Plasmics uses a modulated magnetic field to convert energy into heat. This results in the INo Trident being able to heat up and cool down much faster than a conventional nozzle.
of the Plasmics INo
& Cooldown
Heatup to 250°C
heats up to 250°C in under 4 seconds
Thats 12X faster than a High-End 50W Hotend and more than 20X faster compared to a regular 30W Hotend
The INo Trident achieves it's significantly shorter heat-up time by leveraging two features only available with induction heating. The INo Trident transfers energy quicker and the heating element requires less mass for safe operation - combined resulting in shorter wait times.
This core feature speeds up multi-material prints with frequent material changes by a factor of 5 in regular use cases and up to 20x in certain edgecases.
Cooldown to 150°C
can cool down 5X faster
compared to a regular 30W Hotend
The cooldown was measured without filament flow and without a cooling fan. Even in this worst case scenario the INo Trident performed markedly better than comparable nozzles. In a real print this results in rapid cooldown and less oozing.
questions
With which setups is the Plasmics INo Trident compatible?
Plasmics INo Trident runs with every printer with a Raspberry PI and running Klipper. It uses USB to communicate with the Control Software and needs a 24V power supply sufficient to power a regular hotend, around 60 Watts of continuous draw. Support for Duet and Marlin via SPI is in the works and will be available via software update shortly after the kickstarter delivery.
What's the point of a quick heat up when the heatbed takes a few minutes or it takes the heat chamber half an hour to get to temp..?
We believe that in the future the status quo of 3D printing will move significantly toward more complex prints. When printing with a single material with continuous extrusion - the usual use case right now - quick heat up time may not seem like such a significant advantage, in the future printing with multiple materials with a lot of extruder changes could be much faster. The main engineering goal we're trying to achieve is a higher quality extrusion even with demanding materials like PEEK & Ultem. By heating the steel nozzle itself, we offer an abrasion-resistant solution with all the temperature-flow advantages of a brass nozzle.
Could the magnetic field of the INo have an impact on inductive probes for bed mesh levelling?
Yes, and no. Because the INo Trident heats up so fast it's best to wait with heating until all measurements have been done. This way the magnetic field can't interfere with probing. When testing we never experienced any issues so this is no problem!
How is less mass better?
The INo Trident has less mass. It has less mass overall and less mass between the heating coil and the temperature sensor, this results in a much shorter time until the actual temperature reaches the sensor. This reduces the sensor lag significantly. This allows faster response to thermal fluctuations, resulting in more stable temperature and higher extrusion quality. Additionally, a lighter hotend results in less interia vibrations of the printer and increases print quality.
What is the size of Plasmics INo Trident nozzle and is it replaceable?
The nozzle we currently offer is 0.4 mm or 0.6mm and is specially optimized for induction. The temperature probe is also directly attached to the nozzle to determine the actual temperature of the material with less temperature flux delay than on regular nozzles. We are investigating if we can offer an 0.8mm inner diameter nozzle in the near future!
How is the temperature measured and how does it react to external disturbances (flow changes, cooling fans)?
The temperature is measured directly at the nozzle surface with a brazed K-type sensor. This allows us to react to changes in temperature much faster than it would be possible with a regular hotend design.
