MJF | Multi-Jet Fusion

Multi Jet Fusion (MJF) is a 3D printing technology that produces multiple parts quickly using production thermoplastic materials for both prototypes and production parts. Its speed and material costs offer a viable method for small lot production without the cost of tooling. We use state-of-the-art HP 3D printers to give you optimal results for your projects.

Functional Prototypes and End-Use Production Parts

MJF has revolutionized how we approach rapid prototyping and production manufacturing. It’s fast, incredibly flexible, and ideal for creating complex geometries that traditional methods struggle to replicate. Ready to build your prototype or get fast production with MJF?

Applications

Rapid Prototyping

When you need a prototype, MJF is the ideal solution for quickly producing highly detailed parts.


Short Run Production

Get the parts you need faster, minimizing costs without extra post-production processes.


Manufacturing Fixtures

MJF is cost-effective, durable, and precise, making it an excellent option for manufacturing fixtures and jigs.

What does MJF feel like?

Multi Fusion Technology creates highly detailed parts. When taken out of the machine, the parts have a grey, chalk-like graininess, and the material color is naturally gray or can be dyed black. There are finishing options available to smooth and seal the parts. Our most popular option is Vaporsmooth, a chemical vapor process that smooths out surface roughness while maintaining intricate details. This process creates a glossy finish that resembles injection-molded parts, without the high cost.

Muti-Jet Fusion Finishes

The standard condition of parts after removal from the MJF machine appears as a faded gray with mat texture. SICAM takes it a step further. Parts go through our patented SHOTSHEEN™ process for more professional, quality parts. We also offer VAPORSMOOTH for sealing and smoothing parts, and CERAKOTE that provides a wide range of colors, as well as an option for a coating designed to provide a high-quality and long-lasting finish for parts requiring electrical insulation or ESD.

MJF FAQs

What is the largest part that can be made with MJF
The max build size for the machine is 14.96 x 11.18 x 14.96" But as with other processes, it may be possible to split large parts into smaller ones to fit the build volume.
What is the minimum recommended wall thickness for MJF parts?
The minimum recommended wall thickness is 0.02", but thicker walls can achieve better mechanical properties
What are the options for post-processing Multi Jet Fusion parts?
Post-processing options include Shotsheen for a smooth finish, Dyeing for a uniform black finish, Vapor smoothing for enhanced surface quality, and Cerakote for added functionality (e.g., temperature, chemical, and UV resistance) and color customization. Discuss options during ordering to meet specific aesthetic or functional needs.
What information should I provide when placing an order for Multi Jet Fusion parts?

To ensure optimal results, provide detailed CAD files (STL or STEP), specify material type, desired surface finish, tolerances, and any post-processing requirements. Including information about the part’s application (e.g., mechanical stress, temperature exposure) can help in optimizing production parameters.
