Toray unveils Toraypearl PA12 powder claiming 2.5x smoother, 2x tougher PBF parts

Toray Industries has developed Toraypearl PA12, a “truly spherical” polyamide 12 powder that the company says produces roughly 2.5× smoother surfaces (Ra ≈ 7 μm) and more than 2× the Charpy impact strength (50 kJ/m²) of conventional PA12 powders, and Toray reports sample evaluations with selected customers have been underway since January 2026. Toray positions PA12 as the dominant polymer in powder bed fusion, noting conventional PA12 powders account for approximately 70% of feedstock in the polymer PBF market because of good processability at relatively low temperatures.

Toray attributes the performance jump to its proprietary particle engineering, describing Toraypearl as “a truly spherical PA12 powder widely compatible with powder bed fusion (PBF)-type 3D printers.” The company says spherical morphology enables denser, more homogeneous powder packing that improves powder coating quality, reduces micropore formation, and therefore lowers surface roughness while increasing part density and impact resistance.

The headline numbers are specific: Toray cites surface roughness of Ra ≈ 7 μm and Charpy impact strength of 50 kJ/m², presented as roughly 2.5× and more than 2× improvements respectively over unspecified conventional PA12 powders. The announcement and subsequent coverage do not include independent third-party test reports, baseline absolute values for the benchmark PA12, or the exact test standards and specimen orientations used to measure Ra and Charpy strength, so those comparative multipliers remain company claims pending external validation.

Toray and coverage materials emphasize broad printer compatibility, describing Toraypearl PA12 as “widely compatible with powder bed fusion (PBF)-type 3D printers,” and the company expects the material to expand PA12 use from prototyping toward functional parts where durability, airtightness, and mechanical reliability matter. “The added durability, airtightness and mechanical reliability, should thereby expand its potential use in both prototypes and functional parts, explains a Toray spokesperson,” a spokesperson line reproduced in coverage states.

Toraypearl PA12 fits into Toray’s existing additive materials roadmap that includes Toraymill PPS launched in 2017 and Toraypearl PA6 introduced in 2022; prior Toraypearl PA6 deployments were noted for automotive components, office chairs, and power tools. Toray’s sampling program beginning January 2026 suggests the company is moving from lab development toward customer trials, but public data on production method, particle size distribution, recommended PBF process windows, recyclability, pricing, or commercial availability remains undisclosed.

Manufacturers and system integrators eyeing tighter surface tolerances and higher toughness in PA12 parts will watch for Toray to publish technical data sheets, safety data sheets, full test methods, and independent validation reports. Until Toray releases those details and benchmark data for conventional PA12 powders, the Ra ≈ 7 μm and 50 kJ/m² claims stand as Toray’s performance targets for Toraypearl PA12.
