Lychee Slicer Changelog

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

Major Release: Lychee Slicer 3.5/3.5.1

Release date: 2021-07-27

With this major version of Lychee Slicer, you will see multiple changes in the interface et workflow.

The “Support” section was renamed Prepare as it was never really just for supports. “Prepare” contains all of the support, raft, and hollow tools with more features coming soon!

You’ll notice that the “Prepare” section now has dedicated buttons for each tool on the left. Clicking on Support, Raft, or Hollow buttons will open a dedicated panel with the functions and settings. Each of these now opens on the right side of the display to match the historic location of the Support settings.

An important note, pressing the Shift key while clicking on a tab will open it without closing any other tabs. The UI state will be saved when quitting Lychee Slicer so picking up where you left off is easy.

The “Preview” section has been merged with the “Export” section at the top of your display.

Netfabb Online was discontinued and we’ve replaced it with Microsoft Azure as our integrated online repair tool. We’re developing our own tool to repair models, and we hope to have it ready soon!

In addition to this interface and workflow change, we did multiple additions and changes and as usual, added multiple 3D printers and the “mods” that turn an RGB 3D printer into a mono screen one.

Global

  • Updated interface and Workflow: renamed “Support” section to “Prepare”, “Preview” section merged in “Export”, Support, Raft and Hollow tools with separate setting panels.
  • Microsoft Azure is now replacing Netfabb Online: Netfabb (Autodesk) has been discontinued. You need a Microsoft account to use this service. The workflow remains the same.
  • New View Modes & Menu added: Accessed under the View Cube found top right of the display, you can toggle new viewing modes. View the Normals (:rainbow: very pretty!) and/or Wireframe of objects in the scene and you can toggle Flip Camera and Orthographic view options from this menu.
  • 3D model lighting has been enhanced with Matcap: The scene is now lit with integrated Matcap, giving an even more detailed and accurate view for the 3d objects.
  • 3MF file support added: You can now import 3MF files directly into Lychee Slicer.
  • The Object list can now be sorted by import order as well as by name.
  • Added a shortcut to reset the clipping bar to the home position (‘Home’ key)

 Supports / Prepare

  • Global Detection Collision [Pro] : A new tool that will analyze the model (or scene) and display all supports that collide with other objects.
  • Collision Detection in Real-Time [Pro] : Now when manipulating your supports, they will turn red if they collide with a 3D model or are too close to an object (risking merging during printing). If you switch to Advanced Support Mode, it will display which of the segments collide.
  • Advanced mode for Drain Holes [Pro] : Similar to Advanced support editing, with drain holes selected press Spacebar to activate Advanced editing mode. You get a 3D gizmo on screen to manipulate the holes (move, scale, and rotate).
    Note: the holes are displayed in partial transparency to view their depth.
  • Adaptive Support Bases [Pro] : When enabled, support bases will automatically conform with the shape of the 3D model without touching or overlapping it. If you print your model directly on the platform, support bases will not clip underneath the model.
  • Improved Island detection
  • Visual representation of islands has been improved.
  • Improved the “search to ground” function for supports.

Various fixes and optimizations

  • If resin compensation is not applied to supports, then it is no longer applied to the raft.
  • Several random crashes.
  • Fix CWS Export Png Format.
  • Multiple fixes and improvements.

Major Release: Lychee Slicer 3.4

Release date: 2021-06-14

This version of Lychee Slicer brings new additions like the long-awaited resin compensation* [PRO], new improvements in the anti aliasing function with better spreading of the grayscale pixels, and now manual and auto supports are avoiding drain holes.

A lot of changes have been made under the hood, and countless hours of work that are not always visible to the end user, but these changes to the software will make our future feature implementations easier. A new public beta version with a whole range of new interesting features will be available soon after this version.

As usual, we fixed multiple bugs, did some (well, a lot!) optimizations, and added support for as many new 3D printers as possible. We also did a major upgrade in the framework we are using which improves the compatibility of Lychee Slicer with some computers that have WebGL issues.

Thank you for reading the version 3.4 changelog. Below you will find the most complete list of details.

*About the resin compensation: This function reduces the effects of expansion or contraction produced by the resin during the printing process. It counteracts the well-known “Elephant’s Foot” effect.

Some printers like the Anycubic Photon Mono X, automatically add transition layers. We have added a field in the printer settings to indicate the number of layers to be taken into account if the compensation exists for a given printer. For example, the user will enter the value 10 for the Mono X.

