Why do many lab-scale printed electronics fail to reach mass production?
A primary challenge in commercializing printed electronics is the significant gap between lab-scale development and high-volume manufacturing. A process that works perfectly in a controlled lab setting often does not directly translate to a roll-to-roll production line. Engaging with a manufacturing partner at the earliest stages of development is crucial to bridge this gap and co-develop a process that is inherently scalable from the start.
This early engagement enables the implementation of Design for Manufacturability (DfM) principles, a critical step for de-risking the product development cycle. A contract manufacturer provides invaluable input on material selection, suggesting substrates, conductive inks, and adhesives that are not only suitable for the application but also compatible with high-speed production processes. This foresight prevents costly and time-consuming redesigns that often occur when a product designed in isolation is brought to a factory.
The ideal manufacturing partner can support the entire product lifecycle, from initial concept and prototyping to full commercialization. They should have the flexibility to produce small batches for validation and clinical trials, as well as the capacity to seamlessly scale to tens of thousands or even millions of units. This ensures a smooth and efficient pathway from a promising idea to a successful commercial product.
In this short video, you can learn:
* The critical gap between lab-scale processes and mass manufacturing.
* How early Design for Manufacturability (DfM) input can de-risk your product development.
* What to look for in a partner to scale from concept to commercialization.
📋 **Clip Abstract** Successfully scaling a printed electronic device from the lab to millions of units requires early collaboration with a manufacturing partner. This ensures Design for Manufacturability (DfM) by aligning lab processes and material choices with high-volume production realities from day one.

Can printed electronics survive a 300% surge in its most critical conductive material?
Can printed electronics survive a 300% surge in its most critical conductive material?
Silver remains the uncontested conductive standard for printed electronics, but extreme market volatility poses severe challenges for contract manufacturers. With silver prices soaring over 300% from $28.92 to $121.67 per ounce, the cost of manufacturing components with high silver content—frequently exceeding 50% of the ink formulation—has skyrocketed.
This dramatic price inflation is compounded by geopolitical disruption and supply chain constraints, impacting raw materials beyond precious metals to substrates and functional fillers. Contract manufacturers are forced to work in tight collaboration with raw material vendors and customers to mitigate these cost increases without degrading device performance.
Addressing this issue requires balancing raw material innovation with production realities, especially in regulated industries where substitution is highly restricted. Finding a pathway to cost stability is critical for the long-term commercialization of flexible electronics, smart textiles, and medical biosensors.
In this short video, you can learn:
* The financial impact of the 300%+ increase in silver spot price on printed electronics manufacturing.
* Why silver remains the default material choice despite severe supply chain volatility.
* How geopolitical factors and raw material surcharges are inflating the costs of substrates and inks.
📋 **Clip Abstract** This clip examines the critical supply chain and cost challenges facing printed electronics due to a historic 300% surge in silver prices. Alicen Pittenger explains how this market volatility affects contract manufacturing and highlights the urgent need for material innovation.

Does doubling your screen printing speed simply shift the bottleneck to your curing ovens?
Does doubling your screen printing speed simply shift the bottleneck to your curing ovens?
In printed electronics manufacturing, scaling production and improving cost-effectiveness often relies on equipment upgrades and process optimizations. Integrating advanced print presses, like the Sakurai cylinder screen printing press, enables higher precision through integrated optical registration.
While doubling the run speed significantly increases factory throughput and output capacity, it introduces critical downstream process challenges. Manufacturers must verify if the thermal or UV curing systems can match the accelerated print speed without sacrificing the functional performance of the conductive ink.
For highly regulated industries like medical device manufacturing, any modification to the print speed or curing profile constitutes a process change that demands a complete system re-validation. This highlights the necessity of balancing equipment throughput gains with rigorous quality assurance protocols during scale-up.
In this short video, you can learn:
* How high-precision optical registration on modern print presses improves alignment and throughput.
* The challenge of balancing accelerated print speeds with downstream ink curing dwell times.
* The operational differences in validation requirements between industrial and medical printed electronics.
📋 **Clip Abstract** This clip explores how high-precision print presses can double production speeds and support large-scale commercialization in printed electronics. Alicen Pittenger details the technical challenge of ensuring that ink curing can keep pace with accelerated printing and the regulatory validation required for process changes.

How do you replace silver in medical-grade printed electronics when FDA clearance locks in your formulation?
How do you replace silver in medical-grade printed electronics when FDA clearance locks in your formulation?
Exploring alternatives to silver inks—such as silver-carbon blends, copper inks, silver-plated copper, and low-silver content formulations—presents a promising avenue for cost reduction. On paper, these alternative materials claim to maintain equivalent electrical conductivity and performance characteristics.
However, implementing these material changes is highly restricted for medical devices and biosensors that have already secured FDA clearance or commercial approval. For regulated medical applications, a formulation swap cannot be made overnight, demanding rigorous joint testing and feasibility validation between contract manufacturers and customers.
Transitioning to a lower-cost ink requires printing prototypes, conducting multiple rounds of physical and electrical testing, and confirming long-term reliability. Only through systematic feasibility analysis can alternative materials be validated as true one-to-one functional equivalents.
In this short video, you can learn:
* The primary material alternatives to silver, including copper, silver-plated copper, and carbon blends.
* Why regulatory approvals like FDA clearance prevent immediate material substitutions in medical electronics.
* The iterative testing and validation process required to transition commercial products to alternative conductive inks.
📋 **Clip Abstract** This clip highlights the technical and regulatory hurdles of replacing silver with cheaper alternatives like copper or low-silver inks in printed electronics. Alicen Pittenger discusses why "on-paper" equivalence must undergo rigorous, multi-round feasibility validation, particularly for FDA-regulated medical devices.
