Gantry · Large format
WEAVER – G3
Built for large-scale construction such as buildings, warehouses and infrastructure elements. The largest printer in the world for on-site printing, suitable for G+3 building construction.
Construction
3D Concrete Printers
WEAVER gantry and FALCON robotic printers, plus accessories and printable mixes.
Construction
Printing the future of construction.
MERLIN's 3D Construction Printing systems industrialise construction through automation, robotics and digital fabrication. They enable faster project execution, less material waste, design flexibility and scalable on-site or off-site construction. Built for infrastructure, housing, industrial structures and precast applications, MERLIN 3DCP platforms combine precision motion systems, intelligent material delivery and advanced print-control software for consistent, structurally reliable builds.
The lineup
Five printers. Built for the way you build.
Gantry and robotic platforms for on-site, off-site and precast construction.
Gantry · Small format
WEAVER – G1
Compact gantry system for on-site and off-site printing. Suitable for G+1 building construction.
Robotic · Mobile base
FALCON – MB
A robotic arm on a mobile platform for flexible construction — single-floor buildings, long walls, remote defence infrastructure, landscape and architectural features.
Robotic · Linear gantry
FALCON – LB
Hybrid system combining robotic articulation with linear-axis expansion. Prints multiple sections without stopping production — ideal for off-site and modular manufacturing.
Robotic · Pedestal
FALCON – PB
Fixed robotic 3DCP system for controlled production environments — precast components, modular construction and repetitive manufacturing with consistent quality.
Software
BAYA — Design. Check. Print.
The concrete 3D printing software that takes you from idea to machine program, for robotic and gantry printers.
Design or import a structure, check that it can be printed, watch the machine do it, and export the program for your robot or gantry. Layer time, cold joints, bead size, reach, axis limits, scaffolding and large structures are part of the tool — not an afterthought.
- Design your own shapes, or import 3D models (STL, STEP) and G-code
- Draw plans with walls, doors, windows and columns; DXF import and export
- Check reach, axis limits and layer time before you print
- Simulate the robot or gantry, with fresh concrete highlighted
- Split big structures into sections with assembly sheets
20Robot models with detailed 3D
6Robot axes checked on every point
1000xMaximum simulation speed
2Printer types: robotic and gantry
Fewer surprises
Reach and axis limits are checked on every point before export.
Better bonding
Layer time warns of cold-joint risk before you print.
Fewer collisions
Gantry travel is routed round scaffolding; the G-code carries it.
Less manual work
Big structures are split into sections, with assembly sheets.
Staged prints
Export by height range and carry on where you left off.
