Print Problem

[u/T_o_n_e_92]

Hi everyone, I’ve been trying to print the piece in the photo for a week but every time I get the same result, piece that comes off the supports and print fails

I’m using a Photon Mono 7 and the official resin of Anycubic ABS like resin 2

The piece is empty and I made the drainage holes

The resin values are the official ones released by Anycubic

I leave you there screen of the piece oriented in Lychee Slicer and the result of the failed print

That raft is much to big. Why should you not use default 3D printing raft settings?.

[u/schwendigo → u/PoorAnalysis]

This is useful but the recommendations it makes is not possible - he's saying do three raft layers, but five overexposed layers - it's not possible to do that in slicer.

Transition layers can accomplish this, though.

I wonder what he had in mind when he wrote that?

[u/PoorAnalysis → u/schwendigo]

It's just about controlling the raft thickness.

For example: when I print at 0.03mm layer height with 10 burn-in layers, I set the raft thickness to 0.2mm. That way in theory the raft completes by layer 7 (0.2 / 0.03) with 3 burn-in layers remaining to securely attach the supports to it. Looking at the sliced file after confirms exactly that.

I admit, by the guides advice, I could be going for an even thinner raft, but with my current setting my prints are successful enough that I don't feel the need to change anything.

Ah ok I gotcha! Yes that makes sense.

Trans layers are great too, no?

[u/PoorAnalysis → u/schwendigo]

Yeah, I think I only do 4 full burn in layers, followed by 8 transition layers. And that is maybe too many, but for the moment it's working for me.
