3D Printing for Engineering Firms: Jigs, Fixtures & Proof of Concepts

In the world of engineering, time is money, and precision is everything. Whether you’re designing components, testing fit and function, or streamlining production processes, having the right tools on hand makes a big difference. That’s where 3D printing comes in.

At Shop3D, we work with engineering firms across the UK to supply custom jigs, fixtures, and proof of concept prototypes, delivered quickly, affordably, and with the accuracy professionals expect.

Why Engineering Teams Are Turning to 3D Printing

Traditional manufacturing is often too slow or expensive for rapid iteration and custom tooling. With 3D printing, engineers can:

  • Prototype mechanical parts in days, not weeks
  • Print one-off jigs and fixtures tailored to specific projects or processes
  • Test form, fit, and function before committing to metal tooling
  • Produce low-volume parts without high MOQ or lead times

This makes 3D printing ideal for both R&D and day-to-day operational needs.

What Engineering Firms Use Us For

Here are some common engineering applications we support:

  • Assembly Jigs & Fixtures: Lightweight, durable, and easy to redesign
  • Tooling Aids: Alignment tools, spacers, brackets
  • Proof-of-Concept Models: Fully functional or visual prototypes
  • Casing & Enclosure Mockups: For electronics, instrumentation, or control panels
  • Short-Run End-Use Parts: Non-load-bearing parts or stopgap components
  • Sensor & Camera Mounts: For robotics, drones, or test rigs

No tooling costs, fast revisions, and UK-based support means less downtime and faster progress.

Engineering-Grade Materials

We offer a range of materials suitable for functional engineering applications:

  • PETG: Strong, chemical-resistant, ideal for fixtures and casings
  • ABS: Tough and impact-resistant, perfect for prototypes and test rigs
  • Nylon: High strength, abrasion-resistant
  • TPU: Flexible and durable for soft mounts or grips
  • PLA: Cost-effective for visual models or early testing

Need something specific? Just ask, we’ll recommend the right material for your job.

Why Engineering Firms Trust Shop3D

We know speed, precision, and confidentiality matter. That’s why we offer:

  • Fast UK turnaround
  • Competitive pricing for short runs and batches
  • NDA-friendly service for sensitive projects
  • Feedback on file quality and printability
  • Support for STL, STEP, and CAD formats

Whether you’re part of a design consultancy, manufacturing plant, or engineering start up, we’re here to help you move faster.
