Large-format 3D printing for full-scale parts

The BigRep ONE is an award-winning large-format 3D printer designed to produce full-scale parts with a one-cubic-metre build volume. German-engineered to work around the clock, the system is used by designers, innovators, manufacturers, and research teams that need reliable large-scale additive manufacturing.

With over 350 systems installed worldwide, the BigRep ONE is built for prototyping, production, and other demanding applications where part size, repeatability, and access to in-house fabrication matter.

Key features of the BigRep ONE 3D printer

Large-format printing capacity

The machine is designed for massive 3D prints up to 1000 x 1000 x 1000 mm. That build space supports full-scale prototypes, oversized design models, and complex geometries that exceed the limits of smaller desktop systems.

Fibre-ready Power Extruder with interchangeable nozzles

The BigRep ONE includes one BigRep fibre-ready Power Extruder (PEX). Interchangeable 0.6 mm, 1.0 mm, and 2.0 mm nozzles allow the printer to be set up either for finer detail or for high-flow additive manufacturing.

Heated print bed with semi-automatic levelling

The heated print bed uses a polyimide foil coating to support adhesion throughout the printing process. An integrated inductive sensor enables semi-automatic print bed levelling, helping streamline calibration and support consistent output.

Accessible frame design and optional enclosure

The open frame allows unobstructed print monitoring and access to the print bed from three sides. This layout makes it easier to inspect print quality and progress during large-format jobs.

The optional enclosure add-on adds a more constant printing environment and CE-compliant operator protection. The transparent housing also includes a safety concept with automatic door sensors.

Filament handling for long print jobs

The redesigned filament enclosure fits all standard spool sizes, including two spools up to 8 kg. An out-of-filament sensor pauses a print when a spool runs empty, which is especially useful during very large builds.

The optional Keep-Dry Box protects filament from dust and moisture, which is particularly useful for materials that are sensitive to humidity.

Touch panel controls and remote monitoring features

An intuitive graphical user interface on the touch panel PC provides access to remote load functions, print parameter changes, webcam-based progress checks, and resume-after-power-failure capability.

The optional Camera Add-On allows print monitoring via webcam from a computer or mobile device.

Extruder configurations and modular add-ons

The BigRep ONE can be configured in single, dual, or twin extruder modes. This modular approach allows the system to be matched to current production needs and expanded later as workflows evolve.

Modules and add-ons can be selected based on application requirements, including enclosure, camera, Keep-Dry Box, and custom colour options.

• Enclosure Add-On: Transparent housing with automatic door sensors for a more constant printing environment and added safety.
• Camera Add-On: Remote print monitoring via webcam from a computer or mobile device.
• Keep-Dry Add-On: Filament protection from dust and moisture for improved material handling.
• Custom Colour Add-On: Replaces the standard BigRep orange corners with a chosen paint colour.

Applications for large-scale additive manufacturing

Design and architecture

The BigRep ONE is used for fine art, museum displays, film props, and innovative installations. Digitizing the fabrication process opens more possibilities for large-scale creative work and helps designers produce projects that would be difficult to create by other methods.

Forms and moulds

3D printed patterns and moulds can replace expensive CNC-milled or hand-crafted traditional forms. Producing these tools in-house helps modernize early casting workflows, speed up iteration, reduce material costs, and simplify logistics.

Prototypes

Large-scale prototyping can be completed quickly and cost-efficiently, which supports more design cycles without raising fabrication costs. This makes the printer useful for innovators who need frequent iteration and full-scale evaluation.

Research and education

Universities and research teams use the BigRep ONE for hands-on training, advanced technology instruction, and rapid iteration during experimental work. In-house access helps avoid third-party bottlenecks that can slow development and testing.

What the BigRep ONE is built to deliver

The BigRep ONE is built for users who need large-format 3D printing with accessible operation, modular expansion, and dependable long-duration printing features. Its combination of one-cubic-metre capacity, PEX extruder, semi-automatic bed levelling, open-frame access, and upgradeable configuration makes it suitable for production tooling, creative fabrication, research environments, and full-scale prototype development.
