QU3 high-temperature 3D printer

Our high-temperature 3D printer is equipped with a 270°C heated chamber that maintains a constant temperature to minimise warping, shrinking and deformation.


The chamber temperature can be adjusted from 30°C to 270°C to allow for heat treatments during or after printing.


Thanks to this technology, the Qu3 HT can print parts with advanced materials such as PEEK, PEKK, PPSU and PEI (PolyEtherImide, trade name ULTEM®).


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

QU3 high temperature 3D printer with liquid cooled dual head

Our high-temperature 3D printer is equipped with print heads that can be changed in minutes, allowing great flexibility in the choice of materials.


The heads can be supplied for different types of materials, such as filaments, high temperature filaments, pellets, high temperature pellets, thermosets, pasty materials, carbon filled materials, fibreglass, etc.


The machine recognises the installed head and self-configures for optimum use.


Save energy... Why heat a 340mm high chamber if your part is only 150mm high?

The Qu3 HT only heats the volume needed to print your part, with a chamber that automatically and gradually adjusts to the height of the print.


Accelerated pre-heating

By compressing the chamber at the start of the print, pre-heating times are dramatically reduced, reaching 200°C in under 7 minutes. No other machine on the market has such a fast heat-up time for the same print volume.


The mechanical components are completely isolated from the 270°C heating zone to minimise thermal expansion.


All elements of the chamber can withstand a continuous temperature of 270°C, while elements that cannot withstand these temperatures are isolated or separated.


The electronic part is located at the back of the machine and is ventilated to ensure optimum thermal protection and long life.

QU3 high temperature 3D printer heated print bed

In addition to its high operating temperature, the Qu3 HT has different 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 lower temperature materials.


Metal or ceramic beds can be used for extreme temperatures.


The print bed is easily removed in seconds using a vacuum system.


In addition, STEP or DXF CAD files of the print bed can be supplied on request allowing you to design your own print beds.

The Qu3 HT printheads are cooled by a liquid cooling system.


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 in turn cooled by a ventilated radiator.


The heads are equipped with a system of self-sealing connectors for connection and disconnection, making maintenance easier and minimising the risk of fluid leaks. With this system, the water temperature never exceeds 45°C for several hours of printing at an extrusion temperature of up to 420°C.


By choosing a liquid cooled head, you can therefore benefit from more stable, reliable and efficient printing on a wide range of materials, while ensuring the longevity of your machine through easy maintenance.


Each time you start a print job, the Qu3-HT records all the print parameters, such as speeds, head, chamber and bed temperatures, material flow rates, filament diameter, volume compensation sent, etc.


The generated files are Excel compatible, allowing you to retrieve the data you need and check that the print has been completed correctly.

Qu3 with Filament Control

The Qu3-HT can be equipped with a Quality Assurance system that provides continuous Filament Measurement and Volumetric Compensation for variations during printing.


This system compensates for variations in filament diameter to ensure part quality and reproducibility.


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, PPSU, some manufacturers even claim tolerances of +/-0.10mm, which means the filament can vary by 24% by volume!


With the Qu3-HT's Filament Control, you can be sure that the quality of your parts will be the same regardless of filament variations. This feature ensures the reproducibility of 3D printed parts.


The Qu3-HT generates a complete html print report for each print, which contains all print and temperature parameters, as well as all filament diameter and ovality measurements (with an accuracy of 0.8µm) and volume compensations sent to the machine.

QU3 high temperature 3D printer seen with thermal camera

The Qu3-HT offers a FLIR thermal camera option.


This camera provides 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.



The Qu3-HT allows the addition of dozens of IoT, such as sensors, cameras, etc.


These objects can interact with the machine or not, depending on your needs and specifications.

QU3 Test bench

As an option, a pre-setting bench can be used to perform all the common tasks on a printhead, such as warm-up, flow calibration, bed probe calibration, cleaning and unclogging of the head, among others.


The bench is easy to use, a head can be installed in less than two minutes and it is able to automatically recognise the installed head and configure itself accordingly.


The Qu3-HT has been designed to facilitate maintenance and minimise machine downtime.


