Resin Mixing and Dispensing

overview resins are curable liquid polymers used in digital light synthesis™ (dls™) production during printing, projected uv light cures the resin into parts, which are then post processed before printing, the resin must be mixed and dispensed into the printer cassette the principles outlined in these documents are all of the mixing and dispensing procedures used in dls production every material will use some combination of these processes as specified in their protocol reference resin protocol sheets for details about the material you are printing dental materials docid\ ljaakrscgxl6ccrigvprj elastomeric materials docid\ fp8qh0b0nmeh9r3jqtzai rigid materials docid\ xvyop41s1t9wjdnpyidv carbon printers support two types of resins one part and two part mixing and dispensing procedures vary between the two types one part resins single component remixed as specified dispensed into transfer container or cassette directly reusable when filtered (no pot life) example one part resin dispensing two part resins dual component part a and part b parts remixed separately as specified a\ b mixed during or just before dispensing into container or cassette limited pot life once mixed example two part resin dispensing before dispensing resin storage all resins have storage protocol that are critical to successful mixing and dispensing in addition to standard resin storage docid 1eza6pydo uctnoswpgie guidelines, reference resin protocol sheets docid\ qsoqbedcnabfdx656tly6 for the storage specifics about the material you are printing temperature range of storage conditions minimum shelf life and expiration dates packaging options, which dictates container types after opening conditioning requirements notes about special considerations thermal processing some resins may crystallize or freeze at lower temperatures requiring a thermal processing step, also known as incubation, prior to dispensing reference this downloadable pdf for instructions inspect cassette 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 inspection docid\ y imi7aevlyjbsatexxdb for more information
