The very first thing you need to do is open a customer support ticket, if you haven’t already done that - they really helped me. Apart from that, I can add my personal opinion, however I have only had a little over 2.5 months experience with the Form1+ and this is the first 3D printer I have used: 1. The initial prints look good from the quality - the upper surfaces without supports look really nice and smooth, as they should… but they failed. I think this will be for one (or more) of several reasons, such as a) resin starvation, b) insufficient supports, c) adhesion to the resin tank, d) … 2. After a failed print, you need to really carefully make sure there is nothing still stuck to the tank bottom or floating around in the tank - the support pages on the [formlabs.com](http://formlabs.com) really have the information you need to initially follow. 3. The models you are trying to print are quite demanding, and I believe they would usually be broken into multiple pieces to increase the quality of the finished item - e.g. see [this guy’s really amazing efforts](http://forum.formlabs.com/t/3d-print-of-joe-grundfasts-war-machine/4732) 4. After showing a dirty 4th mirror (the last in the laser path), you show a model of a skull where there is obviously a ‘new’ problem (not apparent in the other model photos at least) of dirt or other problems on the optics - look at the supports of your model and this one I printed while I was having similar problems: ![](https://us1.discourse-cdn.com/flex025/uploads/formlabs/original/2X/0/06275e6307d594c8682782efb35800479ab4e1b3.JPG) I was close to despairing, but support really helped guide me through it… you MUST open a customer support ticket before opening your machine and trying to clean anything or you will void your warrenty; support will guide you on what to clean, when to clean it, and most importantly how to (and how not to) clean it - I wrote a longer post on my experiences [here](http://forum.formlabs.com/t/great-support-mirror-cleaning-faith-restored-death-to-the-giant-flake-s/4873). In the mean time I am printing successfully, everything is going well… so don’t give up, go open a ticket [from this page](http://formlabs.com/support/troubleshooting/). --- _[View the full topic](https://forum.formlabs.com/t/i-tested-10-times-all-fail-help/5996)._
