The Voron Trident 300 is an open-source DIY CoreXY FDM printer, self-assembled by engineers who want full control over their machine. With a 300×300×300 mm build volume, Klipper firmware and a panel-enclosed chamber, the Trident is a platform for precision printing with engineering polymers at speeds unattainable by a typical desktop printer.
What it is
The Trident is the third-generation CoreXY design from the Voron Design community – an open-source project where the user self-sources components, self-assembles and self-configures the machine. A closed chamber made from acrylic or aluminium panels creates a stable thermal environment mandatory for ABS, ASA, PC and CF-Nylon. Klipper firmware running on a Raspberry Pi provides access to resonance compensation (Input Shaper), Pressure Advance and virtually unlimited customisation. The result is a prosumer machine with industrial character, built entirely by its owner.

Who it’s for
- Automotive jigs and fixtures – manufacturing specialised, high-strength production templates and assembly tools capable of withstanding heavy mechanical loads using CF-Nylon (Automotive)
- Functional enclosures and housings – producing durable, heat-resistant electronic housings from ABS or ASA, leveraging the enclosed chamber to prevent warping and delamination (Consumer electronics)
- Rapid prototyping – quickly iterating designs for mechanical parts to perform fit-checks and ergonomic testing before mass production (Engineering and manufacturing)
Calibration step by step
- Calibrate the extruder Rotation Distance in Klipper by commanding 100 mm of extrusion and measuring the actual length pulled. The extruder pushes exactly the requested amount of filament, preventing under-extrusion and over-extrusion.
- Perform bed leveling and fine-tune the Z-offset to ensure the correct distance between the nozzle and the build plate. Perfect first-layer adhesion with a properly squished extrusion line – no bed adhesion failure and no elephant's foot.
- Run Input Shaper calibration using an ADXL345 accelerometer or manual ringing tower test. Active compensation of mechanical resonances – smooth walls without ghosting even at high print speeds.

Conclusion
The Voron Trident 300 is a machine for engineers who want to understand every bolt in their printer. The DIY character means total freedom of customisation, while Klipper and the panel-enclosed chamber open the door to the full spectrum of engineering polymers. Those willing to invest the effort in assembly and configuration gain a prosumer platform with performance unattainable from closed systems at the same price point.
