If your print fails: quick diagnosis for 3Dresyns® resins
This page helps users identify the most common early print failures and decide which variable should be checked first.
Purpose: provide a short and practical diagnostic route before moving to deeper troubleshooting.
1) Quick diagnosis route
Start with the most common failure mode
Use the first symptom that best matches your failed print. In early-stage troubleshooting, the simplest diagnosis is usually the most useful one.
The print detached from the build platform
This usually indicates that the initial adhesion stage is not strong enough.
- Review bottom exposure time.
- Review number of bottom layers.
- Review basic platform preparation and workflow consistency.
The printed part is too soft or too weak
If the printed geometry is too soft, weak or tender, the standard-layer exposure may be too low for the real printer conditions.
- Review normal exposure time.
- Review whether the selected layer height matches the exposure logic.
- Review whether the resin and printer conditions are stable.
The part is too brittle or sticks too strongly to the release film
If the part becomes excessively brittle, loses detail or adheres too strongly during separation, the exposure may be too high.
- Review normal exposure time.
- Review whether over-curing is reducing detail.
- Review whether the selected geometry is too demanding for the current settings.
Printability is acceptable but fine detail is poor
If the print completes but detail is poor, the workflow may be too heavily biased towards excess cure.
- Review normal exposure.
- Review whether the first print is already beyond the practical working window.
- Re-check detail using 3Dtest1.
The printer worked before, but now the result is unstable
If the same workflow no longer behaves as expected, the cause may not be the original settings themselves.
- Review real UV power and possible optical drift.
- Review temperature and resin condition.
- Review whether a printer component, layer height or workflow condition changed.
- Review whether revalidation is required.
If an important variable changed, do not assume the old process window is still valid.
2) When quick diagnosis is not enough
Move to deeper troubleshooting when needed
If the failure is repeated, unclear or linked to multiple variables, move to the more complete support route.
- Use the Photopolymer Printing Failure Atlas.
- Review the IFU and Fast IFU.
- Re-check the software parameter guide.
- Use CRT and structured calibration where required.
