Awful

Rated with 1 out of 5 stars.

I thought this could help replace several different small casting molds I've been using, to try and speed up production times for certain products.

However, this is absolutely useless stuff. I've ended up wasting half the bottle testing about 30 different prints, varying exposure times, lift speeds, base layers, base exposure, curing times, curing methods, curing temps etc. I'm printing on an Elegoo Mars in preparation testing for production on a Saturn in 2 weeks, so I used the suggested Anycubic Photon settings as a benchmark (nearly identical printers) and that failed. I ended up ruining FEP sheets due to this not wanting to stick the build plate in most configurations.

I slowly worked my way up to some settings that wouldn't fail mid print. I finally got myself some working examples from various exposure settings. I tested multiple cure methods, starting with their recommended times and temps and going from there.

After getting several working examples, it appears that the technical data for this resin just isn't correct in the slightest. This is definitely not 85A equivalent. It feels closer to 95A, but with absolutely useless strength. It's nowhere near as flexible as it advertised, and the strength is laughable. A baby could tear this stuff. I did elongation tests after a maximum 3 day settle and my best result managed 3%. Equivalent casted parts held in excess of 15kg and elongation of 50-60%; this resin couldn't take my smallest weight. Results were basically identical regardless of the cures/exposures used.

For £55/kg, I expect a hell of a lot better.

I asked for help to see if there was any tips Photocentric could provide, but unfortunately as they had no technical data for my printer their recommendation was just to give me what was already in the TDS. Understandable, but still disappointing.

I think Photocentric should mimic what other suppliers are doing and have the option to purchase printed samples. At least in that scenario, I can test a product beforehand, or if issues arise I am able to see if it's the product's fault or my own. However in this instance I feel it is a problem with the product - I've since seen reviews of this resin on other sites, and the conclusion seems to be that it's just rubbish.
