The Nextruder: A Deeper Dive into Prusa’s Innovation

The Nextruder is arguably the centerpiece of the Original Prusa MK4, representing a significant leap forward in extruder technology for Prusa Research. It’s not just an incremental upgrade.

It’s a fundamental redesign aimed at enhancing reliability, precision, and user experience.

Think of it as Prusa’s engineering team saying, “How can we make this even more bulletproof and intuitive?”

At its core, the Nextruder integrates several key components that were previously separate or less optimized. The most notable inclusion is the load cell sensor, which is a must for automatic first layer calibration. Instead of relying on a separate P.I.N.D.A. or SuperPINDA probe, the Nextruder uses the nozzle itself as the probe. This means the system directly measures the force exerted by the nozzle on the print bed, leading to incredibly accurate Z-offset calibration. What does this mean for you? Virtually perfect first layers, every single time, without manual tweaking. It’s like having a master craftsman fine-tune your bed level before every print.

The Nextruder is a direct drive system, meaning the motor that pushes the filament is located directly above the hotend. This design offers several advantages:

Superior control over filament flow: Essential for printing flexible materials like TPU, as it minimizes the distance filament needs to travel unguided.
Reduced stringing and blobs: Precise retraction control is easier with a direct drive, leading to cleaner prints.
Easier material changes: The filament path is shorter and more direct, making loading and unloading filament smoother.

Another smart design choice is the toolless nozzle change system. Prusa has moved away from the traditional threaded heat break and nozzle assembly, opting for a quick-swap design. This means you can change nozzles in a matter of seconds, without needing wrenches or risking damage to the heat break. It’s incredibly convenient, especially if you frequently switch between different nozzle sizes or materials. This quick-change mechanism also contributes to better thermal performance and reduces the chance of clogs related to improper nozzle installation.

Furthermore, the Nextruder boasts planetary gears for improved torque and more consistent filament extrusion. This geared system provides greater pushing power for the filament, making it easier to handle difficult materials and ensuring a steady flow rate, which translates directly into smoother print surfaces and more accurate dimensions.

Let’s break down some of the key improvements the Nextruder brings:

Load Cell Sensor:
- Function: Measures the force of the nozzle touching the print bed.
- Benefit: Enables automatic, highly accurate first layer calibration without manual intervention. Eliminates Z-offset issues.
- Impact: Consistent first layers, leading to fewer failed prints and better adhesion.
Toolless Nozzle Change:
- Function: Quick-swap mechanism for nozzles.
- Benefit: Fast and easy nozzle replacement without tools. Reduces downtime.
- Impact: Encourages experimentation with different nozzle sizes and materials.
Direct Drive with Planetary Gearing:
- Function: Filament motor directly above the hotend with high-torque gears.
- Benefit: Enhanced control for flexible filaments, reduced stringing, precise extrusion.
- Impact: Wider material compatibility, higher print quality, particularly with tricky filaments.
Integrated Electronics:

Input Shaper and Pressure Advance: Unlocking Speed and Quality

If you’ve been following the 3D printing scene, you’ve heard the buzzwords: input shaper and pressure advance. These aren’t just technical jargon. they are fundamental game-changers that allow modern 3D printers like the Prusa MK4 to achieve speeds that were previously unthinkable on a consumer FDM machine, all while maintaining or even improving print quality. Think of it as a finely tuned suspension system for your print head.

What is Input Shaper?

Input shaper is a sophisticated software algorithm designed to mitigate ringing and ghosting artifacts that occur at higher printing speeds. When a print head rapidly changes direction, the inertia of the moving parts the print head, the motors, the frame causes vibrations. These vibrations manifest as “ghost” lines or ripples on the printed surface, especially visible on parts with sharp corners or embossed text. This is often referred to as “ringing” or “ghosting.”

Input shaper works by predicting and canceling out these vibrations. It does this by adding small, precisely timed counter-movements to the print head’s motion profile. It’s like gently pushing a swinging pendulum at just the right time to make it stop swinging immediately. The MK4 incorporates an accelerometer in the Nextruder to automatically calibrate the input shaper for your specific machine, even accounting for its placement on your desk. This auto-calibration is a huge advantage, as manual tuning can be complex and time-consuming on other machines.

Benefits of Input Shaper on the MK4:

Significantly Higher Print Speeds: Allows the printer to move faster without sacrificing print quality. You can push the acceleration and jerk settings much higher.
Elimination of Ringing/Ghosting: Prints come out cleaner, smoother, and with sharper details, even at speeds exceeding 200 mm/s.
Automatic Calibration: The MK4 handles the complex calibration process for you, ensuring optimal performance out of the box. No more guessing or tedious manual tuning.

What is Pressure Advance?

Pressure advance also known as Linear Advance in some firmwares addresses a different but equally important aspect of print quality: consistent extrusion during speed changes. Imagine you’re driving a car and you suddenly hit the brakes, then stomp on the gas. If you don’t adjust your acceleration and braking smoothly, you’ll jerk around. Similarly, when a 3D printer accelerates into a line segment or decelerates before a corner, the pressure inside the nozzle can fluctuate, leading to:

Blobs at corners: Excess filament is pushed out when the printer slows down.
Gaps or under-extrusion at the start of lines: Not enough pressure has built up as the printer speeds up.

Pressure advance anticipates these pressure changes. It briefly increases or decreases the filament flow rate just before the print head changes speed, ensuring that the correct amount of plastic is always extruded, regardless of the print head’s velocity. It’s like having a perfectly tuned throttle and brake system for your filament.

Benefits of Pressure Advance on the MK4:

Sharper Corners and Crisper Details: Eliminates blobs and inconsistent extrusion at corners, leading to much cleaner edges.
Improved Dimensional Accuracy: Consistent extrusion means your printed parts will be closer to their intended dimensions.
Smoother Top and Bottom Layers: Prevents gaps or over-extrusion where print lines meet or begin.
Wider Material Compatibility: Helps achieve better results with a broader range of filaments.

Together, input shaper and pressure advance transform the MK4 from a solid, reliable printer into a fast, reliable, and high-quality printer. These technologies are no longer just for tinkerers using Klipper firmware. they are integrated directly into the Prusa firmware, making advanced performance accessible to everyone. This means you get the best of both worlds: Prusa’s legendary ease of use combined with cutting-edge speed and quality enhancements.
