PJ (Poly Jet) / Multi Jet Modelling (MJM)

In resin technologies PJ (Poly Jet) and MJF (Multi Jet modeling) the processed material is a material in the form of a photosensitive resin. The polymerization process is carried out through the UV lamp energy which realizes the polymerization of selectively superimposed sections of the produced model. Resin technologies are used in a wide range of applications, e.g. automotive, biotechnology, medicine and jewelry. High precision of parts and a wide range of materials constitute additional advantages of these technologies. Advanced geometries require support structures that in most cases can be removed relatively easy with dissolution or rinsing. If support structures cause problems in your project, check out SLS.

What are the benefits of PJ / MJM?

Benefit #1

High resolution and dimensional accuracy of 3D printing thanks to the ultra-thin layer thickness (from 16 µm)

Benefit #2

Possibility to produce multi-material and multi-colored parts

Benefit #3

Material variety (from rubber-like materials to hard materials)

Benefit #4

Relatively easy post-processing - supporting structures removed with a water jet

Materials

Standard resin

The most popular resin that is characterized by stiffness.

Contact Your Specialist

Resins imitating the properties of engineering material: ABS-like, PP-like

The mechanical properties of these resins are similar to those of ABS and PP.

Contact Your Specialist

Flexible resin

Resin with properties similar to rubber.

Contact Your Specialist

High-temperature resin

Resin designed for applications operating at higher temperatures (up to 80 °C).

Contact Your Specialist

Super clear resin

The material is designed for applications where high transparency is required. Possible further processing which allows for almost 100% transparency.

Contact Your Specialist

Dental/medical resin

Resin used in medicine. It has a biocompatibility certificate.

Costs and Lead Time

What influences resin costs and lead time

  • Part capacity
  • Used material
  • Used parameters (e.g. layer thickness)
  • Bottom brackets - check other technologies without support
  • Production series size
  • Applied postprocessing - more information in postprocessing
  • Choosing express execution options

Resin technologies design guidelines

With For PJ / MJM technology, we recommend that you follow these recommendations:

Zasady druk 3D

Minimum hole diameter 2 mm

Zasady druk 3D

Minimum wall thickness from 0.6 mm depending on the geometry

Zasady druk 3D

The access to areas with a bottom bracket should be secured in order to remove it

Zasady druk 3D

Positioning pins should be at least 2 mm thick/medium
