About our GraviTrax expansion sets production method:
The PLA filament we use for printing our GraviTrax compatible tiles is non-toxic and made from natural components (corn starch), making it biodegradable at high composting temperatures and great if you’re looking to make a more eco-conscious purchase. Comparable to PET plastics – More than 95% of the world’s plastics are created from natural gas or crude oil. Fossil fuel-based plastics are not only hazardous; they’re also a finite resource.
Our used PLA material for our 3D printed GraviTrax parts presents a functional, renewable, and comparable replacement. PLA requires 65% less energy to produce than traditional, petroleum-based plastics. It also emits 68% fewer greenhouse gases. The material is lightweight and environmentally friendly.
