What’s New

Lychee Slicer – What’s New

Lychee Slicer 3 is an easy to use slicer software with a user-friendly interface. It helps you prepare your 3D models for resin 3D printing in an efficient way, and will assist you in the preparation of even the most complex 3D models.

With version 3, much of the foundational software engine has been rewritten, including the automatic and manual support engine. And now, it’s FREE!

Lychee Slicer is now available in two flavors:

Lychee Slicer – Free

This powerful and full featured application will allow you to prepare your 3D models for resin printing, including automatic and manual support placement and a huge list of high-quality functions and tools.

The Lychee Slicer Free version is supported by just one unobtrusive advertisement page rather than a banner or permanent scroll. The free version displays only 3D printing-related advertising from our partners, and only on one screen before slicing and exporting a file.

Lychee Slicer Pro

The Pro version adds industry leading, advanced features that will greatly benefit experienced users and serious hobbyists. Pro users enjoy increased functionality in manual support adjustment, 3d hollowing, and many other powerful features. The best tool for file preparation available, Pro is also fully ad free.

The Pro version can be tested at no cost for 30 days. Simply download the Free version and activate the 30 day trial period. Please note, the free trial of Pro still displays an ad before slicing, but the ad may be skipped.

Lychee Slicer 3 is available for Windows, Mac OS, and Linux

New 3D printers support

We are on the cutting edge of new 3D printing hardware!

Lychee Slicer never stops adding support for new 3D printers, with many new models added before they are even publicly available for purchase! Elegoo, Anycubic, Phrozen, Creality, Epax, and all the major brands have supported profiles in Lychee. Our slicer also supports all the less common printer brands, and we will continue our ongoing development of modded printer support.

Automatic support algorithms

Lychee Slicer 3 provides an evolving and powerful automatic support system, which includes optional bracing and parenting functions. For each support created, our algorithm avoids the model as much as possible as the supports seek out the ground. The process is highly customizable and users can tune their settings to achieve consistently successful prints without over-supporting their model. This tuning allows fewer support artifacts, far less cleanup in post processing, and a higher quality product overall.

No one likes sanding support tips or filling tiny pockmarks. Our supports are uniquely engineered to allow for a shallow penetration depth, leaving as little resin behind as possible once removed.

Of course at any time, all of your supports can be manually edited for fine-tuning the perfect print.

Manual Supports

Lychee Slicer is already well known for its manual support capabilities. In versions 3+, major improvements have been made that will benefit both Pro and Free edition users.

If you’ve ever struggled to place a support in a tight space or been frustrated getting just the right angle to clear an overhang or thread that gap, it’s simply the most powerful support tool available.

In both versions of Lychee Slicer you have full control of your manually created supports. Manipulate supports individually or in groups, and control the parameters of everything you create including (but not limited to!) your mini supports, bracing, and parenting.

With the Pro version, an Advanced mode has been introduced for support editing and free-form support creation. This revolutionary toolset allows users to quickly manipulate in real 3D space each individual element of a selected support structure.

New clipping mode

The clipping bar allows users to view any portion of their 3D model from above or below. This is critical for support creation, especially in deep overhangs and on complex models.

The newest version of the clipping bar shows a cut-away slice of your model at any height. This allows users to seamlessly manipulate supports and makes the creation of hard-to see and internal supports an easy operation. This feature allows visibility of the interior of a hollow 3D model, but also the interior of models that have been dynamically hollowed within Lychee Slicer.

Pixel pipeline

The engine powering Lychee Slicer and our Pixel pipeline was carefully designed to give users the most accurate and powerful 3D preparation tool. We developed Lychee Slicer to be pixel-based rather than vector-based, because your 3D printer communicates in pixels of light broadcast through the LCD panel to cure each layer of resin that makes up a print. Because of this intentional development, our slicer will produce a more accurate slice than other tools, better capturing the fine and micro details common on intricate miniatures and figures.

Pixel Perfect slices previews (Pro)

While viewing a cut-away portion of a model with the clipping bar, users may now enable the Pixel Perfect mode. Each layer slice displayed on the screen will be displayed in 1:1 pixel perfect detail, showing users exactly what their printer will output for that layer. 

Hands down the best addition to your support creation toolbox. Advanced manual support users can ensure their smallest supports or fans will be precisely where they need to be. You’ll never build complex or mini supports without Pixel Perfect again!

Repairing 3D models

Models with structural or mesh defects are an ever present issue with 3D print preparation. These defects can result in printing errors or even total print failure. Lychee Slicer 3 provides one of the best solutions: an integration with Netfabb online* service.  Simply select the model that has been flagged by Lychee Slicer as non-manifold and press the repair button on the screen. 

Please note, a free Autodesk account and an internet connection are required for repair, as the model is uploaded, repaired, and then downloaded from the Netfabb service platform.

Adjustable support exposure, transition layers, and the ‘Elephant foot’ (Pro)

We love our resin printers, but dialing in small support tips can be challenging. Not enough exposure and the tip can break, too much curing and it’s hard to remove! With Lychee Slicer 3, you can increase the exposure time only for the supports to over-cure them without affecting the 3D model itself.

To save printing time and to reduce the ‘Elephant foot’ effect, the bottom print layer’s exposure time can be progressively reduced in Lychee Slicer. We’ve also added Resin Compensation tools in Pro for additional resin expansion mitigation.*      

*Only for supported 3D printers

Variable layers (Pro)

With the new variable layer function, you can define the layer thickness and all other slicing parameters for a specific range of layers. For example your slice can start at 100 microns per layer, then switch to 25 microns for a portion, and finish at 50 microns. With variable layers, you can save hours of printing time!

*Only for supported 3D printers

Import / Export Resin profiles

The best settings for a specific resin brand and it’s ideal calibration for your 3D printer is sometimes difficult to determine. That’s why Lychee Slicer lets you import and export your resin profiles, including profiles from other slicing software. Spend less time tinkering with new resin profiles and more time creating and printing!


It’s a massive addition, but you won’t see a new button. We’ve completed several speed enhancements in mesh load time and support generation/manipulation. For some actions, the speed is 10-15x faster, particularly noticeable on large, complex scenes and high-resolution models.

Please keep in mind that speed, while very important, does not take precedence over functionality. Our goal remains, providing the 3D printing community with the highest quality 3D file preparation program available! Our pixel based engine, means we manipulate huge volumes of data, and precision slicing takes time. We are constantly at work on the back-end of Lychee Slicer to improve the speed of these complex processes, and to keep your workflow the most efficient it can be!   

3D Printer simulator with banana scale!

Craning your neck to see the upside down print orientation of a model? Trying to remember which side is the front or the back? At some point we’ve all found ourselves asking how the model will be oriented in physical space.

Lychee Slicer 3 introduces a simulator mode with visual references for size and scale (banana & Coke can). These visual modes will display exactly how the model will look once it has printed and while it is printing, and of course you can see the preview of each slice on the simulated printer screen!

User interface

We’ve made multiple changes in the Lychee Slicer 3 user interface. We have streamlined several operations and made some of the harder to find functions more accessible. We will continue to iterate and improve on the UI and the overall user experience. We believe this is critical to the success of Lychee Slicer and the satisfaction of our users.
