Polymaker PolyMax Tough PETG Black is a high-performance engineering filament that takes the baseline properties of PETG and significantly elevates its impact toughness through Polymaker's Nano-reinforcement technology. While standard PETG is already a step above PLA in toughness, PolyMax Tough PETG is engineered for demanding applications where parts must absorb significant mechanical shock or repeated impact loading without fracturing. It is the go-to PETG option when standard PolyLite PETG is not tough enough.

PolyMax Tough PETG is ideal for drone frames, protective covers and guards, tool handles, snap-fit and press-fit mechanisms, impact-exposed jigs and fixtures, and any application requiring the chemical resistance of PETG combined with genuinely high impact strength. The 750 g spool is a practical size for engineering projects and prototype runs. Black color is the standard industrial choice for engineering-grade materials.

Key features

• Significantly enhanced impact toughness over standard PETG through Polymaker's Nano-reinforcement technology - designed for shock-loaded applications.
• Retains PETG's characteristic chemical resistance, moisture tolerance and temperature performance alongside the improved toughness.
• Ideal for drone frames, protective guards, tool handles, snap-fit mechanisms and impact-exposed functional parts.
• Prints reliably with low warping tendency, similar to standard PETG, on most FDM 3D printers.
• 750 g spool is a practical engineering quantity for prototyping and small production runs.
• Step up from PolyLite PETG when standard toughness is not sufficient for the application demands.

Compatible with: Most FDM 3D printers with a 1.75 mm filament path and hotend capable of 220-250 C
