SLS technology offers several unique advantages that bridge the gap between prototyping and mass production:

• No Support Structures Needed: Unlike FDM or SLA, SLS prints are supported by unsintered powder, making it ideal for complex geometries.
• Functional End-Use Parts: SLS materials provide mechanical strength close to injection molded plastics.
• Faster Production Turnaround: Multiple parts can be nested and printed in a single job. 
• Durable and Lightweight: Perfect for prototypes, pilot batches, or bridge manufacturing.

Nylon 12 (PA12)

• Properties: Excellent balance of strength, flexibility, and chemical resistance.
• Applications: Functional prototypes, automotive parts, snap-fits, enclosures.
• Why Choose It: It’s the industry standard for SLS and covers most general-purpose needs.

Nylon 11 (PA11)

• Properties: More ductile and impact-resistant than PA12; derived from renewable castor oil.
• Applications: Wearable products, orthotics, impact-resistant housings.
• Why Choose It: Ideal when flexibility or biocompatibility is required.

Glass-Filled Nylon (PA12-GF)

• Properties: Stiff, wear-resistant, and dimensionally stable.
• Applications: Jigs, fixtures, structural parts, under-the-hood components.
• Why Choose It: Great for applications requiring mechanical strength and minimal warping.

Carbon Fiber-Reinforced Nylon (PA12-CF)

• Properties: High stiffness-to-weight ratio, excellent dimensional stability, and heat resistance.
• Applications: Drone parts, lightweight brackets, structural supports, robotics frames.
• Why Choose It: Best for high-performance parts that require stiffness and heat resistance without adding weight.

Alumide (PA12 + Aluminum Powder)

• Properties: Metallic appearance with enhanced rigidity.
• Applications: Automotive prototyping, aesthetic mockups, heat-resistant housings.
• Why Choose It: When both surface appearance and mechanical stability matter.

Polypropylene (PP)

• Properties: Excellent chemical resistance, fatigue resistance, and low density.
• Applications: Containers, living hinges, fluid ducts, automotive tanks.
• Why Choose It: Ideal for chemical-sensitive applications or parts requiring ductility and repeated flexing.

TPU (Thermoplastic Polyurethane)

• Properties: Highly flexible, durable, and wear-resistant.
• Applications: Gaskets, seals, footwear, flexible joints.
• Why Choose It: Ideal for soft-touch or impact-absorbing parts.

To ensure successful production, keep these parameters in mind:

• Wall Thickness: Keep ≥ 1mm for PA12,PA11, GF, CF, ≥ 2mm for TPU or PP.
• Post-processing: SLS parts can be vapor smoothed, dyed, painted, or CNC post-machined.
• Tolerances: Typical tolerance is ±0.3 mm or 0.3% of part length. PA12-CF and PA12-GF offer best dimensional accuracy.
