The pinnacle of structural efficiency

By combining the full strength of carbon fiber with the geometric optimization attainable with our multi-axis printing capability, we can make parts far lighter than the best existing alternatives.Our 5-axis machine runs carbon fibers directly along load paths and around fastener locations for stronger, stiffer, lighter parts. Unprecedented system integration and even entirely novel meta- properties for specialized applications is achievable.Strong. Optimized. Mantis.

Standard Size and Precision

With a 17 inch diameter* and 15 inch height, our build volume can accommodate a wide range of complex components currently limited to machined aluminum or titanium.Our machine is capable of maintaining a dimensional accuracy of +/- .1mm (.004in), and features can be post-machined to even better tolerances. Post machining coating options available for galvanic isolation, durability, lubricity, or aesthetics.*maximum size of fully 5-axis reinforced parts is smaller by 2-3 inches in each dimension. Contact us if you need to go larger.

Automated Design and Optimization Software

At Mantis, we are building a suite of tools that allow customers to upload, customize, and order parts in one simple step. Of course, we are always available for consultation or assistance.

Advanced Analytics and Part Traceability

Fabricating a high performance part is about more than just the geometry and the material.At Mantis, we are developing software that allows us to both predict and verify final part performance before the part ever leaves our facility.Each part is individually developed and qualified for its specific high-performance application. When your business is on the line, you can count on the performance of Mantis parts.Quality assurance: material-level design, first article testing, unit level testing, micro computed tomography, digital twins.
