When a resin print releases from the plate, separate setup, resin profile, and geometry in the diagnosis. Check those in turn so increasing exposure does not become the automatic response to every failure.
Make the failed print safe to inspect
Follow the resin safety data sheet and printer instructions for gloves, eye protection, ventilation and cleanup. Treat uncured resin and contaminated wash liquid according to those instructions; do not handle the failed raft with bare fingers to test adhesion.
Remove failed material using the manufacturer’s vat-cleaning method before starting another print. Formlabs’ resin-filtration guidance[1] calls for checking resin after a complete or partial failure and warns that tools can scratch, puncture or deform tank film. Use the method for your tank rather than transferring a scraper routine from another model. Check the film and plate for damage and loose material while the failed print is out; another exposure test should not begin over debris left by the last one.
Use the exact leveling procedure
Find the procedure for your model and build-plate system. Do not substitute a universal sheet thickness, press one corner of the plate or override an automatic system with an unrelated manual routine.
ELEGOO’s build-platform troubleshooting guide[2] identifies leveling, resin settings and temperature among the checks. Its leveling video demonstrates a Mars Pro, and part of its exposure discussion is explicitly limited to the original Mars. That makes it a useful diagnostic lead, rather than permission to copy the routine or exposure seconds into a different printer. Use the instructions for the build-plate system actually fitted, especially if the machine levels automatically or an accessory has changed it.
Verify the resin profile
Match the resin product and printer to the manufacturer's supported settings. Check layer height, bottom layers, exposure, transition and motion settings as a complete profile. A generic grey-resin table cannot establish the correct exposure for a different machine or resin.
Record the resin temperature and check it against the product’s specified range, then prepare or mix the resin as directed. Before adjusting exposure, write down what remained attached and what separated: an entire base released from the plate is a different observation from a base still attached with the model missing above its supports. Keep that distinction in the next test. It does not establish the cause by itself, but it stops a later support or model failure being counted as proof that the base never adhered.
Clean before modifying the surface
Use the approved cleaning method for the plate. Do not sand, add an unapproved degreaser or scrape a coated surface with a razor as a generic next step. Those changes need explicit support from the plate manufacturer.
If a flexible plate was added, verify the accessory's approved installation and required setup changes before continuing.
Test one change
Use a small manufacturer-supported validation model or a representative part. Keep the unchanged settings beside the one adjustment and record the result, including what happened to the base, supports and model. Changing leveling, exposure and motion together may produce a success, but it leaves you unable to say which change corrected the problem. A base staying attached answers only the adhesion question; inspect the rest of the part before saving the profile.
Once the test repeats successfully, save the resin, machine, geometry and settings together. You can return to that combination after a later failure and see what changed before adjusting exposure again.
