Lychee Slicer

Lychee Slicer is a model-preparation and printer-configuration app for resin and filament 3D printing. It is best suited to makers who use both processes or want printer controls and model preparation in one workflow. Lite covers the basics for free, but Auto-Support and full Multi-Plate are paid features.

Overview

Lychee brings resin and filament preparation together, with print-setting previews and printer configuration. The maker says it is compatible with more than 750 printers, a useful breadth for people with mixed equipment; that does not guarantee every connection method will work with every machine. For compatible filament printers, communication is available through Klipper or OctoPrint, while Wi-Fi sending depends on the printer model.

Cloud synchronization carries settings across machines, and automatic local backups offer a separate safeguard. The integrated Lychee Library brings creator-supplied pre-supported models into the slicer workflow, but its commercial-use restriction matters: those models cannot be used commercially without the creator’s approval.

Key features

Resin and filament tools

Resin preparation includes custom and grid supports, exposure settings, AR preview and one-click hollowing. Filament users get printer profiles, support management, seam optimization and real-time preview. This combination is Lychee’s strongest case: users switching between resin and filament can keep both workflows in one application. Someone who needs only a narrow set of tools for one process may not benefit as much from that breadth.

Printer and file support

Lychee Slicer 8 adds multi-object 3MF Production Extension support, Goo v5 support for Anycubic Jupiter 2, and LGS support. The product also includes auto-supports, printer control, print monitoring, multi-material tools, model repair and multi-material printing. These capabilities widen its role beyond arranging a model for a single print, though connection options remain printer-dependent.

Help and Library

Lychee provides tutorials, guides, ticket support and live chat. Plus subscribers receive priority technical support, which makes the paid tier more attractive to users who rely on help resolving workflow problems. Library adds access to pre-supported models, but its no-commercial-use-without-creator-approval term makes it a poor fit for commercial production unless the creator grants permission.

Pricing

Lychee uses a freemium model, with a free plan and a 30-day trial. The Lite plan costs nothing and includes limited Multi-Plate, ads on export, and Windows, macOS and Linux support. It is a practical starting point for evaluating the workflow, but the plate limitation and export ads are meaningful trade-offs for regular use.

Plus has custom pricing, billed at €99.90 + local taxes yearly (€8.33 / month). It adds Auto-Support, full Multi-Plate, priority technical support and exports without ads. This is the relevant plan for frequent users who need those preparation tools; it retains the same three desktop platforms.

Plus & Library has custom pricing, billed at €199.90 + local taxes yearly (€16.66 / month). It includes the Plus features plus 2500 pre-supported models, 120 creators and unlimited downloads. The larger Library offering suits users who want creator-prepared models in the slicer, but the commercial-use restriction may rule it out for paid work without creator approval.

Platforms

Lychee Slicer runs on Windows, macOS and Linux. Its broad desktop coverage suits users choosing between the three major desktop systems, while printer connectivity still depends on compatible hardware and, for Wi-Fi sending, the model.

Who it's for

Choose Lychee if you prepare both resin and filament prints, want a single workflow for their distinct support and preview tools, or value printer configuration and Library integration. Lite is suitable for trying the workflow or occasional use; users who need Auto-Support and full Multi-Plate should budget for Plus. Look elsewhere if commercial access to Library models is central and creator approval is unavailable, or if the paid features do not justify an annual subscription for your workflow.

Pros and cons

Pros: Resin and filament tools share one application, including one-click hollowing and seam optimization for their respective workflows.

Pros: Support for more than 750 printers and Klipper or OctoPrint communication on compatible filament printers broaden its usefulness across equipment.

Pros: Cloud settings synchronization and automatic local backups help preserve configuration across machines.

Cons: Lite limits Multi-Plate and adds export ads; Auto-Support and full Multi-Plate require paid Plus.

Cons: Library models are not commercially usable without creator approval, a material constraint for professional users.

Cons: Wi-Fi sending depends on the printer model, so broad printer compatibility does not ensure that convenience for every user.

Alternatives

For a broader 3D Slicer Software shortlist, compare Lychee with other slicers before settling on its combined resin-and-filament workflow. The 3D Printing Software list is the wider category starting point.

GrabCAD Print is worth considering if its free Standard plan, per-user annual subscription and Stratasys printer support match your setup; Pro is also offered at 5000.00 USD per.

Verdict

Lychee Slicer is a strong fit for makers who move between resin and filament printing and want preparation tools, printer configuration and previews under one roof. Its main advantage is that cross-process breadth; its main reasons to look elsewhere are the annual cost of Auto-Support and full Multi-Plate, and the Library’s commercial-use restriction without creator approval.
