HARZ Labs is a resin manufacturer with extensive experience in chemicals, especially polymers, that develops and produces high quality materials for all types of resin 3D printer technologies (DLP/LCD, SLA, CJP and others).

Industrial Flex is a resin for LED-LCD and DLP printers that allows to obtain parts with a high tenacity. It has mechanical properties similar to polyurethane, so it has good flexibility, which makes it suitable for the manufacture of joints, shock absorbers and other engineering elements that require flexibility and toughness.

It has a breakage deformation of more than 100%, which together with its tensile strength of 13 MPa makes it one of the flexible resins with the highest mechanical resistance.

This resin also has a low shrinkage during printing of only 0.5%, which, together with its low viscosity of 0.5 - 0.8 Pa*s, makes it possible to obtain parts with good dimensional stability.

Another main advantage of Industrial Flex resin is that it can be used to add in variable proportions to other Harz Labs resins in order to reduce their brittleness and increase their elasticity*, thus being able to adjust their mechanical properties. Moreover, because this resin is available in translucent colour, it will hardly modify the shade of coloured resins (depending on the proportion used, it can dilute the colour producing less saturated colours).

*If used to add biocompatible resins, these will lose their biocompatibility.

Once an impression has been completed, the part must be removed from the manufacturing platform with the metal spatula, taking care not to damage the surface of the platform. The part is then immersed in IPA for 10 - 20 minutes, depending on the colour of the resin and the size of the part, to remove the uncured resin from the outer walls of the part. After this time, air pressure should be applied to the piece until it is completely dry. To achieve the maximum properties that HARZ Industrial Flex can provide, it is necessary to cure the resin for 30 - 60 minutes at a temperature of 40 - 60 ºC (to eliminate internal stresses) in a curing centre (Form Cure) with a wavelength of 405 nm.

Before removing the parts from the manufacturing base, the user must be equipped with a series of safety measures. The use of gloves is recommended to prevent resin and alcohol from contacting the skin. It is also crucial to wear safety glasses for any drops that may arise during the washing of the parts.
