Add Some Flex

To make standard resins less brittle, flex can be mixed to produce varying degrees of flexibility to firmness. By adding a small amount of flex creates a less brittle and more durable part. By adding larger amounts, the more flexible it will become.

Or print 100% with flex to get a TPU like product.

  • Fast printing, less deformation, high precision with smooth surface.
  • Impact resistance, anti- folding
  • flexible with little elastic property.
  • Elongation at break: 130%


Extend the exposure time beyond recommendations.

When mixing Flex with our other resin systems, please ensure that you cure for a long enough time to fully cure the flexible resin. This is a slower curing resin and takes more UV exposure to fully cure. Although the part might look perfectly formed, if it hasn’t been cured for long enough, cracks may appear due to the resin being under cured.

Prints on most brand LCD printer, and fast printing on DLPs.

For LCD printer with colorful panel, bottom layer 30-70s and each layer exposure time 4-16s, for example, layer thickness 50 micron on Anycubic printer, base 50s while each layer 8s.

For LCD printer with monochrome panel, bottom layer 30-70s and each layer exposure time 4-8s.

For DLP printer, bottom 10-30s and each layer 1-6s.

The exposure time should be adjusted according to printer light energy, layer thickness and model structure.
