X3™ INDUSTRIAL 3D PRINTER
The X3 merges industrial quality and build volume into a benchtop form factor, bringing FFF composite 3D printing to your manufacturing floor.
The refined Industrial FFF 3D printer for micro carbon fiber filled nylon parts
Manufacturing-Grade FFF Printing
The X3 brings three versatile, advanced, micro carbon fiber filled nylon materials to a precision-built Fused Filament Fabrication (FFF) 3D printing platform, delivering functional part after functional part.
Wide Variety of Optimized Print Modes
Print in a wide variety of print modes all optimized to yield quality parts — including 50 μm resolution, which delivers ultra-high-quality parts without visible layer lines.
Industrial Reliability and Accuracy
Precision-machined hardware, advanced sensors, and unique software drive leading edge accuracy and reliability. Markforged industrial carbon fiber 3D printers offer micron-level laser scanning for closed-loop calibration, reliably yielding parts with high repeatability and near-perfect surface finish.

The Markforged X3 FFF 3D printer combines precision-built hardware, advanced sensors, and leading edge software to deliver accurate parts repeatably. It features a reinforced, precision-machined gantry and a precision ground print bed that can be removed and replaced with 10um repeatability. Each piece of hardware in the filament extrusion system — from the nozzles to the extruder hobs — is optimized to resist wear from micro carbon fiber filled nylon filaments and maintain print quality over thousands of hours. Out of material sensors ensure that you’re always printing while a scanning laser on the printhead enables the printer to dynamically adjust the first layers of a print to achieve ideal bed adhesion.
