As with normal FDM 3D printing, SLA and MSLA resin printers create their prints in layers.
These layers need to bond strongly to each other for the print to have structural integrity.
Delamination looks terrible and breaks the structure of your print.
Thankfully, this issue is generally relatively simple to fix.
Troubleshooting Tips for Delaminating Resin Prints
The first thing to check for is the presence of minima.
These tend to either stay stuck to the bottom of the vat or float away.
In either case, they mess up future layers and cause a range of issues, including delamination.
The next thing to do is to check your resin.
These pieces of debris can get caught in a print or block the laser, weakening the print structure.
Use a resin comb or pour it through a filter to remove any debris.
The interfacing layer degrades with use; eventually, you will need to replace it.
Once youve done so, check the bottom of the vat if this isnt your first print.
Finally, all resin prints need to go through a post-processing procedure.
This involves cleaning off any unset resin and then curing the print.
However, this isopropyl alcohol washing process does reduce the bonding strength of the layers, potentially causing delamination.
Conclusion
These tips should help you to resolve any delamination issues youre having with your resin prints.
