Gluing, painting and 3D printing are only successful if the materials involved adhere well to one another. However, there are always problematic combinations that are difficult to combine. One example is 3D printing with ABS filaments. Since ABS expands or shrinks significantly when the temperature changes, adhesion to the printing plate is difficult even during printing. The result: warping, i.e. the detachment of the object from the print bed during the printing process.
A treatment of the print bed surface can help: With a cold plasma (ionized gas) generated by high voltage, additional energy is applied to the surface, which in many cases increases the adhesion.
Such treatment is with that Plasma handheld device PZ3 from Relyon Plasma Possible anywhere: The small device works with air as the working gas. One Piezo Transformer generates the required high voltage, with the help of which the air ionizes and thus becomes a plasma. The PZ3 only has to be guided over the corresponding surface and it activates it. The performance of the device can be reduced by up to 40 percent for sensitive surfaces.
Dem Device set in a sturdy plastic case At a price of 2400 euros, two exchangeable modules are included in addition to a plug-in power supply, one each for electrically conductive and non-conductive surfaces. The manufacturer can also provide rental equipment on request.
Operation is via pushbuttons, a color display shows the settings.
During tests in the editorial office, the warping of ABS could be significantly reduced. However, it also became apparent that when working with the PZ3, an extractor device is urgently recommended that extracts the ozone generated in large quantities while still near the nozzle of the device.
