What is G-Code?

One essential step in 3D printing is converting 3D files into G-code, which is the machine-readable format that 3D printers can understand and execute. Without this crucial step, it's impossible to translate a 3D model into a physical object.

The process of converting 3D files into G-code known as slicing , typically requires a slicer , which is an essential component of the 3D printing workflow. Some popular slicers and their supported formats include:

- Cura: a free and open-source slicer developed by Ultimaker that supports STL, OBJ, DAE, and AMF file formats, and runs on Mac, Windows, and Linux.

- Simplify3D: a commercial software that supports STL, OBJ, AMF, and 3DS file formats and is compatible with most 3D printers.

- PrusaSlicer: a free and open-source 3D printing slicer developed by Prusa Research in the Czech Republic, supporting STL, OBJ, FBX, 3DS, AMF, and other file formats.

- IdeaMaker：3MF、STL、OBJ、OLTP

The process of converting flies to G-Code

Here are the general steps to follow when converting a file to G-code:

1. Create or import a 3D model of the part you want to machine.

2. Define the machining operations you want to perform on the part, such as roughing, finishing, drilling, etc.

3. Set the cutting parameters, such as spindle speed, feed rate, and depth of cut.

4. Generate the toolpath for each operation using your CAM software.

5. Post-process the toolpath to create the G-code program that your CNC machine can understand.

However, if your file doesn't fit any of these 3D formats , you may need a format converter. There are also many format converters available on the market, such as our 3DPEA Converter, which not only converts 2D files to 3D models , but also performs 3D file format conversions. It operates entirely online, without requiring any downloads or installations, and is completely free.
