The speed of metal additive manufacturing.
The precision of CNC machining.
Our RIPL™ process builds stainless-steel parts with features down to 25 microns — complex internal geometry that CNC tools cannot reach and MIM tooling cannot afford, from first prototype to full production without retooling.
Start where your work starts.
An engineer wants the tolerances. Procurement wants the paperwork. A program lead wants to see it in a device. Pick your door — each one goes straight to the answer.
Design past the tool
Understand RIPL tolerances, feature sizes, and how micro parts behave at production scale — before you compromise the geometry.
Supplier basics
Lead times (~24 h quote, 2–4 week delivery), capacity from 1 to 100,000+ parts, ISO 13485, material datasheets and the supplier documentation an approval workflow asks for.
See it in a device
Where RIPL parts already work inside robot-assisted surgical systems and interventional devices — and where they fit your device.
RIPL™, by the numbers
Key performance ranges for design and evaluation. Final values depend on geometry, material, and application.
±0.0006″ tolerances
Typical; scales with part size
Ra 32 µin finish
Native surface, as sintered — no post-processing
25 µm features
Minimum feature size, as printed
5 µm resolution
Voxel and layer thickness
2–5 mm typical part size
Where RIPL parts work best
1 to 100,000+ parts
Same process from prototype to production — no retooling
Devices keep getting smaller. The metal parts inside them have to keep up.
Robot-assisted surgery and catheter-based intervention are where that pressure is greatest — and where RIPL parts are produced today.
Robot-Assisted Surgical Solutions
The constraint: Articulating systems demand precise motion from compact, complex assemblies — geometries that fracture sub-0.25 mm CNC tools.
What RIPL changes: Instrument, end-effector, joint, and structural components, each printed as a single net-shape part with the internal features the mechanism actually needs.
Interventional Device Solutions
The constraint: Catheter-based systems shrink the envelope while the functional demands keep growing.
What RIPL changes: Electrodes, tips, housings, and delivery-system components with thin walls and enclosed channels that fit constrained internal pathways.
