If you own a previous-generation ONE, you can bring it up to date with an upgrade kit that includes the latest PEX2 extruder and advanced print bed options.

It’s important to understand the BigRep ONE’s core features and modular capabilities so you can configure your machine to meet your specific Additive Manufacturing needs.

Which Features Does the BigRep ONE Already Have?

The fifth iteration of the BigRep ONE has an array of fantastic features that give you full control over your prints.

Massive Print Volume

The ONE’s massive one cubic meter build volume firmly establishes it as one of the biggest 3D printers in FFF manufacturing, giving you the ability to unleash your potential in a way that smaller printers simply cannot achieve.

Enclosed Safe Frame

The ONE has a plexiglass enclosure, perfect for monitoring print progress as well as showing your work to any potential visitors. It also provides CE-compliant operator protection: if you open the enclosure mid-print, the machine will stop running. The enclosure reduces temperature fluctuation within the build volume, which is important for maintaining quality and consistency, especially during longer prints.

PEX2 Fiber-Ready Extruder

With up to 40% faster flow rates and a 600g weight reduction from its predecessors, the new Power Extruder (PEX2) offers quicker, smoother movement with less vibration. A dual-drive filament system improves print control, especially with soft materials, ensuring consistent and precise extrusion. The PEX2 also features Slice Engineering’s Mosquito hotend with a copper heat block for faster heating and durable Dianoz diamond nozzle that minimizes clogs and is wear-resistant. The standard nozzle size is 1.0mm, but you can also use 0.6 mm or 2.0 mm.

Semi-Automated Print Bed

The 1m² print bed is covered with a MagBase, a magnetic surface that allows you to easily attach SWITCHPLATES (our flexible and removable print bed surfaces). There are two SWITCHPLATE variants - Classic and Prime. By default, the printer comes with the SWITCHPLATE Classic, which works well with additional adhesives like Magigoo for reliable part adhesion. The ONE also retains its semi-automatic print bed calibration with an integrated inductive sensor, ensuring precise first-layer adhesion and consistent print quality.

If you own a BigRep ONE and opt for the upgrade kit, the SWITCHLATE Prime is included. 

Out-of-Filament Sensor

The BigRep ONE’s out-of-filament sensor pauses all prints when you are out of filament, which is essential for large prints that may use up multiple spools. Simply replace the filament and continue your print.

Intuitive User Interface

For full optimization and calibration of your print, the BigRep ONE is equipped with an intuitive user interface. It helps you remotely load gcodes onto the system, or manually with a USB stick, calibrate the print bed, stop and start operations, and monitor systems in conjunction with BigRep CONNECT.

Filament Enclosure

The filament enclosure has been designed to fit all standard spool sizes, including two spools up to 8 kg. This allows for longer, more continuous printing time.

Standard Camera

For extra-large prints that can take days or even weeks, it’s important to be able to monitor your prints remotely from your computer, tablet, or mobile device. The ONE comes with a webcam attached to your printer, allowing for worry-free prints. The camera also allows you to make time-lapse videos, which can be useful for boosting your marketing outreach.

Which Configuration Works for Me?

The ONE is customizable to meet your specific needs, which begins with the extruder combination you choose.

SINGLE MODE

Single Mode is the most affordable option, a basic configuration with a single Power Extruder and a 1mm nozzle. This option is great for prototyping and testing large-scale prints on a lower budget, however, water-soluble support isn't possible in Single Mode.

DUAL MODE

Our most popular configuration is Dual Mode, which allows for dual extrusion. This is perfect for producing complex geometries when you need water-soluble support for easy removal after printing. Some customers prefer to keep different nozzle sizes on either PEX2 to avoid swapping out nozzles for different prints. Another advantage of dual extruders is having two different primary materials readily loaded for fast switching between filaments.

TWIN MODE

Twin Mode is perfect when you want multiple prints of the same geometry, speeding up your output by 100% and doubling your production. As both extruders work simultaneously, you can print two versions at once, cutting costs and reducing time-to-part by 50%. With Twin Mode, each extruder can print within one-half of the build volume, so Dual or Single Mode is required for larger prints needing build volumes over 0.5m².

Which Additional Add-Ons Are Available?

Some of the useful optional features that you may want to consider:

Keep-Dry Box

If you want to improve quality and make the highest-quality prints possible, then it’s important to keep your materials dry, particularly engineering-grade and hygroscopic filaments. The keep-dry box protects filaments from environmental moisture with rechargeable molecular sieves to absorb humidity, which is especially important for materials such as TPU, BVOH, and HI-TEMP.

Connected Camera

For additional peace of mind, the ONE can be equipped with a USB camera and integrated into BigRep CONNECT, a new monitoring and analytics software that lets you keep track of prints, job queues, material usage, and more. Plus, BigRep CONNECT is free.

Dual Mode Add-On

If you already have Single Mode, you can upgrade as your needs change to print with two extruders instead of one. This is also necessary to install first if you want to print in Twin Mode.

Twin Mode Add-On

If you have Dual Mode already enabled, the Twin kit add-on allows you to upgrade to Twin Mode as well.

SWITCHPLATE Prime

The SWITCHPLATE is a flexible print bed surface engineered for excellent adhesion without additional adhesives. It effortlessly releases parts once cooled, making it ideal for printing with a wide range of materials and ensuring smooth print removal every time. The standard print bed surface for the BigRep ONE is the SWITCHPLATE Classic. You can choose to get an additional SWITCHPLATE Prime, ideal for use with materials like TPU, PETG, and HI-TEMP CF.

Three Personalities of the BigRep ONE

In the race for 3D printing success, knowledge is half the battle. Understanding the full capabilities of the ONE should give you an indication of which features you need to get the most out of your 3D printer. It’s always worth considering exactly what your aims are before tailoring the ONE to meet those desires. To give you an indication, we have three potential combinations you could work with:

The Essentials

When you want a large-format 3D printer at a smaller price, you may want only the Essentials. Opt for a no-thrills, all-business Single Mode ONE configuration perfect for rapid testing and production. The Essentials includes a single fiber-ready Power Extruder with a 1.0mm nozzle. Perfect for beginners, it's a robust solution at minimal cost.

The Sprinter

As the name suggests, the Sprinter is all about speed and is great for ramping up output of batch production. Once design and calibration, material usage, and bed-leveling are set, the Sprinter works quickly and efficiently to simultaneously produce two identical parts. A Sprinter setup could include the Twin Mode extruder configuration with a 1.0mm nozzle, doubling production capabilities, and a CONNECT camera to monitor 3D prints over long periods.

The Perfectionist

The Perfectionist is a ONE configuration suited for applications requiring the best quality using materials that deliver. For complex geometries, Dual Mode is recommended to enable the ONE to print water-soluble support, like BigRep BVOH, together with a range of compatible materials. To keep sensitive materials in optimal condition, add-on the Keep-Dry Box to protect filaments from environmental moisture and dust. For maximum detail, this Perfectionist approach utilizes a 0.6mm nozzle for finer-quality prints and lower layer heights.
