Case Studies

Complex projects, solved

A look at real client builds — the challenge, our approach, and the final result.

UAV Aerodynamic Bracket Run
Aerospace Drone Manufacturer

UAV Aerodynamic Bracket Run

Challenge

A 50-unit production run needed brackets with smooth aerodynamic surfaces and tight mating tolerances to a carbon spar.

Solution

ABS parts vapor-smoothed to remove layer drag, with heat-set inserts for repeatable spar attachment. Batch oriented to share support material.

Result

Surface roughness reduced below Ra 1.6 µm; full 50-unit run delivered in 6 days.

Outdoor Sensor Enclosure
Environmental Monitoring Startup

Outdoor Sensor Enclosure

Challenge

Enclosure required UV stability, weather sealing, and a branded cosmetic finish for a field-deployed sensor array.

Solution

ASA selected for UV resistance, vapor-smoothed for seal integrity, then paint-finished with the client brand color and clearcoat.

Result

Passed 500-hour UV exposure test; 200 units deployed across 4 climates.

Investment-Casting Turbine Pattern
Industrial Turbomachinery

Investment-Casting Turbine Pattern

Challenge

A low-volume turbine blade needed a casting pattern with a smooth, defect-free surface to produce a clean ceramic shell.

Solution

PLA pattern printed at 0.1 mm layer height, then hand-finished and sealed to investment-casting standard. Split into two halves for shell removal.

Result

Pattern produced a flawless ceramic shell; final cast blade met dimensional spec.

Production Fixture System
Electronics Assembly House

Production Fixture System

Challenge

A set of assembly jigs needed precise cable routing, snap-fits, and thread inserts across 12 different fixture variants.

Solution

PETG fixtures with embedded heat-set inserts, living-hinge cable clips, and consolidated multi-variant print scheduling to cut setup cost.

Result

Per-unit fixture cost cut 38% versus machined equivalents; full set delivered in 4 days.
