General purpose resin for prints with a great surface finish and accurate details.

Liqcreate, the Dutch designer and manufacturer of premium photopolymers for DLP, SLA and MSLA technologies, has a rich catalog of resins for general applications as well as premium, creative, engineering, dental and castable resins. One of the Liqcreate general purpose resins is the Stone Coal Black resin.

It is an opaque high resolution photopolymer resin characterized by a very smooth surface finish of 3D printed parts and great accuracy with small details.

Just like all Liqcreate resins, the Stone Coal Black resin is compatible with most open material resin 3D printers on the market due to the resin's wide range of compatible light sources (385-405 nm). Thus, the Stone Coal Black resin can be used with XYZ, Uniz, Phrozen, Creality, Anycubic or Formlabs 3D printers, and more. The manufacturer provides a full list of compatible 3D printers as well as the recommended printing settings.

These features make the Stone Coal Black resin ideal for applications such as rapid prototyping and product development in many industries as it creates detailed, accurate and beautiful black objects. When 3D printed, the Stone Coal Black resin produces very low amounts of odor, which makes it user-friendly and adequate for use in any workspace.

The post-processing workflow for the Stone Coal Black resin is quite user-friendly. 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.

The Liqcreate resin bottles should be stored 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). Once shaken, the resin should be 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.
