The most popular resin that is characterized by stiffness.
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?
High resolution and dimensional accuracy of 3D printing thanks to the ultra-thin layer thickness (from 16 µm)
Possibility to produce multi-material and multi-colored parts
Material variety (from rubber-like materials to hard materials)
Relatively easy post-processing - supporting structures removed with a water jet
Standard resin - Product description
Resins imitating the properties of engineering material: ABS-like, PP-like - Product description
The mechanical properties of these resins are similar to those of ABS and PP.
Flexible resin - Product description
Resin with properties similar to rubber.
High-temperature resin - Product description
Resin designed for applications operating at higher temperatures (up to 80 °C).
Super clear resin - Product description
The material is designed for applications where high transparency is required. Possible further processing which allows for almost 100% transparency.
Dental/medical resin - Product description
Resin used in medicine. It has a biocompatibility certificate.

Resin technologies design guidelines
With For PJ / MJM technology, we recommend that you follow these recommendations:
Minimum hole diameter 2 mm
Minimum wall thickness from 0.6 mm depending on the geometry
The access to areas with a bottom bracket should be secured in order to remove it
Positioning pins should be at least 2 mm thick/medium
