3D Printing - getting started

Key terms/overall process

1. Slicing: Before printing, a digital model (usually in STL or OBJ format) needs to be 'sliced'. Slicing software, like PrusaSlicer or Cura, divides the model into thin horizontal layers and generates a path for the printer's nozzle to follow. This process converts the model into a G-code file, the language that 3D printers understand.

2. Choosing Settings: Setting selection is crucial for a successful print. Key settings include:

   • Layer Height: Determines print resolution. Lower layer height increases resolution but also print time. 0.2 is sufficient for the vast majority of models, and 0.3mm is recommended for fast print times and prototypes. 0.1 is best for high-detail models (such as miniatures).

   • Infill: Dictates the internal structure density. Higher infill increases strength but uses more material (and increases print time). For decorative items, 5-15% infill is usually sufficient, around 20% is good for functional objects, and higher infill is needed for structural strength.

   • Print Speed: Balancing speed and quality is vital. Faster speeds mean quicker prints but can reduce detail and accuracy.

   • Temperature Settings: Optimal temperatures for the nozzle and bed vary based on the material used. Please use the provided profiles inPrinter Profiles.

3. Exporting: After slicing, the G-code file is exported to the printer. This can be done via SD card, USB, or direct connection, depending on the printer's capabilities.

4. Post-Processing: After printing, models may require support removal, deburring, or additional finishing touches like sanding or painting.
