Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
Which printers is xFLEX402-Black compatible with?
xFLEX402-Black is formulated for Nexa3D NXE-series photoplastic printers running the NexaX workflow, and is a genuine Nexa3D resin validated for those systems. If you run the XiP desktop printer, order the 1 kg XiP cartridge version of xFLEX402-Black instead.
Does xFLEX402-Black need thermal post-curing?
No. xFLEX402-Black is a single-component elastomer that does not require thermal post-processing — you wash and UV-cure the part in the standard workflow and it is ready to use. That removes an oven step and shortens the time to a finished elastomeric part.
What is xFLEX402-Black used for?
xFLEX402-Black suits parts that need springiness and rebound with good elongation and durability — living hinges, bumpers, grips, seals, and functional elastomeric prototypes. Its semi-firm durometer gives resilience without going fully soft.
