PLA Filament – Properties, Benefits & Applications in 3D Printing

PLA filament (Polylactic Acid) is one of the most popular 3D printing materials thanks to its easy handling, high printability, and eco-friendly nature. PLA is biodegradable and ideal for beginners, model making, prototypes, and decorative parts.

Benefits of PLA Filament

• Easy to process with excellent printing behavior
• Low shrinkage, minimal warping
• Biodegradable and environmentally friendly
• Available in many colors and special variants
• Suitable for decorative, detailed prints
• Post-processing by sanding, gluing, or painting is possible

Printing & Material Properties

PLA is easy to print, does not require an enclosed chamber, and can be used even on printers without a heated bed. Its low shrinkage makes it perfect for detailed models and fine structures.

Optimal Print Settings for PLA

• Nozzle temperature: 190–220 °C
• Heated bed: 0–60 °C (optional, depending on the printer)
• Build chamber: open or closed
• Cooling fan: 50–100% for optimal surface quality
• Speed: 40–80 mm/s

Tip: For especially smooth surfaces, PLA can be lightly sanded or post-processed after printing.

Typical Applications of PLA Filament

• Model making and miniatures
• Prototypes and design models
• Decorative objects and figures
• Art and DIY projects
• Educational and experimental projects
• Household items with low mechanical stress

PLA vs. ABS – When Is PLA the Better Choice?

PLA is easier to print, more dimensionally stable at room temperature, and more environmentally friendly. PLA is the best choice when:

• Detailed and decorative objects are required,
• lower temperature resistance is sufficient,
• easy printing with no warping is important,
• a biodegradable material is desired.
