Reactivity to light is measured by exposing the resins with different doses of energy (Exposure), in most cases this is controlled by increasing the exposure time in the 3D-printer. These two values are empirically derived values based on measurements using a 3D-printer. Specific parameters about its reactivity are the Critical Enegergy (Ec) and the Depth of Penetration (Dp), two values which can be found for all Liqcreate materials in their corresponding Technical Data Sheet. This reactivity controls how the resins behaves in the printer. What are Ec and Dp values?Īll Liqcreate resins are UV-curable 3D-Printing resins, which means that they have a specified reactivity to light. In case of resins, the physical state should always be liquid. The appearance will give more information about the color and the physical state of the material. The first part of the technical data of a material will tell more about the liquid properties. The table below will show the technical data of Liqcreate Strong-X: To explain the meaning of mechanical properties, the example of the technical data (from the TDS) of Liqcreate Strong-X is discussed. What do these mechanical properties mean and how do they relate to your application? This article will give an inside in the meaning of mechanical properties and answers questing regarding these properties. In many cases a 3D-printing resin suppliers provides a set of mechanical properties for each material. Mechanical properties can help you choose the right resin for your application. Because of the difference in chemical composition of the resin, the mechanical properties (material characteristics) are very important and will help to compare different resins. In contrast to FDM, where polymer filament is used from a known material with certain mechanical properties, SLA, DLP and LCD 3D printers use resins where mechanical properties are obtained by the chemical composition of the resin. There are a lot of resins materials available on the market, all with different mechanical properties and prices.
