    Material with good mechanical properties that fits the vast majority of industrial applications.

    In the engineering sector always seeks to optimize the models that are manufactured with optimized designs and materials suitable for each application. Since UniZ have developed zENG resin, a material with good mechanical properties that fits the vast majority of applications that an industrial technician needs.

    The zENG resin has a high ductility and impact resistance without sacrificing surface quality. These advanced mechanical properties are perfect to carry out final pieces within any industry, such as: tools, conduits, housings and protections.

    The LED-LCD technology used by UniZ joins the other two technologies of 3D resin priniters already known, SLA and DLP. Its operation is similar to DLP, solidifying each layer in a single beam of light, but in the case of 3D LED-LCD printers, a set of LEDs with a wavelength of 405 nm illuminates an LCD screen that lets the beam pass through of light with the shape of the layer that is being manufactured.

    The zENG resin for 3D printing LED-LCD of UniZ is available in Amber color, a strong yellow with a certain percentage of translucency, which offers the user a vision of what happens inside a piece. This application is very common when making molds in two parts, as you can see in the following image.

    The bottle of this UV resin has a volume of 500 ml and a system of operation by suction. This system, combined with the pump of the SLASH 3D resin printer, allows to discharge and load the resin in the bottle, which is very useful when storing the resin. It is recommended to store the resin in the bottle if a time of non-operation of more than three days is estimated, for that simply press the button to load the bottle in the rolling software until the tank is without resin, place the stopper in the aeration hole and remove the bottle. To complete the cycle, it is necessary to clean the circuit with the cleaning bottle with isopropyl alcohol inside.

    Once an impression is finished, the piece should be removed from the base with the metal spatula that is included with the printer. Then the piece is immersed in IPA for 5-15 minutes to remove the uncured resin from the outer walls of the piece. After that time, pressurized air must be applied on the piece until it is completely dry. To achieve the maximum properties that the zABS resin can provide, it is necessary to cure the resin for 10 minutes in a curing center (Form Cure) having a wavelength of 405 nm.

    Before removing parts from the manufacturing base, the user must be equipped with a series of safety measures. It is recommended the use of gloves to prevent the resin and alcohol from coming into contact with the skin, it is also crucial to use safety glasses for the drops that may originate during the washing of the pieces.
