Explore NinjaTek filament
NinjaTek makes flexible 3D printing materials across several grades, from soft-touch Chinchilla TPE and flexible NinjaFlex to faster-printing Cheetah TPU, conductive Eel TPU and rigid Armadillo TPU. Compare hardness, material properties and manufacturer print guidance before choosing a filament. Armadillo is marked for discontinuation after inventory depletion on its product page.

NinjaTek’s filament range includes flexible TPUs and TPEs with different hardness, feel, conductivity and printing behavior. Compare the exact grade and its current manufacturer guidance rather than treating all flexible materials as interchangeable.
NinjaFlex 85A TPU
Flexible, abrasion-resistant TPU with a low-friction exterior intended to help feeding. NinjaTek lists 660% elongation at break and recommends slower print speeds than Cheetah.
NinjaFlex product detailsNinjaFlex Edge 83A TPE
A flexible grade with a low-friction exterior and rebound; the manufacturer describes it as more printable than NinjaFlex. Its product page lists 20–30 mm/s for top and bottom layers and 30–50 mm/s for infill.
NinjaFlex Edge product detailsChinchilla 75A TPE
A soft-touch, matte material with a low-friction exterior. NinjaTek says it was tested to be skin-safe using the EpiDerm Skin Model; the manufacturer lists 225–235 °C extrusion and room temperature to 40 °C for the platform.
Chinchilla product detailsEel 60D TPU
A flexible, conductive and static-dissipative grade. NinjaTek lists 355% elongation and guidance of 220–230 °C extrusion, room temperature to 45 °C platform, 15–20 mm/s top and bottom layers, and 45–60 mm/s infill.
Eel product detailsCheetah 95A TPU
A tougher, faster-printing flexible TPU. NinjaTek lists 580% elongation and prints above 60 mm/s; its specific guidance is 225–250 °C extrusion, room temperature to 50 °C platform, 25–45 mm/s top and bottom layers, and 50–80 mm/s infill.
Cheetah product detailsArmadillo 75D TPU
A rigid, wear-resistant TPU. NinjaTek says it will be discontinued once inventory is depleted, so verify current product status with the manufacturer. Its listed guidance is 210–230 °C extrusion, room temperature to 50 °C platform, 20–30 mm/s top and bottom layers, and 35–60 mm/s infill.
Armadillo product details and statusBeyond the flexible grades above, NinjaTek’s technical comparison chart also reports data for Alloy 910, Nylon 645, ABS and PLA. The chart is a performance comparison and does not confirm current availability; consult the manufacturer for product status and detailed guidance. Manufacturer product pages offer additional sizes and options; check the exact grade, spool size, print settings and printer compatibility before ordering.
Manufacturer print guidance
These are starting recommendations, and NinjaTek notes that every printer may need adjustments. It suggests glue and/or blue painter’s tape when not using a heated bed, a cooling fan from layer 2 if available, and notes that temperatures can vary with filament diameter, nozzle diameter and layer height. See the manufacturer’s full printing guidelines and technical specifications.
