Stereolithographic resins

Materials and Applications

Stereolithographic liquid resins

Stereolithography prototypes

Rigid resins, both transparent and opaque, characterized by a high construction detail, rigidity and refinement to obtain remarkable aesthetic impacts. They are perfect to use to create aesthetic demo objects that have no major mechanical stress. As a small counter we point out that high rigidity can lead to fractures in the event of overstressing.

The material is processed by an ultraviolet laser that reinforces it and constitutes the object. Specifically, stereolithography has a very refined tickness layer that allows the construction of highly detailed models. It can build rigid details, both opaque and transparent, and with an important mechanical characteristic (especially if ceramic-enriched material is used).

Features

Stereolithographic resins

Stereolithographic resins are materials designed to reproduce really high details, which is why they are characterized by a high structural rigidity that translates into a certain fragility, especially in reference to minute structures. They are usually transparent or translucent (even if there are opaque resins or with ceramic caroca). This detail makes them perfect for reproducing prototypes for inspection, window compartments and other lenticular objects. It is good to keep in mind that the stratification present on the surfaces due to digital printing can partially alter transparency (transparency will be excellent if the faces of the object are flat, not particularly sculpted, or even better if they can be polished. In the case of technical surfaces “Sculpted transparency will be more indicative allowing you to recognize shapes or colors but not the details). The material has a glassy resin consistency, easy to finish, with very smooth surfaces.

  • High dimensional compliance which makes it the most suitable technique for making templates and calibers in general
  • The working range is 400x400x400mm (larger objects can be made by enclosing rigid modules)
  • The Layer Thickness is 25 microns
  • The opaque materials are ivory, while the transparent ones require polishing to have a lenticular appearance
