Resin Print Perfection: 9 Fixes for Pesky Vertical Lines!

Alright, Carolina here – your go-to tech enthusiast! Let’s dive into the mesmerizing world of 3D printing and address one of the most common hiccups many enthusiasts face: those pesky vertical lines in resin prints. Let me guide you through some tried-and-true methods to tackle this challenge.


Understanding and Resolving Vertical Lines in Resin Prints

1. Gently Tilt the Model
A simple tweak like adjusting the vertical orientation of your model can often do the trick. Alias-induced vertical lines might diminish when you rotate your design just a tad.

By the way, a neat trick from an experienced user: before hitting the print command, open up those .photon files in ChiTuBox. It’ll give you a glimpse into any potential issues.

2. Experiment with Unique Angles like 31° or 47°
Shake things up a bit by rotating your model at unconventional angles. There’s chatter in the 3D printing realm about angles like 31° or 47° being game-changers for eliminating vertical lines. Worth a try, right?

3. Twiddle with Your 3D Printer’s Eccentric Nut
This might sound odd, but fine-tuning the eccentric nut can help. While it’s a solution for many, be aware that it might not be the magic bullet for everyone. If you’re new to this, there’s a handy tutorial by Anycubic on YouTube. It’s super helpful!

4. Ensure the Build Plate is Snugly Secured
A loosely attached build plate can be your worst enemy. Make sure to firmly tighten that top thumbscrew. As an upgrade, consider using longer screws that can be managed with a proper wrench. It’s a game-changer for many seasoned printers.

5. Decelerate the Lifting Speed
The culprit behind those vertical lines can sometimes be a high lifting speed, particularly if your printer is placed on a wobbly surface. Slow things down, and while it might lengthen your print time, the impeccable result will be worth the wait.

In the quest for perfection, TSMC (two-stage motion control) is making waves. This technique lets you adjust the build plate’s movement in two distinct stages. Intrigued? Dive deeper with a tutorial by 3DPrintingPro.

6. Opt for Superior STL Files or Revise the Current One
Ensure your STL files are top-notch. Remember, the intricacies of the model can directly impact the print quality. So always prioritize high-resolution files.

7. Refresh with the Latest Firmware
Outdated firmware could be secretly sabotaging your prints. Stay updated. For instance, some Elegoo Saturn users benefitted immensely from a firmware refresh. Yasmeen Yarkspiri’s video guide on firmware updates is a treasure trove of information.

8. Purge Cured Resin from FEP Film
A clean FEP film is crucial. Any cured resin remnants can throw off your prints. When cleaning, always sidestep metal scrapers. They can cause more harm than good. Submerge the film in clean IPA overnight, and voilà! The cured resin usually peels off easily in the morning. Slice Print Roleplay has a stellar tutorial on this.

9. Switch Up Your Slicing Software
Sometimes the software itself could be causing those vertical line woes. Experiment with different slicers to see if there’s an improvement. While I’m a huge fan of Lychee Slicer, the evolving features of ChiTuBox are making it quite enticing.
