Why choose our extruder?
A special feature of our extruder is the integrated pressure sensor, which constantly reads the pressure at the Nozzle . If, for example, the Nozzle is blocked, the machine is automatically switched off before enormous pressure builds up that could potentially damage the Extruder . This makes the recycling of fiber-reinforced materials (such as CF-PLA or GF-ABS) in particular safer.
In collaboration with SUEDSPITZE, we made the safety of the machines a priority right from the concept phase. In addition, our entire Pro bundle is CE-verified thanks to the help of SUEDSPITZE!
The QiTech Extruder is a high-quality plastic extruder in which we have combined all our experience in plastics processing over the last 4 years.
The machine is characterized by its intelligent control system and integration into our QiTech-Control software. It allows you to connect the Extruder with all other process steps ( air cooling, diameter regulation and winding) and monitor them in an app.
In cooperation with a local switch cabinet manufacturer, we equip our laboratoryExtruder with high-quality switch cabinets, because safety and performance are our top priorities.
All our machines can be found with detailed documentation on GitHub . We believe in collaboration instead of competition.
Features
Hopper
The hopper is made of stainless steel and can hold approx. 3L, but can be easily enlarged with an adapter plate.
The shape of the hopper was chosen to allow the processing of recycled granules (3-5 mm angular flakes) and to prevent "bridging" in the hopper as much as possible.
However, in order to completely exclude the jamming of individual larger flakes at the feed and thereby keep the material flow constant, a uniform shape/size of the input material is nevertheless crucial for a constant diameter during filament production.
Motor
The extruder's screw is powered by a 1.5 kW motor and allows an extrusion speed of roughly 5-8kg/h (depending on your material).
Motor specifications:
Power: 1.5 kW
Output speed: 41 rpm
Output torque: 336 Nm
Voltage: 230/400V/D/Y, 50Hz
Mass pressure sensor
The QiTech Extruder has a precise melt pressure sensor located at the end of the screw barrel. This continuously measures the pressure just before the Nozzle and as soon as excess pressure builds up, the extruder motor is switched off. With this automatic shut-off, fiber-reinforced polymers and composites, for example, can be extruded more safely.
In addition, the motor or extrusion speed is linked to the values read from the melt pressure sensor, which enables the flow rate to be as uniform as possible.
Nozzle
The blanks allow the customer to drill a suitable nozzle diameter for their specific application if required.
The nozzles are manufactured with a counterclockwise thread in order to prevent them from being screwed out by the plastic.
Additional nozzles with a short delivery time are also available at a later date.
Included in delivery:
5 steel nozzles: 1x 1.75mm 1x 3mm 3x blanks (with 1mm pre-drilled)
Heating elements
To optimize the quality of the filament produced, the QiTech Pro Extruder has 3 temperature zones that can all be individually adjusted.
In order to provide you with the longest and most uncomplicated use of our products, we can send all STL files of the 3D printed parts or ship spare parts upon request.

We cannot give a general answer to the output (e.g. in kg/h) of our extruder, as the possible output is always influenced by many other parameters, such as the type of plastic, the temperature, the size of your pellets or the nozzle diameter of the used nozzle.
As a reference value for a rough estimate: we produce about 5 kg per hour of PETG at maximum speed.
Currently 4 litres. In the future, however, we plan to offer both smaller and larger hoppers!
Included in delivery:
5 steel nozzles
1x 1.75 mm
1x 3 mm
3x Blank (with 1 mm pilot hole)
The blanks enable the customer to drill a nozzle diameter suitable for the specific application himself, if required. The nozzles are made with a left-hand thread to prevent creeping out through the plastic.
Further nozzles with short delivery times are also available from us at a later date! Just contact us for this.
The shape of the hopper was chosen to enable the processing of recyclate (3-5 mm angular granulate flakes).
However, the homogeneity of the shape/size of the input material is crucial for a constant diameter during filament production.
When using angular flakes for extrusion, there is a risk of "bridging" in the hopper, whereby individual, larger flakes jam at the inlet, so that less material is conveyed for a short time. Our Extruder has a vibrating body that can be fed into the hopper and periodically shakes up the output material.
Thanks to the intelligent control of the QiTech extruder, the extruder speed can also be continuously adjusted to ensure constant pressure and output at the Nozzle
The barrel volume is 72 cm³ , or about 85 g (PC).
The QiTech Extruder has a nitrided screw barrel (diameter 65 mm) and a through-hardened stainless steel extruder screw (diameter 25 mm)
The QiTech Extruder has already been tested with thermoplastic compounds and inorganic-filled composites.
With inorganic-filled composites, there is a risk of clogging of the Nozzle, which can result in dangerous pressure build-up and damage to the extrusion unit. We have already experienced this with our prototypeExtruder .
However, our Extruder has a pressure sensor and an automatic shut-off mechanism as a safety mechanism to prevent excessive pressure build-up. This means that even laboratory tests with inorganic-filled materials are not a safety problem.
