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.
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.
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.
Equipped with 3mm thin blades, GR PRO is capable of shredding consistently every time.
After reprocessing the same material three times, the pellet size virtually identical in size with commercial virgin plastic pellets.
Moreover, no sifting is involved. Each shredding round is 6 times faster.

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.
The only desktop class plastic shredder with an intuitive 3.2-inch touchscreen interface and advanced customization options.
Polystruder GR PRO features a 3-liter hopper for shredding plastic parts up to 100mm in size. It also includes a 4.5-liter collector bin with an optical sensor that detects when the bin is full, preventing overflow and disruptions.
With its large hopper and convenient collector bin, the Polystruder GR PRO enables efficient recycling operations. The hopper accepts sizable plastic parts, while the collector bin ensures seamless collection and prevents potential issues caused by overfilling.
We have successfully conducted shredding tests using the Polystruder GR PRO plastic shredder on a diverse range of 3D printing materials, including:
If you require testing on specific materials, please don’t hesitate to get in touch with us.
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.
Yes, the blades of the Polystruder GR PRO can be replaced by the user.
The Polystruder GR PRO can shred plastic parts up to a length of 100mm.
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.
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.
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.
Polystruder GR PRO is designed to efficiently shred plastic waste. We strongly discourage the use of the Polystruder GR PRO for shredding any materials other than plastic. The device’s design and warranty are tailored exclusively to plastic shredding. Attempting to process other materials will result in the automatic voiding of the device warranty.
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.
