HQA PLA+ is part of the new breed of modified PLA materials to create a tough, easy to use high grade PLA filament. Manufactured exclusively using, Made in the USA NatureWorks' Ingeo 4043D PLA resin, the gold standard for 3D printing. Slightly modified, the filament retains the typical features of PLA, but makes it tougher and less brittle. Due to a low shrinkage factor PLA will not deform after cooling. Poly Lactic Acid is a biodegradable plastic made from renewable natural resources and one of the most popular materials for 3D printing.
