Lychee Slicer Changelog

All notable changes to the Lychee Slicer development are listed below. Some minor changes and additions maybe not be on this list. Internal versions may not be included.

This is a long list because we like adding a lot of features and improvements. Pick some popcorn first, you have a lot to read!

Lychee Slicer 5.0 – Major Release with Filament printer addition

Release date: 2022-11-23

This new major version adds support to filament 3D printers and includes several major features for both Filament and Resin 3D printers.

Reminder: Resin slicer is stable, and Filament slicer is a Public beta.

New features

  • Filament slicer added: It’s not only a new feature, it’s a whole new slicer, for your filament 3D printers.
  • [Pro Resin & Filament] Planar Cut tool, to cut 3D models in multiple parts, including selecting the cut-outs.
  • [Pro Resin & Filament] Inline Support creation tool. Add multiple supports aligned along a line in two clicks.
  • [Pro Resin & Filament] Split and Merge tools: Separate the 3D model shells into multiple 3D objects or merge a multiselection of objects into a single mesh.
  • [Pro Resin] Suction Cup detector: Detects if your print has suction cups that could lead to a print failure. Then, after adding holes to avoid this effect, you can reanalyze your model to ensure there won’t be any suction cups.
  • [Pro Resin] Support Presets: create and save your own support presets. No need to create them every time!
  • [Pro Resin] Support Painting with max angle: define angles to ensure you don’t draw the sides or border of your model. This is helpful for bases or preventing you from crossing a border.
  • [Pro / Premium / Free Resin] Anti-Aliasing has been enhanced and provides better results along the XY plane. Also it improves the Blur antialiasing option, which can be a good option for clean surfaces on models that don’t have tiny details. Name has been updated, Blur is now “Smooth Surfaces” and is the one by default. The former anti-aliasing has been renamed to “Sharpen Details”.

Improvements

  • [Resin/Filament] Auto Arrange tool now better considers the model’s shape and is more effective. Magic features take advantage of this feature.
  • [Resin/Filament] The mirror tool is now in the World orientation and not anymore in the local one.
  • [Resin/Filament] We speed up a lot of tools and processes, like the application startup, scene loading, auto arrange, supports bracing, and even the copy tool that had been sped up quite a lot in the previous update.
  • [Resin] A lot of cleaning has been done in the Community Resin tool. We still have some cleaning to do, but we are in the process of providing you with a great tool to help you find the best parameters for your 3D printer and resin combo.
  • [Resin] CTB-based 3D printers using the V4 format can change the LED power in the resin settings.

New Resin 3D printers and profile improvements

  • Anycubic Photon D2
  • Anycubic M3 Premium
  • Anycubic X2
  • Elegoo Saturn 8K

 Bug fixes

We have addressed many bugs and issues, too many to list however, here is a list of the most important ones.

  • 3D printing time estimation with printers using two stages movements (CTB V4 and recent Anycubic printers)
  • Resin estimation included support resin consumption even if the scene didn’t have supports. This has been fixed.
  • Supports ignored drain holes when located inside of a hollowed model.
  • Visual artifacts and slicing issues when having too many supports (and bracing) on top of each other.
  • Various minor bug fixes.

Lychee Slicer 4.1 Stable (and 4.0.12)

Release date: 2022-8-25 and 2022-8-30

This version concludes our last round of beta version and is now considered as a stable version.

New feature

  • Isolate your object: Use CTRL+ left CLICK on the eye of the object list to isolate your object and hide the other objects on your plate! There are also shortcuts in the top menu and right click to manage the isolation.

Improvements

  • Object Duplication is now way faster than before! Easily and quickly duplicate your objects without any more long waiting time.

Bug fixes

  • We tracked down some bugs to fix them!

 

Lychee Slicer 4.0.10 – 4.0.11

Release date: 2022-7-19

This minor beta update fixes only issues found in the previous beta:

Bug fixes

  • Flip of slice that could happen sometimes for a single layer
  • A major issue found while using the hollowing blockers with non uniform scaling meshes (sometimes, even using the Uniform scaling would introduce a slight variation of 0.001%, enough to trigger the problem)
  • Some issues with the detection of the inside of the mesh when painting supports outside (or the opposite)
  • Unable to choose “mm” for some X, Y Z fields
  • Some issues when trying to put some supports and that could make the normal line crashing/freezing
  • Other various bug fixes.

Additions/changes:

  • We reduced the Support Painting minimum interval value to 0.5mm
  • New settings to avoid every supports or only support added during the current stroke in the paint support

 

Lychee Slicer 4.0.7 – 4.0.9

Release date: 2022-07-12

This minor beta update fixes only issues found in the previous beta:

  • The selection rectangle issue has been fixed
  • A problem where the 3D hollowing was not visible has been fixed
  • A problem affecting the parenting tool has been fixed
  • A build plate opacity issue has been fixed as well
  • The reset of the 3D view with the middle button click has been fixed (double click)
  • Some users non-visible bugs fixed

 

Lychee Slicer 4.0.6

Release date: 2022-06-29

This major update introduces a new interface with a new design and colors. Almost all the existing features are at the same location and behave similarly. The transition should be transparent for all our users. However, many modifications have been made internally to prepare for our future (ultra major!) developments.

 

New features

  • [Pro / Premium] Physical Size mode: display your 3D model at their real word size. The function is located in the Simulator and At Scale functions, found in the Export workspace.
  • [Pro / Premium] Support Painting mode: paint your supports on your model and eventually, with the help of your pen tablet pressure.
  • [Pro / Premium] Batch Tool now supports the Object notes: add custom notes to all the objects you process, great for content creators who need to add read me or copyright information. Premium users can also add images to notes.
  • [Pro / Premium] Saved Views: save the camera point of view and recall it later. Save up to 4 different views.
  • Layers Thickness Preview: This function, found in the View Cube options (Gear icon) displays all the layers on the 3D models. It helps you understand better what your 3D printer will print.
  • Oh! We have a new logo!

 

Improvements

  • New interface for the Support manager, with a visual indicator of what each slider does.
  • Clipping bar widget (simplification)
  • Community Resin sorting has been improved to consider better the popularity of resins, especially when they are certified by a Brand or an Influencer.
  • The management of creating a new resin profile from scratch has been improved: you must first select the existing brands, types, and colors in the list. You must select Other and type your custom name if they do not exist. The purpose is to avoid duplicated names for the Community profiles.
  • Open the Lychee Slicer data folder from the Help menu. useful when you need to do a clean reinstall of the application.
  • Tab hotkey to swap between the different workspaces (Layout, Prepare, Export) has been disabled. It was interfering too much with the text/input fields.

 

New 3D printers

  • Elegoo Saturn 2
  • Elegoo Mars 3 Pro
  • Phrozen Mighty 8K (updated)

Note: Peopoly Forge and Nova 3D Bene 6 will be added very soon in a point update.

 

Bug fixes

  • 3D hollowing is now working when using the Mirror tool.
  • CTB V4 export can now be canceled without an application crash
  • The clipping bar was never at layer 1.
  • CFG import is now working with the TSMC mode (CTB-based printers).
  • Community Profile URLs are now working.
  • The clipping bar was not updated after an undo or using the Lift function
  • The wireframe was not displayed as expected when using the Hollowing Blockers
  • A billion (at least!) of minor bug fixes