Note: be careful to increase the support tip penetration value to avoid having a support that is not connected to the 3D model when using a negative compensation!

Global

  • Various performance improvements in the application: 3D view, slicing speed, memory usage, duplication of models with supports, multiple deletions of models at once, and more.
  • A mini Theme Editor has been added in the preferences menu, to let you change some colors (overhang checker, island detector)
  • Delete all the variable layers at once by pressing the Shift key while clicking on the trash icon.
  • Camera navigation has been added to the shortcut editor.
  • The Arrange All tool is now available in the bottom bar even if no object is selected.

Resin and 3D Printer settings

  • [PRO] Resin compensation added for overexposed layers (elephant foot effect) and regular layers.
  • Horizontal scaling factor for the plate, some users prefer this solution over the compensation function.
  • Transition layer count entry field for 3D printers that automatically add transition layers like Anycubic 3D printers, are taken into account by the resin compensation. Setting is located in the 3D printer settings (not in the resin settings).

Supports

  • Improved speed when dragging supports.
  • Quick select of all the mini supports, added in the Support menu. It will be easier to do mass editing to mini supports to add or remove a few fractions of millimeters with the help of the calculator (Calculator is Pro only)!
  • Support Error sphere: it displays a tiny globe and not the cone type shape when you try to add a support on a location that prevents you from adding this support. To enable, turn on the Preferences >> Support Menu >> “Ball shape for real-time supports in error” preference.
  • Manual and auto-supports now avoid drain holes.
  • The minimum tip size limitation has been removed.
  • Bracing on tips have been removed to avoid 3D model intersection.
  • Improved island detection and accuracy, especially in Real mode.
  • Users of the free version can remove the 3D hollowing that was created in the free version.
  • Numerous improvements on recalculation of support bracing and parenting, typically after rescaling the model.
  • New “Shift supports to new object center” function located in the Layout >> Object menu. This will correct supports that shifted when reimporting a model if needed.

Export / Slicing

  • Antialiasing V1 has been removed. V2 becomes the default.
  • Important reductions in memory consumption during slicing (approximately 75%).
  • If you have models with topology issues, artifacts should not go to the bottom nor to the top of your 3D print volume during slicing. Of course to avoid them entirely, fix your 3D models first. No red/warning sign is the key!

Interface

  • Improved organization for recent files/imports.
  • The Object List has been improved. You can click-drag the visibility across the objects (like Photoshop). You can also hold Shift or CTRL to select multiple objects at once or totoggle the selection.
  • The Object list can now be resized horizontally, useful when you have long file names.
  • The Object list tool-tip now displays the full name on mouse-over. It was problematic before, with very long file names.
  • You can use the Shift + Up/Down keys to go 5 by 5 layers with the clipping bar.
  • You can now click in the clipping bar widget to enter a layer number and then jump the clipping bar to this layer.
  • Clipping bar orientation (top view or bottom view) shortcut has been added to the shortcut editor.
  • Clipping bar top value is updated when objects are set to hide/visible.

 3D Printers

  • Uniz IBEE
  • Qidi Tech i-box
  • Peopoly Phenom XXL
  • Epax E10 5K
  • Tianfour H400
  • Sparkmaker FHD fixes (Gcode and plate values)
  • Various corrections in the file format of the Longer 3D printers

Major Release: Lychee Slicer 3.3.1

Release date: 2021-03-05, updated 2021-03-09

This version of Lychee Slicer is a major version, providing new features, but numerous improvements and changes under the hood that will speed up the application. The changelog below lists all the additions, changes, and improvements since version 3.2.1.

Please read it carefully as it provides important information.

