3D Printing Parts for the real world, based in Southampton

As an industrial additive manufacturing UK partner, we focus on engineering 3D printing and low volume manufacturing for real functional parts, not hobby kits or generic marketplace fulfilment.

Your Parts Are Made To Order

Every order is assessed around use: load, heat, moisture, wear, surface finish, tolerance and quantity. That keeps the recommendation specific to the job instead of relying on generic 3D printing claims.

Automotive, defence, marine, architecture, product design, and maintenance teams use us when they need a part that solves a defined problem, not just a print from a file.

This focused model keeps us away from low-margin commodity fulfilment and towards projects where careful material selection, CAD review, and clear advice make the difference between a useful component and a failed print.

Instant quotes for production-ready parts

Use our instant quote platform to upload an STL file or CAD model and get an online 3D printing quote for low volume manufacturing. This is the fastest way to compare costs for production additive manufacturing, engineering prototypes, and custom plastic components.

Whether you need an instant additive manufacturing quote, upload STEP file quote, or instant pricing for functional 3D printed parts, we make it simple to move from CAD to manufacture.

Industries We Support

• Automotive

  Automotive engineering demands speed, precision, and flexibility. 3D printing helps manufacturers, restorers, and engineering teams move from concept to finished part quickly without expensive tooling or long lead times. From rapid prototyping and functional testing to reverse engineering obsolete components and producing low-volume production parts, additive manufacturing offers a practical solution for modern automotive challenges. Whether supporting motorsport, heritage vehicle restoration, electric vehicle development, or specialist engineering projects, we provide engineering-led 3D printing solutions designed to improve performance, reduce costs, and accelerate development.

Engineering Plastics and Material Selection

Material choice is where many 3D printed parts succeed or fail. We select polymers around service conditions such as load, heat, UV exposure, moisture, wear, chemical contact, flexibility, and surface finish.

The goal is practical reliability. Emergency replacements need to restore function quickly; production parts need repeatability and lifespan; visual models need clean detail without paying for unnecessary engineering-grade material.

• Materials explained: Materials are where 3D printing becomes engineering, not just production. Each material has its own mechanical properties, finish, and use case.
• PLA: Best suited for visual models and light-use parts. Easy to print and cost-effective, but not designed for high-stress or high-temperature environments.
• ABS: Stronger and more heat-resistant than PLA. Suitable for functional prototypes and parts that need durability without moving into engineering-grade materials.
• PETG: A balance between strength and flexibility. Good for functional parts where impact resistance and chemical resistance are required.
• Nylon (PA12): An engineering-grade material. Strong, flexible, and wear-resistant. Used for functional components, mechanical parts, and assemblies.
• Resin (SLA): High-detail, smooth finish. Ideal for intricate parts, visual prototypes, and applications where surface quality matters.
• Composite materials: Carbon fibre or glass-filled materials offer increased stiffness and strength. Used where weight and performance are critical.

Cost of 3D Printing UK

The cost of 3D printing is not a fixed price. It is a calculation.

It depends on several key factors:

• Material usage, including volume and density
• Print time and machine hours
• Labour and setup
• Post-processing requirements
• Quantity

Unlike traditional manufacturing, there are no tooling costs, but that does not mean every part is cheap.

For small batches, prototypes, and complex geometries, 3D printing is often more cost-effective than machining or injection moulding. For high-volume production, traditional methods may still be more economical.

What matters is understanding where it fits. If you are producing one-off parts, custom components, or low-volume runs, 3D printing reduces upfront investment and speeds up delivery.

It is not about price alone. It is about total cost of production, time, and flexibility.

For procurement teams, predictability matters. Once a part has been proven in service, repeat orders can be produced consistently, with known material, finish, and tolerance expectations.

This is particularly useful where legacy equipment is still operational but no longer supported by the original manufacturer. It allows businesses across Hampshire and the South Coast to extend asset life without redesigning an entire system.

Based in Southampton, Mitchell & Son supports businesses throughout the Solent region that need fast, sensible manufacturing solutions. Injection moulding has its place, but the upfront costs often run into thousands before a single part is produced.

For low-volume, emergency, or discontinued components, additive manufacturing is often the only commercially sensible option. We also offer post-processing where required, including sanding, surface finishing, and reinforcement, to improve durability or appearance when needed.

These services are optional and applied only where they add real value. The objective is always the same: produce a part that works properly, fits correctly, and does its job without becoming the next problem.

Everything we do is driven by real-world use. If a part is ornamental, it can be produced cheaply and quickly. If a part is handled daily, subjected to force, or critical to safety, it is built accordingly.

We do not oversell materials or processes that are unnecessary, and we do not underspec parts that will fail prematurely. This approach has allowed us to support manufacturers, engineers, restorers, and maintenance teams across Southampton and Hampshire with solutions that make practical and financial sense.

When something breaks, the priority is getting it working again reliably, not experimenting with technology for its own sake.

If you are dealing with a breakdown, an obsolete component, or a supply issue that cannot wait, 3D printing provides a fast and flexible solution. By combining practical experience, CAD capability, and material knowledge, we are able to produce functional parts without the cost and delay of traditional manufacturing methods.

The goal is not just to print a part, but to solve the problem that caused the failure in the first place.
