About Piezobrush PZ3 Handheld Plasma Surface Treatment

The piezobrush PZ3 is the world’s smallest, highly effective handheld plasma treatment device.

Plasma surface treatment can improve adhesion, wetting, and cleanliness of surfaces. The piezobrush PZ3 introduces the benefits of plasma surface treatment into a convenient and lightweight handheld format, enabling improved adhesion, wetting, and cleanliness of substrates. Using Piezoelectric Direct Discharge (PDD®) Technology, which has been specially developed by Relyon Plasma, the device transforms low input voltage into high electric field strengths, dissociating and ionizing the ambient gas (normally air).

Requiring no specialist technical knowledge to operate, the piezobrush PZ3 is equipped with several built-in process control features which can be adjusted through its simple user interface, allowing users to tailor the unit to suit their applications. Building upon the previous generation of piezobrush, the PZ3 can be programmed to deliver accurate and repeatable treatment processes though its timer, which includes stopwatch, countdown, and metronome modes.

The piezobrush PZ3, which requires no additional gas supply, and generates cold-active plasma at a temperature of less than 50°C, meaning that it can be used to treat temperature-sensitive substrates.


Piezobrush PZ2-i Plasma Surface Treatment Tool for Automation
For manufacturers looking for a robot mountable plasma surface treatment tool which is capable of semi-automated or automated processes, the PZ2-i combines the effectiveness of plasma surface activation with the improved productivity and repeatability of using a robot to automate a process.

The Piezobrush allows simple germ reduction on a great variety of surfaces such as glass, plastics or metals and thus provides excellent support in effecting processes in the field of microbiology, medicine, microfluidics or food engineering.


In order to achieve optimised surface activation for different substrates, the piezobrush PZ3 has been equipped with two interchangeable modules.

piezobrush Standard Module PZ3 Standard module

The standard module has been designed for the surface treatment of non-conductive substrates such as plastics, ceramics and glass.

piezobrush Nearfield Module PZ3 Nearfield module

This nearfield module is most suitable for conductive substrates such as metals, CFRP, indium tin oxide or conductive polymers.

The device detects which module is installed in the device and automatically adjusts the parameters accordingly.



piezobrush PZ3 Display Screen

For process control of plasma treatment, the piezobrush PZ3 is equipped with various features that can be selected and modified via the user friendly display.

  • Process control
    ◊ Stopwatch: for monitoring the treatment time
    ◊ Countdown: set treatment time with automatic switch-off
    ◊ Metronome: acoustic signal after a defined treatment time
  • Power adjustment: reduction of plasma power in several increments

Increasing the strength of bondlines in 3D-printed assemblies threefold Increasing the strength of bondlines in 3D printed assemblies threefold

A significant challenge for Creabis GmbH, a 3D printing service provider, is the 3D printing of large and complex components, as normally 3D printers have maximum component dimensions of ~600mm. To make use of the advantages of 3D printing for larger components, they are printed as individual parts and then bonded together. Plasma surface treatment greatly enhances the strength of the bonds on these 3D-printed assemblies.
