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.
As a guideline, 3D printing makes a lot of sense when you:
Not sure where your project fits? Send a description below and we'll advise whether 3D printing is a good option.
From early prototypes to small production batches, ProtoMech Engineering combines CAD design and 3D printing to deliver practical, install-ready parts.
Upload your existing CAD files (STEP, STL, etc.) and we'll prepare and print parts suitable for real-world use.
No model yet? We can design from sketches, samples or a broken part, with manufacturing and assembly in mind.
Reverse engineered parts for equipment where spares are expensive, slow to get, or no longer available.
Consistent batches of parts for internal products, trial kits, or ongoing low-volume requirements.
A straightforward process from first contact to parts in your hands — no surprises, no design freeze.
Send us a description, sketch, sample, or existing file. If you're not sure exactly what you need, that's fine too — we'll help scope it out.
We'll review your requirements, suggest the best material and approach, and send you a clear quote — typically within one business day.
Once approved, we print, inspect, and post-process your parts. Most orders are ready within 3–7 business days.
Parts are shipped nationwide via courier, or available for local collection. Your files are kept on record for easy reorders.
We specialise in FDM across consumer and engineering-grade plastics. Not sure which material fits your application? We'll advise during quoting.
| Material | Category | Strength | Temp. resistance | Typical use cases |
|---|---|---|---|---|
| PLA | Consumer | ~60 °C | Fit checks, visual mock-ups | |
| PETG | Consumer | ~80 °C | General parts, enclosures, clips | |
| ASA | Consumer | ~90 °C | Outdoor parts, UV-resistant housings | |
| PA6 (Nylon) | Engineering | ~120 °C | Load-bearing parts, wear components | |
| PA12 (Nylon) | Engineering | ~130 °C | Flexible, durable, good chemical resistance | |
| PA-CF (Carbon Nylon) | Engineering | ~150 °C | Structural, stiff, high heat & load demands |
Consumer-grade materials are available in a range of colours on request. Engineering-grade materials are typically black or natural. Post-processing options include sanding, priming, and painted finishes for parts with appearance requirements.
We print parts up to approximately 350 × 350 × 400 mm in a single piece. Larger assemblies can be split and bonded. Typical dimensional tolerances are ±0.2–0.5 mm depending on geometry and material.
3D printing shines when you want flexibility and low upfront cost, rather than committing to tooling and large minimum order quantities.
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. |
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.
You're not paying for moulds or fixtures before you have a proven design. Ideal when you're still refining geometry or volumes are modest.
Make changes between batches at minimal cost. Especially useful when you're getting feedback from real-world use.
Internal channels, organic shapes, integrated mounting features and other difficult geometries are often more practical with additive manufacturing than with subtractive or moulded parts.
From simple brackets and clips to batches of hundreds of parts — examples of the work we take on.
Small functional parts for holding sensors, cables or panels in place – ideal candidates for 3D printing where tooling would be expensive for low quantities.
Application-specific housings designed around your PCB and connectors, including mounting points, cable routing and branding where needed.
Sets of identical components produced in batches – ideal for in-house products, kits, or hardware you supply to your own clients.
We let results speak — here's what some of the people we've worked with have to say.
"Replace this with a real client quote. Describe the service received, quality of the parts, turnaround time, or anything that stood out about the experience."
"Replace this with a real client quote. Focus on something specific — a problem that was solved, a material recommendation that worked, or a fast turnaround that saved the day."
"Replace this with a real client quote. Even one or two sentences from a satisfied client carries significant weight for new visitors making a decision."
ProtoMech Engineering (Pty) Ltd was founded to bridge the gap between design and production for engineers, product developers, and small businesses who need functional parts fast — without the overhead of large-scale manufacturing.
Based in Cape Town, South Africa, we combine hands-on engineering experience with a practical approach. We work closely with each client to make sure the material, geometry, and process are right for the application — not just the easiest path to print.
You deal directly with the engineer doing the work — no intermediaries, no miscommunication.
We understand tolerances, loads, and real-world fit — not just how to operate a printer.
If 3D printing isn't the right solution for your project, we'll tell you — and point you in the right direction.
