Know what to do now—and what comes next

Follow one controlled path. Do not stack unrelated changes before the proof test.

Typical first pass 15–35 min

1
Confirm the visual clue
Compare the failed area with the problem and target visuals.
2
Run the safest first checks
Confirm plate leveling, resin temperature and release conditions first.
3
Print the proof test
A small validation print remains attached and completes cleanly.

Escalate only if needed
Use the next-route guides only when the original symptom remains.

Before you change settings

Confirm the exact printer, material, nozzle or resin, slicer, and recent hardware changes.
Photograph the failure before removing the print so the evidence is not lost.
Return extreme overrides to a known profile and change one variable at a time.
Use a small calibration object or representative section before repeating a long print.

What it looks like

The raft remains in the vat or only part of the model attaches to the plate.
The problem may become more obvious after speed, temperature, geometry, or print height changes.
The failure can repeat in the same region or appear only under higher load.
A correct result should match this target: The raft bonds evenly and supports the model through the full print.

Most likely causes

Build plate not leveledThe initial gap differs across the plate.
Bottom exposure too lowThe first layers do not cure strongly enough.
Plate contaminationResidue prevents bonding.
Lift force too highSuction peels the raft away.

Action plan

Repair sequence

Work from top to bottom. Stop when the failure is resolved, verify it with a small test and record the successful setup.

Step 1
Document the failure and confirm that it matches this guide: The raft remains in the vat or only part of the model attaches to the plate.
Step 2
Return extreme overrides to a known printer, nozzle, material, and slicer profile so the diagnosis starts from a stable baseline.
Step 3
Check build plate not leveled. Re-level the plate.
Step 4
Check bottom exposure too low. Clean it as specified.
Step 5
Inspect plate contamination. Use resin-tested bottom exposure.
Step 6
Rule out lift force too high. Reduce lift stress.
Step 7
Change only the single setting or hardware condition supported by the evidence, then run a small test that reproduces the original failure.
Step 8
Compare the test against the target condition, record the successful value, and save it in a printer/material profile before repeating the full print.

Safety and accuracyStay within the printer, material, resin, hotend, build-surface, electrical, ventilation, and personal-protection limits published by the manufacturers. Stop immediately for heater errors, smoke, electrical damage, severe binding, or resin exposure.

Tune carefully

Settings to review

Setting	How to use it
Normal exposure	Tune for detail and layer strength at the actual resin temperature.
Bottom exposure	Use enough for adhesion without excessive base growth.
Lift speed/distance	Control peel force and allow complete release.
Support/contact size	Match the cross-section and suction forces of the part.

Material notes

Standard resin

Use the printer/resin maker profile as the starting point.

Tough/flexible resin

Often needs different support and cure handling.

Water-washable resin

Still requires PPE and resin-specific wash/disposal guidance.

Filled/specialty resin

Mix as directed and account for settling and exposure changes.

Printer context

Bedslinger

Check bed seating, gantry alignment, belts, wheels and first-layer consistency across the plate.

CoreXY

Start with the official profile; inspect belt balance, input shaping, flow, pressure advance and chamber conditions.

Delta

Confirm delta calibration, tower movement, belt tension, effector stability and full-bed mapping.

Resin / SLA

Use resin-specific exposure, lift, support, temperature, wash, cure and protective procedures.

Where to look in the slicer

OrcaSlicer / Bambu Studio

Quality, Strength, Speed, Support and Filament; use built-in calibration for temperature, flow and pressure advance.

PrusaSlicer

Print, Filament and Printer Settings; inspect the layer preview before export.

Cura / Creality Print

Quality, Walls, Top/Bottom, Material, Speed, Travel, Cooling, Support and Adhesion.

Resin slicers

Printer/resin profile, exposure, lift/retract, support contact, raft, hollowing and drain settings.

Controlled test method

Do not repeat the full print while guessing. Use a small test that reproduces the same feature and record the result.

Save the current profile or photograph every relevant setting.
Choose one suspected cause from the ranked list and change only the matching variable.
Print the smallest useful test with the same material, nozzle, plate, and environment.
Compare the result with the target visual, keep the winning change, and then test the real model.

Standardized proof test

Test modelSmall resin validation print

Setup

Use the final resin, temperature, exposure, lift and support profile.

Pass condition

The part completes with clean details, attached supports and no layer split.

If it still fails

The part detaches, splits, warps or loses detail.

Next controlled action

Inspect leveling, release film, exposure, supports, suction and temperature.

Proof before you move on

How to verify the fix

The raft bonds evenly and supports the model through the full print.
The same test succeeds at least twice without a new artifact appearing.
No safety warning, unusual noise, heater error, binding, or material damage is introduced by the change.
The successful values are recorded with printer, nozzle, material, slicer, and date.

Run the smallest useful test first.

Choose a result after the print so the guide can point you to the correct next action.

Keep the winning setup

Prevent it next time

Keep a known-good baseline profile and duplicate it before experimenting.
Inspect the relevant mechanical or material condition during routine maintenance instead of waiting for a failed print.
Change one variable at a time and use short calibration objects to avoid wasting long prints.
Re-check the result after nozzle, build plate, hotend, firmware, slicer, or material changes.

Frequently asked questions

What should I check first for resin print not sticking to the build plate?

Re-level the plate. It is the fastest low-risk check and often separates a profile issue from a hardware or material issue.

Can build plate not leveled cause this problem?

The initial gap differs across the plate. Confirm it with the smallest safe test before changing unrelated settings.

Should I change several settings at once?

No. Multiple simultaneous changes hide the real cause and make the successful setup difficult to reproduce.

When should I stop troubleshooting and inspect hardware?

Stop if you see heater errors, electrical damage, binding, smoke, unusual heat, severe collisions, leaking resin, or any condition outside the manufacturer safety guidance.
