ADAPTIVE PRINTING CHAMBER

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


The chamber benefits from optimum thermal insulation thanks to double insulation separated by a layer of air, drastically reducing energy loss.

Perfect thermal uniformity in the chamber

It is always much easier to obtain a uniform temperature in a chamber that is adapted and adjusted to the volume of your part being printed.

Significant reduction in energy consumption

Thanks to the compression of the chamber at the start of printing, pre-heating times are considerably reduced, reaching 200°C in less than 7 minutes. No other machine on the market offers such a rapid temperature rise for an equivalent print volume.

HIGH-SPEED LAMINAR FLOW PRINTING CHAMBER

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...



Thanks to this technology, the Qu4 HT can print parts using advanced materials such as PEEK, PEKK, PPSU and PEI (PolyEtherImide, trade name ULTEM®).

It also performs very well with more conventional materials such as ABS, PC, fibre-filled materials and metal-filled materials (MIM), such as BASF's Ultrafuse® 17-4 and 316L series, Flex, etc.

MULTI-TECHNOLOGY, MULTI-MATERIAL

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.

Dual Head
PRINTING BEDS

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.

 

Easily removable print beds

in a matter of seconds thanks to a vacuum system.

STEP CAD files of the printing bed can be supplied on request, enabling you to create your own printing beds.

Before each print, once the chamber, the print bed and the heads have reached the desired temperature, just before printing begins, the bed 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.

FILAMENT QUALITY ASSURANCE SYSTEM

The Qu4-HT can be equipped with a Filament Quality Assurance system: Qu-Control


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 Qu-Control

 

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.
