ケーススタディ: LS Manufacturing は、自動車エレクトロニクス顧客のマルチカラー ステータス インジケーター シェルの 32% 節約にどのように貢献しましたか?
上位 100 社に入る自動車エレクトロニクス メーカーの 1 社は、インターフェースの亀裂と、マルチカラーのダッシュボード インジケーター シェルの製造コストの上昇という問題を抱えていました。オールポリジェットのプロトタイプから始めると部品あたりのコストは850 米ドルで、 振動耐久性テスト10～55Hz でのパフォーマンスも悪いものでした。 Optical clarity and impact resistance are necessary conditions for automotive 3D printing programs:
Client Challenge
The part needed a clear light guide bonded to a two-color over-molded grip region. All-polyJet shells cost USD 850 per unit and had bond line cracks during vibration testing from 10 to 55 Hz. Three design iterations led to a six-week delay for the project. Custom multi-color 3D printing service was not able to resolve the requirements for clarity and impact resistance separately.
LS Manufacturing Solution
The engineers divided the shell into two regions: an FDM process using a modified ABS body with tensile strength of 42 MPa, providing impact resistance, and polyJet process for the localized region of transparency with multi-color gradient. An interlocking rib-and-groove assembly with 0.05mm clearance substituted the bonding, getting rid of the weak interface that failed before. The industrial color 3D manufacturer used proper materials for proper functionality with 3D printing techniques.
Results and Value
Per unit costs were reduced from USD 850 to USD 578, representing a 32% reduction in cost. Impact strength was increased by 150%, meeting all of the automotive industry tests at the first try. Validation cycle time was reduced by 18 days, resulting in an annual production contract for the part. The final multi-color prototype quote reflected engineered value over process markup, bridging prototype into low-volume 3D printing fulfillment.

LS Manufacturing was able to reduce per unit cost by 32%, while eliminating vibration cracking and improving impact strength by 150% by using FDM in the impact zones and polyJet in the optical zones, which were precisely mated together. Additionally, time-to-market was reduced by 18 days, turning the prototype program into a production contract. This is a prime example of how end-use 3D printing experience pays off.
All-polyJet cost $850/part and failed vibration. Our hybrid FDM+polyJet approach cut cost by 32% and passed on the first try. Contact us for a hybrid-process quotation on your multi-color shell.
Multicolor prototyping can fall victim to material interface problems because of insufficient geometry between different plastics. Consistency in joint depth to be equal to or greater than 0.6mm and using of micro dovetails causes shear strength to be increased by more than 400% and saves time on iterations greatly. The 3D printing process involves the use of geometries as follows:

The above data allows making decisions about multi-color FDM vs polyJet 3D printing service choices because interface strength dictates what kind of the process will be applied. Shear-safe 3D printing needs quantifiable information about joint geometries.
<ブロック引用>
As the value of overlap joint depth is set to be ≥0.6mm and micro dovetail lock is added, interface shear strength will rise from 4-6MPa to 22-26MPa, thus increasing its efficiency by four times. That way, failure will be addressed in multi-color prototypes, which will lead to reducing tests by two times and saving on additional reworks up to 40%. For FDM multi-color prototype service, it becomes possible to have this geometry in use turning a weak point into a strong one.

How To Strategically Utilize Multi-Color Prototype Quote Comparisons To Compress Your Quarterly R&D Budget?
The comparison of multi-color prototype quotes without knowing their potential costs such as odor, cracking of recycled materials, deviation of ±0.5mm will increase your spending on the project. The strategy of ERP transparency in pricing and ISO 9001 quality will decrease your quarterly R&D budget up to 18%. This is how 3D printing starts:
Identify Low-Cost Traps Through Key Quality Indicators
Cheap manufacturers prefer using recycled pellets that emit fumes and crack beyond 50°C heat deflection temperature. Ask for material certification - for sure, with virgin resin, you get your tensile variation at ±3%. Also, tolerance of ±0.5mm is not enough for snap fit mating parts, make sure to get first article inspection report including tolerance of ±0.15mm or less. In this case, you immediately exclude from cooperation 60% of amateurs and save yourself USD 450 per incorrect shipment on average. 3D printing procurement process starts with that.
Leverage ERP-Driven Transparent Quoting to Expose Hidden Markups
ERP calculates material costs, machining costs, labor costs and overhead costs for each product separately, and this way you can compare products offered by different suppliers and discover overpriced purge waste and setup costs. The historical order management helps in providing automatic tiered pricing on repeated purchases and you see clearly where discounts are available. Using ERP information provided by the supplier, unit prices reduce up to 12-15% and thus you facilitate 3D printing cost reduction.
Validate Supplier Capability Against ISO 9001 Standards
ISO 9001 mandates traceable work instructions, calibration logs, and corrective action records. Certified facilities maintain first-pass yield above 92% versus the industry average of 78% (ASQ 2024 report). Asking for recent audit findings reveals which shops deliver consistent quality. You reduce incoming inspection time by 40% because predictable quality eliminates last-minute redesigns triggered by supplier errors. ISO-certified 3D printing partnerships ensure this reliability.
Use Comparative Quote Analysis to Negotiate Annual Contracts
Plot the unit cost, lead time, and defect rate of each vendor in a weighted scorecard focusing on total cost of ownership rather than the lowest starting bid. By presenting this information to your choice of vendor, you generally can negotiate 5-8% down to secure a one-year commitment. You lock in stable pricing and priority capacity, compressing quarterly R&D spend by 18% on average. This framework turns multi-color prototype quote comparisons from a price hunt into a value optimization exercise.

By filtering out vendors that use recycled materials, asking for transparent quotes in terms of ERP, requiring ISO 9001 certification, and requesting quotes from three different vendors, you cut back R&D budget for the quarter by up to 18%. This approach will turn multi-color prototype quote comparison into a value optimization exercise, making sure you get value for money and help your product launch process.
