The Qu3 HT can be supplied with various types of printheads:
⦁ High Temperature Filaments,
⦁ High Temperatures Pellets,
⦁ Paste Materials,
⦁ Carbon-filled Materials, Fiberglass...
The heads are interchangeable within minutes, the machine recognises the installed head and self-configures.
The heated chamber maintains the temperature of the part up to 270°C, reducing warping, shrinkage and deformation to a minimum. The temperature of the chamber is adjustable from 30°C to 270°C, allowing you not only to print but also to carry out heat treatments during or at the end of your prints (annealing, crystallisation, stress release...).
It is possible to carry out annealing curves at the end of a print with linear cooling, by step, etc...
This technology allows the Qu3 HT to print large technical parts with materials such as PEEK, PEKK, PPSU or PEI (PolyEtherImide, trade name ULTEM®).
While remaining very efficient with more conventional consumables such as ABS, PETG, PC, fibre-filled materials, metal-filled materials, Flex...
The chamber automatically adjusts to the size of the part during printing.
The mechanical components are completely isolated from the 270°C heating zone. Thermal expansion of components exposed to extreme temperatures is reduced to a minimum.
All elements in the chamber are resistant to 270°C continuously. All elements not resistant to this temperature are isolated and/or separated.
The electronic part, located on the rear side of the machine, is isolated from the machine and ventilated, which guarantees its thermal protection and an optimum life span.
The printheads are liquid cooled and integrated in a stainless steel housing, protecting them from the temperature. A 240mm radiator ensures that the liquid is kept at a low temperature.
Different print beds can be used:
⦁ PEEK: ultimate material resistant to 250°C continuously, the best compromise for printing PEEK and PEKK
⦁ PEI: material used in aeronautics and medical, PEI ensures perfect adhesion of the part during the printing phase and allows easy take-off at room temperature. No more welded parts on the print bed, no more parts coming off the bed. This print bed is used for temperatures from 60° to 180°C
⦁ Metal or Ceramic: Copper, Aluminium or ceramic for extreme temperatures
⦁ The print bed is removable in seconds, secured by a vacuum system.
⦁ STEP or DXF CAD files of the print bed are provided on request.
The printheads are liquid cooled, the liquid temperature never exceeding 45°C for several hours of printing at 420°C extrusion temperature.
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 coolant is cooled by a ventilated radiator.
A system of self-sealing connectors, which are self-sealing when plugged in and unplugged, allows for easy maintenance of the entire head, while protecting against the risk of fluid leakage.
Compensating for filament diameter variations to ensure part quality and reproducibility...
The manufacturing tolerances of filaments generally vary by +/-0.05mm, which in reality gives a 12% variation in volume between the maximum and minimum tolerances.
For technical filaments: PEEK, PEKK, PEI, PPSU... Some manufacturers even announce tolerances of +/- 0.10mm, the filament can therefore vary by 24% in volume!
With a Qu3-HT equipped with Filament Control, you can be sure that the quality of your parts will be the same regardless of filament variations.
This makes it easy to ensure the reproducibility of 3D printed parts. Once you have achieved the desired part properties in the pilot phase, you can be sure that subsequent parts will be absolutely identical.
The Qu3 HT generates a full print report for each print. This report contains all print and temperature parameters, as well as all filament diameter (to an accuracy of 0.8µm), ovality measurements and volume compensations sent to the machine.
This bench allows all the common operations to be carried out on a print head:
⦁ Heating of the heads
⦁ Calibration of the flow
⦁ Calibration of the bed sensor
⦁ Cleaning and/or unclogging the head
A head is installed in less than 2 minutes on the Bench and the Bench recognises the installed head and configures itself automatically.
A FLIR thermal camera is available as an option. You have a global thermal view of the chamber, updated more than 5 times per second. Temperature measurement tools allow you to measure up to 5 points simultaneously. The thermal camera can be accessed from any PC connected to your network.
It is possible to add dozens of connected objects (sensors, cameras, ...) interacting or not with the machine.
Machine downtime for maintenance is often a source of significant financial loss. The Qu3-HT has been designed in modules to allow simplified and economical maintenance.
When designing a product, we systematically look at whether it is possible to use standard commercial products, even if it means using them as a basis to modify and improve them and then integrating them into an independent module.
This saves a lot of time and money on wearing parts and spare parts.
The modular design allows for example to:
