I do the majority of my printing in Open mode with 3rd party resins, and most of the time it is with NextDent Dental Resins. Many can work with just picking the right Resin Profile, but there are 2 specifically that can really fuck up your resin tray, and even worse your entire printer if you are not careful. The two are:
- NextDent Tray
- NextDent Gingival Mask
Both of these two resins are “very reactive” (from the engineering team at NextDent) and grossly overcure and bond to the PDMS layer, even at the lowest laser resin profile (Clear V2 and V3). When a layer bonds the the PDMS, and the printer attempts to peel, it just rips a chunk of PDMS off, therefore ruining your tray. If you let that happen a few times in a row, you could easily get resin dripping onto the optical window and possibly into the printer electronics. NextDent does not offer a solution to this, as they do not formally support their resins on the Form2 to begin with.
As far as I know, these are the only two NextDent resins that act this way - I just wanted to help prevent someone from accidentally damaging their printer!
