Running on open-source Marlin firmware, the TAZ Workhorse brings together the freedom of open-source development with advanced hardware designed for larger print projects. But how does it fare when compared to other professional-grade 3D printers on the market? Let’s break it down.

1. Build Volume and Versatility

One of the biggest advantages of the LulzBot TAZ Workhorse is its large build volume, which measures 280 x 280 x 285 mm. This makes it a highly versatile machine that can handle large-scale projects or produce multiple parts in a single print job. Compared to other professional-grade 3D printers, which may be more limited in size, the Workhorse is ideal for printing big, functional parts such as jigs, fixtures, and prototypes.

The dual extrusion capabilities also allow users to print with multiple materials or create complex structures using both standard and soluble support materials. This versatility gives the Workhorse an edge for professionals who need flexibility in material choice and print size.

2. Material Compatibility

The TAZ Workhorse is compatible with a wide range of filaments, thanks to its modular print head system. The printer can handle standard filaments like PLA and ABS, but also works with more advanced materials such as nylon, polycarbonate, and composites like carbon fiber and metal-filled filaments. This feature puts it on par with other industrial-grade 3D printers that are designed to work with engineering-grade materials for more robust and functional prints.

However, some competing printers, especially those designed for resin-based printing or high-temperature materials, may offer an even wider selection of specialized materials. Nevertheless, for FFF-based systems, the LulzBot TAZ Workhorse holds its ground in terms of material versatility.

3. Open-Source Firmware and Customization

Running on open-source Marlin firmware, the TAZ Workhorse allows for a high level of customization, which is appealing to engineers and professionals who like to tinker with machine settings and firmware. Open-source hardware and software mean that users have complete control over their print settings, offering the flexibility to modify the printer as needed for specialized projects.

This open-source approach contrasts with some closed-source 3D printers, which may limit user control over software and hardware modifications. As a result, the TAZ Workhorse offers greater flexibility, particularly for users who prefer to have full control of their printer’s ecosystem. However, with more freedom comes a learning curve—novices or users unfamiliar with open-source systems may find the setup and operation of the TAZ Workhorse more challenging than plug-and-play machines with proprietary systems.

4. Precision and Print Quality

The TAZ Workhorse is equipped with hardened steel components, which not only make it more durable but also enable the printer to handle more abrasive materials like carbon fiber-filled filaments. The printer also comes with a Borosilicate glass bed with a PEI surface, offering better first-layer adhesion and consistent printing performance.

In terms of precision, the LulzBot TAZ Workhorse offers a layer resolution of 50 to 400 microns. This level of precision places it in line with other professional-grade FFF 3D printers. However, compared to resin-based systems like SLA (Stereolithography) or DLP (Digital Light Processing) printers, which can achieve much finer resolutions, FFF systems like the TAZ Workhorse may not match the same level of detail for applications requiring intricate designs or very fine features.

5. Print Speed

When it comes to print speed, the TAZ Workhorse performs at an average speed of around 30–60 mm/s, depending on the material and settings. This is fairly standard for FFF 3D printers in its class. However, it does not compare to industrial machines optimized for speed, such as resin printers or Selective Laser Sintering (SLS) systems, which can often produce parts much faster due to different printing methods.

If print speed is a top priority, some professional-grade machines designed specifically for high-throughput production might offer better results. However, for professionals working on functional prototypes and end-use parts, the trade-off in speed for quality and versatility is acceptable with the TAZ Workhorse.

6. Ease of Use

Despite its powerful capabilities, the LulzBot TAZ Workhorse is designed to be user-friendly. It features automatic bed leveling, making setup easier for users who may not be familiar with manual calibration. Additionally, the machine comes with preconfigured print profiles in Cura LulzBot Edition, so users can get started printing quickly without needing to manually adjust the settings for every print.

This makes the TAZ Workhorse a solid option for both experienced users and those who are transitioning into more professional-grade 3D printing but want the ease of automated features. However, some fully automated machines on the market may provide a smoother experience for those who prioritize simplicity and don’t want to engage with manual adjustments or open-source customization.

7. Pros and Cons of the LulzBot TAZ Workhorse

Pros:

• Large Build Volume: Ideal for printing large parts or multiple parts in one go.
• Wide Material Compatibility: Can handle standard and engineering-grade materials, including composites.
• Open-Source Flexibility: Offers complete control over hardware and software modifications.
• Durability: Built with hardened steel components for long-term use and compatibility with abrasive filaments.
• Dual Extrusion: Allows for multi-material and complex prints.
• User-Friendly Features: Includes automatic bed leveling and preconfigured profiles to make printing easier.

Cons:

• Learning Curve: Open-source systems may be challenging for users unfamiliar with customization and tinkering.
• Average Print Speed: Not the fastest compared to industrial or resin-based systems.
• Size and Weight: Its larger size might be a limitation in smaller workshops or office spaces.
• Cost: At $2,950, it’s more expensive than many entry-level or mid-range 3D printers, although it’s more affordable compared to higher-end industrial machines.

8. How Does the LulzBot TAZ Workhorse Compare?

When compared to other professional-grade 3D printers, the LulzBot TAZ Workhorse holds its own in terms of build volume, material versatility, and open-source capabilities. While it doesn’t offer the ultra-high precision of SLA or resin printers or the speed of high-throughput SLS systems, it strikes a balance between cost, reliability, and flexibility.

For engineers, designers, and prosumers who need a durable, flexible machine for large-scale projects and functional prototypes, the TAZ Workhorse is a solid investment. It offers a balance of advanced features and user-friendly tools that make it a competitive option in the professional 3D printing space.

If material flexibility and open-source customization are priorities, the TAZ Workhorse excels. For users who need higher precision, faster speeds, or a more automated system, there may be better options in other categories of professional-grade 3D printers, depending on the specific requirements of the project.
