Resin Mixing and Dispensing

overview resin prices (including bulk prices) are available from carbon resin price lists docid\ sgkqmmrk w9 liwbjql5x (login required) the principles outlined in this course are standard resin dispensing procedures some resins may have additional special conditions to be aware of reference the materials overview docid\ qsoqbedcnabfdx656tly6 and the lab reference grids docid\ ujf4k0ny4lye74zohx1r or dental post processing grids docid\ bpjqrhgawlhchkvgppy2l for more information carbon’s resins are the raw materials from which parts are built using digital light synthesis™ (dls™) these curable liquid polymers are solidified using a series of projected uv light images resins require a secondary curing process to achieve their final mechanical properties carbon currently offers two types of resins one part and two part one part resins single component poured directly from bottle into the cassette reusable (no pot life) printed parts are cured using uv light lower mechanical strength and abrasion resistance compared to two part resins primarily used for dental applications dpr 10 and uma 90 one part resins two part resins dual component part a & part b each component is stored separately and mixed at the time of use cartridges are mixed and dispensed at the same time with cartridge dispensing docid\ fda6pra3 xhqoax3hows3 bulk resins can be mixed using bulk mixing docid\ maobjiqt6krrinh11 e8d for higher volume production limited pot life once mixed printed parts are cured using heat in an oven strong and abrasion resistant cartridge and bulk packaging for two part resins resin basics resin storage resin must be stored within a specific temperature range, which may vary per resin carbon resins are designed to be chemically altered by uv light therefore, to protect resin, we recommend storing in a dark cabinet with locking doors while you are working, you can leave resin bottles out on the bench with their caps on, and cover measuring cups and other containers with aluminum foil if you are going to leave a resin filled cassette on the bench, make sure you use a cassette cover or aluminum foil and discard the resin within the recommended time frame covering the cassette prevents the resin from solidifying with ambient uv light, which could damage the cassette you will also keep resin free of dust or debris, which could affect print quality see resin and solvent storage docid 1eza6pydo uctnoswpgie for more information failure to store resins as instructed can lead to compromised material properties and print defects resin expiration plan ahead and use all resins prior to their expiration date because they thicken with age, potentially causing print difficulties and variation in material properties and accuracy carbon includes expiration dates on resin bottle labels to manage inventory check the certificate of conformity for the latest expiration information expiration dates on the bottles are the earliest possible expiration at the time of shipping and may be extended from time to time please check the certificate of conformity to see if your resin bottle has a later expiration date the latest minimum shelf life is at least 6 months from resin shipping date for most carbon resins the minimum shelf life is 3 months for dpr 10 epu 44 epu 46 black part a epu pro 70 expand bottle one part resin | cartridge two part resin inspect the cassette before dispensing cassette inspection is critical to ensure the window is in proper condition for printing, to maintain print quality and avoid permanent damage to the cassette always check the cassette before dispensing resin see cassette care docid\ y imi7aevlyjbsatexxdb for more information
