Elastic 50A V1 Resin


Embrace the flexibility of Elastic 50A Resin V1, perfect for creating soft, flexible prototypes akin to silicone. Ideal for wearables, compressible buttons, stretchable enclosures, robotics, medical models, and special effects, it offers versatility in design.

Key Features of the Formlabs Elastic 50A V1 Resin:

  • Enables prototyping of soft, flexible parts
  • Mimics silicone for realistic feel
  • Withstands repeated bending and stretching w/o tearing
  • Bendable parts spring back quickly
  • Ideal for straps, compressible buttons, casings, medical models, and more
  • Legacy formulation of Elastic 50A Resin

Note: Elastic 50A Resin V1 will be discontinued, making way for V2 with enhanced features like easier support removal, faster printing, and improved transparency.

Notes Notes
Wash Elastic 50A Resin for 10 minutes on
the build platform. Remove parts from the
build platform, then wash for 10 more
minutes using fresh solvent. Avoid washing
Elastic 50A Resin for longer than 20 minutes,
as this may degrade parts.
For parts printed in an engineering-focused
resin (such as those in the Rigid, Tough &
Durable, and Flexible & Elastic families),
post-curing ensures that the parts reach
their optimal mechanical properties and
can function as designed. There is only one
recommended post-curing time for Elastic
50A Resin.
