About this file
The document is a Salient Characteristics file for a Robotic Arm 3-D Printer, outlining detailed technical specifications for a mobile concrete printing system. Key requirements include a non-gantry mobile platform capable of printing cementitious materials with large aggregates up to 3/8" diameter, a minimum printing height of 20', a horizontal printing radius of 12', and a material output of 1 ft³/min. The system must be powered by a 60kW generator, operable without wireless capability, storable in a 20' shipping container, and transportable by a 12K telehandler.
Additional specifications mandate the printer to be operatable by no more than 3 personnel with minimal technical training, have a rotatable nozzle, weatherproof and corrosion-resistant components, and be NDAA compliant. The printer's slicing software must support .step and .stl file formats, with added value for compatibility with AutoCAD, SolidWorks, Revit, and other 3-D modeling software. The system must have a quick assembly time of under 1 hour, including calibration, and be designed for ease of use and mobility in construction environments.

Salient Characteristics for Robotic Arm 3-D Printer
• System will include mixing and pump systems for sending printable material to the printhead. Printable materials include cementitious materials, mortars, and concrete o Pump and mixing system must not require proprietary printing materials o System must support the printing of large aggregate up to 3/8” in diameter
• Non-Gantry mobile platform required.
o The system needs to be readily movable on a print site (e.g. track or rail system).
o System movement during printing does not require heavy equipment (e.g.
crane, telehandler)
• System must be able to print to a minimum height of 20’ (May be a combination of vertical reach and integrated adjustable vertical base)
• System must have a minimum horizontal printing radius of 12’ from a stationary printer base
• System will have a minimum material output of 1 ft3/min
• Rotatable nozzle
• System will include weatherproof and corrosion resistant coatings and connections
• The system must be able to be powered by a 60kW Advanced Medium Mobile Power
Sources (AMMPS generator)
• System will be operatable without wireless capability (Must be hardwired)
• System will be storable in a 20’ shipping container (including pump+mixer)
• All components will be transportable by a 12K telehandler for initial set-up
• Assembly and disassembly of the system shall take no longer than 1 hour o Assembly time includes printer calibration
• Printer operation will require no more than 3 personnel o Operation will require minimal technical knowledge of software/programming, and will only require introductory training for operation
• Printer slicing software will be able to develop print paths using .step and .stl file formats. Additional compatibility with other native file from formats from AutoCAD, SolidWorks, Revit, and other 3-D modeling software will add significant value.
• System will be NDAA Compliant
