Setting up a model to 3D print requires a slicing software – think of it as a print menu. You can choose settings for your model and export the G-code file that tells the 3D printer what to do on each layer of your print. If you’re interested, feel free to practice each setting while following along with this guide.
We based this interactive guide on Craftware, a free slicing software that is designed to be used with Craftbot 3D printers. If you are looking for a guide for a different slicing software, have questions about your new 3D printer, or need advice or troubleshooting help, don’t hesitate to reach out to info@fluxspace.io and we would love to help you!

The Basics of 3D Printing
Setting up a model to 3D print requires slicing software – think of it as your printer's menu. This software allows you to choose settings for your model and export a G-code file, which tells the printer what to do on each layer.

Key Parts of a 3D Printer
- Print Bed / Build Plate
- Extrusion Nozzle
- Bowden Tube (for filament)
- Heating Element
- Interactive Touchscreen
- Fan
- Z Axis
Getting Started in Craftware
- Open a 3D Model
Click the folder icon (upper left) to import your 3D model. You can design your model in a program like TinkerCAD or download one from thingiverse.com. - Explore the Tabs
- CAD: Edit and transform your model using toolbars like Object, Transformation, and Support. Don’t forget to hit Apply after making changes.
- Manufacturing: Adjust print quality, speed, strength, and density settings. When ready, click SLICE to export.
- GCODE: Preview the printer path, duration, and material usage before printing.
Using Presets in Craftware
Craftware offers several preset menus:
- Smart, Easy, Default, Draft, and Fine:
Simplified interfaces using sliders for quick setup. You can always click Reset to return to default settings. - Vase Mode:
Toggles a style that prints only the outer perimeter of your object, creating hollow, artistic models. - Advanced Settings:
For experienced users, full manual control of every setting is available.
Key Print Settings
Materials & Filament
3D printer filament is usually plastic but can be specialized (e.g., glow-in-the-dark, conductive). Different materials have different melting points and properties.
Shells (Walls, Top, Bottom)
Shell thickness is measured in layers or millimeters. More layers = stronger model; fewer layers = faster print.
Extrusion Width
Measured as a percentage of nozzle diameter (standard is 0.4mm). Smaller nozzles = higher detail; larger nozzles = faster prints.
Travel, Retraction & Z-Hop
- Travel: When the nozzle moves without printing.
- Retraction: Prevents filament stringing during travel.
- Z-Hop: Lifts the nozzle during travel to avoid damaging delicate prints.
Feed Rate & Print Speed
Measured in mm/s.
- Too slow: Overheating and sagging.
- Too fast: Weak prints with holes or streaks.
Research is key for optimal results based on your filament type.
Temperature Settings
- Filament Temperature: Controls the heat for extrusion.
- Bed Temperature: Keeps prints adhered to the bed.
Both must be balanced to avoid warping or poor adhesion.
Infill Patterns
Choose from patterns like:
- Zig Zag, Lightning (Low strength, fast print)
- Grid, Triangles, Tri Hexagon (High 2D strength)
- Octet, Cross 3D, Gyroid (High 3D strength)
Each balances material usage, speed, and strength.
Infill Percentage
Determines how solid your model is:
- Low (5–20%): Great for prototypes and fast prints.
- High (50–100%): Ideal for functional parts and durability.
Support Structures
Support columns help with overhangs and can be removed post-printing. Customize the overhang angle (standard: 45°) to control where supports are generated.
Adhesion Options
- Brim: A thin layer around the base of your model. Good for flat-bottom prints.
- Raft: A full platform underneath your model. Useful for small or unstable prints.
Layer Thickness
Layer height affects quality and speed:
- Smaller layers: Higher detail, longer print time.
- Larger layers: Faster prints, lower resolution.
Ironing
A Craftware-exclusive option that adds a thin smoothing layer on the top of your print. Optional, but great for improving surface finish without affecting print time.
