Co Print Quadro Progress Update #3

We are pleased to share some important developments with you in the third installment of our Progress Update series, where we cover the development process of Co Print Quadro in detail.

First of all, the two questions we have received most frequently from our community have been: how much will Quadro cost, and when will the Kickstarter campaign begin? In this update, we will share the Kickstarter launch date and pricing details with you in full.

In addition, we will also publish a comprehensive video where you can take a closer look at many important aspects of Quadro directly on the machine itself, including its toolheads, calibration system, Y-axis mechanics, and everyday operation.

Now, let’s take a detailed look at where we are in Quadro’s development process and the latest progress we’ve made.

Our Kickstarter Upcoming page is now live! In less than the first 24 hours, the project surpassed 550 followers. On top of that, while Quadro was still in the Upcoming stage, it received Kickstarter’s “Project We Love” badge, awarded to projects that Kickstarter highlights and believes in.

If you are not following Quadro on Kickstarter yet, you can visit our Upcoming page through this link and select “Notify me on launch” to be notified as soon as the campaign goes live.

We are also preparing special gifts for supporters who purchase Quadro within the first 48 hours of the campaign, along with giveaways offering the chance to win additional Quadro units.

We have set Quadro’s Kickstarter Super Early Bird price at $649. This represents a 28% discount compared to the $899 MSRP.

When developing Quadro, our goal was not simply to create another 3D printer capable of multicolor printing. We wanted to build a high-quality and mechanically robust platform that users could rely on for years. This is why approximately 70% of Quadro is made from aluminum and metal components, and its motion systems were designed around the same principles of rigidity commonly associated with CNC machinery. When four independent toolheads and an almost waste-free multicolor and multi-material printing system are added to this platform, Quadro becomes the only printer to offer this experience in a bed-slinger architecture. So the $649 Super Early Bird price represents not only four toolheads, but also Quadro’s mechanical quality, durability, and the unique printing architecture we developed from the ground up.

However, we have not forgotten the users who supported us early through our Early Reservation Ticket program.

We are keeping the promise we made to supporters who purchased an Early Reservation Ticket by the end of August 25, 2026, providing them with $200 in total benefits. These users will receive $150 cashback, effectively allowing them to purchase the $649 Super Early Bird Quadro for $499. In addition, they will receive $50 in store credit that can be used across the entire Co Print Store.

Our goal is to make Quadro available under the most advantageous conditions possible to the members of our community who supported us from the early stages of development and helped shape the project through their feedback.

If you have not purchased an Early Reservation Ticket yet, there is no need to worry. Special benefits are still available for early supporters who reserve from August 26, 2026 onward.

These users will receive $75 cashback together with $25 in store credit valid across the Co Print Store. This brings the effective Quadro price down to $574, approximately 36% below the $899 MSRP.

For those who read this update but missed Stage 1, we’ve decided to extend Stage 1 until September 1 so that everyone who is closely following Quadro still has the opportunity to access it at the best possible price.

You can now secure your Early Reservation through our website and make sure you don’t miss the $200 total benefit.

You can click here to purchase a Quadro Early Reservation Ticket and review all the details of the reservation program.

We have also extensively updated Quadro’s landing page. If you have not explored it yet, you can visit the updated page here and discover all of Quadro’s features in detail.

On the reservation page, we explain Quadro’s key features through visuals and explanatory animations. Now, let’s take things one step further and look closely at how these features actually work directly on Quadro itself.

Based on the responses we received from the survey we previously shared with you, the feature that stood out most clearly was Quadro’s four independently operating toolheads on a single axis.

So let’s begin with the system at the heart of Quadro and take a closer look at how four independent toolheads operate on a single axis.

When you first look at Quadro’s X-axis from the outside, it may not be immediately obvious how all four toolheads are able to move completely independently from one another. That is because the system responsible for moving the toolheads has been carefully integrated inside the X-axis extrusion itself.

Once the front cover of the X-axis profile is removed, the actual motion system becomes visible. Running across the entire axis are four separate belts positioned one above another, together with the pulley systems that support them throughout their travel.

