What are the differences between MJF-PA12 Nylon and SLS-3201PA-F Nylon

1. 3D Printing Technology

● MJF-PA12 Nylon:

○ Technology: Multi Jet Fusion (MJF) by HP.

○ Analysis: MJF technology uses fusing agents and detailing agents to precisely heat and melt powder layers, allowing for rapid printing of high-resolution and detailed parts.

● SLS-3201PA-F Nylon:

○ Technology: Selective Laser Sintering (SLS).

○ Analysis: SLS technology uses a laser to sinter nylon powder layer by layer, making it suitable for parts with complex geometries and widely used in industrial and manufacturing settings.

2. Surface Quality

● MJF-PA12 Nylon:

○ Surface: Grainy.

○ Analysis: Although the surface can be grainy, MJF technology typically provides smoother surface quality, suitable for applications requiring high visual quality.

● SLS-3201PA-F Nylon:

○ Surface: Grainy & Textured.

○ Analysis: SLS prints have a rougher surface texture, often requiring post-processing to improve surface finish, making it suitable for complex internal structures where surface smoothness is not a priority.

3. Accuracy

● MJF-PA12 Nylon:

○ Accuracy: ±0.3mm (within 100mm), ±0.4% (above 100mm).

○ Analysis: MJF technology offers high accuracy, making it suitable for producing parts with high precision and complex details.

● SLS-3201PA-F Nylon:

○ Accuracy: ±0.2mm (within 100mm), ±0.3% (above 100mm).

○ Analysis: SLS technology also provides high accuracy.

4. Tensile Strength

● MJF-PA12 Nylon:

○ Tensile Strength: 48 MPa.

○ Analysis: High tensile strength makes it suitable for parts that need to withstand mechanical stress.

● SLS-3201PA-F Nylon:

○ Tensile Strength: 44 MPa.

○ Analysis: Slightly lower tensile strength than MJF-PA12 but still suitable for functional and durable parts.

5. Elongation at Break

● MJF-PA12 Nylon:

○ Elongation at Break: 15%-20%.

○ Analysis: Provides moderate flexibility and toughness, allowing parts to bend without breaking.

● SLS-3201PA-F Nylon:

○ Elongation at Break: 35%.

○ Analysis: Higher elongation at break indicates better flexibility, making it suitable for applications requiring higher ductility.

6. Flexural Modulus

● MJF-PA12 Nylon:

○ Flexural Modulus: 1800 MPa.

○ Analysis: Higher flexural modulus indicates good rigidity and mechanical stability.

● SLS-3201PA-F Nylon:

○ Flexural Modulus: 1300 MPa.

○ Analysis: Slightly lower flexural modulus than MJF-PA12 but still provides sufficient mechanical performance for many industrial applications.

7. Heat Deflection Temperature

● MJF-PA12 Nylon:

○ Heat Deflection Temperature: 175°C.

○ Analysis: High heat deflection temperature makes it stable in high-temperature environments.

● SLS-3201PA-F Nylon:

○ Heat Deflection Temperature: 147°C.

○ Analysis: Slightly lower than MJF-PA12 but still suitable for applications requiring heat resistance.

8. Colors

● MJF-PA12 Nylon:

○ Colors: Natural Gray/Dyed Black.

○ Analysis: Default colors are natural gray or dyed black, suitable for applications requiring color customization.

● SLS-3201PA-F Nylon:

○ Colors: Black.

○ Analysis: Default color is black, but it can also be dyed to achieve other colors, suitable for various application scenarios.

9. Build Time

● MJF-PA12 Nylon:

○ Build Time: 72 hours.

○ Analysis: The build time is longer, but MJF technology achieves high-resolution and high-precision results, suitable for small to medium batch production.

● SLS-3201PA-F Nylon:

○ Build Time: 48 hours.

○ Analysis: Shorter build time makes it suitable for rapid turnaround and larger volume production.

Summary

MJF-PA12 Nylon is ideal for applications requiring high surface quality, precision, and mechanical strength, such as detailed and functional parts, despite its longer build time.

SLS-3201PA-F Nylon is suitable for parts with more complex geometries and larger production volumes, offering good flexibility and durability, with a shorter build time suitable for projects needing quick turnaround.
