At Stephens Plastic Mouldings, we understand that time-to-market and design confidence are critical to our clients’ success. That’s why our 3D prototype printing services are designed to help you evaluate, iterate, and refine your product design before committing to tooling or full-scale injection moulding production.
What Is 3D Prototype Printing?
3D prototype printing (also known as additive manufacturing) is a rapid prototyping method that uses digital CAD files to build parts layer-by-layer. This allows us to produce functional models or visual representations of your component without investing in injection mould tools.
Whether you’re validating form and fit or testing functionality, our 3D printing for plastic parts provides a fast and cost-efficient route to market.
Key Benefits of Using 3D Printing Before Tooling
1. Faster Design Validation
Get a tangible version of your product within days. This helps identify design flaws early, avoid tooling rework, and dramatically reduce the risk of costly production delays.
Want to ensure your design is mould-ready?
Our design for manufacture (DFM) support helps you optimise parts for injection moulding.
2. Cost-Effective Development
Avoid the high upfront investment of steel tooling by trialling concepts through 3D printing. It’s especially valuable for low-volume, custom, or pre-launch applications.
3. Functional Prototypes for Testing
Need a working prototype to test mechanical performance or assemble with other components?
We offer engineering-grade 3D printing materials to simulate real-world usage.
4. Supports Agile Development
By iterating quickly, you can respond to market feedback or regulatory requirements without delay – giving you a strategic edge in competitive industries.
5. Bridges the Gap Between Design and Production
Our clients often use 3D printing to communicate ideas across design, engineering, procurement, and marketing teams. This ensures alignment before final tooling begins.
How We Integrate 3D Printing Into Injection Moulding Projects
We don’t just offer 3D printing as a standalone service. At Stephens Plastic Mouldings, prototyping is embedded in our plastic injection moulding workflow, giving you complete development support from sketch to final product.
- Collaborative design reviews.
- Functional testing with sample assemblies.
- 3D printed enclosures, clips, fittings, and medical housings.
- Pre-production sampling before in-house tooling starts.
Our engineering team will guide you through prototype iteration, helping reduce waste, tooling time, and unit costs when your project scales.
Sectors That Benefit From 3D Prototyping
- Medical devices: arly-stage product trials, ergonomics.
- Automotive: Test components under stress or vibration.
- Electronics: Validate fit within housings.
- Industrial: Assess manufacturability before investment.
- Consumer products: Accelerate time to market for new designs.
We tailor our approach to your industry and application – ensuring speed, accuracy, and value every step of the way.

FAQs
1. How much does 3D prototype printing cost?
Costs depend on part size, complexity, and material, but 3D printing is significantly cheaper than injection mould tooling for initial samples. Contact us for a tailored quote.
2. Is 3D printing suitable for production parts?
While ideal for prototyping, 3D printing isn’t typically used for mass production. We offer it as a bridge to injection moulding services, which are more cost-effective at scale.
3. Can I test functionality with a 3D printed prototype?
Yes – our advanced printers use materials that simulate real-world properties. Perfect for mechanical, fit, or thermal testing.
4. How fast can I get a prototype?
We usually deliver 3D printed prototypes in 3 – 5 working days, depending on part complexity and volume.
5. Do you provide design support with prototyping?
Absolutely. Our team offers full design for manufacture (DFM) consultations to help you optimise your part for injection moulding.
