About this resource

This guide compares Multi Jet Fusion (MJF) and Selective Laser Sintering (SLS), two leading industrial powder bed fusion 3D printing technologies. MJF, developed by HP, uses fusing and detailing agents with infrared heating to produce smooth, accurate parts quickly. SLS, pioneered by 3D Systems, uses a high-powered laser to sinter polymer powders, delivering strong, complex parts with broad material options.

Key Takeaways

  • MJF excels in high-volume production, faster turnaround, smoother surfaces, and lower post-processing.
  • SLS offers superior mechanical strength, larger build volumes, greater material versatility, and better suitability for complex geometries.
  • Both technologies are ideal for functional prototypes and end-use parts, but the best choice depends on volume, part size, material requirements, and budget.

When to Choose Each Process

Choose MJF when you need many identical parts quickly with minimal finishing, such as consumer products, automotive interior components, medical devices, and bridge production.

Choose SLS when mechanical performance, material variety, large parts, or intricate internal features are critical, such as aerospace brackets, automotive under-the-hood parts, industrial fixtures, and custom wearables.
