Review on 2000G Black SUNLU 3D Printer Resin - Fast Curing, Low Shrinkage & High Precision For LCD DLP SLA Printers by Jeff Wyble

I started using Sunlu resin when it was relatively new on the market and I was impressed with the quality and the price. I've been buying the 1kg grey standard resin. At the outset, I didn't need to change any exposure settings to get crisp detail and clean prints.LATELY though, I feel like the QC of the product has gone downhill quickly. Prints have been failing left, right, and center, on files I've printed a dozen times before. Failures included failure to get good bed adhesion (yes, after leveling.), ODD failures such as the quality of the supports degrading and ripping in the middle of the supports, and peel cracks in the print where the exposed layer didn't adhere to the previously cured layers. Print detail quality is much softer when I *do* get a successful print, and it takes much longer to wash the print in IPA than it used to, even when using brand new clean IPA. And most tellingly, the IPA gets fouled a lot faster from heavy particulates. I think with some settings tweaking to increase per-layer exposure times this might be an okay resin, but when you have lots of pre-sliced models already on a drive and a cottage business to run, you don't want to waste your time going back to re-slice every single file with new settings. I just went back to my old standby resin. It's more expensive but without changing a single thing on my printer, the prints just started coming out beautifully again. I wish I could use Sunlu but until they address their quality issues (which, again, were GREAT when I started using them!) I just can't afford to waste time and money on failed prints.
