Lychee Slicer new Major Release : Filament and Resin!


You’ve waited for it, and here is the big reveal! Here is our new major version of Lychee Slicer, internally numbered 5.0. We have major additions, introduced a month ago through multiple public betas, that now come as stable… but we added the support of filament 3D printers as a public beta! And that’s a big change!

But Lychee Slicer remains the same: one application, but for two types of 3D printers, still in Free and Pro, with a Premium option. However, Pro is now specific to each type of 3D printer.

Below are all our latest additions for the resin features, but let’s talk about the 3D filament printers.

If you created your own Filament 3D Printer, or if you purchased one that is not yet listed in Lychee Slicer, you will now be able to add it in just a few easy steps! Then, it will be ready to print with Lychee Slicer!

Batch Tool in Lychee Slicer

Batch tool for Filament 3D Printers

[Filament – Pro and Premium]

If you are managing several models at the same time, you can now use the Batch Tool feature. Using this tool you can complete common tasks with your 3D models in just a few clicks, including: add suffixes, repair objects, rotation, support, island analysis… and much more!

Speed improvement

Improvements in Performance and Speed

[Resin and Filament – Free, Pro and Premium]

We worked on some fluidity and speed improvements for some aspects of Lychee Slicer. Now, the “Arrange All” tool is more than 40% faster!

The file loading is faster, support placing is smoother, and many other aspects of Lychee Slicer are now also improved. This is an on-going process, and we will continue to work on these aspects for every future release.

Translation in Lychee Slicer


[Resin and Filament – Free, Pro and Premium]

We added a new translation for our Chinese friends: Traditional Chinese! Simplified Chinese has also been massively improved! Thanks to Sam for his massive translation work! 

Also included in this release, it will now be possible to have a multilanguage version for the Filament part of the slicer.

Filament parameters

Filament Parameters Improvements

[Filament – Free, Pro and Premium]

It is now possible to edit new parameters in the filament settings: nozzle size, filament diameter.

We also added the ability to add custom GCode on changing layers, perfect for time lapse creation.
