Lychee Slicer for Mac

Quick overview

Lychee Slicer is a free macOS application that streamlines resin 3D printing workflows. It converts 3D models into files that resin printers can use, while providing tools that help both newcomers and experienced makers get reliable results faster.

Notable strengths

• High-quality output thanks to advanced slicing routines that focus on print accuracy and surface finish
• Built-in model repair and wide support for common 3D file types
• User-friendly layout suitable for first-time users and power users alike
• Multiple printer profiles plus adjustable settings for tailored workflows
• Live preview and layer-by-layer visualization so you can verify settings before sending a print

Core capabilities explained

Slicing: The app transforms STL/OBJ models into printer-ready slices and supports exporting in formats many resin printers accept. Its slicing engine optimizes layer geometry to reduce common print defects.

Printer profiles and settings: Preconfigured profiles let you match popular printers immediately, while manual controls let you tweak exposure times, layer thickness, lift speeds, and other parameters to dial in results for specific resins and machines.

Model tools and preview: Repair utilities help fix common mesh issues (holes, flipped normals, non-manifold edges). The integrated preview shows exact layer outlines and support placements so you can confirm everything before starting a job.

How to get started quickly

1. Import your 3D file (STL or OBJ).
2. Choose or customize a printer profile that matches your machine.
3. Adjust exposure, layer height, and other parameters to suit your resin and desired quality.
4. Inspect the model with the layer preview and fix any mesh errors.
5. Export the prepared file and send it to your printer.
