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.
Chamber at start of printing
Chamber at the end of printing
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...

Air flow in the chamber
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.

LARGE PRINT VOLUME

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.

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.

 

Tête Double

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.

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.

AUTO CALIBRATION AT TEMPERATURE

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.

QUALITY ASSURANCE SYSTEM

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.

THERMAL IMAGING CAMERA

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.

PRINT DATA RECORDING

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.

CONNECTED OBJECTS

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.

PRINT HEADS MAINTAINABLE OUTSIDE THE MACHINE

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.

MODULAR DESIGN FOR SIMPLIFIED MAINTENANCE

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.

> Quelles garanties puis-je avoir sur la pérennité de votre entreprise ?
Nous sommes une TPE française et une petite équipe de passionnés, nous concevons et fabriquons en France des imprimantes 3D depuis 2011, les premières machines ont été livrées au premier semestre 2013, il y a donc 9 ans maintenant. Voici quelques informations qui pourraient vous sécuriser et tranquilliser :
– Nous sommes financé sur nos fonds propres et ne sommes pas dépendants d’actionnaires qui pourraient décider de changer de stratégie ou de politique. La presque totalité des bénéfices est ré-injectée dans la R&D.
– Les décisions techniques ou marketing sont prises par une petite équipe de personnes expérimentées qui partagent toutes la même devise : Fabriquer des imprimantes 3D FFF avec le meilleur de la technologie actuelle et au meilleur rapport qualité/prix possible : «Nous ne parlons pas de gadgets, de fioritures, ni de prétentions exagérées, nous parlons de qualité d’impression, de conception robuste et de performance !»
– Nos frais fixes sont réduits au strict minimum, la production étant réalisée par des partenaires spécialisés équipés de machines CNC de dernière génération. Ceci nous permet de supporter facilement les pics ou ralentissements de commandes sans trop influencer notre trésorerie.
– Nous avons vu apparaître puis disparaître des dizaines et des dizaines de sociétés fabriquant des imprimantes 3D ! Nous avons toujours gardé la même ligne de conduite : fabriquer des machines à la pointe de la technologie, sans tenir compte des modes ou tendances, c’est sûrement ce qui fait que nous sommes toujours là et heureux de ce choix…
– Pour finir, nous nous engageons à fournir à nos clients les fichiers STEP des machines, nomenclatures et la liste des principaux fournisseurs, en cas de besoin.
