How do you ensure consistency in print settings across different 3D printers for complex geometries?

In order to maintain consistent print settings for complex geometries across different 3D printers, I recommend following a strict control process, starting from ensuring the material dryness to calibrating the print. Since I create and design parts for aircraft, it is crucial that everything I print turns out perfect.

Cuando comence a imprimir piezas más complejas, me di cuenta de que cada impresora parecía tener su propia "personalidad" y que imprimir en 3D es como cocinar, a veces hay platos (modelos 3D) que requieren mas o menos ingredientes (parametros) que otros. Lo que funcionaba bien en una, no siempre salía igual en otra. Lo que he estado haciendo es llevar un registro de los ajustes que uso para cada figura/impresora y cuando la pieza tiene ensambles, separo las áreas de la pieza donde se encuentran esos ensambles y las imprimo por separado para ver como se comportan. Recurrir a los apuntes, siempre es un buen punto de partida para empezar a imprimir correctamente.

Know Your Printer's Personality: Each printer has its quirks. Understand how yours behaves with different settings and materials to improve consistency. Keep Detailed Notes: Document your print settings and results. This helps troubleshoot issues and replicate successful prints. Test Assemblies Separately: For complex parts, print sections individually to fine-tune settings and ensure perfect fits. Regular Calibration: Regularly check and adjust your printer's calibration to maintain performance and prevent issues. Calibrate for New Materials: Run calibration prints with new filaments, as each material has unique settings for optimal results. By mastering these basics, you’ll achieve reliable and high-quality 3D prints consistently.

To maintain consistent 3D prints, create detailed profiles for each printer in your slicing software, covering nozzle size, layer height, print speed, and temperatures. Save and share these profiles with your team, including explanations and usage notes to ensure uniformity and aid troubleshooting. Adjust firmware settings like pressure advance, acceleration, and jerk for each material and nozzle diameter, using EEPROM or start_gcode for storage. Run calibration prints when using new filaments, as each material has unique settings. Regularly review and update profiles to ensure reliability and precision across all machines.

Achieving consistency in 3D printing requires repetition and refinement. Conduct test prints on each printer using the same file and settings. Analyze results for discrepancies in dimensions, surface finish, or structural integrity. Adjust settings to match desired outcomes. This iterative process fine-tunes each printer to behave similarly, ensuring consistent quality across different machines. Regularly revisit this process, especially when changing materials or settings, to maintain high standards. Consistent testing and adjustment are key to reliable, high-quality 3D prints.

Understanding the complex relationships between print defects and settings and environmental variables should be derived and known to provide a feedback loop for micro adjustments to ensure uniformity between manufacturing sites. Printing scannable calibration parts with challenge features is a method to compare and quantify printer to printer and printer to control variation.
