This is the work.

Started as a vacuum-holding problem nobody had solved in PA12 CF at this geometry. Third generation failed on infill. The failure forced the breakthrough — overextrusion sealing, microporosity elimination, print-in-place barb geometry. Five hardware generations. Now ships.

Pump-free water methanol injection via choked flow. The question was whether tank pressure alone could drive atomization at useful velocities. It can. Nine generations of internal geometry refinement. Currently under revision — PPA failing under hose clamp compression and heat creep. PA12 CF next.

Custom CFD approximation using ray-cast geometry to derive drag coefficients, downforce estimates, and surface pressure heatmaps from STL files. Built because commercial CFD tools were inaccessible, not because the math was simple.

Dual tandem damper, pushrod-actuated rear suspension on a 2005 F150. Adjustable motion ratios. Laser-cut PA12 CF composite rockers with bronze bushings. Built in four months on a $500 BOM. Validates the manufacturing method and the design philosophy before either gets applied to the UF-1. One damper blew on output — currently being rebuilt with in-house printed valve blocks.

The post-runner. Proof of method. A pushrod suspension system that doesn't exist anywhere else at this price point on this platform. The red rocker is PA12 CF. The dampers are tandem. The geometry is adjustable. It works.

Born from the F150 build. A fully rebuildable monotube damper with a 3D printed flow-control valve block replacing a traditional shim stack. The geometry is the valving curve — adjustable by reprinting, not by sourcing. Donor bodies from the build. Matched pairs for tandem applications.

A staged-elastic bump stop for the post-runner — manage the terminal energy of a bottom-out so the last inch of travel isn't a frame-shock event, and return that energy instead of packing down. Rejected the thin buckling skin (hard TPU folds like paper at ~700 lbf). Rejected the solid crush puck the market sells. Landed on a thick graded annulus that compresses and bulges into its own open tapered bore, with a full-height Yoshimura diamond relief shaping the force curve into a plateau. Rev F prints as one watertight unibody, base-down, no supports. The physics is settled to first order; the printed-TPU modulus isn't — one compression coupon collapses a ~7× force uncertainty before any number gets trusted.

The reason this all started. A ground-up hypercar designed around driver experience, not economies of scale. DOM tube frame. In-house axial flux motors. A 2-stroke V8 with blow-diffuser scavenging, pulsejet assist, and compressed air supercharging. 3D printed carbon fiber and fiberglass body panels over printed molds. The F150 is the first proof of method. The UF-1 is the destination.
