Lychee Slicer 6 Public Beta – The beginning of a new area!

We’ve been quiet about Lychee Slicer updates in recent months. The reason is simple: we’ve been working hard on the future to prepare for the arrival of Lychee Slicer 6!

On the agenda: the rewriting of significant portions (which are invisible to you but crucial for its future), and the addition of new features that will change your everyday 3D printing experience.

We’re so excited about these new features, and those to come, that we have decided to introduce them to you in a cycle of public Betas. This cycle is available only on our Discord. Some updates will bring new features, others will fix bugs and bring other improvements. Of course, we are waiting for your feedback to make all these changes even better!

If you wish to follow our development more closely and access our betas, we invite you to join our Discord server.
Our Discord community is very active and most of the team is present daily alongside our users.

About the Public Beta

Upcoming versions of Lychee Slicer within this public beta are accessible to all users, whether Pro or Free. However, some features are only available to Pro users or users on a Pro trial.

While we’ve extensively tested the application, some changes are significant, and instabilities or areas for improvement may persist, hence the Beta designation. We believe it’s possible to use the new features in production, but please remember that this is still a beta.

You can uninstall a beta version anytime and revert to a previous stable version.

Lychee Slicer Resin: new support engine

Here’s our new generation of supports! Designed for both manual and automatic supports, they offer a more organized structure and significantly increased rigidity.

This ensures higher print quality by reducing the risk of layer shifts, especially for large 3D prints.

Model by 3dsqulpts

Pro: Automatic parenting

In action a support placement that always connects to the same support, the one closer to its position. Model by Loot Studios.

Thanks to its structured system, supports will automatically interconnect with existing supports, minimizing the presence of long supports hanging in the air.

Pro: Support bracing, adapted to the model

Notice how the supports and bracings can stabilize even tiny parts to print! Model by 3dsqulpts.

Bracing connects all supports together to stiffen and stabilize them. With our innovative new system, all your supports will be interconnected to prevent any movement during 3D printing. Even an isolated support will be reinforced to increase its stability.

Pro: A bracing editor to suit your needs

Because supporting a small or large 3D model, or preparing an organic or mechanical model requires different approaches, Lychee Slicer offers a bracing editor with pre-configurations. With just a few clicks, define the behavior of your bracings based on their structure and height.

Pro: Reduce print failures!

The print had a local failure at the beginning of supports. But the grid structure made up for it!

Nobody likes a failed print, least of all us! Continuing our journey for successful printing every time, adding these grid supports allows, through their structure, to address specific problems, especially when supports fail to adhere correctly.

Pro: Save on resin

On the left, the models with grid supports with 11.69 mL of resin for supports. On the right, the classic supports with a total of 44.64 mL of resin. Model by 3dsqulpts

With its unified structure, you can use thinner supports than the default ones, for example, reducing from 1.3mm to 1.0mm in diameter, using 0.8mm bracing, and, most importantly, drastically reducing the number of supports needed. Between traditional supports and grid supports, you can save up to 30% of resin for two identical models!

Pro: Update your old supports to grid supports

On the left, the original model, created with Lychee Slicer 5.4. On the right, the supports have been updated to use the grid supports, except the ones that reach the arm and are custom-made. Model by Fotis Mint

You can convert your old supports to grid supports in just a few simple steps. Activate grid mode, select all the supports, go to the Supports menu, recalculate them (ALT+R), and finally, add automatic bracing: your supports will now be up to date!

Pro: Mix free supports with grid supports

In white, supports in free mode. All the other supports are in grid mode. Model by Fotis Mint

Since this new system differs from the old one, you can use either or mix both! Grid supports are constrained to regularly spaced points, so you may want supports placed more precisely or specifically. Press the ALT key while moving a support to remove it from the grid constraint: simple and fast.
Functions like “Make Support Pillar” or “Make Support Vertical” will also disengage the function.

Free: Improved bracing

On the left, old bracing, on the right, improved bracings. Model by Loot Studios.

The free version also benefits from improvements to bracing, offering a much more effective connection between supports than the old system. However, if you still need to try the Pro version, activate your trial period to discover grid supports!

Grid Supports Tips!

  • By default, supports in Lychee are thick: feel free to use 1mm supports, especially if your vat film is nfep/acf type. The denser the grid, the smaller the diameter you can use. However, be mindful of mechanical constraints (weight, peeling).
  • Each object on the build plate has its own grid and therefore its own density, which is handy if you mix objects of different types or sizes!
  • Watch out for the spacing between grid points. A significant spacing will force aggressive support branching, potentially resulting in many attached points and thus applied forces. Wider support diameters may be necessary.

Lychee Slicer for Filament 3D printers

The free version also benefits from improvements to bracing, offering a much more effective connection between supports than the old system. However, if you still need to try the Pro version, activate your trial period to discover grid supports!

PRO: Ironing for filament printing

Probably the most anticipated feature, here’s surface ironing, available in two flavors: classic and fast. You’ll achieve a much better surface finish for your flat surfaces, ideal for top layers, especially for design objects or mechanical parts.

Hidden seams for filament printing

Layer junctions leave a mark that can be unsightly, especially with glossy filament. Easily hide these junctions in the model’s corners with a single click, print, and enjoy models with flawless surface finishes.

PRO: Boolean for filament printing

Easily add and subtract objects during slicing for your filament printers, whether to create a base suitable for a model without one, make a notch for hanging your prints on the wall, or insert magnets without using 3D modeling software.

Improved Supports at slice

Lychee Slicer offers automatic supports at the time of Gcode generation (“at slice”), which have been greatly improved with numerous options. For example, generating supports that only start from the build plate. Additionally, rafts have been added under the supports for better adhesion.
