We only use high-end ethically sourced wood and PLA (Polylactic Acid) combination for our Wood/Plastic prints. Unlike most  thermoplastic polymers, PLA is derived from renewable resources like corn starch and sugarcane, making it environmentally  friendly due to its biodegradability. As a natural polymer, PLA is designed to substitute commonly used petroleum-based  plastics such as PET (Polyethene Terephthalate). It is also used as a decomposable packaging material. You can send us  your 3D files if you have a special project that requires to be printed using this exotic material, and we will help convert that  project into a real product.
