HP Multi Jet Fusion 3D Printing
Complex, Functional Prototypes and Production Parts
Highly accurate, extremely rugged end-use parts delivered fast
If your part requires consistent isotropic mechanical thermoplastic properties and/or complex geometries with fine features, then HP Multi Jet Fusion (MJF) technology may be ideal for your project. MJF technology produces thermoplastic parts with consistent isotropic properties and excellent accuracy. Parts produced have a smooth surface with almost invisible layers, and properties comparable to injection-molded parts.
The MJF process is cost-competitive for quickly producing low-to-medium volumes of rugged, highly detailed thermoplastic parts.
MFJ parts are fabricated with chemically resistant and extremely rugged Nylon 12 powder. The MJF build process begins by spreading a very thin layer of Nylon powder on the surface of the build plate. Using high-resolution inkjet technology, fusing and detailing agents are jetted into the powder to detail the part being created. An infrared light source sinters (melts) the powder that has been inked. As it cools and solidifies, the next layer of powder is spread over it. Each layer takes 16 seconds, regardless of the number of parts being produced. Build layers are approximately 0.004″.
Although MJF is similar to SLS (Selective Laser Sintering), there are key differences. MJF is extremely fast as compared to SLS. The edges and features of MJF parts are extremely sharp and accurately defined, as compared to SLA parts. MJF layer thickness, wall thickness, and feature resolution are all slightly better than with SLS technology. Because of the extremely high build efficiencies, MJF part price is typically less than parts produced with SLS. This is based on the high packing density that MJF offers. High numbers of parts can be built with MJF without increasing the build time. SLS technology offers a wider range of material options, however.
“I’ve waited over 20 years for 3D printing to get to this point.
Real thermoplastic parts that don’t break, assemblies that fit together, and production speeds that are incredibly faster. It’s what we’ve always hoped for.”
“Thank you again for pushing these parts through for us!
The whole team here is appreciative of InterPRO finishing up those parts ahead of schedule!”
“I got my parts on Saturday morning!
Thank you. Really great work you have done.”
“The team is thrilled with its appearance and with the results of your rework.
This model will do a great job helping us gain alignment between the industrial design, mechanical teams and our product managers. We really do appreciate the effort you had to go through to deal with this fire fight and look forward to working with you on future prints and models.”
