    Mechanical properties similar to the zABS but with a manufacturing speed up to 3 times higher.

    UDP mode (Uni-Directional Peel) is the fastest mode of manufacturing of the SLASH PLUS UDP and SLASH PRO UDP 3D printers, with a printing speed of 600 mm/h. This speed, superior to the majority of SLA or DLP 3D printers, is achieved thanks to the fact that the UDP mode manufactures the piece constantly raising the build base, without the mythical sway of other resin printers. To use the UDP printing mode it is necessary to have the zUDP resin.

    The zUDP resin has good mechanical properties, enough to make pieces for artistic purposes, prototypes or other types of parts that will withstand high efforts. The zUDP presents mechanical properties similar to the zABS but with a manufacturing speed up to 3 times higher, achieving parts and prototypes in less than an hour.

    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 resin zUDP for 3D printing LED-LCD of UniZ is available in a wide range of colors to cover the different demands that a user may have. The colors currently available are: Gray and Orange. The Grey zUDP is aimed at the rapid manufacture of large volume parts with good mechanical properties. On the other hand, the Orange UDP is ideal for those users who want to manufacture small pieces with extreme precision and speed, such as figures and jewelry.

    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 zUDP 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.

    When making an impression in UDP mode, a series of specifications must be considered:

    1- UDP printing mode: Due to the unidirectional manufacturing in this way it is not possible to create pieces with the cross section completely solid. Another aspect to take into account is the manufacture of closed sections of great height since they usually present problems of resin accumulation, accumulation that can cause the breakage of the pieces during printing. It is recommended to make models with some vertical release slot.

    2- Maximum print height in the same place: To prevent overheating of the LCD screen with pieces that have a height greater than 50 mm, it is recommended to tilt the piece at a small angle. This prevents the LCD from constantly working in the same place.

    3- Maximum thickness of the wall: If the thickness of the wall of the piece is greater than 2 mm, the manufacture will reach a point where the resin will not circulate under the piece, producing the failure of the impression.

    4- Minimum wall thickness supported: A thickness of less than 1 mm is not recommended for a wall that is supported on its two lateral faces, as shown in the following image.

    If, after an impression, you do not have plans to make another one within 3 or 4 days, it is advisable to introduce the resin back into the bottle, clean the tank and the circuit. To return the resin to the bottle, simply press the button indicated in the image. Once all the resin has been extracted, the button is pressed to stop the process.

    It is important to control that the LED temperature is above 35ºC and never above 40ºC.