Each toolhead has its own independent belt and stepper motor. In other words, the four toolheads do not share a common motion system; each one is controlled separately by its own motor. Each belt also has its own automatic tensioning mechanism, helping all four belts maintain an ideal and consistent level of tension.

The four toolheads receive their movement from these belt, pulley, and motor systems and travel along the same 12 mm linear rail. This structure allows the toolheads to move smoothly and precisely across the X-axis with high rigidity and minimal play.

To keep the X-axis mechanically balanced, we also positioned the motors and tensioning mechanisms symmetrically. The motors and tensioning mechanisms for Toolheads 1 and 2 are positioned on the left side of the X-axis, while those for Toolheads 3 and 4 are positioned on the right. This layout not only creates a cleaner and more symmetrical appearance, but also contributes to a more balanced weight distribution across the X and Z axes.

How Can Four Toolheads Access the Entire Build Area Without Passing Each Other?

Another aspect that may not be immediately obvious is how the four toolheads can move along the same linear rail without passing through or over one another.

We frequently receive questions such as: Can the toolheads pass each other? If they cannot, how can all four toolheads access the entire 300 × 300 mm build area?

The toolheads do not pass over one another. Instead, Quadro has extended parking areas on both the left and right sides of the X-axis called Qdock Stations. Each Qdock Station is designed to accommodate up to three toolheads at the same time.

This allows inactive toolheads to move outside the active print area into the Qdock regions, clearing the path for whichever toolhead is currently printing.

For example, suppose Toolhead 1 needs to print. The toolheads positioned in front of it move toward the Qdock Station on the right. Toolhead 2 can travel all the way to the outermost third parking slot, while the other toolheads move into their assigned parking positions. This completely clears the path in front of Toolhead 1.

As a result, Toolhead 1 is able to use not only the portion of the build plate closest to it, but the entire 300 × 300 mm build area.

The same principle applies to all other toolheads. Inactive toolheads are parked in either the left or right Qdock Station as needed, allowing all four toolheads to access the full 300 × 300 mm build area without ever needing to pass over one another.

One of the most important aspects of any bed-slinger printer is the mechanical structure of the Y-axis, since the build plate is constantly moving. When designing Quadro’s Y-axis, we took inspiration from mechanical principles used in industrial CNC milling machines to create a strong and stable structure.

First, the main component supporting the build plate, linear rails, and Y-axis motion system is connected directly to Quadro’s metal and aluminum chassis. There are no flexible plastic components between these structural connections. This means that the forces generated by the moving build plate are transferred directly through the metal structure.

To safely reach high speeds and acceleration values, structural strength alone is not enough. The linear rails used on the Y-axis must also be installed with a high degree of parallel accuracy, and that parallelism needs to be maintained during assembly. Even small alignment differences can increase motion resistance and negatively affect motion quality at higher speeds.

For this reason, the main carrier on which Quadro’s linear rails are mounted is designed as a single-piece aluminum extrusion with high flatness accuracy.

Once the linear rails are positioned on this carrier surface, additional mounting components are used to apply equal force from both sides and keep the rails correctly positioned. These components are tightened in a controlled manner using torque wrenches, helping maintain the parallel alignment of the two linear rails throughout assembly.

The bed carriage, which travels along these linear rails and carries the build plate, is another critical component directly affecting Y-axis performance.

On many 3D printers, this part is typically manufactured from laser-cut and bent sheet metal. However, components produced through bending processes can develop flatness variations or slight axis misalignments as a result of manufacturing tolerances.

To avoid this issue, we took a different approach with Quadro’s bed carriage. It is manufactured as a single piece from 4 mm thick aluminum extrusion. Because no bending process is required, geometric variations caused by bending tolerances can be avoided, resulting in a flat, durable, and repeatable support structure.

This helps the build plate maintain its shape during movement and minimizes unwanted flex during calibration.

However, building a strong mechanical structure is only part of the equation. How motion is transferred into that structure is equally important.

Quadro uses two independent stepper motors with 48 mm body lengths to drive the Y-axis. One motor is positioned at the front of the axis and the other at the rear.

Instead of operating both motors through the same belt system, each motor has its own independent belt, pulley, and automatic tensioning mechanism. This mechanically separates the two drive systems from one another.

