JS Precision Case Study: Automotive Electronics Companies Save $860,000 In Development Costs With 3D Printing And Rapid Prototyping

Challenge

The automotive Tier 1 supplier which has global recognition needed to develop a new car center console knob which required five ergonomic tests and one vehicle test sample batch to be completed within three months.

The total cost of the traditional method included five CNC machining sessions which cost $12,000 each and injection mold development which cost $180,000.

The CNC machining process was unable to create the internal translucent texture structure which resulted in challenges for both appearance assessment and functional testing.

Solution

JS Precision developed a custom solution through their organization which integrated 3D printing technology with rapid prototyping and rapid tooling methods. The solution required two distinct steps to complete:

1. Prototype Verification:

High transparency resin knobs were printed using SLA technology, with layer thickness precisely controlled at 0.05mm.

The surface reached a roughness level of Ra1.2μm after three gradient polishing processes while the light transmittance achieved 91% which perfectly matched the light transmission effect and texture details of mass produced parts.

The researchers completed five rounds of ergonomic verification testing which resulted in all testing errors remaining within the range of ±0.03mm.

2. Small Batch Trial Production:

We team created a high precision silicone mold after successfully completing functional testing which used our optimized SLA part as the master mold. The mold tolerance was determined to be ±0.08mm.

The manufacturing process produced 50 sets of PC/ABS vehicle-mounted sample prototyping products which required only 12 minutes to create each individual part while achieving a 99.8% success rate.

Results

• The total project cost was reduced to $38,000 which saved $860,000 compared to the traditional solution while achieving a 96% cost reduction.
• The development cycle was shortened from 14 weeks to 4 weeks, and the client's PPAP review was passed two months ahead of schedule.
• Physical testing showed three design problems which included a light knob damping feel and uneven character backlighting, and the testing results enabled the team to make necessary mold changes which protected the production process frompotential defects.
• The team achieved first-time success in mass production because they used rapid mold verification data to predict material shrinkage which directly informed their steel mold design process.

This case fully demonstrates the practical value of 3D printing rapid prototyping services. If you also want to reduce costs and accelerate your product development, contact JS Precision immediately for a customized project solution.
