Why FLX-300 is Your Best Choice for Your Next Project
Flexible, Resilient, and Long-Lasting. Premium Elastomer Resin for Soft-Touch Parts That Stay Flexible Over Time.
Long-Term Flexibility
Unlike typical flexible resins that gradually harden, FLX-300 maintains consistent softness and elasticity long after curing. Your parts behave reliably for extended use, not just the first few weeks.
True Silicone-Like Feel
FLX-300's silicone-like flexibility at 44A Shore hardness creates parts that compress, stretch, and spring back naturally. Ideal for grips, seals, dampers, and soft-touch components.
Excellent Shape Recovery
FLX-300's low compression set means your gaskets and flexible joints bounce back to their original shape after repeated compression. Parts maintain their form and function through many cycles.
Replacement Gaskets Without the Wait
FLX-300 lets maintenance teams print custom gaskets and seals on demand instead of ordering from suppliers. Its low compression set means printed seals maintain contact pressure over time, perfect for equipment repairs where downtime costs more than the part.
Soft Grippers That Actually Grip
Print robot grippers that handle delicate objects without crushing them. FLX-300's 44A Shore hardness and high elongation create compliant fingers that conform to irregular shapes, ideal for research labs and automation projects where you need gentle, adaptive handling.
Custom Dampers for Any Mount
Design vibration isolators with the exact geometry your equipment needs. FLX-300's elastomer properties absorb shock and reduce unwanted movement in camera rigs, drone mounts, and precision instruments where off-the-shelf dampers don't fit your setup.
Frequently asked questions
Does FLX-300 work with my 3D printer?
Yes, FLX-300 works with LCD and DLP printers using 365-420nm light. Important: never use PDMS vats – FLX-300 will damage the silicone. Warm resin to 25°C before printing. Settings: ameralabs.com/3d-printing-settings
How soft is FLX-300?
44 Shore A, which is silicone-like softness. Much softer than TPU filaments (typically 85-95A). True rubber feel after curing.
Will FLX-300 tear during use?
No, FLX-300 has high tear resistance (6.4 kN/m) for gaskets, seals, dampers, and functional prototypes.
Does FLX-300 spring back after compression?
Yes, compression set is only 1.7% at 25°C. Parts reliably return to shape after repeated squeezing.
Does FLX-300 feel sticky after curing?
No, smooth silky surface after proper post-curing. Stays that way over time, unlike generic flexible resins.
Does FLX-300 stay flexible over time?
Yes, internal testing showed no degradation in flexibility or hardness after 3 months.
Can I wash FLX-300 prints with water?
No, use IPA only. Maximum 30 minutes to prevent material degradation. Handle gently, dry completely before post-curing.
