TPU (thermoplastic polyurethane) is the material of choice when a printed part needs to flex, compress, or absorb impact without cracking — phone cases, gaskets, wearable components, flexible joints, vibration dampeners, and any application where PLA or ABS would simply fail. AMOLEN's Basic TPU delivers the core properties that make flexible printing practical: high elastic recovery so parts spring back to shape after repeated bending, and strong abrasion resistance for components that take wear over time. Made from U.S.-sourced virgin-grade materials and packaged in reusable vacuum-sealed bags for long-term storage. Available in ten colorways including nine solid options and one multicolor. TPU prints best at reduced speeds with a direct drive extruder — Bowden setups are not recommended due to inconsistent feed through a flexible tube path.
Available colorways:
Black — a clean matte black TPU. Reliable workhorse for functional flexible prints: cases, gaskets, brackets, and wearable components where color is secondary to performance.
Yellow — a warm, bright yellow for high-visibility flexible components and accent parts.
Cream Yellow — a soft off-white with a warm yellow undertone, muted and neutral for flexible parts where pure white would read too stark.
Rainbow Fruity Splash — a multicolor TPU blending bold, saturated fruity tones through a single strand. Brings color variation to flexible prints without requiring filament changes.
Light Green — a soft, fresh mid-range green for flexible decorative and functional parts.
Orange — a clean, saturated orange for high-visibility accents and flexible prints where color presence matters.
Solid Blue — a rich, deep blue in standard flexible TPU with consistent color across the spool.
White — a clean, neutral white for flexible applications requiring a minimal or base-layer appearance.
Solid Red — a bold, saturated red for flexible functional and wearable components.
Solid Purple — a deep, saturated purple for creative and decorative flexible prints.

🌵 Why Buy from VectorDesignsArizona?
We run a large and growing 3D print farm out of Tucson, Arizona — and the filaments we carry are the ones loaded in our own machines. As an authorized reseller, we only sell what we've personally used and relied on. Every material in our store has been tested in real production runs, not just sampled. When we recommend a filament, it's not a sales pitch, it's what's actually running through our printers right now.
