3D Printing Dilemma: Fixing vs. Replacing Scratched Resin Plates!

Hey, tech enthusiasts! It’s Carolina, your go-to gal for all things tech-related! Ever noticed those minor blemishes on your resin plate? Been down the rabbit hole trying to understand if these are game-changers for your 3D printing endeavors? Buckle up! I’m diving deep into the nitty-gritty to help you sail through these minor hiccups with confidence.


Impacts of Scratches on Your Resin Build Plate
Believe it or not, those tiny scratches on your build plate might not be the enemy. In many cases, they can even enhance build plate adherence. But before you go on a scratching spree, it’s crucial to know that excessively deep scratches can compromise your plate, urging a fix or replacement.

You’re likely wondering how these scratches even get there. I’ve been there too! For most resin printer enthusiasts, including yours truly, that pesky metal scraper is usually the culprit. Fret not, though! Unless your scratch resembles the Grand Canyon, it’s unlikely to mess up your print quality.

The science behind this is intriguing! The resin printer efficiently fills those scratches during the first layer, improving the model’s grip on the build plate. Subsequent layers then find a leveled and smooth surface to build upon. The only trade-off? A slightly different finish at the bottom. But hey, nothing a nifty raft can’t fix, right?

Guidelines to Protect Your Build Plate
To avoid any potential damage to your FEP sheet due to raised edges from scratches:

– Always approach the build plate with the print removal scraper at a flat angle.
– For a cooler approach (pun intended!), pop the build plate in the freezer. It eases model removal post-printing.
– Swap out your metal scraper for a plastic one. Personal favorite? The Bates Plastic Putty Knife Set available on Amazon!

DIY Fixes for a Scratched Build Plate
Got a slightly wounded build plate? Here are some DIY fixes:

1. Use a Raft: This gem shields your model from any damage originating from the plate scratches. Plus, it boosts the adhesion between your model and the plate.
2. Burr Removal: Burrs can be the bane of a smooth printing experience. Slide on some gloves, identify those burr hotspots, and gently sand them down with 120-grit sandpaper. Finish with a Scotch Brite Pad for that smooth touch.
3. Full Plate Sanding: For those ‘beyond repair’ moments, you might need to sand the entire plate. Use a super flat surface (glass plates are a dream), 80 & 120-grit sandpaper, isopropyl alcohol, and a lint-free cloth. Keep sanding uniform and end with a thorough clean.

Top Resin Build Plate Replacements
If your build plate’s had its run, consider these top replacements:

Fulament Fula-Flex: A magnetic, flexible, and resilient plate. But, heads up! There’s a logo etched onto its surface that might imprint onto your models.
ELEGOO Mars Build Plate: A perfect fit for the ELEGOO Mars series, this plate promises stability, longevity, and a textured surface for superior adhesion.

Until next time, keep innovating, experimenting, and always remember – every glitch has a tech-savvy solution waiting to be discovered! Cheers to more 3D printing adventures!
