Old Dual-Extruder vs. High-Speed Single Extruder: Which is Better for Education in 2025?

The 3D printing world for schools in 2025 is split into two camps. On one side, you have dual-extruder technology that has proven itself over time. On the other side, you have incredibly fast modern single-extruder machines. As a teacher or school administrator, you need to make an important choice. School budgets are limited, and your decision will affect your classes, student interest, and how your classroom runs for years to come.

This guide looks beyond specific printer names to compare the two main approaches they represent. We won't be doing a direct comparison of a machine like the Flashforge Creator Pro 2 vs the Flashforge 5M. Instead, we'll use them as examples to explore an important question: which type of printer works best for your school's goals? The "best" printer isn't about having the newest features, but about finding the right mix of learning opportunities, how many students can use it, how easy it is to operate, and what kinds of projects students can make.

The Two Options

These two printer types represent completely different ways of thinking about 3D printing. Understanding these differences is the first step in making a smart choice for your school or maker space.

The "Workhorse" Type

This is the established dual-extruder printer. It represents a dependable, flexible, and hands-on way of making things with 3D printing. Think of the machines that have been used in classrooms for years - the ones that taught many students the basics of how plastic filament printing works. The Flashforge Creator Pro 2 is a perfect example of this type.

Its main features include:

• Main Feature: True dual extrusion, often using an Independent Dual Extruder (IDEX) system. This lets you print with two different colors or, more importantly, two different materials at the same time.
• Speed: Slower, more careful print speeds are normal. The focus is on accuracy and being able to use different materials, not on printing fast.
• How it Works: This technology often needs more manual setup. Tasks like making the print bed level and setting the height for two separate nozzles are part of the process, giving students a deeper technical learning experience.
• Design: The design is usually strong and often has an open frame, which lets students see how the machine works. Students can watch every belt, motor, and screw as it operates.

The "Sprinter" Type

This is the modern, high-speed single-extruder printer. It represents the new wave of fast, automated, and user-friendly machines designed for one thing: quick results. The latest generation of CoreXY printers, such as the Flashforge 5M, perfectly shows this approach.

Its main features include:

• Main Feature: Amazing speed is its biggest selling point. With print speeds often over 500-600mm/s, these machines use advanced CoreXY movement systems and smart software features like input shaping.
• Speed: The output is extremely high. What used to take all night to print can now be finished in one class period, allowing for more projects and faster testing of ideas.
• How it Works: The user experience is highly automated. Features like one-click auto-leveling, vibration control, and simple software interfaces are standard. The goal is to remove technical barriers and get users printing successfully with little hassle.
• Design: These printers are often fully enclosed. This design choice makes them safer, helps keep stable temperatures for printing advanced materials, and greatly reduces noise.

Important Educational Factors

How do these two types compare when we look at what schools actually need? Let's examine them across four key areas.

Student Output & Efficiency

For a teacher with a class of 30 students, getting projects from the computer screen into their hands is a big challenge. Here, the Sprinter is clearly better. A high-speed single-extruder can make models in much less time than a traditional Workhorse. This speed isn't just convenient - it's a teaching tool. It allows rapid testing of ideas, which is a key part of design thinking. Students can design a part, print it, test it, and print an improved version all within a day or two, rather than a week.

The dual-extruder Workhorse is much slower and can create delays in a busy classroom. However, IDEX systems have a feature that helps with this: duplication mode. This lets the printer create two identical (smaller) models at the same time, basically acting like two printers in one. While useful, it doesn't match the raw output of a single high-speed machine for most normal-sized student projects.

The lesson for educators is clear: if your main goal is to serve the most students with individual projects and encourage rapid prototyping, speed is your most important factor.

Class Content & Learning

While the Sprinter wins on speed, the Workhorse excels in what it can teach. The dual-extruder's abilities unlock advanced concepts that are simply impossible with a single extruder, making it perfect for engineering, chemistry, and advanced art classes.

The most powerful use is printing with dissolvable supports. Using a material like PVA in one extruder to support a model printed with PLA in the other allows for creating incredibly complex objects. Imagine students designing and printing:

• Fully assembled, print-in-place mechanisms like planetary gear systems.
• Anatomical models with detailed internal spaces that would be impossible to clean out with traditional breakaway supports.
• Architectural models with complex overhangs and interior details.

Once the print is finished, it's simply put in water, and the PVA supports dissolve, leaving a perfect, complex part behind. This ability is a game-changer for teaching advanced engineering and design principles.

Furthermore, the hands-on nature of the Workhorse provides valuable learning by itself. Students who learn to level a bed, calibrate nozzle positions, and fix mechanical problems are gaining a much deeper understanding of the technology. The Sprinter, with its focus on a smooth "design-to-print" process, is excellent for beginning courses where the final object is the goal, not the process.

The lesson for educators: if your classes require teaching advanced engineering principles, exploring complex shapes, or having students master the technology itself, the flexibility of a dual-extruder is invaluable.

Ease of Use & Teacher Workload

A 3D printer is only useful if the teacher has the time and knowledge to operate it. In this area, the high-speed Sprinter is a huge step forward. It is designed for "it just works" functionality. Fully automatic bed leveling, remote print monitoring through a camera, and filament run-out sensors greatly reduce setup time and how often prints fail. This frees up the teacher to focus on teaching, not on machine maintenance. The lower barrier to entry also makes it more accessible for younger students and teachers without extensive 3D printing experience.