The two motors grip the bed carrier at different points and move synchronously. Rather than applying all motion force through a single point, distributing it between two points helps the build plate move in a more controlled way at high speeds and accelerations while also balancing the load across the Y-axis.

When all of these elements are considered together, the single-piece carrier structure, precisely aligned dual linear rails, 4 mm aluminum bed carriage, and dual independent motor system form the core mechanical foundation of Quadro’s Y-axis.

Quadro’s Z-axis has also been reinforced to comfortably support the X-axis mechanism and its four toolheads.

The most powerful stepper motor on the printer is used to drive the Z-axis. This allows the combined load of the X-axis and four toolheads to be moved vertically in a controlled and stable manner.

But we did not rely on motor power alone to reinforce the Z-axis. The filament holder stations positioned behind the Z towers on both sides of the printer were also specifically designed to serve as structural support elements.

Each of these components is approximately 40 mm thick. While carrying four filament spools, they also support the Z towers from behind and help distribute structural forces more evenly into the chassis. With two filament stations on the right and two on the left, the structure is supported from both sides.

Although these parts are made from plastic, their thickness and geometry, designed around load distribution, allow them to function not only as filament holders but also as structural support elements that contribute to Quadro’s overall rigidity.

To make effective use of the footprint created by the X-axis parking areas and reduce the amount of desk space Quadro requires, we positioned the filament holder units directly behind these parking zones. Two filament stations are located on the right and two on the left.

Thanks to this arrangement, Quadro’s overall desktop footprint does not increase even when all four filament spools are loaded. Compared with similar bed-slinger printers that require an external AMS-like filament management system to be positioned beside the printer for multicolor printing, this creates a significantly more compact workspace.

With all four filament spools loaded, Quadro’s total desktop footprint is 780 × 620 × 515 mm.

We also designed the filament loading process to be as simple as possible. The filament spool is placed directly onto the corresponding station, and the desired toolhead is selected from the interface before starting the Load function.

The filament is manually guided from the filament inlet on the station toward the toolhead. Once the toolhead detects the filament, it automatically grips it and completes the loading process.

Once loading has been completed successfully, the status light on the toolhead illuminates in the color of the loaded filament. This allows the user to confirm at a glance both that the filament has been loaded successfully and that it has been assigned to the correct toolhead.

When all of these systems come together, they make Quadro a highly stable 3D printer that brings a waste-free multi-toolhead architecture to a bed-slinger platform.

Quadro can reach movement speeds of up to 600 mm/s and acceleration values of up to 10,000 mm/s². Each of its four independently operating toolheads is equipped with a hotend capable of 24 mm³/s flow and temperatures of up to 300°C.

This makes it possible to print with common materials such as PLA, PETG, and certain types of TPU, along with carbon-fiber-reinforced variants of these materials. With an enclosure, engineering materials such as ABS that benefit from higher temperatures and a controlled environment can also be used. Our goal was to bring all of these capabilities together in a system that remains simple to use and compact on a desktop.

One of Quadro’s greatest advantages becomes especially clear during multicolor printing.

In single-nozzle multicolor systems, every color change requires the existing filament to be cut or retracted, the new filament to be fed into the hotend, and the remaining material inside the nozzle to be completely cleared. This process can produce significant amounts of filament waste through purge towers, flushing, or what is commonly referred to as “poop.”

Quadro, on the other hand, has a separate toolhead and a separate nozzle for each color.

This means there is no need to repeatedly retract and reload filament or purge large amounts of material simply to clear the previous color from the nozzle. As the active toolhead moves into its parking area, the next toolhead can immediately continue the print.

A tool change can be completed in approximately 3 seconds.

Quadro can technically produce multicolor prints without generating any purge or cleaning tower at all. However, when a toolhead has remained inactive for some time, small pressure differences can develop inside the nozzle when extrusion begins again. To equalize this pressure before returning to the model and ensure more consistent first extrusion lines after a tool change, Quadro uses a small pressure-balancing tower.

