Visco Tool

Screw driven for high viscosity inks.

The principle of operation in Visco Tool print head is based on the endless piston principle belonging to the group of rotating displacement pumps. The heated version comes with a heating function enabling a constant temperature from RT to +66 °C throughout the print head and the syringe barrel containing the printable material. The dead volume is slightly higher than that of the Rotary Tool from the same family, but the maximum output force is much higher.

Visco Tool can be used to print lines and dots of various viscous fluids and pastes, such as bioinks, biopaste, silicone, acrylate, epoxy resin, light-curing adhesives, waxes, ceramics, and abrasive pastes. Especially suitable for shear-sensitive fluids with high viscosity and fillers inside as the dosing principle enables gentle treatment due to the low shear stress and the low pressure. The printed product remains homogeneous due to compression-free conveyance. Compatibility with standard parts such as Luer lock needles and syringe barrels makes this dispensing head a cost-effective solution.