The dual-extruder Workhorse has a steeper learning curve. Manually leveling a print bed is a skill. Manually setting up the X, Y, and Z positions of two separate nozzles to make sure they align perfectly is an even more advanced skill. It takes time to learn, practice, and teach. The chance for user error is higher, which can lead to more failed prints and frustration if not managed properly.

The lesson for educators: for a general-use lab, a library maker space, or for teachers who are not 3D printing specialists, the automation of a modern high-speed model is a life-changing improvement.

Safety, Noise, and Environment

A classroom is an active and often crowded environment. Safety and disruption are major concerns. The modern Sprinter type is typically fully enclosed. This single design feature provides multiple benefits:

• Safety: It prevents curious hands from accidentally touching a 200°C hotend or getting caught in fast-moving belts.
• Fume/UFP Control: It contains ultrafine particles (UFPs) and volatile organic compounds (VOCs) released during printing, which is especially important when using materials like ABS or ASA. Many enclosed models also include basic carbon or HEPA filtering.
• Noise Reduction: High-speed printing can be loud. An enclosure significantly reduces the noise, making the printer far less disruptive in a classroom or library.

The classic Workhorse is often open-frame. While this is great for watching the machine's mechanics, it requires more careful placement and student supervision. The noise levels can be higher, and printing with temperature-sensitive materials that need a stable, warm environment (like ABS) is much more challenging without a custom-built enclosure or a separate, well-ventilated room.

The lesson for educators: in a busy, multi-purpose classroom, an enclosed printer is naturally safer, quieter, and less disruptive.

Making Your Choice

To help you decide, let's look at a quick-reference chart and some common school situations.

Situation-Based Guide

The High School Engineering Program

For a program focused on pre-engineering, advanced manufacturing, or robotics, the Dual-Extruder Workhorse is a strong choice. The ability to print with dissolvable supports allows students to create working prototypes and complex mechanical assemblies that are simply not possible on a single-extruder machine. The hands-on setup and troubleshooting align perfectly with an engineering curriculum, teaching students valuable skills that transfer directly to industrial applications.

The Middle School Art Class

For a middle school art class, a general technology lab, or a library maker space, the High-Speed Sprinter is the perfect choice. Its incredible speed allows a whole class to see their creative designs come to life within a few sessions, keeping engagement and excitement high. The ease of use ensures that the focus remains on creativity and the design process, not on struggling with machine operation. Safety and low noise are also huge advantages in these environments.

The K-12 District-Wide Initiative

For a district looking to equip multiple schools, the best solution is often a mixed fleet. Equip general-purpose labs and libraries in elementary and middle schools with several High-Speed Sprinters for daily use by all students. Then, place one or two Dual-Extruder Workhorses in a specialized "advanced projects" lab at the high school level. This layered approach provides widespread access while also offering high-end capabilities for students in advanced STEM pathways.

Final Thoughts and Outlook

There is no single "winner" in the debate between the Workhorse and the Sprinter. The correct choice depends entirely on your educational approach. Are you teaching the craft of 3D printing itself, or are you using the 3D printer as a tool to help with other forms of creation?

As of 2025, the industry trend is clearly toward more speed and greater automation. The Sprinter type represents the present and future of accessible 3D printing. However, the unique and powerful abilities of dual extrusion, particularly with dissolvable materials, ensure that the Workhorse remains a relevant and essential tool for specialized, high-level education. Before you buy, assess your primary need—is it flexibility or volume? The answer will guide you to the technology that best serves your students and empowers them as the next generation of creators.

Frequently Asked Questions (FAQ)

Q1: What about material compatibility (PLA, PETG, ABS, TPU)?

Both printer types generally handle standard materials like PLA and PETG very well. The enclosed nature of most high-speed Sprinters gives them an advantage with high-temperature materials like ABS and ASA, as the stable surrounding temperature prevents warping. Flexible materials like TPU can be challenging on any machine, but modern direct-drive extruders on both types have made it much more reliable. The unique strength of the dual-extruder Workhorse is its ability to pair these standard materials with a dissolvable support material like PVA.

Q2: Is one high-speed printer better than two older, slower printers for the same price?

This is a trade-off between output and backup options. One high-speed Sprinter can often match or even exceed the total output of two older Workhorses, and it only requires the maintenance and management of a single machine. However, having two printers means that if one breaks down for maintenance, you still have 50% of your printing capacity available. For a single classroom, the simplicity and speed of one high-speed machine is often the better choice. For a larger lab, having multiple machines provides valuable backup.

Q3: How much of a difference do dissolvable supports really make?

They make a huge difference for a specific type of objects. Imagine trying to print a model of a ship inside a bottle. With a single extruder, the internal supports holding up the ship would be impossible to remove. With a dual-extruder, you print the bottle in PLA and the internal supports in PVA. After printing, you put the object in water, the PVA dissolves, and you are left with a "magic" object that would otherwise be impossible to create. This is the power of dissolvable supports: they unlock true geometric freedom.

Q4: With the rise of AI in design, does printer speed matter more than ever?

Yes, absolutely. As AI-powered design tools become more accessible to students, they can create and test dozens of design variations in minutes. A slow printer becomes an immediate bottleneck to this new, accelerated creative process. A high-speed printer that can keep pace with a student's AI-assisted imagination becomes an even more valuable tool, allowing them to physically test ideas almost as fast as they can generate them.
