Review: The Lulzbot TAZ 6 - #OpenIsDefault for the win?

Overview

The LulzBot TAZ 6 is a plus-size 3D printer by Aleph Objects that presents a significant leap in their line of 3D printers. It boasts a large build volume, aluminum machine profile frame, and a mix of metal and 3D printed parts for customization without compromising on strength and reliability. Its design reflects Aleph Objects' experience and attention to detail, incorporating features like 12mm round linear rails, self-lubricating bushings, and a massive trapezoid spindle for the Z-axis.

Build Volume and Bed

The TAZ 6 offers a substantial build volume with a 280mm by 280mm usable area on its bed and a maximum print height of 250mm. It employs a glass bed with a silicon heater mat and a PEI sheet on top, which is identical to the setup on the LulzBot Mini but larger. The bed is held down with precision-machined washers, facilitating automatic bed compensation.

Extruder and Hotend

Equipped with a Wade's extruder and an Aleph Objects version of the Hexagon hotend, the TAZ 6 uses three fans on its carriage to ensure even cooling from both sides. The quick-swap extruder carrier, which is easily swappable with just one screw, allows for rapid changes to dual extruder setups or for printing flexible filaments with the LulzBot Flexystruder.

Electronics and Software Compatibility

On the electronics front, the TAZ 6 is powered by the Rambo board, featuring an integrated Arduino Mega with a simple graphical LCD screen and SD card reader. It comes with a specially customized version of Cura, pre-configured with a comprehensive range of filament profiles. This customized Cura software and extensive documentation, thoroughly made with free and open-source software, make the printer accessible for users at various skill levels.

Open Source and Community Driven

Aleph Objects stands out for its commitment to open-source principles. All files related to the TAZ 6, including documentation, 3D models, and testing instructions, are readily available under a Creative Commons license. This aligns with the company's philosophy of transparency and community involvement in product development and improvement.

Setup and Ease of Use

The TAZ 6 is designed for a smooth out-of-the-box experience. Assembly is minimal and straightforward, boasting an easy setup process complemented by detailed manuals and an included tool bag. Aleph Objects’ approach to auto-leveling using precision machined washers enhances the printer's reliability and ease of use, significantly reducing setup time before printing.

Performance and Print Quality

Performance-wise, the TAZ 6 prioritizes quality and reliability over speed, with moderate acceleration settings and a maximum print speed that promotes detail resolution. The test results across various materials, including PLA, ABS, nylon, and HIPS, demonstrate the TAZ 6's capacity to handle a wide range of filaments effectively. The auto-leveling feature, coupled with the printer's solid build and well-tuned default profiles, contributes to its exceptional print quality and reliability.

Considerations

Despite its robust design and performance, the TAZ 6 is not without minor drawbacks. Early models exhibited some alignment issues with the belt path and needed adjustments to frame alignment due to shipping. Additionally, the reliance on 3mm filament and the potentially higher operating costs due to its power consumption are factors worth considering. Nonetheless, these issues are relatively minor and do not significantly detract from the printer’s overall performance and value.

Conclusion

The LulzBot TAZ 6 emerges as a compelling option among high-end 3D printers, offering an excellent balance of size, performance, and ease of use. Its commitment to open-source principles, combined with strong community support and comprehensive documentation, makes it a versatile tool suitable for a wide range of users, from enthusiasts to professionals. The TAZ 6's ability to deliver high-quality prints reliably, along with Aleph Objects’ ongoing support and updates, ensures its place as a top contender in the 3D printing market.