Added – Global to the application

  • Memory management improvements. It should help a lot in complex scenes with high-resolution 3D models and a lot of supports.
  • Performance and memory-wise, the support engine has been drastically improved. It may not be obvious feature-wise, but it improves performances and reduces lags. You should see an improvement when working with build plates full of models and supports.
  • There are multiple improvements in speed and performance, like slice speed with scenes with large amounts of supports, raft creation/update 75% faster, scene manipulation in the Layout section, 3d models auto-arrange, undo/redos, and more. You will love to arrange your plates full of 3D models!
  • New 3D Printing History. It keeps track of your history of exported slices and lets you rate your prints. Then add comments, edit the real printing time, and more. You can export (and share) the resin settings you used for your successful print from your History. History can be disabled in Preferences.
  • You can now import resin settings from some slice files: just load a slice and a resin profile, using the slice parameters will be created. It works with most slice file formats: CTB, PW0, PWS, PWMX, PWMOSE, PHZ, CBDDLP, etc.
  • [PRO] We added a new Shortcut editor in preference. You can edit only the existing shortcuts (sorry!). It supports regular hotkeys (one letter or combine d with a modifier key like ALT, but you can also do a sequence of keys, like ALT+R, E.
  • New resin volume calculation tool: gives an estimation of the volume at any time. The estimation will be a little bit less accurate than the one performed during the exported slice.
  • New setting in resin: Time per Layer. Set the time it takes for your printer to print a single layer and enter it. The total printing time will become more accurate!
  • We updated the antialiasing with a new grey level offset feature. We did some other changes to the AA and fix some issues with some Anycubic printers.
    Note: we had some reports of problems of AA with recent Anycubic printers. Please update your firmware, most of them are not related to Lychee Slicer.
  • Improved model replacement position. In previous versions, replacing a 3D model in the Layout section was moving it if the bounding box was changed. Now, the model position remains in place, and supports are eventually recalculated. The Move Tool has an option to read and use the world position saved in the 3D file, letting you verify if two objects share the same position.
  • We added a link to external tools. You can send an STL straight to Netfabb application if you installed it on your computer or send your slice to UVTools. You can even run command-line applications at the end of the slice.
  • [PRO] 3D printers Z axis size is now editable
  • Printable XY size for the 3D printer has been added to the 3D printer settings. It lets you see the difference between the build volume and screen size, which can be different on some 3D printers.

Added – Scene management

  • To help you manipulate your models on the build plate, we added a new Arrange tool. It lets you do only operations to translate and rotate your models without the risk of changing your supports.
  • We changed the Object List. It’s now a part of the toolbox on the left, and you can leave it open. For each model, you can find stats by clicking on the small triangle on the left. This menu will become more and more powerful over time.
  • We revert some tools organization in the Layout section (rotation/move).

Added – Supports

  • A new quick mode has been added to the manual support creation to create new supports using the same starting point and parameters as the previous one, which is ALT+Shift hotkey. Let’s say you make mini support (ALT+CTRL), then when done, just press and hold ALT+Shift, then click on your model to create the same mini supports, starting from the same starting point. It works with manual bracing, manual parenting.
  • [PRO] Allow free-floating support using CTRL key in Support Advanced mode. Keep the CTRL key pressed in Advanced mode while dragging the arrow key to disconnect the tip and/or the base from the object/floor, allowing you to create floating pillars for advanced (and some madness) support holders/pillars.
  • Support individual slider settings in multiselection: affects only the values of the current slider and not apply all the other parameters to the selection of supports.
  • [PRO] Relative supports calculator. Add relative values to your selection of supports: add +0.2 mm to all selected support tips at once!
  • [PRO] You can import/export Support presets (in the “Custom” dropdown). Please keep in mind that it will export the presets that you have “by default”. Please overwrite your presets to be sure they are saved in the software before exporting them (no “star” next to the presets).
  • [PRO] Raft user preset. Save your raft settings and use them again later.
  • [PRO] Hollowing user preset. Save also all your hollowing parameters as presets.
  • Auto Support can now be generated only from the build plate and not from the model, and only for the hollowed parts.
  • [PRO] New support cylinder shape type
  • [PRO] Support base cube can be set at a 45° angle.
  • A new action, “Make Support Pilar“, in the support right-click menu (ALT+P) will turn the selected support(s) to straight support from top to bottom.
  • A new option to select only the supports’ bracing has been added in Supports > Select Bracing Support menu.
  • A new shortcut, Shift+V, lets you switch between the current support visibility type and the previous one. For example, switching between All and Contact point and vice-versa.
  • Improved island detection for tiny/thin shape, like spikes.

3D Printers

  • Phrozen Sonic XL 4k (Export rewritten, consider it as a new printer!)
  • Creality LD 006 – Support Variable Layer height, Transition Layers
  • Elegoo Mars 2 – Support Variable Layer height, Transition Layers
  • Elegoo Mars new mod 250 mm (For DIY Z height modifications)
  • Fix Elegoo Mars Pro maximum Z axis at 150mm
  • Voxelab Proxima – Support Variable Layer height
  • Phrozen Mighty – Support Variable Layer height, Transition Layers

Changes (just a few of them…)

