FluidANT Frequently Asked Questions
What is FluidANT?
FluidANT is print technology which enables you to produce high performance antennas, sensors and electrical circuits on 3D surfaces using conductive ink. Process suits also to printing dielectric materials and to other applications in which the high speed, excellent accuracy and precise deposition rate are important.
FluidANT consists of the FluidWRITER printer and related CAM design software for the print work programming.
What are the biggest benefits of FluidANT?
With FluidANT you can print on 3D part made from commonly available material with good mechanical properties and wide choice of colors. The print system enables significant reduction in prototyping and versioning time. It also opens a new industrial design and integration options and the printing locate next to the device assembly without long process chain or complex logistics.
How does FluidANT compare to other printing technologies?
Other existing printing techniques, like screen and pad printing, are either limited to 2D applications or use, like inkjet or aerosol jet, high cost nanoparticle inks.
Unlike in traditional dispensing systems, in FluidWRITER printers the printhead operation is synchronized in real time to actual motion which makes it capable to very precise dosing in high speeds. Printed line width and thickness remain stable in all situations. Unique digital 3D offset setting together with advanced control SW enables accurate printing on rotary three dimensional surface.
What substrates can be used?
FluidANT can be applied on normal resins with good mechanical properties and wide choice of colors, resins do not need any additional additives. The most common are polycarbonate grades. Polyamide grades are used with care on molding parameters. Also wide range of other resins can be used.
What type of inks can be used?
In creating antenna patterns and conductive traces the FluidANT printing uses high viscosity micron particle silver inks. Benefits of micron particle inks are low cost and good conductivity. It is always recommended to verify in advance the compatibility of an ink and a substrate securing e.g. good adhesion.
What ink drying temperatures are used?
Higher ink drying temperature produces better conductivity, therefore the drying is typically set as high as possible for the used resin material. Typical drying temperature for polycarbonate is about 100C. Maximum drying temperature for polymer based inks is typically around 200C and minimum drying temperature around 70C. Lower conductivity due to low temperature drying can typically be compensated to some extend by longer drying time.
