Key Takeaways
- New material: Formlabs launches Nylon 11 Pro Powder for the Fuse 1+ 30 W SLS printer.
- Future rollout: Compatibility with the Fuse X1 is slated for Q1 2027.
- Mechanical edge: ~5× higher elongation at break and ~2× greater notched Izod impact strength versus the standard Nylon 12.
- Design freedom: Retains thin walls, snap‑fits, living hinges, and fine features through blasting and tumbling.
- Target parts: Flexible prototypes, end‑use components, jigs, fixtures, orthotics, prosthetics, and wearable devices.
Introduction
Formlabs has expanded its material portfolio with Nylon 11 Pro Powder, a high‑performance polymer engineered for the Fuse 1+ 30 W selective laser sintering (SLS) printer. The company also announced that the same powder will be qualified for the Fuse X1 platform in the first quarter of 2027, giving users a longer‑term, flexible solution for functional parts.
Material Overview
What is Nylon 11 Pro?
- Polymer type: Polyamide 11 (PA‑11) powder, optimized for SLS.
- Refresh rate: 30 % (identical to Formlabs’ Nylon 12, enabling predictable material usage).
- Particle size distribution: 20–70 µm, tightly controlled for uniform layer spreading.
- Laser power requirement: 30 W (compatible with existing Fuse 1+ optics).

*Measured on ISO 527‑2 Type 1A specimens; values represent average of three builds.
Performance Highlights
Superior Ductility
Formlabs reports that Nylon 11 Pro delivers approximately five times the elongation at break of Nylon 12, allowing parts to flex repeatedly without cracking. This property is critical for living hinges, snap‑fit clips, and thin‑walled ducts.
Impact Resistance
The powder’s notched Izod impact strength is roughly double that of Nylon 12, translating to better protection against sudden loads—ideal for protective housings and wearable devices.
Isotropic Behavior
Because the polymer exhibits consistent elongation across all print orientations, designers can rely on predictable performance regardless of part layout on the build platform.
Post‑Processing Resilience
Nylon 11 Pro retains fine features (walls < 0.8 mm, hinge radii < 0.5 mm) during media blasting and tumbling, reducing the need for secondary machining or reinforcement.
Target Applications
| Application | Why Nylon 11 Pro? |
|---|---|
| Impact‑resistant prototypes | High Izod impact mitigates breakage during functional testing. |
| End‑use components | Long‑term flexibility and durability extend service life. |
| Jigs & fixtures | Elastic recovery maintains dimensional accuracy after repeated loading. |
| Snap‑fit & living hinges | Five‑fold elongation prevents hinge fatigue. |
| Orthotics & prosthetics | Biocompatible PA‑11 offers comfort and resilience. |
| Wearable devices | Lightweight (1.01 g/cm³) and flexible for ergonomic designs. |
Availability & Roadmap
- Immediate: Packaged for Fuse 1+ (30 W) shipments starting October 2026.
- Future: Validation for Fuse X1 (higher‑power 45 W system) scheduled for Q1 2027, with a projected launch in March 2027.
- Pricing: List price of $210 per kilogram, comparable to Nylon 12’s $195/kg, reflecting the added performance.
Comparison with Existing Nylon 12
Formlabs’ standard Nylon 12 remains a workhorse for rigid parts, but its limited elongation (≈30 %) can cause brittle failure in flexing features. Nylon 11 Pro’s 150 % elongation and 2× impact strength close the gap between prototype and production‑grade elastomers, while preserving the familiar 30 % refresh rate that simplifies inventory management.
Production Considerations
- Build envelope: No change; part size limited to Fuse 1+’s 165 × 165 × 200 mm volume.
- Support strategy: Powder‑based SLS eliminates the need for support structures, preserving surface finish on complex geometries.
- Post‑processing workflow: Recommended tumble media – 100 µm aluminum oxide – for surface smoothing; part integrity remains intact due to the polymer’s impact resilience.
- Safety: PA‑11 is FDA‑compliant for limited food‑contact and medical‑device prototyping (subject to final certification).
Bottom Line
Formlabs’ Nylon 11 Pro Powder delivers a compelling blend of flexibility, impact resistance, and dimensional stability that surpasses the capabilities of the long‑standing Nylon 12 material. By maintaining the same 30 % refresh rate and offering comparable pricing, it integrates seamlessly into existing Fuse 1+ workflows while opening new design possibilities for functional prototypes, end‑use parts, and medical‑grade devices. The upcoming Fuse X1 support in early 2027 further future‑proofs the investment, positioning
