The FieldPrint Platform moves the coordinated VDC model from the design environment directly onto the jobsite floor. The FieldPrinter 2 (FP2) is the autonomous layout robot at the center of that platform: it prints the model at full 1:1 scale on the slab at 1/16" accuracy, run by a single operator. This document is the technical specification for FP2 and the surrounding platform components (Laser Tracker, Dusty Portal, Revit/AutoCAD plugins, Dusty iPad App, and the Floor Elevation capability).

Notes
Format
Inkjet cartridges (one per print head)
Automatic detection of ink type and color.
Cartridge yield
~15,000-18,000 linear feet of solid line at 1/16" line width
Volume per cartridge
~41 ml
Water-based colors
Black, red, blue
Ship in the standard kit. Best in warm conditions.
Solvent-based
Black
Shipping restrictions apply. Best in cold conditions and on slightly moist concrete; high permanence.
Permanence
Surface-, ink-, and UV-dependent
Standard water-based typically lasts 2+ months. Clear coat improves water-based permanence in high-traffic/UV areas. Always test on the specific surface.
Floor Elevation (Open Beta)
Floor Elevation extends FP2 into the Z-dimension, measuring floor height deviations using the same control points and Laser Tracker setup as layout printing - captured while the robot drives or prints. No additional hardware is required. It requires the tracker to be leveled to a stricter tolerance than standard printing (a levelness check is performed during stationing).

Platform software
Dusty Portal (GA)
Web-based coordination and reporting hub. Accepts Dusty (.dusty), AutoCAD (.dwg), Revit (.rvt), and CSV point files; normalizes all inputs to one coordinate system; aggregates them into a single "Ready to Print" file. Provides layer control (visibility, role, line style, line width, text/point height, trade), a live print preview, and bidirectional production reporting by day, trade, and layer with cost attribution.
Revit & AutoCAD plugins
Prepare robot-ready layout files in the design environment and upload directly to Portal. Export to AutoCAD Dusty (.dusty) format. Both require a Dusty Portal account.
