ORELTECH Technological FAQ


OrelTech has developed a new metallization technology, and every new technology raises questions. We gathered the most common ones below. If you have a follow-up question, please use the contact form, and we will get back to you shortly.
We are a Berlin-based company that developed a new technology and new conductive inks for printing electrodes and catalytic surfaces. We are looking for new customers. We are offering an alternative to production of many devices, such as OLEDs, sensors, transistors, batteries, solar cells, fuel cells, wearables, medical devices and many othe
Electrodes are an integral part of any electronic device, but methods for electrode deposition are outdated and often do not suit the customers' needs. High-temperature processes ruin delicate substrates, for example. Prince of materials is another huge problem, of course, with the price of electrodes reaching 80% of the price of the whole device. We offer an alternative way and solutions to these and many other problems.
We developed new nanoparticle-free metallization inks. Instead of using heat or UV laser to cure our inks we use cold plasma metallization to sinter the printed layers. That allows us to make the metallization process benign to the substrate, and the inks - quite practical.
Think about the difference between snow and ice. An established approach - nanoparticle inks - behave like snow. They deposit small particles on top of your surface, and then connect them together. In our approach metal behaves like ice: it grows directly on the surface. That means better adhesion, better cohesion, higher stability and lower roughness.
Our best customers are usually medium-sized companies that are developing new products, for example a novel wearable sensor, a printed OLED or a lab-on-a-chip, or looking for ways to improve existing ones. Someone who is willing to move quickly and innovate in order to stay competitive.
OLEDs, flexible electronics, medical devices, sensors.

Printing and Inks

Our inks are very versatile. They can be printed using a variety of ways, depending on your needs. If you need precision and intricate patterning, we offer inks for inkjet printing. If you have a 3-dimensional substrate, or just want to increase production speed, we offer aerosol sprayable inks. If you are looking for something in the middle, slot-die coating is also an option. We can adapt our inks to almost any known deposition method, based on your preferences.
That's ok too. We have a large ink library with inks suitable for many different substrates, ranging from glass to paper, and from PET to fabrics. We can find a good fit for your substrate, and if not, we can make a new ink especially for you. We have extensive R&D experience in suiting inks to, let's say tricky materials.

Plasma Metallization

Plasma metallization is a quick and simple process. It occurs at low temperatures - always below 70°C - and does not produce any liquid or solid waste. You can say that it is by far the greenest metallization process available today.
You do, but you have a large choice here. There are tens of plasma equipment providers, all around the world, who offer both off-the-shelf available and custom-made devices. Plasma equipment is both batch and roll-to-roll compatible, and is widely used in the electronics industry, for example, for surface cleaning. There is a chance you already have such a device in your line. We offer full support in choice of the most suitable instrument for you.
First of all, the operational expenses of plasma instruments are much lower, and you save money over time. And second, and maybe more importantly, lack of nanoparticles allows us to make our ink prices more reasonable. Nanoparticle synthesis is usually a large part of the ink price, and in our case we just don't need it. So, if you summarize these factors, you win quite a lot in the long run.


Our metal layers are very thin, usually not more than 300 nm, and thus very flexible. We have a lot of examples of our metal layers on plastic, paper and textile. They retain conductivity after tens of thousands of bends
No, our metal layers are very thin and flat. But we can coat 3D printed surfaces of any complexity.
Please contact us directly, and we will answer all your specific questions.
You can order a sample kit. It contains several examples of our metallized layers on various surfaces. It has a fixed price, and we can add extra samples if you have a special request. Please contact us to get a quote.
