The Composite-X resin from the catalog of engineering resins by Liqcreate is an extremely rigid and high performance nano-micro composite reinforced resin for SLA, DLP and LCD/MSLA 3D printing. With a flexural modulus of around 9000 MPa and a flexural strength of up to 170 MPa (with thermal post-curing), the Composite-X resin is superior to almost all photopolymer resins currently available on the market.
Apart from the high rigidity, the Composite-X resin is characterized by high strength and great chemical resistance, as well as extremely low shrinkage and odor during printing. All these properties make the Composite-X resin the perfect material not only for rapid tooling but also for heavy duty industrial or automotive applications, wind tunnel testing, fluid flow components, etc.
The Composite-X is easy to use on all open SLA, DLP and compatible LCD/MSLA 3D-printers in the range of 385-420 nm by brands such as Anycubic, Phrozen or Creality. A full list of compatible printers can be consulted on the manufacturer's website.
It should be kept in mind that the Composite-X resin is intended for advanced users. Furthermore, the Composite-X resin can have an abrasive effect on aluminum parts due to the ceramic particles it contains. This is why it is highly recommended to use anodized aluminum or coated aluminum resin tanks when working with the Composite-X resin. More advice on printing with the Composite-X resin can be found in this article on the manufacturer's website.

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