Multi Jet Fusion (MJF) is an industrial-grade 3D printing technology that delivers functional nylon prototypes and end‑use production parts in as fast as one day. Compared to processes such as selective laser sintering, MJF‑produced parts deliver superior surface finishes, finer feature resolution, and more consistent mechanical properties across the build.
Why Use MJF 3D Printing?
Choosing MJF (Multi Jet Fusion) 3D printing services delivers powerful advantages for industrial prototyping and end‑use production. It offers extremely fast turnaround, producing functional nylon parts in as fast as one day, helping teams accelerate product development and time‑to‑market. MJF excels in surface quality, fine feature resolution, and consistent mechanical properties—often outperforming processes like SLS in uniformity and detail.
The technology supports high‑efficiency nesting of multiple parts in a single build, maximizing throughput and lowering per‑unit costs. It works with high‑performance nylons, creating durable components with excellent strength, heat resistance, and dimensional stability. With minimal post‑processing and reliable batch production, MJF is a cost‑effective, versatile solution for both low‑volume prototypes and higher‑volume production runs.
Design Guidelines
We don't have MOQ, only 1pcs is according to high standard to make, we pursuit the product is perfect to every customer, from 1pcs to million,we are glad to witness and grow together with our customers, that make us proud.
Our basic guidelines for Multi Jet Fusion include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.
Tolerances: For well-designed parts, tolerances of +/- 0.012 in. (0.30mm) plus 0.1% of nominal length for each additional inch can typically be achieved. Note that tolerances may change depending on part geometry.
Warpage: Larger part sizes (>7 in.) and parts with thin features are the most susceptible to warp. We recommend maintaining a uniform thickness of 0.125 in. (3.175mm) to ensure stability.

Surface Finish Options
✔️ Standard
Bead blasting effectively removes all residual powder and creates a uniform, consistent surface texture across the part. After blasting, parts are dyed to a standard black finish for a clean, professional appearance.
✔️ Vapor Smoothing
Surface smoothing significantly reduces roughness from over 250 μin RA in the as‑printed state to 64–100 μin RA after treatment. This enhanced finish is available for PA12 Black parts.
✔️ Custom
Secondary finishing options include primer application, as well as the installation of threaded taps and inserts.
How Does Multi Jet Fusion Work?
Multi Jet Fusion (MJF) uses an inkjet array to selectively deposit fusing and detailing agents across a bed of nylon powder. Heating elements then fuse the treated areas into a solid layer. After each layer, fresh powder is spread over the bed, and the cycle repeats until the part is fully built.
Once printing is complete, the entire powder bed containing the parts is transferred to a processing station. An integrated vacuum removes most loose powder, followed by bead blasting to eliminate any remaining residue. Parts are then sent to the finishing department, where they are dyed black to enhance cosmetic appearance.
