Selective Laser Sintering (SLS) is one of the mainstream additive manufacturing technologies. Its commonly used materials are primarily petroleum-based powders such as PA and TPU, and the production process generally suffers from high energy consumption and high carbon emissions. Polylactic Acid (PLA) is a bio-based polymer derived from renewable resources, offering thermoplasticity and biodegradability.
eSUN has developed China's first PLA powder suitable for powder bed fusion — S-PLA. Its raw materials are entirely sourced from renewable bio-based feedstock, featuring low sintering temperature, low carbon footprint and rapid forming, providing a sustainable alternative to PA12 and other petroleum-based powders.
Raw materials entirely from renewable bio-based sources, distinct from traditional petroleum-based powders, achieving low-carbon sustainability from the source.
Melting temperature of approximately 175°C, significantly lower than petroleum-based materials (e.g., PA-12), effectively reducing print energy consumption.
Carbon footprint reduction of up to 89%, aligning with green manufacturing and sustainable development goals.
Low moisture absorption rate, fast forming processing, and excellent model performance.
Polylactic Acid (PLA) is derived from renewable resources such as corn and sugarcane, with full biodegradability and carbon footprint reduction of up to 89%.
Melting temperature (~175°C) is significantly lower than petroleum-based materials (e.g., PA-12), reducing print energy consumption by over 30%.
The production process uses green solvents that can be recycled, with no toxic gas emissions throughout the entire process.
Low moisture absorption rate, fast forming processing, and excellent model performance.
Tested S-PLA demonstrates high biocompatibility, suitable for medical and healthcare applications.
eSUN has developed a PLA powder preparation process featuring spherical particles, appropriate particle size, good bulk density and green health properties, yielding the powder product best suited for SLS technology — S-PLA. This is China's first PLA powder suitable for powder bed fusion, providing a more environmentally friendly and sustainable material choice for SLS technology.
