Visit us and discover the Qu4-HT at formnext , Hall 12.1 Stand A15 from 7 to 10 November 2023 - Frankfurt - Germany
Heat only the volume you need to print.
The Qu4 HT heats only the volume needed to print your parts, with a chamber that adjusts automatically and progressively according to the height of the print. .
Double thermal insulation
Laminar airflow printing chamber up to 300°C
The hyper-ventilated chamber uses a unique technology to propel a stream of hot air into the chamber.
Renewed almost 2 times a second, this hot air ensures perfect thermal uniformity of your parts.
No more areas that are too hot or areas that warp...
400 x 400 x 350mm : 56 LITRES
With a print area of 400x400x350mm, this machine is suitable for producing large parts or printing several objects in a single session. This capacity offers users great flexibility and increased efficiency, minimising repeated print cycles.
Liquid-cooled printheads.
A water pump circulates 500 litres of liquid per hour through the head, ensuring an ideal temperature in the cold zone of the head. The cooling liquid is in turn cooled by a ventilated radiator.
With this system, the water temperature never exceeds 45°C for printing lasting several hours at an extrusion temperature of up to 420°C.
Interchangeable print heads in just a few minutes,
allowing great flexibility in the choice of materials.
The machine recognises the head installed and configures itself for optimum use.
Filaments, Pellets...
Heads can be supplied for different types of material, such as filaments, high-temperature filaments, pellets, high-temperature pellets, thermosets, pasty materials, etc.
Heads fitted with a system of self-sealing watertight connectors
during connection and disconnection, facilitating maintenance while minimising the risk of liquid leaks.
By opting for a liquid-cooled head, you can benefit from more stable, reliable and efficient printing on a wide range of materials, while guaranteeing the longevity of your machine thanks to easy maintenance.
The Qu4 HT comes with a range of print beds
to suit your specific needs.
The PEEK print bed is the optimal choice for printing materials such as PEEK and PEKK, while the PEI bed is ideal for printing materials at lower temperatures. Metal or Glass beds can be used for extreme temperatures.
Before each print, once the chamber, the print bed and the heads have reached the desired temperature, just before printing begins, the sensor is auto-calibrated. This step precisely determines the distance between the sensor and the nozzle.
Following this probe calibration, the bed also undergoes a self-calibration, including a 3D mapping of its surface.
This procedure ensures the optimum position of the printing nozzles, guaranteeing a perfect first layer.
This procedure is repeated for each print run.
The Qu4-HT can be equipped with a Quality Assurance system: QuControl
which measures filament diameter continuously and compensates for variations in volume during printing.
Filament manufacturing tolerances generally vary by +/-0.05mm, which in reality gives a 12% variation in volume between the maximum and minimum tolerances. For technical filaments such as PEEK, PEKK, PEI and PPSU, some manufacturers even claim tolerances of +/-0.10mm, which means that the filament can vary by 24% in volume!
This system makes it possible to compensate "live" for variations in filament diameter.
Thanks to QuControl
you can be sure that the quality of your parts will be identical, whatever the variations in the filament. This feature guarantees the reproducibility of 3D printed parts.
The Qu4-HT generates a complete print report for each print, containing all the print and temperature parameters, as well as all the filament diameter and ovality measurements (with an accuracy of 0.8µm) and the volume compensations sent to the machine.
The Qu4-HT offers an optional FLIR thermal imaging camera.
This camera provides a global thermal vision of the chamber, updated more than 5 times per second.
Temperature measurement tools
enable you to measure up to 4 points simultaneously.
The thermal camera can be accessed from any PC connected to your network.
For each print, the Qu4-HT records all the print parameters
such as speeds, head, chamber and bed temperatures, material flow rates, and so on.
The files generated are Excel-compatible, so you can retrieve the data you need and check that the print has been completed correctly.
A machine designed to be connected
Our machine is adapted to current technological developments. It has been specifically designed to accommodate the addition of multiple connected objects, enriching its potential and versatility. Whether it's sensors to monitor specific variables, cameras for surveillance or visual analysis, or other devices, our machine is ready to integrate into an advanced technological ecosystem.
Flexibility of Interaction:
Added connected objects can either operate autonomously or interact directly with the machine. This flexibility allows you to adjust the configuration according to your precise requirements. So, depending on your needs and specifications, you have the freedom to define the degree of integration and interaction of each component.
Each machine is supplied with a specially designed extension lead.
This extension has been designed to allow you to work on the extrusion heads outside the machine.
Safe warm-up: You can warm up the heads outside the machine.
Easy maintenance: Regular checks and repairs are child's play. With the extruder head detached, you have easy access to every component. No more twisting and turning to access difficult areas: everything is within easy reach.
Precise calibration: Make your adjustments and calibrate the extrusion rate in a comfortable working environment.
Optimised working environment: Thanks to this extension, you can now carry out these tasks from the comfort of your desk, next to the machine.
So, depending on your needs and specifications, you have the freedom to define the degree of integration and interaction of each component.
The Qu4-HT has been designed to facilitate maintenance and minimise machine downtime.
By using as many standard off-the-shelf components as possible that can be adapted to thermal constraints, maintenance is simplified and wear parts are easily accessible.
The printheads can be removed in a matter of minutes, enabling fast and accurate maintenance using the head extension supplied with the machine.
High-temperature chamber heaters are accessible from the side and can be replaced in less than 5 minutes.
The thermal camera can be extracted with three screws, while the vacuum pump can be removed in just a few minutes.
