PEBA is a polyether block amide, a thermoplastic elastomer. Makers sell it for protective gear, phone cases, shoe outsoles and sports equipment, and a maker cites its high energy return. Printed flat it reaches a tensile strength of 30 MPa and breaks at 1,050 % elongation. On the H2C it prints without chamber heat, and makers advise drying it, a maker thoroughly before every print.
Partly documented Tensile modulus (XY), tensile strength (Z) and price rest on 1 product each and notched Charpy impact is not published. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar. Products with an added filler or additive are shown but kept out of the medians.

Among the materials
Against TPU 95A class, PEBA's tensile strength (XY) is about the same: 30 MPa against 29 MPa. Against TPU 85A class and softer, PEBA is 36 % stronger flat. Among the materials, PEBA has a high elongation at break (XY) and a low tensile modulus (XY), tensile strength (XY), tensile strength (Z) and density: each is in the top or bottom quarter of the materials that publish it. Its price sits in the middle half.
Against its alternatives, PEBA has the highest price and the lowest tensile strength (Z)
How does it compare with what an engineer would buy instead?
- PEBA: its products' median and middle half
- an alternative
- lowest to highest
- each material's median (top row)
- beyond the scale
Each row is a material, each column a property: the bar is the middle half of a material's products, the tick their median, the hairline their lowest to highest; the ticks above the rows are every material's median.

Mechanical properties
Printed flat (XY), PEBA typically reaches a tensile strength of 30 MPa at a modulus of 90 MPa, and breaks at 1,050 % elongation.
PEBA's products spread most in tensile strength: the middle half runs 19.7–30 MPa
How strong, stiff and tough are its products, and which stand out?
- a product
- set apart: test bar not described as printed, or no stated load
- added filler or additive, kept out of the median
- middle half and median
- beyond the scale
One mark per product on each property's scale (zoomed where its products sit close together, as its label says); the band is the middle half of the products the median counts, and the line the median.

One temperature axis for the settings a print needs and the temperatures a part meets. A setting's shade is how many of the products whose sheets give a window accept each degree; the H2C's limit closes its row.

What makers say about printing it
Moisture sensitivity
Dry the filament thoroughly before every print, even if the spool is new.
Siraya Tech Rebound PEBA 95A, data sheet, p. 1
Printing advice
Print the first layer slower (e.g., 15-20mm/s) and slightly hotter (e.g., +5°C on nozzle) for best adhesion.
Siraya Tech Rebound PEBA 95A, data sheet, p. 1
More from makers: nozzle wear, warping and shrinkage, adhesion between layers and supports and removal
Nozzle wear
Ruby or hardened nozzle recommended: No

Warping and shrinkage

Siraya Tech Rebound PEBA 95A, data sheet, p. 1
Adhesion between layers
Excellent interlayer adhesion

Supports and removal
Supports printed in PEBA can be challenging due to strong layer bonding.

What makers warn about
Active foaming materials naturally expand in the hotend, causing oozing during travel moves.

Finish and accuracy
Briefly applying heat (e.g., heat gun on low setting, very quick pass with a torch flame) can sometimes smooth surfaces or reduce fuzziness, but exercise extreme caution to avoid melting or burning the part.
Siraya Tech Rebound PEBA 95A, data sheet, p. 1The material has great optical properties, gloss, and transparency.
