Flexible filament from Siraya is made for prints that bend, stretch, and rebound without breaking.
With options ranging from soft TPU to elastic PEBA blends, these materials give you freedom to create parts that are lightweight, durable, and impact-resistant.
At Siraya, we design flexible filaments that are easy to print and ready for real-world use.
Create Parts That Bend Without Breaking
Flexible filament is perfect for prints that need to flex, compress, or absorb shock. It’s strong enough to handle stress while staying elastic.
Elasticity That Feels Natural
These filaments rebound quickly and keep their shape after repeated use. They’re great for wearables, grips, and protective parts.
Stretches without tearing
Rebounds to original form
Soft, rubber-like feel
Get Strength and Softness in One Material
Siraya flexible filaments balance toughness with comfort. You can print parts that are both durable and pleasant to handle.
Tough Yet Comfortable Performance
From TPU to PEBA, each blend offers different levels of softness and strength, so you can choose the right feel for your project.
High impact resistance
Smooth or grained surface options
Soft textures for ergonomic designs
Print Lightweight Parts With Foaming Technology
Some flexible filaments are engineered with active foaming. This makes prints lighter without losing strength.
Lighter Weight With the Same Durability
Foamed flexible filament cuts part weight by up to 50%. It’s ideal for projects where softness and low weight matter.
Reduces print density
Adds fabric-like textures
Keeps elasticity and durability
Enjoy Stable Printing for Flexible Materials
Siraya flexible filaments are optimized for smooth extrusion. They’re designed to work well on direct drive printers and advanced setups.
Reliable Printing Without the Jams
With the right settings, you can print flexible filament consistently. They’re tuned for better flow and fewer clogs.
Flexible filaments include TPU, TPE, and PEBA. These materials are designed to stretch and bend without breaking, making them useful for wearables, seals, and shock-absorbing parts. Their elasticity depends on hardness levels, usually measured in Shore A or D.
Is PLA or PETG flexible?
PLA and PETG are not considered flexible filaments. PLA is rigid and brittle, while PETG is tougher and slightly more impact-resistant but still not truly flexible. Neither can match the stretch and rebound of TPU or PEBA.
Can flexible filament be used on any printer?
Not all printers can handle flexible filament. Direct drive extruders are best because they shorten the path between the gears and nozzle, reducing jams. Bowden setups can work with tuning, but they often struggle with very soft materials.
Is PETG more flexible than TPU?
No, PETG is not more flexible than TPU. PETG is semi-rigid and can bend slightly without breaking, but TPU is designed to stretch and rebound. TPU filaments are much softer and elastic compared to PETG.
