3d Printing Issue--Correct Orientation of wings?

[Citadelgrad]

Hi.  I got a big Anycubic Photon Max printer for Christmas.  I set it up and followed the instructions to the letter. 

 

I successfully printed a 1:1 Megalodon tooth, but when I went to print a Colonial Viper, I had a print fail on the wings.  I had them aligned along an edge to minimize layer lines and avoid supports, standing straight up on the bed.  One printed about 90%, then split between layers.  I can't tell exactly what happened with the other one because it's still printing, but it did not print correctly.  Other parts, including about a 13" fuselage section, appear to be printing normally.     

 

Since wings are kind of specific, I wondered if anyone has any tips on printing wings, is my orientation wrong??  That's the first on the list when I google why resin prints separate.

 

I don't think it's resin temp, it's in the mid 60s in the garage and I am using the vat heater function.  

 

Resin is Anycubic abs like 2.  Exposure is 1.8 seconds, IIRC, the factory default for this printer and resin combo.  I printed an exposure cones model and the Meg tooth successfully before this attempt.  I have another plate of parts to print that I will re print the wings on, but wanted to try to chase this down.    

 

Thanks for your thoughts.

Mid 60s still might be a little too cool for some printing, sounds like some issues that I had sevaral years ago that turned out to be low temps, I always keep temps above 70 degrees F. I use my printer inside the house, I have a dedicated model room and I use a inexpensive mylar lined vinyl printer inclosue that's vented with a small fan out a window through a cheap clothes dryer window vent. I don't turn the house heat way up to print, but I find that when the inclosure is zipped up the heat from the printer keeps the temp up quite nicely, I to run the Anycubic Photon 7 and have no heater, yours with the vat heater in an inclure would probably bring the temp up nicely. Anything bove 70  degrees F always seem to help.

Hope this helps,

Pat

Using an M7 pro, so similar to your max.  I'm definitely not the most experienced. 

 

I have not found a single angle that works in every regard for every type of part. I had a lot of issues getting an angle for some studio scale x wing wings that gave good dimensional accuracy, no issues printing, and not bad lower edge. I saw some layer peeling on the internal fuselage bulkheads that were at about a 30* angle and kind of narrow, but internally where it didn't matter.

 

As far as temp, I think you're fine. The basement bathroom I print in ranges from 60-70 degrees ambient, but the vat heater and having a lid on it means the resin and temp inside the enclosure is well above. The only time I had what I think we're temp related issues were when it got into the 50s and I was still on my last printer with no vat heater. 

 

I would try slowing down the initial lift speed a bit.  Also, play with the orientation some to avoid layers that are long and very thin... Try to make it so the layers have more surface area for adhesion. 

 

There's prob more troubleshooting you can find if you search for "3d resin printing layer adhesion issues" or similar.