By using standard off-the-shelf components, maintenance is simplified and wear parts are easily accessible.


The printheads can be removed in minutes, allowing quick and accurate maintenance either on a preset bench or with the head extension supplied with the machine.


The high temperature heaters in the chamber can be replaced in less than 5 minutes using four screws and two connectors.


The thermal camera can be removed in three screws, while the vacuum pump can be removed in just four screws and six minutes.

> What guarantees can I have about the sustainability of your business?
We are a French TPE and a small team of enthusiasts, we have been designing and manufacturing 3D printers in France since 2011, the first machines were delivered in the first half of 2013, so 10 years ago now.
- We are equity funded and not dependent on shareholders who may decide to change strategy or policy. Almost all profits are re-injected into R&D.
- Technical or marketing decisions are made by a small team of experienced people who all share the same motto: Making FFF 3D printers with the best of current technology and at the best possible price/quality ratio: "We are not talking about gimmicks, frills, or exaggerated claims, we are talking about print quality, robust design and performance!"
- Our fixed costs are kept to a minimum, with production being carried out by specialist partners equipped with the latest CNC machines. This allows us to easily cope with peaks or slumps in orders without affecting our cash flow too much.
- We have seen dozens and dozens of companies manufacturing 3D printers appear and disappear! We have always kept the same line of conduct: to manufacture machines at the cutting edge of technology, regardless of fashions or trends, which is surely why we are still here and happy with this choice...
- Finally, in case we have to close the company, we commit ourselves to provide our customers with STEP files of the machines, bills of material and the list of the main suppliers.
> Was everything designed and created from scratch?
We always try to use standard elements to reduce costs, for example we use Dyze Design extruders.

But the design and production of the :
-Tilt system for filament head
-Print bed sensing system.
-Heating system.
-Integrated thermal camera.
-Adaptive chamber

Are exclusive to the Qu3-HT
> What firmware are you using?
We use an adapted version of RepRap Firmware 3
> Where are the machines made?
Our machines are designed near Mâcon (France) and manufactured mainly in Burgundy. Mechanical machining, electrical cabinets, painting, laser cutting and bending are all done in the Mâconnaise region.
Of course there are several components coming from China (power supplies, electronic components...). To be honest, it is no longer possible to fight over certain components, it is enough to select them well.
The machines are entirely assembled, wired and calibrated in France.
More than 85% of the value of the machine is made in France.

We offer efficient and understandable technical support for our customers.


We know that 3D printing of high temperature polymers is not always without its setbacks.


We design and manufacture the machines, we provide "first class"  technical support, carried out by a technician specialised in high-temperature polymer printing who has participated in the design of the machine and knows it in detail.


Our technical support service is available by email in English and French to answer all your questions.


For customers with annual maintenance or whose machine is under warranty, we also offer a remote control of the machine for fast and efficient technical support.


We are committed to maintaining and supporting our machines so that you can continue to print with peace of mind.


We provide technical support for all older machines (SpiderBot, ABSolute 2) within the limits of technical possibilities for very old machines.

In all cases, please contact us by email at support[at]qualup.com, we will do our best...


Our motto:

"It's not about gimmicks, frills, or exaggerated claims... It's about quality, robust engineering and performance."

Our approach to machine design is focused on simplicity and quality.

We believe that machines should be designed to perform their primary function reliably and efficiently, rather than trying to impress with gimmicks or unnecessary features.


Design philosophy:

We always seek to maximise the use of standard components, which we often divert from their primary function to reduce costs.

Where necessary, we adapt or modify these components to meet specific requirements, such as temperature resistance.

We also favour laser cutting and bending techniques over machining, as this can significantly reduce costs. Our design always breaks down the functions of the bent parts and uses the precision of the laser for the part joints, never the less precise bent area which is only used to provide strength and rigidity.

We are pragmatic and have a quality-oriented approach. We do not aim to achieve over-quality, but rather to ensure optimum quality for our customers.

We also apply technical safety margins on all critical components such as axes, motors, heads, etc.

Finally, the design of our machines is always the result of their intrinsic design.

We use a minimalist approach that may not appeal to everyone, but it simplifies operations and reduces costs without sacrificing quality.
