The Dcubed Milli Release Nut (mD3RN) is a Shape Memory Alloy (SMA) based release actuator designed to secure sensitive equipment during launch and safely release it on orbit. The Milli Release Nut constrains tensile axial loads and represents one of the smallest, most powerful Hold Down and Release Mechanism (HDRM) solutions on the market. They are easily resettable, allowing for repeated use across numerous test campaigns. **Key Features** TRL: 4 (9 in 2026) On-Ground Resettable, 100 times (TBC) Short Delivery Time Smart SMA Trigger Ultra Low Shock Axial Load (Release Load): 18 kN Body Size: Ø 56 x 55 mm Mass: 225 grams Body material: Hard anodized Aluminum 6082-T6 and Titanium grade 5 Nut material: Inconel 718 Temperatures: -65°C to +75°C Customizable Interfaces **Export Control** The Dcubed Milli Release Nut (mD3RN) is ITAR Free.
