The Liqcreate portfolio of engineering resins contains many materials for applications that require specific mechanical properties. One such engineering resin is the heavy duty Tough-X resin, a durable opaque black resin that stands out due to its high impact resistance and an elongation of up to 150 %.
An interesting feature of the Tough-X resin is that thin designs 3D-printed with it resemble rigid rubber and thicker parts feel robust like ABS plastic. This makes the Tough-X resin ideal for the manufacturing of industrial spare parts for demanding mechanical applications.
Just like all Liqcreate resins, the Tough-X resin can be used on most open material resin 3D printers available on the market, for example printers by brands such as Phrozen, Uniz, Creality or Anycubic. This is due to the resin's wide range of compatible light sources (385-405 nm). The manufacturer provides a full list of compatible 3D printers as well as the recommended printing settings.

In order to ensure resin longevity and successful 3D prints, it is advised to store the Tough-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 Tough-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.
