Axtra3D and Arkema gain UL Blue Card for N3D-FR512

Key Takeaways

• Arkema’s N3xtDimension N3D‑FR512 flame‑retardant photopolymer earned UL Blue Card certification for use on Axtra3D’s Lumia X1 high‑speed SLA printer.
• Certified test data show a tensile modulus of 5,100 MPa, tensile strength of 42 MPa, elongation at break 4.2 %, and a heat‑deflection temperature of 170 °C (0.455 MPa).
• The Lumia X1 employs Hybrid PhotoSynthesis (HPS)—a laser + DLP projector blend—that delivers fine feature resolution, superior surface finish, and up to 2× faster build rates than conventional laser‑only SLA systems.
• UL’s Blue Card is part of the Plastics for Additive Manufacturing (P‑AM) program, offering independently verified material performance data that engineering and procurement teams can cite in supplier and material selection processes.

UL Blue Card Certification for N3D‑FR512

Arkema and Axtra3D announced that the N3xtDimension N3D‑FR512 photopolymer has passed UL’s rigorous Blue Card evaluation when processed on the Axtra3D Lumia X1 SLA platform. The Blue Card provides a standardized data set—mechanical, thermal, and fire‑performance metrics—under defined printing parameters, giving buyers a documented reference point for material qualification.

What the Blue Card Covers

These figures confirm that N3D‑FR512 is suitable for rigid functional components where flame resistance and high‑temperature stability are mandatory—e.g., aerospace brackets, electrical enclosures, and automotive interior parts.

Lumia X1: Hybrid PhotoSynthesis (HPS) Technology

The Lumia X1 is built around Axtra3D’s patented Hybrid PhotoSynthesis (HPS) process, which simultaneously projects a DLP image and traces a laser line across the resin vat. This dual‑exposure approach yields several practical advantages:

The HPS architecture enables fine‑feature reproduction while maintaining high throughput, a combination that is traditionally difficult to achieve with single‑source SLA systems.

Why the Certification Matters

• Risk Mitigation – Engineers can reference the Blue Card data during design reviews, reducing the need for costly in‑house material testing.
• Supply‑Chain Transparency – Procurement teams gain a third‑party validated performance sheet, simplifying supplier audits and compliance checks.
• Regulatory Alignment – For industries bound by fire‑safety standards (e.g., UL‑94, IEC 60695), the Blue Card offers documented proof of compliance.

UL notes that while the Blue Card confirms material performance under the test conditions, final part suitability still depends on part geometry, post‑processing, and specific application requirements.

Bottom Line

Arkema’s N3D‑FR512 photopolymer, now UL‑certified for the Axtra3D Lumia X1, delivers a compelling mix of flame retardancy, high stiffness, and thermal resistance—key attributes for demanding functional parts. The Lumia X1’s Hybrid PhotoSynthesis platform adds speed and surface quality to the equation, positioning the system as a strong contender for manufacturers seeking certified, high‑performance SLA solutions. The UL Blue Card serves as a trustworthy, data‑rich reference that streamlines material selection, compliance verification, and risk management across aerospace, automotive, and electronics sectors.
