QUALUP SAS

Qu4-HT is a high temperature 3D printer designed to work with high-performance materials like Polycarbonate (PC), PEI 9085, PEI 1010, PEKK, PEAK, PPSU. At the same time, it offers a range of exceptional features

Large print volume: 400 x 400 x 400 mm, with other sizes available on request (400 x 400 x 500mm & 500 x 500 x 500mm)

Ultra fast heating time: the adaptive chamber ensures minimal warm-up time, so the printjobs start quickly (3 min. heating time for Polycarbonate (140°C) and less than 10 min. for PI or TPI (245°C))

High temperature printhead camera: a camera in a high-temperature enclosure which offers exceptional image quality and nozzle visualization.

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 printed parts.

Working with high-performance materials requires the use of very high processing temperatures.

While power consumption is relatively low for melting materials themselves, heating the build chamber can significantly increase energy consumption.

Heat only the volume you need to print

We approach this in a way that is both more sustainable and cost-efficient. We heat only the essential area of the build chamber needed for printing.

This drastically reduces power consumption and operating costs, and additionally speeds up the process significantly:
    • 3 min. heating time for Polycarbonate (140°C)
    • less than 5 min. for PEI 9085 (175°C)
    • 7 min. for PEI 1010 (220°C)
    • less than 10 min. for PI or TPI (245°C).

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.

And 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.

By default QU4-HT offers build volume of: 400 x 400 x 400mm (64 litres).

Our 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.

We also offer others sizes of build area available on request:
• 400 x 400 x 500mm
• 500 x 500 x 500mm.

With the QU4-HT, you’re not limited to filament. Thanks to the easily interchangeable print heads, you can switch from filament to pellet, as well as thermosets and paste materials, within minutes. The machine recognizes the installed head and configures itself for optimal use.

The print heads are liquid-cooled. A water pump circulates 500 liters of liquid per hour through the head, maintaining an ideal temperature in the cold zone of the head. The cooling liquid is then cooled by a ventilated radiator.

With this system, the water temperature never exceeds 45°C, even during several hours of printing at extrusion temperatures up to 420°C.

QU4-HT has a whole range of one-of-a-kind, unique features:

• High-Speed laminar flow printing chamber - thanks to this technology, the Qu4 HT can print parts using advanced materials such as PEEK, PEKK, PPSU and PEI

• High resolution, Hi-temperature head camera - this camera offers exceptional image quality and nozzle visualization; its resistance to high temperatures enables precise, real-time observations of the printing process and nozzle path, giving users unprecedented control

• Thermal imaging camera - provides a global thermal vision of the chamber, updated more than 5 times per second

• Wide range of printing beds

• Filament Quality Assurance system - measures filament diameter continuously and compensates for variations in volume during printing
