eSUN eResin Water Washable - Grey 0.5 Litre

As our hobbyist toys get better and better by the year, we’ve been having some serious fun in the world of 3D Printing, which is branching out quite nicely to cater to many different styles of Making, creativity and science. That’s why, even though DLP Printers are not necessarily new, we get really excited when we find cool new polymers to play, experiment, and print marvellous creations with, and this eSUN Water Washable eResin is one such polymer that we’re particularly excited with. And although this polymer doesn’t necessarily add any unique mechanical properties, such as eSUN Flexible eResin or eSUN Tough eResin, it does bring a distinct advantage to the playing field, and that’s the fact that it is cleverly polymerised to be washable with water, rather than harsh chemicals like IPA or Resinaway.

Although it’s quite hard to argue against the fact that working with 3D Resins is a messy task, often resulting in blobs and layers of hardened resin randomly strewn about on the working space once post-processing is done. This is what makes eSUN’s specialised Water-Washable Resin so much more enjoyable to use than many of the alternatives on the market, as instead of having to prepare some IPA, Resinaway or similar cleaning agents and carefully handle them so they don’t cause their own problems, you can simply wash your prints in water once they’re done, making the entire 3D Printing process so much easier, less messy, and overall more efficient too. Furthermore, this specialised polymerisation also inadvertently makes resin printing less odorous both during printing and cleaning, and of course means that once you’re done post-processing your prints, they aren’t going to have that slight smell of alcohol or other harsh chemicals like typical prints can.

When choosing between colours for DLP Printing, many people initially consider getting some fun colourful Photopolymers that really stand out with vibrant hues and shades. However, users who like to post-process prints by painting them or otherwise giving them a fresh new layer of extra colour on top will understand that Grey is typically the best choice to use, since grey can act as the perfect primer to ensure that whatever other colours you use really stand out once applied. Furthermore, grey does an excellent job at highlighting various features, corners and planes, and this makes it more enjoyable to post-process, as it’s rather easy to imagine various colours being applied to each distinct detail of the print, while the neutral colour also means that you won’t have the ever-common problem of colour bleed-through from the underlying material. So if you love post-processing and painting all of your DLP Prints, or if you simply love the sombre and sleek style that grey offers for prints, then there is simply no other colour that can compare.
