Quick Specifications


Technology Overview
High-Speed Production 3D Printing
MJF combines speed with quality through parallel processing technology. Ideal for rapid prototyping and scalable production with consistent mechanical properties and excellent surface finish.
Advanced manufacturing capabilities enable complex geometries, functional prototypes, and end-use production parts that would be impossible or cost-prohibitive with traditional manufacturing methods. From functional prototypes to end-use production parts, this technology delivers exceptional performance across demanding industries.
Production Applications
1 to 1000+ Parts Built in Hours
Engineered for high-volume production with consistent mechanical properties across thousands of parts, MJF technology delivers production-grade components with excellent surface finish and dimensional accuracy. The thermal fusion process enables rapid part consolidation with up to 80% powder reusability, making it cost-effective for batch production. Industries rely on MJF for functional prototypes, end-use parts, and custom manufacturing where speed and consistency are critical.
End Use Parts for High-Performance Applications
Production workflows benefit from MJF's unique ability to nest hundreds of parts efficiently within each build, maximizing throughput while maintaining consistent quality. The thermal inkjet process applies fusing and detailing agents with precision, creating smooth surfaces and sharp edges without traditional support structures. Real-time monitoring and closed-loop control systems ensure every part meets stringent quality standards for batch production and regulatory compliance.

Applications:
Material Surface Finishes
MJF parts have a smooth, matte surface with a slightly grainy texture due to the powder-based printing process. Unlike FDM, MJF does not produce visible layer lines, resulting in a more uniform and professional appearance straight from the printer. At Forge Labs, bead blasting is performed as a standard post-processing step to remove excess powder and refine the surface texture.

Standard Finish
Natural Grey
MJF parts are delivered with a standard bead-blasted finish in natural grey. This process removes excess powder and slightly smooths the surface while maintaining the material's natural matte texture.
Finish Attributes


Deep Color Dye
Dyed Black
Specialized dye bath creates deep, uniform black color that chemically bonds with the nylon material. Unlike painted finishes, the dye fully penetrates the surface and won't chip or wear off over time.
Finish Attributes


Vapor Smoothing
Enhanced Finish
Advanced chemical smoothing technique that enhances surface quality by slightly melting and redistributing the surface material, eliminating grainy texture and sealing porous areas.
Finish Attributes

Performance Paint
Custom Finish
Automotive-grade coating that enhances aesthetics and durability. Hand-finished for smooth surfaces with professional-grade equipment. Custom color matching available for precise branding needs.

Multi-Jet Fusion Design Guidelines
Essential design considerations to optimize your Multi-Jet Fusion parts for manufacturing success.

Maximum Build Volume
380 x 284 x 380 mm (15 x 11.2 x 15 inches)
If your parts require specific tolerances, please include an engineering drawing along with the part. Parts designed with large flat planes will likely warp, so this should be avoided if tight tolerances are required.
Parts with large flat surfaces are prone to warping and should be avoided for applications requiring tight tolerances.

Tolerances
Nylon PA 12: ±0.3%, with a lower limit of ±0.5 mm
If your parts require specific tolerances, please include an engineering drawing along with the part. Parts designed with large flat planes will likely warp, so this should be avoided if tight tolerances are required.
Always provide engineering drawings for parts requiring specific dimensional tolerances.

Layer Height
100 Microns
The layer height is the overall Z resolution of the part; we avoid stepping artifacts on important features of your models by orienting the part(s) along the Z plane or at a 20 degree angle on all sides.
Optimal part orientation minimizes visible layer lines on critical surfaces.

Surface Finish
Uniform, Matte
Parts are bead blasted and have a uniform grainy matte texture, similar to ultra-fine sandpaper.
The matte finish provides excellent grip and professional appearance for functional parts.
