Plastic shredding with the power of AI

Revolutionize plastic shredding for additive manufacturing with Polystruder GR PRO and its innovative ShredAI algorithm. Developed in-house, this unique shredding algorithm detects the material properties and automatically adjusts the motor speed and power in real-time, ensuring efficient and effective shredding every time.

The power of the ultra-quiet 300W brushless DC motor with a 90:1 gear ratio delivers an impressive 40Nm crushing power, making shredding even the toughest plastics a breeze.

Polystruder GR PRO boasts 19 stainless steel double-sided blades that cut through the plastic in both directions, doubling the blade life and reducing both shredding time and maintenance costs. With unique 3 different blade profiles, this shredder can handle thick materials, up to solid 25mm 3d printed plastic objects.

Connect and manage your shredder remotely with the Polystruder GR PRO's 32-bit Dual Core MCU, Wi-Fi connectivity and the only desktop class plastic shredder with intuitive 3.2-inch touchscreen interface.

With 3 liters of hopper and 4.5 liters of collector bin capacity, the Polystruder GR PRO can handle a large amount of plastic shredding, making it the perfect tool for industrial and personal use alike.

The Polystruder GR PRO doesn't just shred plastic by turning the motor, it does more than that!

It features an in-house built custom shredding algorithm called ShredAI, which reads data from its sensors to detect the material hardness. This allows it to determine the optimal shredding speed and adjust the motor speed and power limit in real-time.

It also includes numerous safety features that automatically stop the shredding process if a jam is detected, no material is present, the bin is full, or the hopper door is open during operation.

19 Stainless steel blades​

The Polystruder GR PRO stands out as the only single shaft plastic shredder available with a unique double-sided cutting blade design, resulting in a blade life that is twice as long as that of other plastic shredders.​

Additionally, the Polystruder GR PRO allows for faster shredding speeds of up to 5kg per hour, while also lowering maintenance costs and reducing overall downtime.

3 blade profiles​

The unique blade profiles of the Polystruder GR PRO enable it to cut through thick materials, including solid 25mm plastic objects.

Three large blades shreds large plastic materials and decrease their overall dimensions for easier processing. Two medium blades aid in reducing both large and medium-sized plastic pieces to even smaller sizes.

Finally 14 small blades shreds through the remaining plastic efficiently and reduce the final piece size down to 3mm.

Powerful 300W BLDC Motor

Thanks to its powerful 300W brushless DC motor with a 90:1 gear box, the Polystruder GR PRO can process any plastic without interruptions.

Moreover, it is equipped with built-in overcurrent, overvoltage, temperature limit, and jam detection features, which provide protection to the motor and gearbox, guarding against potential damage.

Best in Class Electronics

The Polystruder GR PRO features a powerful 32-bit Dual Core MCU with Wi-Fi connectivity.

With OTA updates, the product can be easily updated with the latest firmware and software for optimal performance.

It is equipped with five sensors that constantly check the status of the machine.

For added security, a safety relay for the motor is included, preventing accidental motor startup and enhancing the product's safety features.

It is also the only desktop class plastic shredder with an intuitive 3.2-inch touchscreen interface and advanced customization options.

Large material volume

Polystruder GR PRO has 3 liters of hopper and 4.5 liters of collector bin capacity.

Hopper can accept up to 100mm large plastic parts that can be shredded. Collector bin has an optical sensor that checks if the bin is full.


What is the average shredding speed of the Polystruder GR PRO?

The shredding speed of the Polystruder GR PRO depends on multiple factors, including the material type, thickness, size, motor speed, and more. However, when shredding objects that are 30mm in size, made of PLA with a 1.6mm wall thickness and 20% infill, the Polystruder GR PRO has a shredding capacity of approximately 3kg per hour.

Are the shredding blades user replaceable?

Yes, the blades of the Polystruder GR PRO can be replaced by the user.

What is the maximum size of plastic parts that the Polystruder GR PRO can shred?

The Polystruder GR PRO can shred plastic parts up to a length of 100mm.

Are there any limitations on the types of plastic that the Polystruder GR PRO can accept?

There are virtually no limitations on the types of plastic that the Polystruder GR PRO can accept. However, it's important to note that certain plastics with harsh additives, such as carbon fiber, wood, steel, and similar materials, can significantly reduce the lifespan of the shredding blades.

How much power does the Polystruder GR PRO consume?

The Polystruder GR PRO features a highly efficient brushless DC motor with a maximum power draw capacity of 300W. However, on average, it consumes only 150W per hour.

How does ShredAI work?

ShredAI is an in-house developed custom shredding algorithm that operates by continuously monitoring real-time data such as motor power consumption, blade direction changes, and temperature. Based on this information, ShredAI makes decisions to automatically adjust the motor speed, optimizing the shredding speed for optimal performance.

Is it possible to shred other materials other than plastic?

We designed the Polystruder GR PRO to efficiently shred plastic waste. We do not recommend to shred any other material besides plastic. Using it to shred other material besides plastic will void the device warrantly.

What is the average dimensions of shredded plastic parts?

Average shredded plastic pieces varies between 3mm to 5mm. However we recommend shredding at least 2 times to achieve the more granular piece size. There could be some instances where some thin parts that as big as 20mm can fall in between blade spacers inside the collector bin.
