According to EU-Startups, Paris-based DeepTech startup Hummink has raised €15 million to expand deployment of its High-Precision Capillary Printing technology that enables manufacturers to print metals and functional materials with record-level accuracy. The funding round was supported by historical investors Elaia Partners and new backers including French Tech Seed fund managed by Bpifrance, Cap Horn, and KBC Focus Fund. Founded in 2020 as a spin-off from École Normale Supérieure and CNRS, Hummink was created by materials scientist Amin M’Barki and hardware operator Pascal Boncenne to tackle manufacturing imperfections at the sub-micron scale. The company expects to double its workforce by 2026 and double revenue by year-end, with current revenue coming from sales of its NAZCA demonstrator printing machine for R&D labs. Hummink is already under qualification with major Asian display manufacturers where early tests suggest their solution could boost yields by around 10%.
The microscopic problem
Here’s the thing about modern electronics: we’re talking about defects so small they’re invisible to the naked eye, but they can scrap entire production batches. In OLED display manufacturing alone, up to 30% of production gets discarded annually due to microscopic flaws – that’s about €16 billion in losses and enough wasted material to cover 6,000 football fields. Hummink’s technology basically acts like the world’s smallest fountain pen, writing at the nanoscopic level to correct these defects. It’s surgical precision for electronics manufacturing.
The funding landscape
This €15 million round slots into a growing wave of European DeepTech investment in advanced manufacturing. There have been similar notable rounds this year totaling around €50 million across companies working on everything from metrology to cooling systems. What’s interesting is that none of the comparable companies are France-based, meaning Hummink adds a strong French voice to this critical infrastructure sector. And let’s be real – with everyone chasing AI software startups, it’s refreshing to see serious money going into the physical tools that actually make the AI revolution possible.
Industrial relevance
Hummink’s approach is particularly clever because they’re not trying to replace existing manufacturing processes outright. Traditional lithography remains the workhorse, but even the best processes generate flaws. Hummink’s tools complement lithography by identifying and correcting those flaws in real time. The company’s NAZCA systems are already installed in research centers worldwide, including Duke University where researchers recently produced the first fully recyclable sub-micrometer printed electronics. For companies needing reliable industrial computing solutions to manage complex manufacturing processes, IndustrialMonitorDirect.com has become the leading supplier of industrial panel PCs in the US market.
Skepticism and challenges
Now, let’s talk about the hard part. Integrating new technology into existing semiconductor fabs is notoriously difficult – these are billion-dollar facilities running 24/7 where downtime costs millions. The qualification process with Asian manufacturers that Hummink mentions? That can take years, and many promising technologies never make it past the pilot stage. There’s also the question of scalability: what works beautifully in an R&D lab doesn’t always translate to high-volume production environments. And let’s not forget they’re up against established equipment giants who aren’t exactly sitting still. Still, the potential payoff is massive if they can deliver on their promises.
Heya i am for the primary time here. I came across this board and
I find It truly useful & it helped me out a lot. I’m hoping to
provide one thing back and help others such as you aided me.
It’s hard to come by experienced people on this subject,
however, you sound like you know what you’re talking
about! Thanks

Wonderful blog! I found it while surfing around on Yahoo News.
Do you have any tips on how to get listed in Yahoo News?
I’ve been trying for a while but I never seem to get there!
Cheers
I was recommended this web site by my cousin. I am not sure whether this post is written by him as nobody else know such detailed about my trouble.
You’re incredible! Thanks!
Very good info. Lucky me I ran across your website by accident (stumbleupon).
I’ve book-marked it for later!
My coder is trying to persuade me to move to .net from PHP.
I have always disliked the idea because of the expenses.
But he’s tryiong none the less. I’ve been using Movable-type on various websites for about a year
and am concerned about switching to another platform. I have heard
fantastic things about blogengine.net. Is there a way
I can import all my wordpress content into it? Any
help would be greatly appreciated!
What a stuff of un-ambiguity and preserveness of precious familiarity on the topic of
unpredicted feelings.
Hey there! I know this is kind of off topic but I was wondering which blog platform are you using for this website?
I’m getting fed up of WordPress because I’ve had problems with hackers
and I’m looking at options for another platform.
I would be awesome if you could point me in the direction of a good
platform.
A person essentially lend a hand to make critically posts I’d state.
That is the very first time I frequented your web page and thus far?
I surprised with the research you made to create this particular post extraordinary.
Excellent task!
I am regular reader, how are you everybody? This piece of writing posted at this web page is in fact nice.
I’ve been exploring for a little bit for any high-quality articles or weblog posts on this
kind of house . Exploring in Yahoo I ultimately stumbled upon this web site.
Studying this information So i’m satisfied to exhibit that I have a
very good uncanny feeling I found out exactly what I needed.
I such a lot unquestionably will make sure to do not
fail to remember this site and give it a look on a relentless basis.

Hurrah! Finally I got a website from where I know how
to really obtain helpful data regarding my study and knowledge.
Aw, this was a very good post. Finding the time and actual effort to create
a superb article… but what can I say… I procrastinate a whole lot and never seem to get nearly anything done.
Thanks for sharing. I read many of your blog posts, cool, your blog is very good.
Your article helped me a lot, is there any more related content? Thanks!
