The Kimya Tough PLA-HI 3D filament is a biosourced polymer obtained from corn starch. Polylactic Acid-HI (PLA-HI) is a "High Impact" filament offering increased impact resistance: it was formulated to be five times more resistant to impact than standard PLA. PLA is easy to print and is odorless. It can be used to create functional prototypes, spare parts, architectural models and in other forms of modeling. The Kimya Tough PLA-HI 3D filament has the following properties.
• Impact resistance.
• Biosourced material.
