What is MJF Printing?

MJF is a powder bed fusion technology developed by HP. It selectively sprays the bonding agent and the fining agent through an inkjet array, and combines infrared heating to rapidly melt the nylon powder, achieving high-precision mass production. Its core advantages lie in:

Industrial-grade efficiency:

Full-layer synchronous curing, printing speed is 10 times faster than SLS, supports continuous batch manufacturing

Excellent precision:

Achievable tolerance of ±0.2mm, with excellent surface quality (Ra 8-12μm)

The material has excellent properties:

Using materials such as PA12/fiber-reinforced nylon, its mechanical performance is comparable to that of injection-molded parts.

Cost advantage:

Reduces costs by 50% compared to traditional CNC processing, particularly suitable for small and medium batch production.

Core advantages of MJF printing

Industrial-Grade Production Efficiency

Featuring whole-layer synchronous curing technology, delivering 10x faster printing speed than traditional SLS, enabling single-batch production of 500+ parts.

Injection-Molding-Level Precision

±0.2mm dimensional tolerance with Ra8-12μm surface finish, supporting 0.5mm thin-wall structures.

Exceptional Functional Performance

Utilizes PA12/PA11 and glass-fiber reinforced materials with tensile strength up to 48MPa, capable of replacing injection-molded end-use parts.

Superior Cost Efficiency

50% cost reduction compared to CNC machining, with progressively lower unit costs for small-batch production.

The MJF Process Overview

Qiying adopts a full-process digital control system to ensure that every step from the document to the final product complies with the ISO 9001 quality standards, providing customers with high-precision and highly consistent SLA printing services. A Comprehensive Analysis of the Entire Process of SLA Light-Curing 3D Printing:

Powder Bed Deposition

The robotic arm uniformly spreads a 0.08mm layer of nylon powder in the build chamber, preheated to 180°C (near material melting point).

Intelligent Jetting

An array of 15,600 nozzles operates synchronously, precisely depositing fusing agent (activator) and detailing agent (inhibitor), with each layer completed in just 5-8 seconds.

Infrared Fusion

High-power IR lamps (2,800W) scan and irradiate, instantly heating jetting areas to 200°C for fusion, while non-irradiated zones remain in powder state.