This tower serves a different purpose from the conventional purge towers used by single-nozzle multicolor systems. Its purpose is not to clear the previous color from the nozzle, but simply to stabilize extrusion pressure with a short extrusion before the toolhead returns to the model. As a result, the amount of filament used is extremely small.

More importantly, unlike single-nozzle systems, this waste does not increase dramatically depending on the size of the model, the number of color changes throughout the print, or the combination of colors being used. Because every color in Quadro has its own nozzle, there is no need to purge the previous material, keeping waste consistently close to a minimum throughout the print.

This architecture is the foundation of Quadro’s “waste-free” approach: the goal is not to claim that absolutely no filament is ever used outside the model, but rather to reduce unnecessary purge waste caused by color changes to the lowest practical level.

Thanks to this architecture, compared with multicolor systems that change filament through a single hotend, Quadro can reduce filament waste by approximately 90% while saving up to 70% of the time required for multicolor printing.

Ultimately, Quadro’s four independent toolheads do more than simply change the way colors are switched. They create a more efficient workflow that reduces print time, filament consumption, and the overall cost of multicolor printing at the same time.

Ahead of the Kickstarter campaign, we wanted to share not only what Quadro can do, but also why these features were developed, what problems they were designed to solve, and which engineering principles the product was built around.

Because for us, Quadro is more than just a new 3D printer. It is the most comprehensive product we have created by bringing together years of experience in multicolor printing technologies, feedback from our users, and solutions we have developed for real problems we have encountered across the industry.

Since 2022, Co Print has focused on giving 3D printers multicolor and multi-material printing capabilities. We were among the early companies to focus specifically on multicolor FDM printing before it became as widespread as it is today. Starting with our first Multi-Filament Module, we have shaped every product we developed around the same fundamental question: How can multicolor printing be made more efficient?

We began developing our first products during the era when Bowden systems were still widely used. Later, as Klipper transformed the 3D printing ecosystem, our approach evolved beyond simply creating new products. We also focused on enabling users to upgrade the printers they already owned and bring next-generation capabilities to existing machines.

This process taught us not only how to develop multicolor printing systems, but also how extrusion, filament management, toolhead design, calibration, software, motion systems, and user experience all need to work together.

Quadro is the natural result of all that experience.

This time, instead of adding new capabilities to an existing printer, our goal was to bring years of multicolor printing experience together in a single machine designed from the ground up according to our own principles: four independent toolheads, minimal filament waste, fast tool changes, robust mechanics, simple operation, and the lowest practical running costs.

When developing Quadro, we did not see our community simply as the future users of the product. The surveys we shared, the feedback we received, your questions, and the comments gathered throughout development all directly influenced how the product evolved. That is why we can confidently say that Quadro has been developed together with our community, for our community.

After years of upgrading different 3D printers and giving them new capabilities, we are now bringing all of that experience together in our own 3D printer for the first time.

Quadro is now getting ready to enter the market.

We invite you to join us for the Quadro Kickstarter campaign launching in October 2026. To be among the first to know when the campaign goes live and to make sure you do not miss the best early-supporter pricing, we recommend following our Kickstarter Upcoming page, which is already live.

You can share your thoughts, questions, and suggestions about Quadro with us in the comments. Feedback from our community has played an important role throughout development and will continue to do so going forward.

We are also starting to work more closely with beta testers, reviewers, and community creators as Quadro moves closer to launch. We are already seeing creators produce preview content around Quadro, and we would love to support more of these community-driven projects.

If you are planning to create content about Quadro, we may be able to provide additional media assets, product information, test print results, footage, or other materials that can help you create more detailed and accurate content.

At the same time, we are continuing to collect applications from content creators, influencers, and beta testers who would like the opportunity to test Quadro directly. If you are interested, you can submit your request through this form, and our team will get in touch with selected applicants.

We are also activating Kickbooster ahead of the Kickstarter launch. This means creators and community members who would like to support the campaign can begin sharing their unique referral links and track the people they refer before the campaign goes live. Once Kickstarter launches, eligible purchases made through those referrals will generate commissions through the Kickbooster program.

We’re excited to see how the community shares, tests, and experiences Quadro as we get closer to launch.

Thank you for being part of Quadro’s development journey with us.

See you in the next Progress Update!
