Precision CNC Machining in
San Diego
Precision Manufacturing, Engineered from the Start.
Engineering-led CNC machining, prototyping, and manufacturing solutions for high-precision parts requiring tight tolerances and reliable turnaround.
Precision Engineered Solutions
12th Dimension Industries is a precision machine shop that specializes in engineered CNC manufacturing solutions, small batch prototyping, and full scale production of machined components. We work directly with engineers, designers, and manufacturers who need parts made right — with attention to detail, clear communication, and accountability.
We operate as an engineering-led, hands-on manufacturing shop, which allows us to stay closely involved in every project, remain flexible where it matters, and maintain consistent precision across all work we take on.
What We Do
Precision CNC Manufacturing tailored for your toughest projects.
Full Production Scaling
Advanced material processing solutions designed to optimize mass production and accelerate your manufacturing objectives.
Prototyping & Small Batch Production
Fast, reliable prototyping and short-run manufacturing for design validation and early production.
In-house engineering support to refine designs, improve manufacturability, and optimize processing before machining begins.
Design for Manufacturing Consultation
Why 12th Dimension
Where Engineering Leads Manufacturing.
12th Dimension Industries is engineer-owned and operated. That means every project is approached with an understanding of design intent, tolerances, and real-world manufacturing constraints — not just a set of dimensions on a print.
We don’t just cut parts. We think through them.
Clear Communication, Start to Finish
You work directly with the people making your parts. No account managers, no handoffs, no guessing.
If something can be improved, we’ll tell you.
If something needs clarification, we’ll ask.
If a timeline changes, you’ll know early.
That transparency saves time, cost, and frustration.
Precision Where It Matters
We specialize in steel and aluminum parts that require tight tolerances, repeatability, and careful execution. Our processes are built around accuracy, consistency, and attention to detail — whether we’re machining a single prototype or a small production run.
Quality is built into the way we work


Creative Problem Solving
Not every part is straightforward — and that’s where we do our best work.
We regularly help customers refine designs, improve manufacturability, and solve fabrication challenges before machining begins. This collaborative approach reduces rework and leads to better outcomes.
What This Means for You
Parts made right the first time
Direct access to technical insight
Reasonable pricing for precision work
Reliable turnaround without cutting corners
If you value accuracy, communication, and thoughtful execution, 12th Dimension Industries is a strong fit.
Hands on Manufacturing by Design
We operate as an Independent Precision Workshop. That allows us to:
Stay extremely flexible and agile
Provide direct customer communication
Maintain high accountability and quality focus
Foster a sense of community both internally and with our customer
If a project fits our capabilities, we’ll treat it with care. If it doesn’t, we’ll be honest about it.
Have a Part in Mind?
If you’re working on a part that requires accuracy, consistency, and clear communication, we’re happy to take a look.
Whether it’s a prototype, a small batch, or a challenging design that needs a second set of eyes, we’ll tell you honestly if it’s a good fit.
Industries We Serve
We support a range of industries where precision, reliability, and attention to detail matter. While our capabilities are broad, our focus remains the same across every project: accurate parts, clear communication, and dependable execution.
Aerospace
We support aerospace projects where precision, consistency, and disciplined execution are critical. Our manufacturing approach emphasizes tight tolerances, careful planning, and reliable results for performance-driven applications.
Defense
We support defense-related manufacturing programs requiring accountability, process discipline, and dependable execution. Our work focuses on producing components that meet defined requirements and perform as intended.
We support medical projects where accuracy, repeatability, and controlled execution matter. From early development through production support, we work closely with teams to produce parts that meet precise specifications.
Medical
A Flexible, Capability-Driven Approach
If your project requires precision machining and fits within our capabilities, we’re happy to discuss it — regardless of industry.
Industrial
We manufacture components for industrial applications where reliability, fit, and function are essential. Our approach emphasizes consistent execution and clear communication to support equipment, tooling, and production systems.
Automotive
We support automotive projects from development through production, with a focus on repeatability and production awareness. Our manufacturing process is designed to deliver consistent results as requirements and volumes evolve.
How We Work
A Clear, Thoughtful Process
We keep our process simple, transparent, and engineering-driven. Every project is handled with the same attention to detail — from initial review through final delivery.


What You Can Expect
Direct communication with the people making your parts
Honest feedback and realistic timelines
Careful execution with attention to detail
A shop that takes responsibility for its work
1. Review & Understanding
We start by reviewing your design, requirements, and constraints. If something looks unclear or can be improved, we’ll flag it early. Our goal is to fully understand design intent before machining begins.
2. Feedback & Quoting
Once the scope is clear, we provide straightforward feedback, realistic timelines, and fair pricing. If adjustments can improve manufacturability or reduce cost, we’ll walk through those options with you.
No surprises. No vague estimates.
3. Precision Machining
With everything aligned, we machine your parts carefully and deliberately. We focus on accuracy, repeatability, and process discipline — whether it’s a single prototype or a small production run.
Quality is built into the process, not rushed at the end.
4. Delivery & Follow-Through
Parts are delivered as promised. If there are questions, revisions, or future iterations, we stay involved and responsive.
Our work doesn’t end when the part leaves the machine.
