VX7000 – The New Benchmark in Large-Format 3D Printing

With the VX7000, voxeljet introduces the next evolutionary stage of large-format binder jet 3D printing systems – engineered for industrial-scale operation and high-volume production environments.
Building on the proven VX4000, the industry’s long-standing reference model, the VX7000 sets new standards in precision, scalability, and efficiency.

Revolutionary Machine Concept

At the core of the VX7000 lies a kind of reversed build concept: instead of a descending build platform, the foundation of the printing process remains completely stationary. The recoater and printhead units move upwards layer by layer along a precisely guided Z-axis.
This design enables an extra-large build volume of up to 7 × 7 × 1 meters, handling over 60 tons of sand with uncompromising precision and surface quality.

On request, both the build length and height can be adapted to specific customer needs without redesigning the whole system.
Each VX7000 allows partially automated job-by-job build area customization, saving time, material, and energy.

High-Performance Printing System

The VX7000 is equipped as standard with four printheads, each approximately 1 meter wide and featuring 7,168 nozzles. This configuration achieves layer times below 100 seconds.
Depending on customer requirements, the system can be expanded with additional printheads to boost throughput or reduced to lower initial investment costs.
A central, pressurized, large-diameter binder supply line ensures fast and uniform filling of all printheads, contributing to consistent part quality and process stability.

Intelligent Material Logistics

Sand supply is managed through a central feed point, easily connectable to customer-side silos.
An industrial mixer blends the base sand with activator and reclaimed sand before it is gently and dust-free distributed via a cartesian robotic system into several buffer silos.
These silos continuously feed the recoater -fully independent from the printing process – with perfectly conditioned sand, guaranteeing uniform layer quality throughout the entire build process.

Precision Engineering for Maximum Accuracy

The VX7000 incorporates several design innovations that maximize dimensional accuracy:

• A cast-concrete build platform mounted on rails – offering superior rigidity and minimal thermal expansion. The use of rails enables the platform to be moved smoothly out of the system into an unpacking position, regardless of the quality of the ground and despite a high load of 60 tons or more.
• Ultra-stiff tubular frame constructions for both the printhead and recoater bridges, featuring fixed and floating bearings to compensate for temperature-induced expansion.
• Form-fit direct drives that maintain high stiffness and eliminate the need for costly and sensitive linear encoders.

A Z-axis system composed of eight vertical column drives – four per side – each using ball screw spindles and electronically synchronized servo drives. The massive cast-iron column bases rest on adjustable feet for independent alignment and simplified installation.

Efficiency Through Smart Cleaning Systems

To minimize binder consumption and reduce operating costs, the VX7000 integrates a multi-stage printhead cleaning system.
Binder expelled during purge routines can be collected and reintroduced into the system.
Additionally, a modular recoater cleaning station ensures rapid maintenance cycles; even if one module fails, the printer continues operation with a reduced build area – ensuring maximum uptime.

Next-Generation Recoater Technology

As with most voxeljet systems, the VX7000 uses an advanced vibrating blade recoater.
This new generation consists of multiple independently driven subunits, electronically synchronized to act as a single cohesive unit.
The result: no harmful vibration effects, perfectly even powder layers, superior print quality at industrial speed and a versatile job width by switching recoater subunits on and off.

The VX7000 defines a new era in industrial binder jet 3D printing:
more precise, modular, and resource-efficient – ready to take large-format additive manufacturing to the next dimension.
