🧩 Module 5: Introduction to Slicer Software

🖨️ Focus: Learning how to prepare 3D models for printing using different slicer software

✅ Lesson Summary

A slicer acts as the bridge between your 3D model and your printer. It “slices” your 3D design into layers and generates instructions—G-code or proprietary formats—that your printer can follow. In this lesson, you’ll explore 6 popular slicers across FDM and resin workflows, learning how to prepare, configure, and export print jobs properly.

🎯 Learning Objectives

By the end of this module, students will be able to:

• Define what slicer software does and why it’s essential for 3D printing

• Navigate the interfaces of each featured slicer

• Import models, configure print settings, and export files correctly

• Identify slicer options optimized for different printing technologies (FDM vs. resin)

• Choose the right slicer based on printer compatibility and features

🖥️ 1. Orca Slicer

✅ Best for: FDM, Klipper-based printers, Bambu Lab, Voron, Creality K1

Overview:
Orca Slicer is a powerful, community-driven fork of Bambu Studio designed to support many printers beyond Bambu Lab. It provides a streamlined UI, high-speed slicing, and built-in calibration tools for fine-tuning quality.

• Flow calibration, pressure advance, and A/B test prints

• Visual G-code preview

• Auto-orientation and variable layer height

Workflow Steps:

1. Import .STL or .3MF

2. Select printer profile (auto-detects Bambu models, allows custom profiles)

3. Adjust layer height, infill, temperature, speed, supports

4. Preview layers

5. Export to SD card or send via LAN/Wi-Fi (for supported printers)

Workflow Steps:

1. Import .STL, .OBJ, or .3MF

2. Choose or configure a printer profile

3. Use recommended or custom settings for speed, temperature, supports, and infill

4. Slice and preview

5. Export G-code or send to printer via USB/network

🖥️ 3. Repetier-Host

✅ Best for: Multi-extruder setups, advanced control of G-code, and remote monitoring

Overview:
Repetier-Host is a versatile slicer and printer host with integration for multiple slicers (CuraEngine, Slic3r, PrusaSlicer). It’s ideal for users who want precise control and monitoring features.

Features:

• Direct integration with printers via USB or Repetier-Server

• Multi-slicer engine support

• 3D and layer-by-layer preview

• Advanced control terminal for G-code

• Custom scripts and macros

Workflow Steps:

1. Import a 3D model

2. Select slicing engine and configure settings

3. Preview G-code and simulate

4. Send directly to printer or export G-code

5. Monitor real-time prints via USB/web interface

🖥️ 4. Halo Box Slicer (Creality HALOT Series)

✅ Best for: Resin 3D printing on Creality HALOT LCD printers

Overview:
Halo Box is Creality’s proprietary slicer for its resin printer series. It focuses on preparing high-detail SLA/LCD prints with supports and optimized exposure times.

Features:

• Model repair and auto-layout

• Manual and automatic support generation

• Hollowing and drainage holes

• Anti-aliasing and bottom exposure tuning

• Compatible with .ctb file format for HALOT devices

Workflow Steps:

1. Import .STL

2. Orient model and scale if needed

3. Hollow the model and add drain holes

4. Add supports (manual/automatic)

5. Slice and preview exposure layers

6. Export to USB or HALOT Cloud

🖥️ 5. FormLabs PreForm

✅ Best for: Professional SLA printing with FormLabs printers

Overview:
PreForm is FormLabs’ proprietary slicer for its SLA and LFS printers like the Form 3+, Form 4, and Form Wash/Cure systems. It automates much of the slicing process while allowing expert-level customization.

Features:

• Auto-orientation and intelligent support generation

• Material-specific tuning (Grey Resin, Tough, Castable Wax, etc.)

• Printability heatmap for weak features

• One-click print layout optimization

• Integration with Form Wash and Form Cure

Workflow Steps:

1. Open or import model

2. Select material and layer resolution

3. Auto-generate supports and verify layout

4. Send to printer over network

5. Post-cure according to resin profile

🖥️ 6. Chitubox

✅ Best for: Budget LCD resin printers (Anycubic, Elegoo, etc.)

Overview:
Chitubox is the most widely used slicer for consumer resin printers. It offers extensive manual control over supports and slicing behavior, including pixel-level anti-aliasing and resin volume estimates.

Features:

• Manual and auto support generation

• Hollowing, infill patterns, and drain holes

• Real-time slicing and exposure previews

• Compatible with .cbddlp, .photon, .ctb, etc.

• Advanced anti-aliasing and grayscale exposure

Workflow Steps:

1. Import .STL

2. Orient and scale model

3. Hollow the object if needed

4. Add supports and base

5. Slice and export in the correct format for your printer

6. Copy to USB stick for transfer to printer

🧠 Summary

Slicer software is essential to bridge your 3D model with your printer. Each application has its strengths:
