PA12 vs PA11 vs PA-GF – Material Comparison for Industrial 3D Printing in Europe
Compare mechanical properties, surface quality, lead time, and best-use cases for SLS 3D printing materials.
Quick Decision Guide
PA12 offers the best balance of strength and flexibility for general-purpose functional prototypes, with the fastest lead times and most economical pricing across EU production.
PA11 provides superior impact resistance and higher heat deflection temperature, making it ideal for automotive under-hood components and parts requiring long-term mechanical stability.
Glass-Filled Nylon delivers maximum stiffness and dimensional stability at elevated temperatures, best suited for industrial jigs, fixtures, and structural components where rigidity is critical.
⏱️ EU Lead Time Range: 3-7 business days depending on material selection and part complexity.

- Manufacturing jigs and fixtures
Cost & Production Context
Material Cost Impact
Material selection affects part pricing by 15-40%. PA12 offers the most economical option, while specialized materials like Glass-Filled Nylon command premium pricing due to enhanced performance characteristics.
Production Time
Lead times vary by material availability and post-processing requirements. Standard PA12 typically ships in 3-5 days, while specialized materials may require 5-7 business days for EU delivery.
Finishing Options
All SLS materials support vapor smoothing, dyeing, and coating. PA12 and PA11 achieve better cosmetic finishes than Glass-Filled variants due to their smoother base surface texture.
