→ What is Multi Jet Fusion 3D Printing?

Multi Jet Fusion is an industrial 3D printing process that produces functional nylon prototypes and end-use production parts in as fast as 1 day. Final parts exhibit quality surface finishes, fine feature resolution, and ‬more consistent mechanical properties when compared to processes like selective laser sintering.

Common applications for Multi Jet Fusion are:

  • parts requiring consistent isotropic mechanical properties
  • functional prototypes and end-use parts
  • complex and organic geometries with fine features

Design Guidelines for Multi Jet Fusion

Our basic guidelines for Multi Jet Fusion include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time. ​

  US Metric
Maximum Part Size 11.1 in. x 14.9 in. x 14.9 in 284mm x 380mm x 380mm
Layer Thickness 0.00315 in. 80 microns
Minimum Feature Size 0.020 in. 0.5mm
Wall Thickness 0.020 in. 0.5mm


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.

MJF Material Options

PA 12 Black

PA 12 Black is a high tensile strength nylon. Final parts are dyed black, and they exhibit quality surface finishes and slightly more isotropic mechanical properties when compared to SLS. When more detail is required, PA 12 can achieve smaller minimum feature resolution (0.02 in) as compared to SLS materials (0.03 in). PA 12 Black is the best material option for designs that incorporate living hinges.

Primary Benefits​

  • Near isotropic mechanical properties
  • Economical material choice

 

PA 12 40% Glass-Filled Black

PA 12 40% Glass-Filled Black is a 40% glass-filled nylon. Final parts are dyed black. The biggest advantage offered by this material is heat deflection at 347°F (measured at 66 psi), ranking 2nd best after PA 12 Mineral-Filled.

Primary Benefits​

  • Economical material choice
  • Heat deflection

These figures are approximate and dependent on a number of factors, including but not limited to, machine and process parameters. The information provided is therefore not binding and not deemed to be certified. When performance is critical, also consider independent lab testing of additive materials or final parts.

Multi Jet Fusion Surface Finish

   
Standard  A bead blast removes all powder and leaves a consistent overall texture. Parts are then dyed a standard black color.
Custom Secondary options include a primer that can be applied as well as taps and inserts.  

Our MJF 3D Printers

We use HP Jet Fusion 3D 4210 and 5210 machines that are capable of accelerated build speeds when compared to other powder-based additive manufacturing technology. The HP 3D printers produce commercial-grade parts with enhanced surface finishes and improved mechanical properties compared to other 3D printing technology.

Why Use Multi Jet Fusion?

See how 3D printing with Multi Jet Fusion is ideal for functional prototypes and end-use, production parts.

How Does Multi Jet Fusion Work?

Multi Jet Fusion uses an inkjet array to selectively apply fusing and detailing agents across a bed of nylon powder, which are then fused by heating elements into a solid layer. After each layer, powder is distributed on top of the bed and the process repeats until the part is complete.

When the build finishes, the entire powder bed with the encapsulated parts is moved to a processing station where a majority of the loose powder is removed by an integrated vacuum. Parts are then bead blasted to remove any of the remaining residual powder before ultimately reaching the finishing department where they are dyed black to improve cosmetic appearance.

ProJet MJP 2500W Plus 3D Systems

Description

ProJet MJP 2500W Plus 3D printer by 3D Systems

Introducing the ProJet MJP 2500W Plus - a productive 3D printer

High-performance production of pure wax jewelry master molds for lost wax casting. The
ProJet MJP 2500W Plus is a wax 3D printer that burns 100% without ash, just like regular wax in traditional jewelry casting. The production of these jewelry stencils adapts to your workflow, printing from several small batches per day to larger high-throughput assemblies.

This affordable printer combines high speed with a large print volume of 294x211x144mm for high output of precise and thin 3D printed jewelry casting patterns.

Cast Quality

The ProJet MJP 2500W Plus prints from 100% VisiJet wax materials to create durable, high quality jewelry models that provide reliable casting with excellent results in traditional investment casting processes and equipment.

VisiJet wax materials melt in the same way as standard casting waxes, with zero ash content resulting in flaw-free castings. It is durable for fine detail machining and casting, and the high contrast colors make fine detail easy to visualize.

Digital jewelry casting workflow increases production flexibility

High productivity

With the ProJet MJP 2500W Plus printer, you will have high efficiency production of injection molding patterns from single-strip printing with fast printing foundry - from short runs to high productivity. With high print volume and 24/7 operation, this affordable printer's high performance means fast amortization and a high return on investment.

Streamline your workflow from 3D model to template with advanced 3D Sprint software capabilities, fast and versatile MJP print speeds, and removal of batch processing support to produce high-quality cast-ready jewelry pieces.

Fast iterations, high productivity - for individual or mass production of jewelry

High detail wax templates

Seamlessly print CAD jewelry patterns with excellent feature reproduction, fine even sharp edges and extremely fine detail. Excellent resolution and soluble and consumable substrates provide excellent surface quality, reducing labor costs for finishing and polishing high-value precious metals. These high-precision, thin wax models are printed directly, without the time, wastage, and geometric constraints associated with tools.

High quality and high speed printing in XHD or ZHD mode for the smoothest surfaces with 2x vertical resolution

3D printers - heralds of a new industrial revolution at the Morgan Stanley Technology, Media and Telecom conference.

Sales of HP's first 3D printers will begin this year, Katie Lesjak, the company's chief technology officer, said during a speech at the Morgan Stanley Technology, Media and Telecom conference.

HP first announced 3D printers in 2014 and is now gearing up for a massive launch. In connection with entering a new market, the company is hiring material experts, mechanical engineers, managers and sales agents.

HP has a wealth of experience in printing hardware and is now tapping into a 3D printing market that has suffered from technical and hardware support issues in its more than twenty years of history. HP wants to offer businesses 3D printing that will be faster and cheaper.

“We are not interested in consumer 3D printing,” Lesjak said. “We will be doing business.”

What are the benefits of a 3D printer for a business? Instead of using multiple machines to make a product, Lesjak says all of its parts can be printed on the same 3D printer.

Companies will be able to reduce production costs by manufacturing products at their own facilities. And with the ability to print parts as needed, you won't have to stockpile excess inventory.

NASA uses 3D printers to make rocket engines, and commercial companies use them to make auto parts and medical equipment.

HP engineers want to offer a complete toolkit for creating three-dimensional objects that can be designed on a special Sprout computer system. In addition, the company wants to provide the ability to print 3D objects from virtual worlds.

The HP 3D Printer will be based on multi-inkjet technology, which combines a traditional 3D printing system with innovative techniques to work with new types of materials. During the printing process, the object is formed from the material in layers with the help of a binder that enters through the nozzle of the print head. The object is heated to cure, then a different material is applied to the finish. This process is repeated many times.

The HP printer will be able to work with specialized inks and materials. It will use the precision manufacturing methods used in the manufacture of integrated circuits, the company said.

3D printing technologies at HP are handled by the PageWide division, which produces printing presses.
