Common problem

FAQ

Bottom layer not sticking, model fails to print

Check leveling; check if the build plate is pressing against the light-blocking strip; check if the build plate is warped; check slicing parameters; check exposure time; for large models, try hollowing them out.

First layer sticks, but the second layer doesn’t

Minimize the bottom layer area; avoid using sloped raft bases; avoid full-plate bottom layers; use multiple small circular bases instead, ensuring they are not connected.

Model fails to print

Check if supports are too thin; check print speed; check exposure time; check model orientation; check tightness of build plate and resin vat screws; check release film.

Partial model fails to print

One side succeeds while the other fails due to improper leveling; edges succeed but the center fails due to insufficient lift distance or excessive retract speed—adjust parameters accordingly.

Model quality issues

For designs prone to vacuum peeling, add side vents; use slicing software with precise algorithms; prefer NFEP or higher-grade release film.

Model breaks cleanly at cross-sections

Likely caused by multiple factors: design issues, motor step loss, Z-axis instability, slicing software, or temperature/humidity—try changing resin or adjusting resin formula.

Printed model cannot be assembled

Reduce light intensity and exposure time; apply tolerance compensation to the design (enlarge holes, shrink pegs); post-process by sanding.

Debris of various forms during printing

Lower light intensity—excessive light causes overexposure and debris; check if resin is exposed to sunlight (UV causes peeling); burrs or flakes indicate loose release film.

Model warping issues

Occurs during curing phase; resin is too soft; uneven or incomplete curing; improper support placement; lack of supports after hollowing or walls are too thin.

Severe pixelation on model

Tilt smooth curved surfaces at an angle to the build plate; add anti-aliasing for overly smooth models; post-process by sanding.

Resin shelf life

As long as it remains liquid, it can be used; resin left in the vat absorbs moisture, increasing print time—return to bottle if unused for long periods.

Model cracking

Caused by moisture absorption; prolonged soaking in alcohol or water; incomplete cleaning; insufficient curing; layer thickness too high (recommend 0.03mm–0.05mm).
