As some of you are aware I’ve been having print quality issues with my Form1+. I’ve posted on the @kevinHolmes thread “Form1+ laser flare issues illustrated – pic and video” – LINK some typical examples. Although there are similarities with print quality, I feel there are more factors at play them…

[image] KevinHolmes: Also - I think you are confused about layer heights - before the latest Preform update, 0.1mm was the thickest layer height - and will minimise flare issues with prints. So rather than “even at 0.1mm” you should be looking for “even at 0.05mm”, or even at “0.025mm” - and was…

@Steve_Johnstone what I meant was that you’re possibly conflating two separate issues - cold resin causing bubbling/hollows, and flare causing bad surfacing and flaking. I don’t see that you can conclude cold resin makes flare issues worse is my point. My contention is that cold resin is likely suf…

@KevinHolmes I fully understand where you are coming from, but that doesn’t explain why the major faults never once appeared on the hinge or peal sides surfaces of any print I’ve done to date. For your argument to be true I would have at some point seen bubbling / hollows throughout the prints, not…

@Steve_Johnstone but how can bubbling/hollows have a “side” or “surface”? - those parts are only 2mm thick - the bubbles must be in the middle of the part. If your point is that the bubbles appeared only in the y-axis (or x? not clear from your pics above) oriented slab-features and not the in the …

@Steve_Johnstone Can you please post pictures of those same prints after washing.

[image] KevinHolmes: @Steve_Johnstone but how can bubbling/hollows have a “side” or “surface”? - those parts are only 2mm thick - the bubbles must be in the middle of the part. The solid parts e.g. the rook have the major bubble flaws on the rear facing surface. The last print I tried before …

@Steve_Johnstone ok - that rook bubbling is interesting. So what’s the theory; that flaking on the flare side can act as traps for air bubbles? I think it’s obvious now why cold resin can cause bubbles/hollow parts - cold resin is more viscous, and once past printing the base and into printing the …

Well I couldn’t reproduce the bubbled parts problem by reducing the temp - although I did only try a couple of times. I turned off the heating left the window open over night. It was 12degC in the morning - which produced one complete failure. Then after shutting window and warming to 14deg - I mana…

@Steve_Johnstone , @KevinHolmes , Unfortunately i have encountered similar problems with my latest prints and I don’t have a solution for it either. Hopefully we’ll be able to fix this together because it’s affecting my prints in a bad way as well. Like Steve’s print. I have rough surfaces at the fr…

Trouble Shooting – Part cured resin (jello) after every print

For clarification. The prints I did of the same file on our now defunct thread were done at 20.9C. The fume hood I run the printer in and that room have good temp control because of the other stuff done in that space.
