HP MJF 3D Printing Services
HP Multi Jet Fusion (MJF) is an advanced powder bed fusion technology that produces high-precision, high-durability plastic parts at relatively high speeds. Compared to other powder fusion processes likeSelective Laser Sintering (SLS) or Direct Metal Laser Sintering (DMLS), MJF has clear advantages in forming efficiency and detail performance. This technology balances economy, speed, and resolution, suitable for direct manufacturing of low-volume end-use parts,Rapid Prototyping and design validation, as well as bridge manufacturing before injection molding. MJF allows engineers to understand part performance in advance at lower cost, providing a reference for subsequent mass production.

Applications for HP MJF
Concept Models
With MJF technology's high-speed response and detail capability, product developers can quickly obtain physical versions of design concepts for early validation and communication, with finished parts combining structural strength and fine detail.
Rapid Prototyping
The MJF process is suitable for manufacturing fully functional prototypes, which can include moving parts or integrated structures, meeting the practical needs of design iteration and functional testing.
Direct Digital Manufacturing
Multi Jet Fusion technology combines cost advantages with forming efficiency, making it an ideal choice for direct manufacturing of low-volume individual parts or customized products, capable of quickly responding to diverse production needs.
HP MJF Parts Vapor Smoothing Post-Processing
KH-TAT offers vapor smoothing surface treatment services that significantly improve the appearance and mechanical properties of 3D printed parts. This process uses AMT PostPro3D automated equipment for uniform surface treatment results. Combined with the cost advantages of HP MJF technology, vapor-smoothed parts can approach injection-molded part levels in both appearance and functional performance. After treatment, surfaces have a uniform, dense, semi-gloss texture, while also improving key performance metrics like ultimate tensile strength, flexural yield strength, and elongation at break. This post-processing is also suitable forSelective Laser Sintering (SLS) and Fused Deposition Modeling (FDM) process-made rigid plastic and elastomer parts, meeting application scenarios with higher surface quality and mechanical property requirements.
HP MJF Prototyping Tolerances
In the table below, you will find our standard MJF tolerances for prototype orders. These include one-off or first-time prints, non-production orders, and auto-quoted orders that have not received a manual engineering review.
MJF Prototype Tolerances Based on HP 5200-Series, Balanced Mode
| Material Type | Under 30 mm (1.2") | 30 - 50 mm (1.2" - 2.0") | 50 - 80 mm (2.0" - 3.2") | > 80 mm (3.2") |

HP Multi Jet Fusion (MJF) Technology Overview
HP MJF Technology Basics
HP Multi Jet Fusionis a high-performance 3D printing technology that produces high-precision, high-durability plastic parts, suitable for direct manufacturing of low-volume end products andRapid Prototyping. This technology borrows from mature 2D inkjet printing principles and has significant advantages in inter-layer forming speed compared to other powder bed fusion processes.
How Multi Jet Fusion Technology Works
Like all powder bed-based 3D printing processes, Multi Jet Fusion builds layer by layer, using fusing agents and heat to solidify each layer of powder before spreading a new layer.
In traditional powder fusion processes like Selective Laser Sintering (SLS), Stereolithography (SLA), or Direct Metal Laser Sintering (DMLS), a single laser typically scans point by point, making the imaging process for each part relatively time-consuming. while HP Multi Jet Fusion's How It Works is more like inkjet printing, where the print head can deposit fusing agent across the entire build area in one pass, enabling simultaneous forming of multiple parts and greatly improving production efficiency.
Core Advantages of HP Multi Jet Fusion Technology
HP Jet Fusion technology demonstrates unique advantages in multiple aspects. Its standard forming parameters are optimized for high density, giving formed parts good sealing performance.
If you're familiar with the SLS process and want to improve low-volume production efficiency, Multi Jet Fusion is worth considering. This technology can print multiple parts simultaneously across the entire build volume, with forming speeds several times faster than SLS and other processes. Additionally, compared to SLS, MJF achieves more balanced mechanical performance across X, Y, and Z directions.
For products planned for injection molding, making 3D printed test parts before investing in metal molds is an effective way to reduce risk. While the SLA process can achieve extremely high detail precision, its photopolymer resin lags behind traditional thermoplastics in toughness and may experience performance degradation under UV and humid environments.
In contrast, Multi Jet Fusion technology maintains high precision while preserving the structural durability of traditional thermoplastics, especially when using glass fiber reinforced nylon materials. This makes MJF an ideal choice for validating part assembly and functionality before injection molding.
