SUNLU was established in July 2013 during the rapid growth of the consumer 3D printing industry. Rather than manufacturing printers themselves, the company concentrated on solving one of the biggest challenges in desktop 3D printing: producing consistent, affordable, and reliable printing materials. As desktop printers became increasingly common, SUNLU expanded its product lineup beyond PLA filament to include engineering materials, resin printing supplies, and environmental control products such as filament dryers. Today the company operates multiple production facilities in China, maintains a global distribution network, and has expanded into Europe through a German branch office. According to the company, it has 36 worldwide distribution locations. [1]

According to the company, the name SUNLU is inspired by “Sunshine.” The brand describes sunshine as representing life, creativity, and innovation, reflecting its goal of making 3D printing easier and more accessible through dependable products. [1]

SUNLU states its mission as:

Driving Sustainable Development in the 3D Printing Industry.

The company emphasizes:

• Continuous research and development

• High-quality manufacturing

• Affordable pricing

• Sustainable production
