3D printing resin LumiReact FLX.

Lumireact FLX has an extremely quick rebound performance and firm compression properties allowing you to 3D print part that can be compressed.

After long studying and testing, we finally found the right Flexible resin!

It is available in a clear translucent red color in two versions for both SLA and DLP/LCD printers.

To improve interlayer adhesion and bulk mechanical properties, we recommend a slight over-cure of the resin if necessary.

Finishing Instructions

Lumireact Flex requires post processing and post curing to achieve specified properties.

  1. To clean and remove excess resin, agitate the 3D printed part in an ulkltrasonic cleaner with TEK1969 cleaning or in a simple vat with TEK1960 solvent* for 1-2 minutes until all excess resins has been removed.

  2. Never soak. Use a soft brush if necessary.

  3. Clean off any excess of cleansing liquid with a cold blowdryer or compressed air.

  4. Leave under the sun or in a UV lamp to cure.

  5. Even after full post cure some parts may still have a sticky surface. You can treat your print with Ta-Tack Away. A quick wash in this special formula will add a stick-free coating on the printed part.

Store the resin in a dry, cool, shaded place out of direct sunlight.


General suggested timing on DLP 3D printers*

 Layer Thickness             50um            100um
 Base cure time               25s                 25s
 Layer cure time                 5s                   7s

On Formlabs it is suggested to use Formlabs Clear version 2 (FLGPCL02) setting. Due to the high elongation of the product, care must be taken to ensure good re-lease from the resin tray every layer.

*We cannot test our resin on every single 3d printer model. Please use this timing as a starting point to find the correct curing time on your ow 3D printer.
