ADDITIVE MANUFACTURING•PROTOTYPING•REVERSE ENGINEERING
Precision additive manufacturing, engineered to spec.
NEXA Manufacturing Co. partners with innovators and businesses to design, iterate, and manufacture high-quality custom products — from a single functional prototype to a low-volume production run.
SCROLL
The company
Advanced manufacturing, end to end.
NEXA Manufacturing Co. is an advanced additive manufacturing and product development company specializing in high-quality replacement parts, rapid prototyping, and production solutions for businesses across multiple industries.
We partner with machine shops, startups, and established companies to transform concepts into functional products through precision manufacturing and fast-turnaround prototyping. Alongside our B2B work, we design, manufacture, and distribute our own consumer products through direct-to-consumer channels, including Amazon.
We are also actively engaged in government contracting through SAM.gov, supporting public-sector procurement opportunities with innovative manufacturing capabilities and reliable production solutions.
Rapid Prototyping
Concept to functional part in days — visual review, fit checks, and stress testing.
Replacement Parts
Reverse-engineered from a damaged part when no CAD or OEM drawings exist.
Machine Shop Supply
Fixtures, jigs, tooling aids and low-volume components for shops that need them now.
D2C Product Brands
We design, manufacture and distribute our own consumer lines, including on Amazon.
Government Contracting
Active SAM.gov registered vendor supporting public-sector procurement.
Drone & UAV Development
Proprietary design, engineering and commercialization of next-generation platforms.
Small-Batch Production
No minimum order. One-off through low-to-mid volume production runs.
Where we're headed
Next-generation drone & UAV technology.
Our long-term focus includes the development of next-generation drone and UAV platforms, where we are investing in proprietary product design, engineering, and commercialization — alongside the structural components we already build for commercial UAV programs today.
Talk to engineering→Step 01 / 03
01
CAD Design
Every project starts with precise 3D modeling, matched to your exact specifications before a single layer gets printed.
Step 02 / 03
02
Weight Reduction
We redesign the inside of the part — removing material it doesn't need while keeping the strength it does — which is where the 46% weight reduction happens.
Step 03 / 03
03
Printed & Verified
We print in whatever material the application actually calls for, drawing from a wide range of engineering-grade options — then inspect the part and run it through load and vibration testing before it ships.

What we build
Three ways we take a part from idea to production.
Additive manufacturing lab based in Indiana — no traditional tooling, no long lead times.

Rapid Prototyping B2B
Move from concept to a physical model at speed — high-fidelity prototypes for visual review, stress-testing, and fit-checks, iterated in days instead of weeks.
Best for
Proof of concept, investor pitches, functional testing
Capability
High-resolution additive manufacturing
Private & Government Contracts GOV
We take on confidential production work for large institutions, municipalities, and government or defense clients — every file and part protected under NDA from the first conversation.
Best for
Government agencies, defense contractors, institutions needing strict confidentiality
Capability
NDA-restricted projects, one-off and low-volume runs
In-House E-Commerce Brands D2C
We design, build, and sell our own consumer product lines across Amazon, Etsy, eBay, and Walmart — so we know firsthand what it takes to ship a real product.
Best for
Seeing our end-to-end capability in a shipped product
Capability
Consumer product design, multi-channel fulfillment
Proof of work
Two jobs. Two very different clients.
The overwhelming majority of our work — commercial, industrial, and defense — is protected under NDA and never leaves the building. These two are the rare exceptions we're cleared to share.
REPORT NX-014 / AEROSPACENDA
Bracket weight reduction
Challenge
A commercial aerospace client needed a structural sensor-mount bracket lightened by 40%+ versus their existing CNC-machined aluminum part. Every gram saved compounds across a full production run — but the part still had to survive the same flight-certified load and vibration standards as the original.
Solution
Our engineers reworked the bracket's internal geometry from the ground up, removing material everywhere the load paths allowed it, and produced the final part in Carbon-Fiber Reinforced Nylon (PA-CF) for the stiffness-to-weight ratio the application demanded.
Result
46% weight reduction versus the original design, with load-bearing performance that matched — and in testing, exceeded — the original part. Passed vibration testing.

0%
REPORT NX-021 / HEAVY INDUSTRYNDA
Mill crane component, reverse-engineered
Challenge
A critical component on an overhead material-handling crane failed at a heavy industrial mill, halting production immediately. The original equipment manufacturer quoted a multi-week lead time for a replacement — with every day of downtime costing the plant real production.
Solution
We reverse-engineered the failed component directly from the damaged part — no drawings or CAD files from the OEM required — and produced a replacement in industrial-grade PA-CF, built to handle daily mill-floor impact and stress.
Result
Delivered and installed in under 48 hours, weeks ahead of the OEM's timeline. The part has been running under daily mill-floor stress ever since with zero failures.
Crisis to delivery

IP security
Every project is IP-secure — no exceptions.
We sign standard corporate and government NDAs before we ever open a file or CAD model. It's why most of what we build never appears on this website; if you don't see your industry above, assume we've probably built for it under an NDA we can't break.
