Here are some important factors to look out for when buying a new 3D printer:

1. Printing technology:
**FDM (Fused Deposition Modeling) ** is the most common 3D printing technique, suitable for beginners and regular printing tasks.
**SLA (Light Curing) ** For projects requiring higher accuracy and surface smoothness.
2. Modeling volume and platform:
Make sure the printer's modeling volume is large enough to accommodate your usual projects.
Considering the type of printing platform and the leveling method, automatic leveling can simplify the printing preparation process.
3. Printing speed and resolution:
Print speed usually depends on print quality, and higher speeds may sacrifice some details.
Resolution determines the level of detail in the print, and higher resolution provides clearer results.
4. Material compatibility:
Make sure the printer is compatible with the printing materials you want to use, such as PLA, ABS, PETG, etc.
Some printers also support special materials, such as flexible materials, metal filling materials, etc.
5. Ease of use and Software support:
Consider the ease of use of the printer, including the setup process, operating interface, and maintenance.
Make sure the printer has reliable software support and is equipped with easy-to-use slicing software.
6. Functions and features:
Automatic leveling, double extrusion, touch screen interface and other features enhance the printing experience.
Some printers have advanced features such as Wi-Fi connectivity and resumable printing.
7. Support and community:
Ensure you have access to manufacturer support and repair services.
Participating in an active community can help solve problems and share experiences.
8. Price and budget:
Determine your budget range and choose a printer within that range with the right performance and features.
To sum up, when choosing a 3D printer, you need to consider printing technology, modeling volume, printing speed and quality, material compatibility, ease of use, functional features, support, and budget to ensure that you choose the best printer for your needs.
