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.

Chamber heated to 270°C

QU3 imprimante 3D haute temperature banc de prereglage

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...

Adaptive Chamber

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.

Print beds

QU3 imprimante 3D haute temperature lit d impression chauffant

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.

Liquid-cooled head

QU3 imprimante 3D haute temperature tête double a refroidissement liquide

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.

Unique Professional Features...

Part Quality Assurance System with continuous filament measurement and volume compensation of variations during printing

Qu3 équipée d'un Filament Control

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.

Pre-setting bench

QU3 imprimante 3D haute temperature banc de prereglage

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.

Thermal Camera and Connected Objects (IoT)

QU3 imprimante 3D haute temperature vue en camera thermique

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.


Connected Objects

It is possible to add dozens of connected objects (sensors, cameras, ...) interacting or not with the machine.

Modular design for easy maintenance

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:

  • Extract the printheads from the machine in a few minutes, perform maintenance either on a preset bench or with the Head extension cable (the hydraulic liquid cooling connectors are self-sealing) supplied with the machine. You can warm up the head, extrude, disassemble nozzles and probes quietly at your desk, without stress.
  • Replace a High Temperature Chamber Heater in less than 5 minutes (4 screws, 2 connectors)
  • Extract the vacuum pump by 4 screws and in 6 min.
  • Extract a Camera or Infrared camera  module by 3 screws

> What products are available?
Currently only the Qu3 HT is in production.
The other products are at the end of their life, but their after sales service is still assured.
If you need technical support for your SpiderBot, please contact us.
> How long have you been in business?
Our company was founded in 2004, and we have been working on 3D printing since 2011.
> What are your innovations?
If you have been familiar with 3D printing for several years, you may have noticed that we have always been innovative and were the first or among the first to market a production machine with :

- An all-metal extrusion head (2013 - at the same time, E3D released its first all-metal heads)
- A dual drive extruder (DualDrive in 2013, now widely used by the leading manufacturers of high end extruders: Dyze, Bondtech... )
- Enclosed and hooded enclosure (2013 - everyone is getting there)
- 3 spheres and magnetic ball joints system (2014),
- Machine whose geometry was not achieved by assembling components but by precision laser cutting.
- Heated chamber (2014 - essential for printing technical materials...)
- Double swivel head (2014 - the unused nozzle no longer touches the printed part)

> 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 9 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 :
-Liquid cooled head.
-Liquid cooled double extrusion 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 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 provide technical support by email only (French and English).


Customers who have subscribed to annual maintenance or whose machine is under warranty can receive technical support directly by remote control of the machine.


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