  • We updated the visual feedback when importing, overriding, and resetting the support presets.
  • Multiple selected objects are now manipulated as a single group when rotating, translating, and scaling them. The Gizmo location is now centered on the object multiselection. The action will be performed to all the objects as a single one, not individually like it was before.
  • The bracing of two very close supports together is now possible. Select first the supports, then brace them. It works only for two supports
  • When exporting a slice, the default filename will be the LYS/LYT scene file’s name.
  • The default folder for saving the scene file is now the STL folder location.
  • Support can now be placed on support tips.
  • The Lift function can now be set to 0 (and not 1) mm for its minimum value.
  • Various changes to improve the visibility of islands when searching for them.
  • [PRO] Hollowing 3D wall thickness value can be set to 0.5 and not anymore 1mm.
  • Lychee Slicer remains in the export Menu after a slicing.
  • Gizmo misplaced onto the object within the arrival animation
  • Base Join visibility in Advanced Editing Mode
  • Raft base support override
  • Clipping bar doing only on/off
  • Warning message for files bigger than 200 Mb updated to 500Mb. This message was not an error, just a warning. Most of the time, loading large STL files is overkill as 3D printers resolution is (way) lower than 3D model one.
  • Clarification in the EULA for the commercial/non-commercial usage of the application. Both Lychee Slicer Free and Pro license allow you to use the application for commercial usages.
  • Auto-calculate print time in preference reset to false for all the users because of the new computation mode.

Fixes and optimizations

  • Phrozen wifi printing status
  • Default Name Export Resin
  • Ask the user to select an STL if data is not found in the scene file
  • Linux App Icon
  • White 3D View after a screen-saver

  • No more cathedral support for inside support
  • Layer range colors have been improved
  • Delete a duplicated object delete every hole
  • Support error in 3D hollowing
  • Fixed the tip topology issue when using recalculating supports when in “only contact” visibility mode
  • For some users with multiple 3D printers and resin profiles, the 3D Printer and Resin manager had slow down and refresh issues. It has been fixed and optimized.
  • Parenting two supports will not delete all the bracing anymore
  • Improved undo/redo with multiple objects
  • Improved loading processes
  • Improved readability in the Recent files/import (no more long path)
  • Fixed a visibility issue with support lines with hidden objects
  • Fixed some file name issues over Wifi
  • Open/Save buttons fixed on Linux
  • Improved island detection for tiny/thin shape like spikes
  • Supports inside the hollowed part of the model were not correctly flagged. If you want to fix your existing model supports affected by the issue, click on “Add/Update” button of the 3D hollowing function. It will rebuild the hollowing and will fix the support flags.
  • Some issues related to the loading of LYT/LYS files included the same STL have been fixed.
  • Open file with a double click on Windows issue fixes
  • We fixed a memory leak during the slicing process for Nova 3D printers has been fixed.
  • Now, the Move / Arrange gizmo has some transparency on mouseover. Before, it was 100% opaque, preventing good visibility when models were below.
  • Rafts are now hidden when the visibility Inside mode is active.
  • 3D mouse support improvement.
  • Some issues with Wanhao D8 Workshop.

Lychee Slicer 3.2.2/3 – Public Beta – 2020-12-15

This version of Lychee Slicer is provided as a public beta as it brings new features that may impact your way of working and, more importantly, are working on core functions. They have been tested, but we advise our users not to use them in production.

We introduced the local editing of support parameters when having a multiselection: changing one slider value will affect only this value for all the supports. Before, it was replacing all the values from the selected support.

Besides, we added a little calculator in the Pro version, which lets you add, as an example, +0.1 mm for all your support tips of a multiselection. All the tips values will be increased by +0.1, whatever their original value.

Finally, we introduced a preset for the raft. Save your current settings and recall them later.

Added

  • Support individual slider settings in multiselection: affects only the values of the current slider.
  • [Pro] Relative supports calculator. Add relative values to your selection of supports.
  • [Pro] Raft user preset. Save your raft settings and use it again later.
  • Improved model replacement position. In previous versions, replacing a 3D model in the Layout section was moving it if the bounding box was changed. Now, the model position remains in place, and supports are eventually recalculated.
  • Printable XY size for the 3D printer has been added to the 3D printer settings. It lets you see the difference between the build volume and screen size, which can be different on some 3D printers.
  • Purchasing the Pro subscription can be done from within the application or can be done by opening our online store. Some users were not confident in buying from the application. Now it’s possible to decide what to do.
  • An email provider check has been added. Some providers don’t like our emails, and they n

Fixed

  • Loading issue with LYS files (3.2.2)
