Summary of the clip:
Additive electronics are sustainable, but what's the #1 cost driver preventing mass adoption?
Despite achieving a significant 23% CO2 reduction on the electronic module, the project faced a major commercial hurdle: cost. The transition to Laser Direct Structuring (LDS) resulted in a 45% cost increase for the electronic module and a 10% increase for the final finished product. In a highly competitive market like consumer electronics, such a cost increase is a significant barrier to implementation.
A detailed cost breakdown reveals where the additional expense originates. The LDS-grade plastic carrier accounts for a quarter of the cost, with laser activation and metallization adding another 13% and 15% respectively. These process-specific costs are notable but are not the primary driver of the overall increase, showing that the core LDS technology is becoming more competitive.
The single largest cost component, representing nearly half (47%) of the total, is the Surface Mount Technology (SMT) assembly. Assembling electronic components onto a 3D, non-planar substrate is not a standard, high-volume process in the same way that it is for flat PCBs. This lack of a mature, scaled manufacturing ecosystem for 3D assembly is identified as the most painful and significant cost barrier for this technology.
In this short video, you can learn:
* The real-world cost impact of replacing a PCB with an LDS/MID solution.
* A percentage-based cost breakdown of the LDS manufacturing process (plastic, laser, plating, assembly).
* Why SMT assembly on 3D substrates is the biggest commercial challenge for Molded Interconnect Devices (MIDs).
📋 **Clip Abstract** Discover the commercial reality of implementing sustainable 3D electronics. This analysis breaks down the 45% cost increase, revealing that SMT assembly on non-planar surfaces—not the LDS process itself—is the biggest financial obstacle.

Decathlon's methodology for analyzing the CO2 impact of the Laser Direct Structuring (LDS) process is detailed in this clip. The analysis, conducted with an "open book" approach with their partners, breaks the process down into three key stages: plastic injection, laser structuring/activation, and the final metal deposition. This granular approach allows for a precise calculation of the ecological footprint for this additive electronics technology.
The analysis provides a direct comparison of environmental impact between a traditional Printed Circuit Board (PCB) and an LDS-manufactured circuit. To ensure a fair comparison, the study normalizes the data to one square centimeter of functional circuitry. This provides a clear, apples-to-apples benchmark between the two manufacturing technologies, isolating the impact of the substrate and metallization process.
The results of the life cycle analysis (LCA) are staggering. The LDS process demonstrates a nearly 84% reduction in climate change impact compared to a conventional PCB. This dramatic decrease, along with significant reductions in other environmental criteria, provided a powerful technical and business incentive for Decathlon to pursue the project further and validate the technology for their products.
In this short video, you can learn:
* How to break down the LDS process for a CO2 impact assessment.
* The quantitative environmental benefit of LDS technology over traditional PCBs.
* The importance of partner collaboration for accurate sustainability analysis.

How do you ensure a 3D plastic circuit dissipates heat as well as a traditional PCB?
How do you ensure a 3D plastic circuit dissipates heat as well as a traditional PCB?
The critical first step in this engineering challenge was to establish a reliable simulation model. The team measured the real-world thermal emissions of the existing product's standard PCB and then built a corresponding finite element analysis (FEA) model. The key was to correlate the simulation with reality, achieving an error margin of less than 5%, which was deemed acceptable to proceed with confidence.
With a validated simulation model, the team could effectively de-risk the transition to Laser Direct Structuring (LDS). Instead of costly and time-consuming physical trial-and-error, they could run numerous virtual iterations. This allowed them to explore a wide design space, testing different LDS-grade plastic materials, varying the thickness of the conductive metal layers, and optimizing the 3D geometry of the circuit traces.
The power of the simulation-led approach was in its ability to find an optimal solution that met the performance target. By mixing and matching different materials and design features within the simulation, the engineers were able to develop a final LDS part design. This design was proven virtually to provide a heat dissipation level at least equivalent to the original PCB, ensuring the product's electronic components would not overheat.
In this short video, you can learn:
* The methodology for creating and validating a thermal FEA model against real-world measurements.
* How simulation is used to iterate on material selection (plastics, metal thickness) for 3D electronics.
* The engineering process for ensuring thermal equivalency when replacing a PCB with an LDS part.
