Failed prints - My top 5 fails
by AntharonAfter first bottle of resin I have some points about failed prints for you. So how can your print fail and how to solve the problem.
1, I have found first couple layers stuck on the bottom of a vat - this is the most often problem that happened to me. It appears usually after failed print. Your calibration is off a bit and your first layer is not aligned correctly and it peels off. Your calibration can become disaligned usually then buildplate is not thightened enough and you are removing item from it, or maybe there is a piece of cured resin on the bottom of your vat from previous fail, that you did not scoop out. Recalibrate and try again. Also clean your vat and recalibrate after each failed print.
2, unfinished part of print is stuck on the bottom of vat - this is pretty similar to first case, but cause is completly different. In DLP printing your print is holding on the top of buildplate by suction force. This force is usually enough to hold your print up. But if total area of layer printed is bigger than area of first layer, it can happen, that this suction on the bottom vat is stronger and your print will get torn off. From now last layer wil be cured again an again. best method to fix this problem is rotate your print and print in angle. If you have long straight smooth surfaces and you do not want lines on them, print them perpendicular to buildplate. use supports and raft, that is bigger than your model if necessary. In this case supports should be sturdy enough to hold your print.
3, raft is stuck on buildplate, part of model is stuck on vat - this happens when your upport are not strong enough to overcome suction force from previous example. Add more suppports, use some heavy supports if there is space where they can be easily removed.
4, model is warped and shifted - your buildplate is not thightened enough and if got moved while printing. recalibrate and thighten it thoroughy
5, part of model is squashed and flat or missing - you have unsuported overhang. This should result in part being not printed at all and its projection stuck on bottom of vat, but sometimes printer manage to glue part back to model and separate it. Always support overhangs, especially "islands"
This is it, 5 mos usual non-technical printing fails with enycubic photon.
