Heavy-Duty 3D Printed Leg Joint / Hip Brackets for KEYi Tech Loona Robot (Pair - Left & Right) | Siraya Tech Blu Nylon Mecha Engineering Resin

Restore Your Loona Robot with Industrial-Grade Engineering Resin

If your KEYi Tech Loona AI Petbot has suffered from a limp leg, inability to stand, or a snapped internal leg mount, you are facing the single most common mechanical failure on this robot. These circular load-bearing leg/hip joint brackets support the entire weight of Loona and absorb continuous shock from stomping, dancing, and sudden movements—causing the original factory plastic parts to crack under stress.

We offer a precision-manufactured, heavy-duty replacement pair (Left + Right leg brackets) 3D printed using Siraya Tech Blu Nylon Mecha White—a specialized, high-hardness engineering resin formulated specifically for load-bearing mechanical parts, gears, and joints.

Why Material & Printing Process Matter

Standard hobbyist 3D prints (using basic PLA filament or standard brittle photopolymer resins) cannot survive the torque and weight loads of Loona’s leg actuators. To ensure structural integrity, these parts are produced under strict temperature-controlled conditions (>25°C) using Siraya Tech Blu Nylon Mecha and undergo a multi-stage ultrasonic alcohol wash and calibrated 395–405nm UV post-curing cycle to achieve peak mechanical strength:

• Engineered for Load-Bearing & Friction: Formulated specifically for high-stress mechanical joints and gears with dramatically higher impact and wear resistance than standard resins.

• High Rigidity & Strength: Features a Young’s Modulus of 1900 MPa, Flexural Modulus of 1830 MPa, and Tensile Stress at Yield of 63 MPa (58 MPa at break) to resist flexing or snapping under the robot's weight.

• Impact & Shatter Resistance: Combines an 82 Shore D surface hardness with a 37% Elongation at Break and 50 J/m Notched IZOD Impact resistance, allowing the bracket to absorb sudden physical shocks without brittle fracturing.

• Thermal & Environmental Stability: Rated to a Heat Deflection Temperature (HDT) of 65°C at 0.455 MPa with low moisture absorption (2% over 24hrs) and ISO 10993-10 biocompatibility certification.

Important Disclaimer – Sold "As-Is" (No Warranty)

Please read carefully before purchasing:

1. Sold As-Is: These replacement parts are third-party, 3D-printed repair components and are sold strictly "as-is" without any warranty, guarantee, or post-sale technical commitment.

2. DIY Disassembly Required: Replacing Loona's internal leg brackets requires partial disassembly of the robot's leg and hip servo assembly. By purchasing this item, you acknowledge that you are performing the repair at your own risk. We are not responsible for any damage caused to your robot during disassembly, installation, or subsequent operation.

3. Not an Official KEYi Tech Product: This is an independent aftermarket replacement solution designed to help owners salvage and repair out-of-warranty or broken Loona units.
