One common challenge in 3D printing is achieving strong layer adhesion, especially when printing with materials like PLA or PETG. Poor adhesion between layers can lead to weak prints, which may break or delaminate under stress. Many people have tried increasing print temperatures, adjusting print speeds, or experimenting with cooling fan settings to improve layer bonding, but results can vary.
What are some effective techniques you’ve found for improving layer adhesion? Whether it’s optimizing printer settings, using specific brands of filament, or post-processing techniques, any insights are welcome!
Let’s kick off a conversation to share ideas and strategies for creating more durable, high-quality prints with strong layer bonding!
Clean bed. I use alcohol 99% IPA if I see finger prints, and every now and again I wash the removable surface in detergent (not soap) this removes and gunk and residue.
Remember to check the material you are using with the surface you have. Dsome materials bond too well and you need glue stick to aid in the release.
Glass and glue works very well and stops curling on the corners. Use a brim too.
You can bake PLA prints to crystalize the plastic and that makes PLA extremely strong. If you watch CNC kitchen, he has got a really good video on it. Although parts shrink a lot.
I found giving PLA or PETG parts if dimensions are not too important a few coats of clear and it fills in the layers and gives some strength as well as some UV protection.
