What is Material Jetting?

Material Jetting (MJ), otherwise known as Polyjet or Binder Jetting, is an ultraviolet-sensitive gel deposited by a print head and immediately cured by a UV lamp. The machine can use rigid and rubber-like materials and has an excellent surface finish.

Material jetting 3D printing is a solution for designers who want excellent visual models with an end-product feel. This technology can incorporate multiple materials and colors into one print. It is suitable for complex, flexible models.

How does Material Jetting work?

Our AM Technician takes your CAD file and uploads it into the machine. The software breaks it down layer by layer. We also consider the direction of the build and the placement of the supports. The Material Jetting machine sprays extremely fine layers of tiny droplets in the shape of the part from a printhead nozzle that are instantly cured with a UV light. Material Jetting 3D printing can use multiple materials and colors.

Once finished, the part coated in the support material, a combination of glycerin, polyethylene, and propylene, while the build is removed using a chemical solution bath and pressurized water stream.

Material Jetting materials at Midwest Prototyping

Material Jetting is the only industrial 3D printing technology that can print multiple materials simultaneously.  This process allows for combining flexible and rigid materials, over-molds, and numerous colors.   Picture a transparent human heart model with colored materials marking the arteries, atriums, veins, and ventricles that show blood flow.  Since the materials are UV-cured, they cannot withstand prolonged exposure to light or heat without becoming discolored.  Parts made by using Material Jetting should not be used in rugged environments.



Key Characteristics

More Information

Agilus30 is a photopolymer with excellent flexibility and tear resistance and can withstand repetitive bending and flexing due to its rubber-like qualities.

  • Flexible

Tango Black is a flexible photopolymer that can simulate thermoplastic elastomers with elastic, rubber-like qualities.

  • Elastomeric
  • Flexible

Vero Clear is a transparent photopolymer that simulates acrylic and can be used as an alternative to glass.  Vero Clear can also combine it with colors to create various transparent colored lenses. 

  • Clear/ Translucent
  • High Resolution/High Detail
  • Rigid

Vero Family 

Vero Black+ and Vero White+

The Vero Family is a photopolymer offering multi-color applications, strength, and stiffness. Photopolymers may be blended with other photopolymers to vary flexibility, translucency, and heat resistance. 

  • High Resolution/High Detail
  • Rigid

Material Jetting finishing levels at Midwest Prototyping





Supports removed

Standard finish: supported surfaces appearing matte and non-supported surfaces appearing glossy. Parts will have slight layer lines.


Part built using matte build settings and supports removed

Standard finish: parts built surrounded in support. All surfaces appear matte. Parts will have slight layer lines.


Supports removed and cosmetic surfaces sanded to 320 grit

Show quality finish: removes layer lines. Parts are prime and paint ready.


Supports removed and cosmetic surfaces wet sanded to 600 grit

High gloss finish: recommended only for plating and optically clear parts (note that clear-coat and light bleaching is necessary for optimal clarity).

* Elastomeric materials can only be finished to Level 1 and Level 2. For a higher quality finish, these materials may be coated in soft touch.
