A few weeks ago, I found that every print I attempted would fail at a certain point, and cured resin would build up on my PDMS. I clean the build platform and rake the resin tray after every build. I noticed no potential issues except for possible clouding on the PDMS. I ordered 2 new trays. When I received the new trays, I opened a fresh bottle of resin and poured it into the new tray. Same problem occurred as it did with the old tray. See pics: ![](http://forum.formlabs.com/uploads/formlabs/735/b414793797c27cce.jpg) Notice the left and right failed objects. This is how they appear in preform: ![](http://forum.formlabs.com/uploads/formlabs/737/1ae0bfb1ecfa7bca.png) ![](http://forum.formlabs.com/uploads/formlabs/736/382df9baca104c3b.jpg) Notice how the taller object sort of “cut off” at the slant? This is what’s happened every time. It’s happened with every object I print, not just these. Also, i’ve successfully printed several of the now-failing objects before… so I know the .stl files are good and the orientation/support is good. Lower objects seem to come out ok. I attribute this more to time than to height…ie - the slow buildup of hardened resin on the PDMS. Also, notice the “skin-like” buildup? That’s new to me with the Formlabs white resin, and with the new build tray. I saw on a previous thread that someone thought maybe the new firmware had a laser power issue causing this? I can’t print without a failure, or without buildup on my PDMS - please help. Any ideas? ---

Hi, I realise this is a very old post but I want to see if you got the problem fixed @Thomas_Henderson ?? I am having the same issue, after about 60mm of printing all prints seem to fail. Thanks! Ian ---
