Validation of the design at an early stage is critical for success

Alternative: additive manufacturing

• Small series

• Undiscovered ways of engineering

• Larger series too expensive

• Limited amount of materials

• Materials properties not representative for injection moulding Ironbridge UK

Why P3D?

PRIM

Focus: To bridge the gap from single prototypes in prototyping materials to injection molded production series in final material

Goal: Better validation of the design before critical investments

How? 3D printing of molds and injection molding knowhow

A process called PRIMPRinted Injection Molding

Product case

PRIM product case - Quooker

High quality Cold Water Filter development

• Quooker cold water filter (UK market )

• Rubber button (integrated led indicator)

• P3D produced several small PRIM series for testing of button

PRIM product case - Quooker

Development steps in Quooker development

PRIM prototypes for:

• Snap fits

• Touch and feel (difficult/impossible using 3D printed prototypes)

• Pressure feeling (Testing different hardness's of the materials)

• Transparency for the led light & covering interior of the product

Conclusions Quooker using PRIM

• PRIM supported Quooker to build experience on product development and manufacturing using soft materials in a very short time

• “Prototyping using different techniques (3D printing, vacuum casting) did not give a conclusive result”

• “Thanks to PRIM, we have been able to go through several iterations in a short time”

• “after finishing the last PRIM prototype we could quickly continue with production, the feasibility was already demonstrated with the prototypes”

Capabilities

Materials

High tolerance / complex geometry / big products

Medium tolerance / ordinary geometry / medium-sized products

Low tolerance / simple geometry / small products

• Shrinkage comparable to regular injection molding

• Continuously testing new materials

Capabilities

• Mold buildup• No ejector pins• No specific mold cooling• No slides

• Product complexity• multiple inserts possible > undercuts possible• Manual operation

• Part geometry• Draft angles 2 degrees or more• No sharp corners minimum radius 0,5

Summary

Advantages of PRIM

• High level validation of design in early development stage

• Large range of functional materials available

• Short lead-time (approximately 1 week)

• Low costs (depending on design €1500 - €3000)
