Our Services

Mechanical Design
01 / DESIGN

Mechanical Design & Engineering

Need a custom part designed? We create detailed 3D models and engineering drawings for manufacturing. Whether you're starting from a sketch or need to reverse-engineer an existing part, we handle the technical details.

  • Custom part design from your specs
  • Converting 2D drawings to 3D models
  • Reverse engineering & 3D scanning
  • Design for 3D printing optimization
Additive Manufacturing
02 / 3D PRINTING

Additive Manufacturing

We use professional-grade 3D printers to create functional parts—not just models. Perfect for prototypes, custom tooling, or small production runs where traditional manufacturing doesn't make sense.

  • Functional prototypes that actually work
  • Custom jigs, fixtures, and tooling
  • Small-batch production parts
  • Professional materials and finishes
Prototype Development
03 / FABRICATION

Prototype Development & Assembly

Sometimes a project needs more than just 3D printing. We can weld, machine, and fabricate to complete your prototype—bringing together multiple processes to get you a finished result.

  • Welding and metal fabrication
  • Prototype assembly
  • Multi-process solutions
3D Scanning
04 / SCANNING

3D Scanning & Mesh Processing

Need to capture an existing part digitally? We use 3D scanning to create accurate digital models of physical objects, then process that data into clean, usable CAD files for manufacturing.

  • 3D scanning of existing parts
  • Scan data cleanup and processing
  • Converting scans to manufacturable models
  • Creating CAD files from physical samples
CLIENT FEEDBACK

What Our Clients Say

"Outstanding craftsmanship and exceptional end products. This level of attention to detail is not easy to find in a machine shop. I highly recommend!"

— John Smigaj

"As a contract Engineer at NorthWestern Energy I was tasked with finding solutions for LED light fixture retrofits. Coordinating with MT3D proved to be the one stop shop solution. MT3D successfully designed, tested, and manufactured thousands of custom shields and adapters. Orders were fulfilled and delivered in a timely fashion to warehouses across the state and quality was top notch."

— Ben Rostocki, NorthWestern Energy

Ideal Projects

When We're The Right Fit

We work best with clients who value precision and engineering expertise

You'll Get Great Results If:

  • You need engineering input and not just CAD execution
  • The project benefits from additive manufacturing or custom tooling
  • You have a defined problem to solve with measurable success
  • Quality and reliability matter more than lowest unit cost
  • Documentation and repeatability are important

We May Not Be The Best Choice If:

  • You need high-volume production (we focus on low-volume/tooling)
  • Price is the primary decision factor
  • Scope is undefined or requirements keep changing
  • You're looking for machine-time rental without engineering
  • You need instant turnaround on complex work

Not sure if we're the right fit? Let's talk. We'll be honest about whether we can deliver value on your project - even if that means pointing you toward another solution.

How We Work

Our Approach

Engineering First, Always

You get better results when engineering judgment guides the process from day one. We don't just execute your design - we validate manufacturability, suggest optimizations, and ensure the final part meets real-world requirements. This reduces costly revisions and gets you to a working solution faster.

Defined Scope, Predictable Outcomes

Every project starts with clear deliverables and success criteria. You'll know exactly what you're getting, when, and for what cost. No scope creep, no surprise charges, no ambiguity. This protects your budget and timeline.

Additive Where It Makes Sense

We leverage additive manufacturing for complex geometries, rapid iteration, and custom tooling that traditional methods can't match economically. If conventional machining is better for your application, we'll tell you. The goal is the right solution, not forcing every problem into one process.

Built for Repeatability

Whether it's a production fixture or a functional prototype, everything we design prioritizes consistent, measurable results. Documentation, tolerances, and testing protocols are included - not afterthoughts.
