Multi Jet Fusion (MJF)

Multi Jet Fusion (MJF) Services in Canada

HP Multi Jet Fusion (MJF) is the high-throughput cousin of SLS. A thermal print head deposits fusing and detailing agents on a powder bed, then infrared lamps fuse the treated areas. The result: production-grade nylon parts with isotropic mechanical properties, finer surface finish than SLS, and significantly faster build times for high-volume orders. Canadian MJF capacity has expanded rapidly to support consumer products, automotive, and industrial low-volume manufacturing.

Multi Jet Fusion (MJF) 3D Printing in Canada

HP Multi Jet Fusion is one of the fastest-growing 3D printing processes in Canada. The high-throughput print model — fusing entire layers in seconds with a thermal print head and IR lamps — makes MJF particularly economical for full-build-chamber production runs. Canadian service bureaus running HP 5200-series machines have rapidly displaced both SLS and short-run injection molding for many nylon applications.

Where MJF Wins

Production-volume nylon parts. When you need hundreds to thousands of parts per month, MJF’s build speed and density makes it economically competitive with injection molding for many programs.

Functional consumer products. Sports gear, footwear components, custom-fit accessories, and aftermarket products all benefit from MJF’s combination of strength, geometric freedom, and economical production.

Low-volume automotive and industrial. End-use parts with complex geometry, multi-functional assemblies, and short-life production runs.

Replacement and aftermarket parts. Out-of-production OEM nylon parts can be reverse-engineered and produced economically without tooling.

For some applications, either works. For higher volumes of PA12, MJF tends to win on lead time and price. For specialty materials (FR, bio, filled grades), SLS often has the broader catalogue.

Canadian MJF Network

MJF capacity is concentrated near major service-bureau clusters in Ontario, Quebec, and BC. We route based on the build chamber size needed (HP 4200, 5200, or 5210 platforms have different cost-per-cubic-mm), material, and finishing requirements.

Frequently Asked Questions

How is MJF different from SLS?
Both fuse nylon powder. [SLS](/manufacturing/3d-printing/sls/) uses a laser; MJF uses a thermal print head with fusing and detailing agents and infrared fusing. MJF is typically faster (3–10x build speed for full chambers), produces slightly finer surface finish, and has narrower material range. SLS has been the workhorse longer with broader certification. For higher volumes, MJF often wins. We route based on quantity, material, and lead time.
What's the surface finish of MJF parts?
MJF parts have a fine, slightly grainy as-printed finish — typically smoother than SLS but still grainy compared to injection molded or SLA parts. Black-dye is standard (the detailing agent absorbs IR and fuses the part with built-in dark coloration). Bead-blasted MJF parts are paint-ready. Vapor-smoothing produces near-injection-molded surface quality.
Can MJF replace injection molding for low-volume production?
For PA12 nylon parts in volumes up to roughly 5,000–20,000 units per year, MJF is increasingly competitive with injection molding — especially when geometry is complex or the program needs design flexibility. Beyond that volume, injection molding wins on per-part cost. We model both options on real production programs.
Is MJF suitable for medical and aerospace applications?
Yes — biocompatible PA11 and PA12 grades are available, and ISO 13485 / AS9100 Canadian shops can produce qualified MJF parts. Material certifications and traceability are part of the standard quote process at certified shops.
