Reliable 3D printed parts from prototypes up to small batch production runs.

ProtoMech Engineering (Pty) Ltd bridges prototyping and production with functional FDM parts, avoiding tooling costs and long lead times.

Backed by years of production experience, we deliver FDM parts across consumer and engineering plastics for brackets, housings, clips, fixtures, and other low to medium volume needs.

Is 3D printed production a fit for your project?

As a guideline, 3D printing makes a lot of sense when you:

  • Need between a handful and a few hundred parts.
  • Want to avoid tooling costs or design freeze too early.
  • Have parts that would be complex or expensive to machine.

Services

From early prototypes to small production batches, ProtoMech Engineering combines CAD design and 3D printing to deliver practical, install-ready parts.

Print

Custom 3D printing

Upload your existing CAD files (STEP, STL, etc.) and we’ll prepare and print parts suitable for real-world use.

  • FDM production: PETG, ASA, PA6, PA12, CF-filled, Glass-filled, etc.
  • Functional prototypes & jigs
  • Short production runs
CAD

Design & engineering

No model yet? We can design from sketches, samples or a broken part, with manufacturing and assembly in mind.

  • Parametric CAD models
  • Design-for-print guidance
  • Technical drawings if needed
Fix

Replacement & repair parts

Reverse engineered parts for equipment where spares are expensive, slow to get, or no longer available.

  • Clips, latches, covers
  • Custom adapters & brackets
  • Improved designs over OEM
Batch

Low-volume production runs

Consistent batches of parts for internal products, trial kits, or ongoing low-volume requirements.

  • Repeatable quality
  • Flexible order quantities
  • Easy design updates between batches

Materials & capabilities

At ProtoMech Engineering, we specialise in FDM across consumer and engineering-grade plastics. If you need something specific, don't hesitate to reach out.

Consumer-grade materials

  • PETG and ASA for outdoor and general-use parts
  • PLA for quick mock-ups and fit checks
  • Color options available on request

Engineering-grade options

  • PA6 and PA12 for strength and durability
  • Carbon fibre-filled nylons for stiffness and heat resistance
  • Guidance on design-for-print and material selection

When is 3D printing a good alternative?

3D printing shines when you want flexibility and low upfront cost, rather than committing to tooling and large minimum order quantities.

Ideal scenarios

  • You’re validating a design and expect a few iterations.
  • You only need a small to medium quantity of parts.
  • Your parts are complex, with features that are awkward to machine.
  • You want the option to update the design between batches.

Typical quantities & price breaks

Every project is different, but as volumes increase we can often offer better pricing on identical parts.

Quantity Use case Indicative pricing behaviour
1–5 Prototypes / one-offs Per-part price highest; focus on speed and learning.
5–25 Pilot runs, fixtures & jigs More efficient build layouts reduce cost per part.
25–200+ Ongoing low-volume production Best opportunity for price breaks on repeat batches.

Advantages over traditional methods

3D printing won’t replace all manufacturing, but in the right context it can be faster, cheaper, and far more flexible than tooling-based approaches.

No tooling cost

You’re not paying for moulds or fixtures before you have a proven design. This is ideal when you’re still refining geometry or volumes are modest, especially for engineered plastics where iterations matter.

Faster iteration

Make changes between batches at minimal cost. This is especially useful when you’re getting feedback from real-world use.

Geometry freedom

Internal channels, organic shapes, integrated mounting features and other difficult geometries are often more practical with additive manufacturing than with subtractive or moulded parts.

Typical parts and applications

From simple brackets and clips to batches consisting of hundreds of parts—examples of the work we take on.

Small brackets and clips

Brackets, clips & mounts

Small parts

Small functional parts for holding sensors, cables or panels in place – ideal candidates for 3D printing where tooling would be expensive for low quantities.

3D printed electronic enclosures

Custom housings & enclosures

Electronics

Application-specific housings designed around your PCB and connectors, including mounting points, cable routing and branding where needed.

Batch of parts on 3D printer

Short-run batches of parts

Production

Sets of identical components produced in batches – ideal for in-house products, kits, or hardware you supply to your own clients.
