Unlocking Medical Innovation with Micro-Precision Metal Components.

No other metal manufacturing process can meet Trio's precision, speed, cost, and quality.

Trio Labs' mission is to improve lives by enabling the next generation of medical devices. Trio fabricates precision metal parts with unmatched fine resolution and low cost using proprietary processes and tools that scale seamlessly from prototyping though high volume manufacturing. The patent-pending Resin Infused Powder Lithography (RIPL) process reduces costs and manufacturing times for existing products, and enables wholly new solutions in a wide range of medical device markets. Previously impossible devices and components are made routine by RIPL, including less invasive higher precision surgical tools, miniaturized infusion pumps, microneedle arrays, drug delivery devices, orthopedic implants, and more.

Unsurpassed Precision

Existing high-speed technologies can only produce rough parts that require expensive finishing in order to be functional. Trio's RIPL systems can produce high precision, finished, functional parts while maintaining production speeds. Parts directly meet the physical requirements of the majority of medical devices, eliminating costly post processing.

Design Flexibility

Additive Manufacturing has long been a favorite of design engineers for its ability to produce complex geometries. RIPL brings this design flexibility to a production level, allowing for previously impossible devices to be made in high volume.

Speed, speed, speed

RIPL digital fabrication eliminates week and month-long design cycles with rapid prototyping and near-zero startup cost. Best of all, prototypes and production parts are made the same way, eliminating time consuming and expensive transfer to volume manufacturing.

Resin Infused Powder Lithography (RIPL)

RIPL was designed from the ground up to address unmet needs in the medical device industry, providing ultra precision small metal parts with rapid turnaround, serving needs from single prototypes to million-part manufacturing runs. RIPL breaks the speed and expense barriers posed by existing CNC micro-machining. It uses industry-standard metal and ceramic powders as used used by Metal Injection Molding (MIM), but in a true Additive Manufacturing Process, combining all the benefits of 3D Printing with the speed of MIM and the precision of CNC. Feature Precision of 5 microns and fine surface finish are achieved without the need for additional post-processing. Prototypes can be shipped within 24 hours and high volume runs use the same process, simplifying development and manufacturing.

Industrial Grade Materials

RIPL is fundamentally compatible with any alloy or ceramic currently used in Powder Injection Molding (PIM).

Stainless 17-4 Titanium 6-4
Stainless 316/316L Alumina
Stainless 410 Zirconia
Stainless 420 Tungsten Carbide
Stainless 440c Silicon Nitride
Stainless 15-5 Silicon Carbide

Stainless steels, carbon steels, tool steels, bronze, copper, titanium, alumina, zirconia, and many other materials can be printed by RIPL with the same high level of detail and precision. Custom alloys and emerging new materials can also be quickly adopted by RIPL. Trio's unique processing also results in industry-leading final part density and mechanical properties, closely matching bulk properties.
