How to Print PLA?
PLA (Polylactic Acid) is one of the most popular materials in 3D printing. Easy to print, biodegradable, and available in a wide range of colors and finishes, it is especially favored by both hobbyists and professionals. However, to achieve optimal print quality, it’s essential to master printing parameters and understand the best practices.
Ideal Print Temperature
One of the first elements to consider is the print temperature. PLA is typically printed between 180°C and 220°C, but this range can vary depending on the manufacturer and any additives in the filament. A temperature that is too low may cause adhesion issues between layers and insufficient flow, while a temperature that is too high may result in blobs and unwanted strings. It is recommended to test different temperatures and gradually adjust to find the ideal configuration.
Bed Adhesion
The adhesion of the first layer is crucial to ensure the success of the print. PLA adheres well to most print surfaces such as glass, PEI, or BuildTak, but it may be necessary to use an adhesive solution such as hairspray, glue stick, or masking tape to improve adhesion. It is also important to correctly adjust the bed leveling so that the first layer is uniform and properly compressed against the print surface.
Print Speed
PLA can be printed at various speeds, generally between 40 and 80 mm/s. A speed that is too high can harm the quality of the details and lead to defects, while a speed that is too low can extend the print time without significant improvement in quality. A moderate speed, around 60 mm/s, is often a good compromise between speed and print quality.
Cooling and Ventilation
Cooling plays a key role in printing PLA. Good ventilation helps solidify each layer quickly, improving the quality of bridges and fine details. It is recommended to activate the cooling fan at least 80%, or even 100% after the first few layers. However, in some cases, such as printing tall parts or complex shapes, excessive cooling may cause layer separation.
Retract Settings
To avoid strings and blobs, it’s essential to properly configure retraction. A retraction distance between 2 and 6 mm is typically effective depending on the type of extruder (direct or Bowden). A retraction speed between 25 and 50 mm/s helps reduce defects while preventing nozzle clogging.
Humidity Impact
PLA is sensitive to moisture, which can affect print quality by causing bubbles and inconsistent extrusion. It is recommended to store filament spools in an airtight container with desiccant packets or use a dehydrator to remove accumulated moisture. Properly stored filament ensures smooth extrusion and successful prints.
Choosing the Right Filament
Not all PLA filaments are created equal. It’s important to choose high-quality filament from a reputable manufacturer. Cheap filaments may contain impurities or have an irregular diameter, which can cause jams and defective prints. Testing several brands helps to find the filament best suited for your printer and specific needs.
Conclusion
Printing with PLA is relatively simple, but it requires precise adjustments to parameters to ensure optimal results. By mastering temperature, adhesion, speed, cooling, and retraction, it’s possible to achieve accurate and strong prints. With proper moisture management and careful filament selection, PLA remains an excellent material for a wide variety of 3D printing applications.
