The Liqcreate team of experts on photopolymers and 3D printing ensures that the Liqcreate resins can support the most demanding applications, and this is the case of the Premium Tough resin - a tough and impact/scratch resistant photopolymer for LCD and DLP 3D printers.

Just like all Liqcreate resins, the Premium Tough resin can be used on most open material resin 3D printers available on the market, for example printers by brands such as Phrozen, 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.

The Liqcreate Premium Tough resin has a transparent color that turns milky white during polymerization. The key features of this resin are its high impact strength and exceptional scratch resistance, which produces parts that are durable, tough and resistant to abrasion due to prolonged use. The Premium Tough resin is perfect for manufacturing functional prototypes that require those properties.

As far as the post-processing of the Premium Tough 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.

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