Failed prints - My top 5 fails

by Antharon

After 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.

AnyCubic Photon: Prints Fail Halfway

by Fallout78N

I bought, what in hindsight is looking more and more to be a mistake, an AnyCubic Photon. For two weeks I have struggled to get it to print correctly, but my prints either stick to the bottom of the tank, or, more frustratingly, just stop printing halfway. I've leveled the build plate more times than I can count, completely wasted a bottle of resin, and have probably done irreparable damage to my sanity. The only two conclusions I can come to are either FEP film is the single most adhesive substance ever created, or the AnyCubic photon is a piece of trash that would be better off chucked out a second story window into the driveway. I've watched every video I can find, followed all the advise, and am no closer to success than I was two weeks ago. I'm out of ideas, out of patience, and almost out of resin, so any suggestions are welcome. I'll include a picture of what I'm trying to print, and a picture of the spot in the program it keeps failing.

Anycubic Wash & Cure Machine

by Wolf_Assassin

Im considering buying the Anycubic Wash & Cure machine and the question is if it is worth the money?

My home made uv box is crap and dont cure anything, dont thing the UV led strip is on the right wave lenght even though they should be according to the specification. I can have the print in the UV box for hours and it remains sticky. So im looking at the Anycubic Wash & Cure machine.

Im wondering how the bucket for the ipa survives all the resin that is washed from the printed parts? Today i have a glass jar that i whased the parts in manualy and it has a thick layer in the bottom. The same thing should hapen to the bucket so the question is how long it will take before you have to replace it?

Hi, my three last prints have came out damaged in this strange way. What might be the cause? Supports, stabilisation or something else? And how to solve this issue?

Prints not sticking - what else can I do?

by Gooru

I know this is a basic problem but I tried everything t know to solve it.
My prints don´t stick to the printbed 80% off the time.

I clean the printbed bevor start.
I level the prindbed every time I start a print.
I clean the VAT frim top and bottom.
I clean the display befor inserting the VAT.

But no matter what I do - my prints stick to the VAT and not to the printbed.
Sometimes I manage to get some supportstructures printed, but when the "real part" starts, it gets ripped of the supports at some time.
So my conclusion is, my VAT is too sticky but i don´t know what to do to change this behavior.
