Aluminum-Filled Alumide Nylon 12

Our SLS Aluminum-filled Material

When your 3D printed parts need to look and act like metal without the backbreaking weight or eye-watering price tag, Nylon 12 Alumide steps up as your ultimate sidekick. By blending tough polyamide 12 with fine aluminum powder, this laser-sintered material delivers exceptional structural stiffness, high heat deflection, and crisp dimensional accuracy so your jigs, fixtures, and enclosures never sag under stress. Need polished surfaces or custom machining? No problem. The metal-infused composite sands, drills, and finishes effortlessly, giving you the sleek aesthetic of aluminum paired with the complex geometric freedom of selective laser sintering. It is the ultimate shortcut for turning demanding functional prototypes into durable, production-ready components—making you look like an absolute engineering genius who somehow stayed way under budget.

Alumide Features

  • Metallic Gray
  • High stiffness
  • Superior dimensional accuracy
  • Good thermal conductivity
  • Aluminum powder creates a product that is somewhat brittle — not recommended for structural applications
  • Easy post processing via machining, grinding, and milling
  • Secondary polishing processes provides a surface with a metallic-looking finish
  • WARNING! This product should not be used in any application where contact with foodstuffs would be possible

Choosing Your 3D Printing Champion

Picking the right material shouldn't feel like a chemistry quiz, so let's break down the two heavyweights of SLS printing. If you need parts that bend but refuse to break, meet Nylon 11. Born from castor oil—yes, you get green bragging rights—this eco-friendly powerhouse offers incredible impact resistance, making it your go-to for living hinges and high-pressure environments. On the flip side, Nylon 12 is the reliable industry baseline synthesized from petrochemicals. It trades flexibility for rigidity, delivering rock-solid dimensional stability that makes it perfect for complex housings, rugged enclosures, and economical production runs.
