The Liqcreate portfolio of engineering resins counts with the Strong-X resin, a material characterized by high strength and stiffness, as well as great resistance to high temperatures. Strong-X is an easy to print opaque grey resin with low odor during printing and low shrinkage of the parts.

These features make the Strong-X resin perfect for heavy duty industrial applications (injection molding), or in the electronic or aerospace industry. The flexural strength of the Strong-X resin (135 MPa) is similar to that of some of the leading indystrial cyanate ester resins.

The Strong-X resin can be used on many open source 3D printers by brands such as Uniz, Formlabs, Zortrax, Anycubic, Creality or Phrozen thanks to the wide range of compatible light sources (385-420 nm). The full list of compatible printers is available here.

In order to ensure resin longevity and successful 3D prints, it is advised to store the Strong-X resin in a clean and dry environment, out of direct sunlight and in a temperature of 5-30 ºC. Before use, the resin bottle should be shaken energetically for at least 1 minute (at least 3 minutes in the case of filled resins) and then left to rest for around 10 minutes to let the air bubble escape. Leftover resin can be poured back into the bottle but it should be first filtered to ensure there is no polymer residue present. Safety equipment such as protective garments, gloves and face protection is highly recommended for the handling of resin.

As far as the post-processing of the Strong-X resin, a few simple steps must be followed. First, the 3D printed part has to be cleaned for a maximum of 6 minutes in Liqcreate Resin Cleaner, IPA alcohol or bioethanol, preferably ultrasonic or under agitation. Then the completely dried part has to be cured in a high-power UV curing chamber. The curing workflow is explained in detail by the manufacturer here. It absolutely crucial that the parts are dry before they are cured. The curing of wet or sticky parts will lead to mechanical and surface defects. The drying can be done by simply leaving the cleaned part in a well ventilated area for at least 30 minutes or with the help of pressurized air (2 minutes) for parts cleaned in IPA alcohol or ethanol.
