Error Cause Solution
Delamination
• Peeling or separation between
printed layers
OR
• Pieces of cured parts float in
the resin tank
• Model orientation, layout,
and/or support issues
• A print that has been paused
for a long time
• An older resin tank
• A loose build platform
• Contaminated optical
surfaces
• Check the model in PreForm
• Check for pauses in printing
• Check the resin tank for
debris or damage
• Check the cleanliness of
optical surfaces
• Check the stability of the
build platform
Non-adherence
• Prints partially attached to the
build platform
OR
• Prints completely non-existent
on the build platform
• Printing without supports
• The first layer of the part on
the build platform is too small
to withstand peel forces
• Debris/damage in resin tank
• Contaminated optical
surfaces
• Build platform height requires
adjustment
• Print with a base and
supports
• Check that the first layer’s
surface area is suciently
large
• Check the resin tank for
debris or damage
• Check the cleanliness of
optical surfaces
• Check the build platform
height
Overcompression
The base printed onto the build
platform is thinner than expected
and/or very dicult to remove.
The initial layers fail to cure
properly, due to insucient
space between the build
platform and the flexible film.
• Increase the base height in
PreForm’s advanced settings
• Check the build platform
height
Poor surface finish
• Cured or partially cured resin
forms thin, shelf-like structures
that hang horizontally from
a print
OR
• A rough, uneven, or bumpy
surface texture forms on one
or both sides of an otherwise
successful print
Diused laser light spreads
the cure area beyond the
appropriate limits for each layer
outline, due to:
• Expired resin
• Debris/damage in the resin
tank
• Contaminated optical
surfaces
• Restricted resin flow due to
improper model orientation or
overly dense supports
• Check the resin’s shelf life
• Check the resin tank for
debris or damage
• Check the cleanliness of
optical surfaces
• Check for restricted resin flow
Undeveloped feature
A void of missing material forms
within a print and widens as the
print builds away from the build
platform.
• Debris/damage in resin tank
• Model orientation, layout,
and/or support issue
• Contaminated optical
surfaces
• guideCheck the resin tank for
debris or damage
• Check the model in PreForm
• Check the cleanliness of
optical surfaces
Holes or lines
Models have linear cuts or holes.
Obstructions in the optical path
block the laser from curing resin
in a specific part of the model.
• Check the resin tank’s
underside for debris or
damage
• Check the cleanliness of
optical surfaces
