3D printed logistics tray with ESD protection

The task
Our client, Engineed Ltd., provides engineering and 3D printing services to the Hungarian subsidiary of one of the world’s leading power electronics manufacturers.  One of the components produced in this plant at a certain stage of the manufacturing process is coated with a heat-conducting paste. The parts are placed in the pasting machine and then lifted out, and this operation is repeated in every few minutes. The parts to be pasteurised, in this case there are nine, are placed on a logistics tray, originally made of aluminium and weighing almost 4 kg. For the operators, moving this weight continuously is a demanding task over a long period of time. Engineed Ltd. task was to design a lighter logistics tray.
The challenge
While 3D printing was considered early on as a solution, the logistics tray also had to protect the electronics component from electrostatic charge. Aluminium therefore had to be replaced by a material that would provide protection against charging also. Engineed Ltd. has tried several filaments with ESD protection, but they have had difficulties printing them – warping, brittleness, no adhesion to the bed etc.

The solution

After a thorough market research, the company found the Filaticum ESD filament. Printed items are provided with a surface resistance of megaohms using this filament. The object printed from Filaticum ESD was tested by the end-user, the electronics manufacturing company and met their ESD requirements. PLA composite filament’s ease of printing was also an important factor.

Once the design was finalised, the production of the logistics tray could begin. Engineed Ltd. was working with a custom-built printer using RatRig mechanics and an opensource software.

The result

The weight of the logistics tray, 3D printed from Filaticum ESD filament, has been reduced by a third, making the work of the plant’s employees much easier. At the same time, it has delivered outstanding results in terms of production costs, which have been reduced by a sixth, and production time, which has been reduced by a tenth. All this while ensuring ESD protection.

“Printing was as easy as Filaticum promised. From a printing point of view the filament behaved exactly like a standard PLA. This minimised material wastage because we got a good result for the first time without any calibration prints.” – Ádám Korán, Electrical Engineer, Engineed Ltd. Alkalmazott filament:   Filaticum ESD
