD International A/S Denmark, who developed and produce the BOD2 technology.
