MJF printing

Xunjie provides professional MJF manufacturing services for customers who need durable, production-grade nylon parts. We use HP Multi Jet Fusion technology and high-quality PA12 nylon material. These are suitable for functional components, end-use parts, and engineering parts. We support prototype validation and low-volume manufacturing.

• High strength and durability, suitable for end-use parts.
• Surface quality close to injection molded parts, ready for assembly.
• Supports batch production of complex internal structures. Complex assemblies can be formed in one print.

Why You Can Trust Xunjie 3D Printing

• Over 10 years of 3D printing experience, familiar with HP MJF process and various nylon materials  
• Certified with CE, ISO 9001, RoHS, SGS and more  
• Over 200 advanced 3D printing machines, supporting MJF batch production  
• Free design optimization services, quality guaranteed, free redo if issues occur

Production-Grade Mechanical Properties

HP PA12 is one of the most widely used engineering-grade nylon materials in additive manufacturing. PA12 HP nylon offers excellent impact resistance, wear resistance, and fatigue performance. This makes it suitable for functional nylon parts that need to withstand repeated loads and daily use.  

Customers often use our MJF PA12 parts as end-use products, not just temporary prototypes. These nylon parts can be directly assembled into commercial products, industrial systems, and mechanical equipment without additional mold investment.

More Cost-effective 

Injection molding is only economical at very high volumes.For quantities between 50 and a few thousand pieces, mold costs often make injection molding expensive and inflexible.  

Our MJF batch production service eliminates molds completely.  

This allows you to:  

• Launch products faster  
• Reduce upfront investment  
• Avoid mold modification costs  
• Produce multiple design variations at the same time  
• Respond quickly to market demand changes

Support Mass Production

Xunjie has over 200 various 3D printing machines, with sufficient capacity and the ability to flexibly handle orders ranging from single prototypes to thousands of pieces per batch.

During small-batch manufacturing, MJF does not require molds, and the cost and time advantages are obvious. Even for large-volume orders, our optimized nesting system ensures consistent quality across hundreds or thousands of parts.

You can start testing designs and market feedback with small batches, and then smoothly transition to mass production. Throughout the process, you don't need to change suppliers.

Applications of HP nylon parts

Our HP PA12 parts are widely used in low-volume manufacturing, MJF batch production, and end-use product applications. MJF nylon parts offer excellent strength, dimensional accuracy, and design flexibility. They are an ideal choice for functional nylon parts in industries such as automotive, industrial, consumer goods, and robotics.

Automotive parts  

HP PA12 parts are widely used for brackets, clips, air duct systems, cable routing components, and custom vehicle accessories.The strength and heat resistance of MJF PA12 make it suitable for demanding automotive environments.

Industrial manufacturing  

MJF nylon parts are very suitable for making jigs, fixtures, machine housings, tooling aids, and replacement parts. HP multi jet fusion materials offer excellent wear resistance and durability.

Consumer goods

HP nylon parts achieve a good balance between strength, appearance, and cost efficiency. They are suitable for smart device housings and wearable product components.

Robotics and automation  

Functional nylon parts made with MJF technology are commonly used in robotic systems, automation equipment, and custom engineering assemblies. In these applications, light weight is very important.

FAQ

1、Can MJF parts be used as end-use products?  

Yes, absolutely. MJF HP PA12 parts are not just for prototypes. They are also suitable for functional end-use applications. The high tensile and flexural strength of MJF PA12, along with its uniform mechanical properties, allow it to replace traditionally manufactured parts in assemblies. It is very suitable for consumer electronics housings, industrial brackets, and automotive parts. In addition, the chemical resistance, wear resistance, and heat resistance of HP MJF parts ensure durability even in harsh environments.

2、Can you provide black nylon parts or other color options?  

Yes. HP PA12 parts are black or white by default. Xunjie offers one-stop post-processing services. If you need custom colors, we can paint the parts for you. Thousands of Pantone colors are available for you to choose from. We can also provide gloss, matte, or textured finishes. Painting costs are quoted based on the surface area and difficulty of the nylon parts, with clear and transparent pricing.

3、Is MJF suitable for batch production?

MJF is extremely suitable for batch production. This technology was specifically designed for efficient batch production. It can densely arrange parts within the printing chamber while maintaining consistency in performance. Our production process ensures that hundreds of parts in the same batch have uniform mechanical properties and dimensional accuracy. Therefore, MJF is especially suitable for small to medium batch manufacturing and short-run production, with no worries about part quality.

4、Do you offer design support?

Yes, we do. Xunjie has its own model design team. You send your drawings to us, and our engineering team can provide free design optimization to help you improve the manufacturability of the model, reduce costs and enhance the performance of the parts. You don't need to seek help from others to modify the drawings anymore.

5、Will my design be kept confidential? Can we sign a non-disclosure agreement?  

Absolutely confidential! This is a basic service principle of Xunjie Technology. We will not disclose your design files or models to anyone, nor will we use them for any commercial purposes. If you need it, our company can sign a formal non-disclosure agreement with you, with our company seal, to protect your intellectual property.
